• Why are my videos playing speeded up with no audio, but work fine if I log in as a guest?

  - by Martins Kruze

  Since the start of this week I have been experiencing a glitch in the multimedia on my Samsung R518 laptop. I have 2 problems: Videos in every player are speeded up around 2 or 4 times (including youtube.com (both HTML5 and flash variants), any other video on the web and videos on my laptop played by Totem Media Player), exception is VLC player, but 2nd problem does concern even that. There is no sound - simple as that (with or without headphones plugged in). These all problems are now, and has not seen before, I upgraded to Ubuntu 10.10 after it was possible, and from start I didn't have anything from this - it just started in this week. I haven't even putted new software in. I have more or less solved the question (kind of) - I just logged in as a guest - and it all works, but when I make a new user - it does not. Please help me.

• Cannot play windows WMA lossless files on Rhythmbox

  - by sr71

  I have installed Ubuntu 10.10 with all its updates (without Windows) on it’s own drive and everything is working fine. I want to play WMA audio files, also mp3 files. The mp3 files play fine. The WMA files do not play. Used "Rhythmbox Music Player" with and without "Ubuntu-restricted" -extras. Still does not play the lossless windows audio files. I am frustrated with searching to play a WMA file ("download this converter"), but one cannot use this until one "deletes this". I have done everything but it still does not play my windows lossless files that I made from all my CD’s. I am looking for a music player that I can use to play mp3’s and WMA lossless music files and automatically put the album cover on and update the info if one exists. Installation should be as simple as possible. Right now I am back to the original virgin Ubuntu 10.10 with all the recent updates. This computer will do nothing but play music (mp3 and WMA) through a stereo system. I also use Internet to update album info for the music. I do not care what bells and whistles the music player program has, as long as it is an easy install and just plays my mp3 and wma lossless music files. Any help would be appreciated.

• Client-Server MMOG & data structures sync when joining / playing

  - by plang

  After reading a few articles on MMOG architecture, there is still one point on which I cannot find much information: it has to do with how you keep in sync server data on the client, when you join, and while you play. A pretty vague question, I agree. Let me refine it: Let's say we have an MMOG virtual world subdivided into geographical cells. A player in a cell is mostly interested in what happens in the cell itself, and all the surrounding cells, not more. When joining the game for the first time, the only thing we can do is send some sort of "database dump" of the interesting cells to the client. When playing, I guess it would be very inefficient to do the same thing regularly. I imagine the best thing to do is to send "deltas" to the client, which would allow keeping the local database in sync. Now let's say the player moves, and arrives in another cell. Surrounding cells change, and for all the new cells the player subscribes, the same technique as used when joining the game has to be used: some sort of "database dump". This mechanic of joining/moving in a cell-based MMOG virtual world interests me, and I was wondering if there were tried and tested techniques in this domain. Thanks!

• Detecting walls or floors in pygame

  - by Serial

  I am trying to make bullets bounce of walls, but I can't figure out how to correctly do the collision detection. What I am currently doing is iterating through all the solid blocks and if the bullet hits the bottom, top or sides, its vector is adjusted accordingly. However, sometimes when I shoot, the bullet doesn't bounce, I think it's when I shoot at a border between two blocks. Here is the update method for my Bullet class: def update(self, dt): if self.can_bounce: #if the bullet hasnt bounced find its vector using the mousclick pos and player pos speed = -10. range = 200 distance = [self.mouse_x - self.player[0], self.mouse_y - self.player[1]] norm = math.sqrt(distance[0] ** 2 + distance[1] ** 2) direction = [distance[0] / norm, distance[1 ] / norm] bullet_vector = [direction[0] * speed, direction[1] * speed] self.dx = bullet_vector[0] self.dy = bullet_vector[1] #check each block for collision for block in self.game.solid_blocks: last = self.rect.copy() if self.rect.colliderect(block): topcheck = self.rect.top < block.rect.bottom and self.rect.top > block.rect.top bottomcheck = self.rect.bottom > block.rect.top and self.rect.bottom < block.rect.bottom rightcheck = self.rect.right > block.rect.left and self.rect.right < block.rect.right leftcheck = self.rect.left < block.rect.right and self.rect.left > block.rect.left each test tests if it hit the top bottom left or right side of the block its colliding with if self.can_bounce: if topcheck: self.rect = last self.dy *= -1 self.can_bounce = False print "top" if bottomcheck: self.rect = last self.dy *= -1 #Bottom check self.can_bounce = False print "bottom" if rightcheck: self.rect = last self.dx *= -1 #right check self.can_bounce = False print "right" if leftcheck: self.rect = last self.dx *= -1 #left check self.can_bounce = False print "left" else: # if it has already bounced and colliding again kill it self.kill() for enemy in self.game.enemies_list: if self.rect.colliderect(enemy): self.kill() #update position self.rect.x -= self.dx self.rect.y -= self.dy This definitely isn't the best way to do it but I can't think of another way. If anyone has done this or can help that would be awesome!

• Create indefinitely oscillating pendulum in Farseer Physics 3.3.1/Box2d

  - by GONeale

  I am new to Farseer Physics and using version 3.3.1. I am after some help and would even be happy to receive Box2d answers just to ensure I get a response as I should then be able to convert it! -- Thanks ...After a lot of tinkering around I have managed to produce a thin vertical rectangle shape on the screen and I wish this to swing back and forth pinned at the top up to an angle I set (90 degrees would be fine for this sample). When it is approaching the top I wish it to slow down, then fall back the way it just came, increase speed then obviously slow to a stop at the top again. Almost how a swinging pirate ship would work at a theme park. This is the code I have so far which swings the shape, but it is seeming to lose speed on each swing eventually grinding to a halt: float playerWidth = ConvertUnits.ToSimUnits(5), playerHeight = ConvertUnits.ToSimUnits(68); playerPosition = ConvertUnits.ToSimUnits(-350, 0); playerBody = BodyFactory.CreateRectangle(World, playerWidth, playerHeight, 2f, playerPosition); playerBody.BodyType = BodyType.Dynamic; // create player sprite based on player body _rectangleSprite = new Sprite(ScreenManager.Assets.TextureFromShape(playerBody.FixtureList[0].Shape, MaterialType.Player, Color.Orange, 1f)); // Create swinging joint var joint = JointFactory.CreateFixedRevoluteJoint(World, playerBody, ConvertUnits.ToSimUnits(0, -34), playerBody.Position); If somebody could also provide the command I would need to pause the shape on a mouse click or keyboard command at it's current angle and then continue when I let go of the mouse click that would be super fantastic! (I actually posted this on StackOverflow as well before I realised there was a dedicated game development forum) Cheers

• Upgrade to 0.25, files served to uPNP devices cannot play

  - by David Buttrick

  I have a Sony BDP-S390 bluray & network player. I upgraded my Myth server to 0.25. When I browse to the Myth server, and try to play a recording, I get an error message about the file not being payable in the player. Interestingly, the files that i have recorded, and the videos that I have loaded into my Video volume group are .mpg or .mp4. The player shows the filetype that it thinks the file is in it's list, and it claims that these files are AVI files, however none of them are. They are all .mp4 or .mpg files. Thinking that that was just an optical illusion, I went ahead and tried to play a file, but I get an error about the file not being playable. First of all, is there something that I need to do to make the uPNP server know about different filetypes? Is it reporting AVI because it hasn't been told about MPG or MP4? Second, I'd like to help out some more here and collect some logging about the uPNP server in the myth server. I cant seem to find information on how to turn on logging, and there is no mythbackend settings file int /etc/default. Thanks very much.

• How to blend the sprite into background?

  - by optimisez

  I try to blend the character into game but I still cannot remove the blue color in the sprite sheet and discover that the white area of sprite is semi-transparent. Before that, the color D3DCOLOR_XRGB(255, 255, 255) is set in D3DXCreateTextureFromFileEx. You will see the fireball through the sprite. After I change the color to D3DCOLOR_XRGB(0, 255, 255), the result will be Now, I am trying to remove the blue color of the sprite sheet and my expected result is something like that Until now, I still cannot figure out how to do that. Any ideas? void initPlayer() { // Create texture. hr = D3DXCreateTextureFromFileEx(d3dDevice, "player.png", 169, 44, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(0, 255, 255), NULL, NULL, &player); } void renderPlayer() { sprite->Draw(player, &playerRect, NULL, &D3DXVECTOR3(playerDest.X, playerDest.Y, 0),D3DCOLOR_XRGB(255, 255, 255)); } void initFireball() { hr = D3DXCreateTextureFromFileEx(d3dDevice, "fireball.png", 512, 512, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255), NULL, NULL, &fireball); } void renderFireball() { sprite->Draw(fireball, &fireballRect, NULL, &D3DXVECTOR3(fireballDest.X, fireballDest.Y, 0), D3DCOLOR_XRGB(255,255, 255)); }

• How to code Time Stop or Bullet Time in a game?

  - by David Miler

  I am developing a single-player RPG platformer in XNA 4.0. I would like to add an ability that would make the time "stop" or slow down, and have only the player character move at the original speed(similar to the Time Stop spell from the Baldur's Gate series). I am not looking for an exact implementation, rather some general ideas and design-patterns. EDIT: Thanks all for the great input. I have come up with the following solution public void Update(GameTime gameTime) { GameTime newGameTime = new GameTime(gameTime.TotalGameTime, new TimeSpan(gameTime.ElapsedGameTime.Ticks / DESIRED_TIME_MODIFIER)); gameTime = newGameTime; or something along these lines. This way I can set a different time for the player component and different for the rest. It certainly is not universal enough to work for a game where warping time like this would be a central element, but I hope it should work for this case. I kinda dislike the fact that it litters the main Update loop, but it certainly is the easiest way to implement it. I guess that is essentialy the same as tesselode suggested, so I'm going to give him the green tick :)

• Generic rule parser for RPG board game rules - how to do it?

  - by burzum

  I want to build a generic rule parser for pen and paper style RPG systems. A rule can involve usually 1 to N entities 1 to N roles of a dice and calculating values based on multiple attributes of an entity. For example: Player has STR 18, his currently equipped weapon gives him a bonus of +1 STR but a malus of DEX -1. He attacks a monster entity and the game logic now is required to run a set of rules or actions: Player rolls the dice, if he gets for example 8 or more (base attack value he needs to pass is one of his base attributes!) his attack is successfully. The monster then rolls the dice to calculate if the attack goes through it's armor. If yes the damage is taken if not the attack was blocked. Besides simple math rules can also have constraints like applying only to a certain class of user (warrior vs wizzard for example) or any other attribute. So this is not just limited to mathematical operations. If you're familiar with RPG systems like Dungeon and Dragons you'll know what I'm up to. My issue is now that I have no clue how to exactly build this the best possible way. I want people to be able to set up any kind of rule and later simply do an action like selecting a player and a monster and run an action (set of rules like an attack). I'm asking less for help with the database side of things but more about how to come up with a structure and a parser for it to keep my rules flexible. The language of choice for this is php by the way.

• Faster 2D Collision detection

  - by eShredder

  Recently I've been working on a fast-paced 2d shooter and I came across a mighty problem. Collision detection. Sure, it is working, but it is very slow. My goal is: Have lots of enemies on screen and have them to not touch each other. All of the enemies are chasing the player entity. Most of them have the same speed so sooner or later they all end up taking the same space while chasing the player. This really drops the fun factor since, for the player, it looks like you are being chased by one enemy only. To prevent them to take the same space I added a collision detection (a very basic 2D detection, the only method I know of) which is. Enemy class update method Loop through all enemies (continue; if the loop points at this object) If enemy object intersects with this object Push enemy object away from this enemy object This works fine. As long as I only have <200 enemy entities that is. When I get closer to 300-350 enemy entities my frame rate begins to drop heavily. First I thought it was bad rendering so I removed their draw call. This did not help at all so of course I realised it was the update method. The only heavy part in their update method is this each-enemy-loops-through-every-enemy part. When I get closer to 300 enemies the game does a 90000 (300x300) step itteration. My my~ I'm sure there must be another way to aproach this collision detection. Though I have no idea how. The pages I find is about how to actually do the collision between two objects or how to check collision between an object and a tile. I already know those two things. tl;dr? How do I aproach collision detection between LOTS of entities? Quick edit: If it is to any help, I'm using C# XNA.

• Animating sprites in HTML5 canvas

  - by fnx

  I'm creating a 2D platformer game with HTML5 canvas and javascript. I'm having a bit of a struggle with animations. Currently I animate by getting preloaded images from an array, and the code is really simple, in player.update() I call a function that does this: var animLength = this.animations[id].length; this.counter++; this.counter %= 3; if (this.counter == 2) this.spriteCounter++; this.spriteCounter %= animLength; return this.animations[id][this.spriteCounter]; There are a couple of problems with this one: When the player does 2 actions that require animating at the same time, animation speed doubles. Apparently this.counter++ is working twice at the same time. I imagine that if I start animating multiple sprites with this, the animation speed will multiply by the amount of sprites. Other issue is that I couldn't make the animation run only once instead of looping while key is held down. Someone told me that I should create a function Animation(animation id, isLooped boolean) and the use something like player.sprite = new Animation("explode", false) but I don't know how to make it work. Yes I'm a noob... :)

• Sub-systems in game engines

  - by Hillel

  So here's the problem- I'm writing my own engine library, and it works fine with stuff like menus and the actual game screen. The thing is, I can't really figure out how to integrate something like an intro or dialogue preceding certain levels into this system. Let's look at another example- say I have a game-specific engine which gets a Level object and runs it. Engine would have its own collision and physics system, all hard coded. Now, what if at some point in a level, I want the player to enter a mini-game with different rules? How do I morph the Engine class to support these sub-systems without having to deal with their code all the time (as in: if(regular game) ... else if(mini game) ...)? And what if I want an intro animation at the start of a level, and I want the player to be able to assume control of his character once the animation ends, do I implement the animation into the Engine class itself? Or maybe I need to run another class, CutScene, and when it ends, it calls Engine and starts the level? What if I want to add a dialogue system, where at the start of each level there's a short dialogue and the player can't control his character, and once it ends, he can? Would I then run the dialogue code inside the Engine code? Maybe these sub-systems should all be scripted? I don't know anything about scripting, is it necessary for this kind of situation? Any help would be appreciated.

• Separate collision mesh model?

  - by Menno Gouw

  I want to have another go at 3D within XNA. What I have seen from some other games that they just have a separate very low poly model "cage" around the environment model. However I can not find any reference to this. I have not that much experience with XNA 3D either. Is it possible to have this cage within each of my environmental models already? Lets just say I call the mesh within the .FBX wall and col_wall. How would I call to these different meshes within XNA? The player would just have a tight collision cube around. To make it a bit more efficient I will be making divide the map up by cubes and only calculate collision if the player is in it. Question two: I can't find anywhere to do cube vs mesh collision. Is there a method for this? Or perhaps it is possible to build my collision cage out of cubes in the 3D app and on loading of the models in XNA replace them directly by cubes? So I could just do box to box collision which should be very cheap and still give the player the ability to move over ledges on the static models.

• How to optimize a box2d simulation in action game?

  - by nathan

  I'm working on an action game and i use box2d for physics. The game use a tiled map. I have different types of body: Static ones used for tiles Dynamic ones for player and enemies Actually i tested my game with ~150 bodies and i have a 60fps constantly on my computer but not on my mobile (android). The FPS drop as the number of body increase. After having profiled the android application, i saw that the World.step took around 8ms in CPU time to execute. Here are few things to note: Not all the world is visible on screen, i use a scrolling system Enemies are constantly moving toward the player so there is alaways to force applied to their body Enemies need to collide between each others Enemies collide with tiles I also now that i can active/desactive or sleep/awake bodies. Considering the fact that only a part of the enemies are possibly displayed on screen, is there any optimizations i can do to reduce the execution time of box2d simulation? I found a guy trying an optimization based on distance of enemies from the player (link). But i seems like he just desactives far bodies (in my case, i could desactive bodies that are not visible). But my enemies need to move even when they are not visible on screen, and applying forces will not workd on inactive bodies. Should i play with sleeping bodies here? Also, enemies are composed by two fixtures and are constantly colliding with each others and with tiles but i really never need to get notified about that. Is there anything i can do to optimize this kind of scenario? Finally, am i wrong to try to run simulation at 60FPS on mobile and should i try to make it run at 30FPS?

• Efficient Algorithm for Recording gameplay's objects positions

  - by Scorch

  So, I have a game idea in mind, and for that I need to record the game around the player. I'me not talking about recording it as video, but rather recording the scene objects, and their positions within the game, and then render them, giving the player the ability to go back and forth, to stop time and move around. I've made a prototype with some data structures in C#, since this is going to be the programming language we'll be using in our game, but if we want the player to be able to go back just five minutes back with the data of just 100 NPC's, it takes almost 1GB of RAM. Right now, I'm just storing a Doubly linked list, each item with the object position. In the game, I'll need to store even more data in each node, so I need something even more ligher. Of course, this algorithm is zero optimized, but still, that is a lot. The alternatives would be create the NPC's that aren't really important to the game when the user is viewing the past, but I don't really like it very much for the sake of realism. I wonder if there is a better way to store this? Thanks in advance, Scorch

• Using 2d collision with 3d objects

  - by Lyise

  I'm planning to write a fairly basic scrolling shoot 'em up, however, I have run into a query with regards to checking for collision. I plan to have a fixed top down view, where the player and enemies are all 3d objects on a fixed plane, and when the enemy or player fires at the other, their shots will also be along this fixed plane. In order to handle the collision, I have read up a bit on collision detection in 3d, as it is not something I have looked into previously, but I'm not sure what would be ideal for this situation. My options appear to be: Sphere collision, however, this lacks the pixel precision I would like Detection using all vertexes and planes of each object, but this seems overly convoluted for a fixed plane of play Rendering the play screen in black and white (where white is an object, black is empty space), once for enemies and once for the player, and checking for collisions that way (if a pixel is white on both, there is a collision) Which of these would be the best approach, or is there another option that I am missing? I have done this previously using 2d sprites, however I can't use the same thinking here as I don't have the image to refer to.

• Free movement in a tile-based isometric game

  - by xtr486

  Is there a reasonable easy way to implement free movement in a tile-based isometric game? Meaning that the player wouldn't just instantly jump from one tile to another or not be "snapped" to the grid (for example, if the movement between tiles were animated but you'd be locked from doing anything before the animation finishes). I'm a really beginner with anything related to game programming, but with the help of this site and some other resources it was quite easy to do the basic stuff, but I haven't been able to find any useful resources for this particular problem. Currently I've improvised something close to this: http://jsfiddle.net/KwW5b/4/ (WASD movement). The idea for the movement was to use the mouse map to detect when the player has moved to a different tile and then flip the offsets, and for the most part it works correctly (each corner makes the player move to wrong location: see http://www.youtube.com/watch?v=0xr15IaOhrI, which is probably because I couldn't get the full mouse map work properly), but I have no illusions that it is even close to a good/sane solution. And anyway, it's mostly just to demonstrate what kind of a thing I'd like to implement.

• Provide A Scrolling "Camera" View Over A 2D Game Map

  - by BitCrash

  I'm in the process of attempting to create a 2D MMO type game with Kryonet and some basic sprites, mostly for my own learning. I have the back end set up great (By my standards) and I'm moving on to actually getting some things drawn onto the map. I cannot for the life of me figure out a solid way to have a "Camera" follow a player around a large area. The view pane for the game is 640 x 480 pixels, and each tile is 32x32 pixels (Thats 20 tiles wide and 15 high for the viewpane) I have tried a couple things to do this, but they did not seem to work out so well. I had a JScrollPane with 9 "Viewpane"-sized canvases in it, and tried to have the JScrollPane move in accordance with the player. The issue came when I reached the end of the JScrollPane. I tried to "Flip" canvases, sending the canvas currrently drawing the player to the middle of the 9 and load the corresponding maps onto the other ones. It was slow and worked poorly. I'm looking for any advice or previous experience with this; any ideas? Thank you! Edit and Clarification: I did not mean to mention Kryonet, I was merely providing peripheral information in case there was something that would help which I could not foresee. Instead of having an array of 9 canvases, why not just have one large canvas loading a large map every once in a while? I'm willing to have "load times" where as with the canvas array I would have none (in theory) to give the user a smooth experience. I could just change the size and location of the map with a modified setBounds() call on the canvas in a layered pane (layered because I have hidden swing items, like inventories and stuff) I'll try it out and post here how it goes for people asking the same question.

• colliding btRigidBody objects behave strangely when moving slowly

  - by Piku

  I'm trying to use Bullet Physics in my iOS game. The engine appears to be correctly compiled in that the demos work fine. In my game I have the player's ship and some enemy ships. They're defined as btRigidBody objects and btCollisionObjects and I'm using btSphereShapes for collision. At 'fast' speeds, collisions appear to happen sensibly - things collide and nothing goes 'weird'. If the speeds are very slow though and the player's ship touches a non-moving object the collision happens, but then the player's ship moves at incredible speed over the next few frames and appears a long distance from where it collided - completely out of proportion to the speed it was moving before impact. To move the things around I'm using setLinearVelocity() each frame, ticking the physics engine, then using getMotionState() to update the rendering code I have. Part of the issue might be I don't quite understand how to set the correct mass or what the best speeds are to use for anything. I'm mostly sticking numbers in and seeing what happens. Should I be using Bullet in this way, and are there any guidelines for deciding on the mass of objects? (am I right in assuming that in collisions heavier objects will force lighter objects to move more)

• Collider2D and Rigidbody2D, how do they work?

  - by user42646

  I have been learning JavaScript and Unity for a week now. I learned how to make Cube as a Ground and another Cube as a player and I used this code to make the Player Cube move forward and backward and jumping var walkspeed: float = 5.0; var jumpheight: float = 250.0; var grounded = false; function Update() { rigidbody.freezeRotation = true; if (Input.GetKey("a")) transform.Translate(Vector3(-1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetKey("d")) transform.Translate(Vector3(1, 0, 0) * Time.deltaTime * walkspeed); if (Input.GetButton("Jump")) { Jump(); } } function OnCollisionEnter(hit: Collision) { grounded = true; } function Jump() { if (grounded == true) { rigidbody.AddForce(Vector3.up * jumpheight); grounded = false; } } I also learned how to make a character hit box. how to make a sprite and animation. pretty much the basic stuff. Couple of days ago I created simple ground in Photoshop and a simple character and imported them to Unity3D. Whenever I use my code above the character keeps falling from the scene. Like the character has nothing to stand on. After thinking about it it make sense because I really didn't make anything to make the player character understand that he should stand on something so I started reading about this issue and I realized that there is something called Collider2D and Rigidbody2D. Now I'm really stuck here I just don't know what to do. I applied the rigibody2d to my character picture and the Collider2D to the ground picture but whenever I play the project the gravity makes my character falls down. This is my question: How can I make the rigibody2d object realize that it shouldn't fall if there is a Collider2D object under it? So when I jump it's going to jump and the gravity going to bring it back to the ground.

• EventDispatcher between an as and an fla?

  - by Christopher Richa

  Hi everyone. I am making a fighting game in Flash and while I have everything running, I am missing something: a victory/loss screen. Logically, I know how to do it: if character.hp < 0 { character.dead = true; dispatchevent("death", event) } My problem is that I have no idea as to how to code it. I know I will use two classes and my two .fla files (unless I am wrong). I have two .fla files that are in play here: the Menu.fla file and the Arena.fla file. Menu.fla contains the entire navigation of the game, options, character selection screens, etc. and when it is time for the player to engage in battle, it loads the Arena.fla file, which contains only the backgrounds (depending on the selected stage) and for now is set to a length of one frame only. For Arena.fla, the real action happens in my classes, but logically, I would only need HP.as and Character.as. In Character.as, I have declared the following variable: var isDead:Boolean = false; //is character dead? In HP.as, believe I should have the following: if(currentHp<0) { currentHp = 0; character.isDead = true; //declared as var `character:Object;` EventDispatcher.dispatchEventListener("playerDead", playerDead); } And finally, in Arena.fla, I want to be able to detect the above-mentioned eventlistener and simply move on to a second frame which will display a message in the style of "PLAYER ONE HAS WON" or "PLAYER ONE HAS LOST" with a button that will allow me to go back to the character selection screen. This is the first part in which I am stuck: how do I detect the dispatched event listener in my main .fla file? Secondly, if the player clicks on the "CONTINUE" button, which displays regardless if the player has won or lost, how can my Menu.fla (which loads the Arena.swf) detect this click event, unload the game, and go back to the character selection screen? Thank you in advance for helping me out. I realize this is a lot of text but it's the most descriptive I can be. If you have any questions or need any clarification concerning my question, feel free to speak up. -Christopher

• controlling threads flow

  - by owca

  I had a task to write simple game simulating two players picking up 1-3 matches one after another until the pile is gone. I managed to do it for computer choosing random value of matches but now I'd like to go further and allow humans to play the game. Here's what I already have : http://paste.pocoo.org/show/201761/ Class Player is a computer player, and PlayerMan should be human being. Problem is, that thread of PlayerMan should wait until proper value of matches is given but I cannot make it work this way. Logic is as follows: thread runs until matches equals to zero. If player number is correct at the moment function pickMatches() is called. After decreasing number of matches on table, thread should wait and another thread should be notified. I know I must use wait() and notify() but I can't place them right. Class Shared keeps the value of current player, and also amount of matches. public void suspendThread() { suspended = true; } public void resumeThread() { suspended = false; } @Override public void run(){ int matches=1; int which = 0; int tmp=0; Shared data = this.selectData(); String name = this.returnName(); int number = this.getNumber(); while(data.getMatches() != 0){ while(!suspended){ try{ which = data.getCurrent(); if(number == which){ matches = pickMatches(); tmp = data.getMatches() - matches; data.setMatches(tmp, number); if(data.getMatches() == 0){ System.out.println(" "+ name+" takes "+matches+" matches."); System.out.println("Winner is player: "+name); stop(); } System.out.println(" "+ name+" takes "+matches+" matches."); if(number != 0){ data.setCurrent(0); } else{ data.setCurrent(1); } } this.suspendThread(); notifyAll(); wait(); }catch(InterruptedException exc) {} } } } @Override synchronized public int pickMatches(){ Scanner scanner = new Scanner(System.in); int n = 0; Shared data = this.selectData(); System.out.println("Choose amount of matches (from 1 to 3): "); if(data.getMatches() == 1){ System.out.println("There's only 1 match left !"); while(n != 1){ n = scanner.nextInt(); } } else{ do{ n = scanner.nextInt(); } while(n <= 1 && n >= 3); } return n; } }

• Animation using AniMate with Unity3D doesn't interact with physical objects

  - by Albz

  I'm designing a maze with Unity3D. The maze has a number of bifurcations and the player will stop before each bifurcation and simply choose left or right. Then an automatic animation will move the player through the next bifurcation till the end of the maze (or till a dead end). To animate the player I'm using AniMate and C# in my Unity project. Using AniMate I'm simply creating a point-to-point animation for each bifurcation (e.g. mage below: from the start/red arrow to point 5) My problem is that my animation script (associated to the "First Person Controller") is not working properly since physics is not respected (the player passes through walls). If in the same project I enable the standard character controls in Unity, then I can navigate in the maze with the physical contrains of walls etc... (i.e. I have colliders). This is an example of the code I'm using when I press left to pass from starting point, trough point 1 to point 2: void FixedUpdate () { if (Input.GetKey(KeyCode.LeftArrow)) { //To point 1 Hashtable props = new Hashtable(); props.Add("position", new Vector3(756f,112f,1124f)); props.Add("physics", true); Ani.Mate.To(transform, 2, props); //To point 2 Hashtable props2 = new Hashtable(); props2.Add("position", new Vector3(731f,112f,1124f)); props2.Add("physics", true); Ani.Mate.To(transform, 2, props2); } } What happens practically when I press the left arrow button is that the player moves directly to point 2 using a straight line passing through the wall. I tried to pass to AniMate "Physics = true" but it doesn't seem to help. Any idea on how to solve this issue? Alternatively... any hint on how to have a more optimized code and just use a series of vector3 coordinates (one for each point) to obtain the simple animation I want without having to declare new Hashtable(); etc... every time? I chose AniMate simply because 1. I'm a beginner with Unity 2. I don't need complex animations (e.g. I don't need to use iTween), just fixed animations along straight lines and I need something really simple and quick to implement in a script. However, if someone has an equally simple solution it will be welcome. thank you in advance for your help

• PHP - JSON Steam API query

  - by Hunter

  First time using "JSON" and I've just been working away at my dissertation and I'm integrating a few features from the steam API.. now I'm a little bit confused as to how to create arrays. function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530'); $test = decode_url($api); var_dump($test['response']['players'][0]['personaname']['steamid']); } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $data = file_get_contents($url); $data_output = json_decode($data, true); return $data_output; } So ea I've wrote a simple method to decode Json as I'll be doing a fair bit.. But just wondering the best way to print out arrays.. I can't for the life of me get it to print more than 1 element without it retunring an error e.g. Warning: Illegal string offset 'steamid' in /opt/lampp/htdocs/lan/lan-includes/scripts/class.steam.php on line 48 string(1) "R" So I can print one element, and if I add another it returns errors. EDIT -- Thanks for help, So this was my solution: function test_steamAPI() { $api = ('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key='.get_Steam_api().'&steamids=76561197960435530,76561197960435530'); $data = decode_url($api); foreach($data ['response']['players'] as $player) { echo "Steam id:" . $player['steamid'] . "\n"; echo "Community visibility :" . $player['communityvisibilitystate'] . "\n"; echo "Player profile" . $player['profileurl'] ."\n"; } } //Function to decode and return the data. function decode_url($url) { $decodeURL = $url; $json = file_get_contents($decodeURL); $data_output = json_decode($json, true); return $data_output; } Worked this out by taking a look at the data.. and a couple json examples, this returns an array based on the Steam API URL (It works for multiple queries.... just FYI) and you can insert loops inside for items etc.. (if anyone searches for this).
