• Variable number of GUI Buttons

  - by Wakaka

  I have a generic HTML5 Canvas GUI Button class and a Scene class. The Scene class has a method called createButton(), which will create a new Button with onclick parameter and store it in a list of buttons. I call createButton() for all UI buttons when initializing the Scene. Because buttons can appear and disappear very often during rendering, Scene would first deactivate all buttons (temporarily remove their onclick, onmouseover etc property) before each render frame. During rendering, the renderer would then activate the required buttons for that frame. The problem is that part of the UI requires a variable number of buttons, and their onclick, onmouseover etc properties change frequently. An example is a buffs system. The UI will list all buffs as square sprites for the current unit selected, and mousing over each square will bring up a tooltip with some information on the buff. But the number of buffs is variable thus I won't know how many buttons to create at the start. What's the best way to solve this problem? P.S. My game is in Javascript, and I know I can use HTML buttons, but would like to make my game purely Canvas-based. Create buttons on-the-fly during rendering. Thus I will only have buttons when I require them. After the render frame these buttons would be useless and removed. Create a fixed set of buttons that I'm going to assume the number of buffs per unit won't exceed. During each render frame activate the buttons accordingly and set their onmouseover property. Assign a button to each Buff instance. This sounds wrong as the buff button is a part of the GUI which can only have one unit selected. Assigning a button to every single Buff in the game seems to be overkill. Also, I would need to change the button's position every render frame since its order in the unit's list of buffs matter. Any other solutions? I'm actually quite for idea (1) but am worried about the memory/time issues of creating a new Button() object every render frame. But this is in Javascript where object creation is oh-so-common ({} mainly) due to automatic garbage collection. What is your take on this? Thanks!

• Input of mouseclick not always registered in XNA Update method

  - by LordrAider

  I have a problem that not all inputs of my mouse events seem to be registered. The update logic is checking a 2 dimensional array of 10x10 . It's logic for a jewel matching game. So when i switch my jewel I can't click on another jewel for like half a second. I tested it with a click counter variable and it doesn't hit the debugger when i click the second time after the jewel switch. Only if I do the second click after waiting half a second longer. Could it be that the update logic is too heavy that while he is executing update logic my click is happening and he doesn't register it? What am I not seeing here :)? Or doing wrong. It is my first game. My function of the update methode looks like this. public void UpdateBoard() { MouseState currentMouseState; currentMouseState = Mouse.GetState(); if (currentMouseState.LeftButton == ButtonState.Pressed && prevMouseState.LeftButton != ButtonState.Pressed) { UpdatingLogic = true; // this.CheckDropJewels(currentMouseState); //this.CheckMatches(3); //this.RemoveMatches(); this.CheckForSwitch(currentMouseState); this.MarkJewel(currentMouseState); UpdatingLogic = false; //reIndexMissingJewels = true; reIndexSwitchedJewels = true; } prevMouseState = currentMouseState; this.ReIndex(); this.UpdateJewels(); }

• Fastest approach to 3D animation

  - by HappyFerret

  I'm currently tasked with designing a small HTML5 game. Having done everything by myself so far (3D models, codebase, game design, etc) I'm now at a point where I'm running out of time. I've less than a day to animate and bind everything together. However, that's exactly my problem. I was under the naive impression that everything would be easier if I went with pre-rendered 3D models. However, I didn't consider the most difficult part. Animation. After having spent over an hour trying to figure out messiahStudio, I figured it's time to ask for outside help. Is there any easier solution to 3D animation than 3D rigging? What I'm basically looking for is some sort of tool that allows me to simply grab and move/deform select polygons. It doesn't have to be as life-like and accurate as rigging, just efficient enough. Were the circumstances any different, I might just learn how to rig. But that's sorely out of scope right now. PS:The models were created in Sculptris but are fairly low-poly.

• Open Source HTML/JS game(s) with license that would allow embedding in my app?

  - by DustMason

  I'm working on an educational app for kids. At the end of the sign-up process, the kids must wait for a confirmation from their parents in order to gain access to the app. While they wait for this to happen, we want to let the kid play a simple game as a way to keep their interest up. Is there a marketplace or repository for games with such a license that we could either purchase (affordably) or use for free in our own app?

• How do I add Different Screens to my C#/XNA Game?

  - by Ramses Brown

  I'm working on a Pong clone in XNA. Gameplay-wise, I have it where I want it to be. I want to add a title screen and some other screens to it like a menu, as well as a screen for the Winning/Losing results. I've tried the Game State Management Example on the App Hub site, but It's very complicated and I haven't been able to make sense of it. Is there a simpler way? I'm hoping for a solution that can be used in other projects too. Plus I'd like to know how to actually create menu items (basically, how do I display the different options on it, and highlight them, etc).

• which is better performance, using a disposable local variable or reusing a global one?

  - by petervaz

  This is for an android game. Suppose I have a function that is called several times for second and do some calculations involving an arraylist (or any other complex objects for what matter). Which approach would be preffered? local: private void doStuff(){ ArrayList<Type> XList = new ArrayList<Type>(); // do stuff with list } global: private ArrayList<Type> XList = new ArrayList<Type>(); private void doStuff(){ XList.clear(); // do stuff with list }

• Reasons to disable game save during combat (e.g. Mass Effect 2)

  - by Steve V.

  So I've been playing Mass Effect 2 (PC) and one of the things I've noticed is that you can only save your game when you're not engaged in combat. As soon as the first enemy shows up on your radar, the save button is disabled. Once combat is over, save functionality reappears. It seems reasonable to assume that Mass Effect 2 is a state machine, and therefore, the internal state of the program at any moment can be captured and reloaded later. This is basically a solved problem - games have been designed this way since the Half-Life era. It also seems reasonable to assume that BioWare knew what they were doing when they made the decision not to follow this model - it's a tried and true system; BioWare wouldn't have done it the way they did without some good reason. What reasons are there to disable game save functionality during combat?

• Restrict movement within a radius

  - by Phil

  I asked a similar question recently but now I think I know more about what I really want to know. I can answer my own question if I get to understand this bit. I have a situation where a sprite's center point needs to be constrained within a certain boundary in 2d space. The boundary is circular so the sprite is constrained within a radius. This radius is defined as a distance from the center of a certain point. I know the position of the center point and I can track the center position of the sprite. This is the code to detect the distance: float distance = Vector2.Distance(centerPosition, spritePosition)); if (distance > allowedDistance) { } The positions can be wherever on the grid, they are not described as in between -1 or 1. So basically the detecting code works, it only prints when the sprite is outside of it's boundary I just don't know what to do when it oversteps. Please explain any math used as I really want to understand what you're thinking to be able to elaborate on it myself.

• Why is my collision detection not accurate?

  - by optimisez

  After trying and trying, I still cannot understand why the leg of character exceeds the wall but no clipping issue when I hit the wall from below. How should I fix it to make him stand still on the wall? From collideWithBox() function below, it shows that playerDest.Y = boxDest.Y - boxDest.height; will get the position the character should standstill on the wall. Theoretically, the clipping effect won't be happen as the character hit the box from below works with the equation playerDest.Y = boxDest.Y + boxDest.height;. void collideWithBox() { if ( spriteCollide(playerDest, boxDest) && keyArr[VK_UP]) //playerDest.Y += 50; playerDest.Y = boxDest.Y + boxDest.height; else if ( spriteCollide(playerDest, boxDest) && !keyArr[VK_UP]) playerDest.Y = boxDest.Y - boxDest.height; } void initPlayer() { // Create texture. hr = D3DXCreateTextureFromFileEx(d3dDevice, "player.png", 169, 44, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255), NULL, NULL, &player); playerRect.left = playerRect.top = 0; playerRect.right = 29; playerRect.bottom = 36; playerDest.X = 0; playerDest.Y = 564; playerDest.length = playerRect.right - playerRect.left; playerDest.height = playerRect.bottom - playerRect.top; } void initBox() { hr = D3DXCreateTextureFromFileEx(d3dDevice, "brock.png", 330, 132, D3DX_DEFAULT, NULL, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, D3DCOLOR_XRGB(255, 255, 255), NULL, NULL, &box); boxRect.left = 33; boxRect.top = 0; boxRect.right = 63; boxRect.bottom = 30; boxDest.X = boxDest.Y = 300; boxDest.length = boxRect.right - boxRect.left; boxDest.height = boxRect.bottom - boxRect.top; } bool spriteCollide(Entity player, Entity target) { float left1, left2; float right1, right2; float top1, top2; float bottom1, bottom2; left1 = player.X; left2 = target.X; right1 = player.X + player.length; right2 = target.X + target.length; top1 = player.Y; top2 = target.Y; bottom1 = player.Y + player.height; bottom2 = target.Y + target.height; if (bottom1 < top2) return false; if (top1 > bottom2) return false; if (right1 < left2) return false; if (left1 > right2) return false; return true; }

• How to program a cutting tool for 3D model in game

  - by Jesse S

  I'm looking for a resource to figure out how to program a function to cut a 3d model in game. Example: Enemy/NPC is sliced into 2 pieces with a sword. His body is not hollow, you can see bloody texture where normally a 'polygon hole' would be. The first step is to actually 'cut/slice' the model, then add in polygons to fill the hole in the model. I know this can be done in 3D modelling software, but I'm not sure how to go about doing this in a game, code-wise. I do not wish to use 'pre cut-up" models, the code will determine where the cut is. Any pointers in the right direction would be greatly appreciated.

• Determining the angle to fire a shot when target and shooter moves, and bullet moves with shooter velocity added in

  - by Azaral

  I saw this question: Predicting enemy position in order to have an object lead its target and followed the link in the answer to stack overflow. In the stack overflow page I used the 2nd answer, the one that is a large mathematical derivation. My situation is a little different though. My first question though is will the answer provided in the stack overflow page even work to begin with, assuming the original circumstances of moving target and stationary shooter. My situation is a little different than that situation. My target moves, the shooter moves, and the bullets from the shooter start off with the velocities in x and y added to the bullets' x and y velocities. If you are sliding to the right, the bullets will remain in front of you as you move so as long as your velocity remains constant. What I'm trying to do is to get the enemy to be able to determine where they need to shoot in order to hit the player. Unless the player and enemy is stationary, the velocity from the ship adding to the velocity of the bullets will cause a miss. I'd rather like to prevent that. I used the formula in the stack overflow answer and did what I thought were the appropriate adjustments. I've been banging at this for the last four hours and I just can't make it click. It is probably something really simple and boneheaded that I am missing (that seems to be a lot of my problems lately). Here is the solution presented from the stack overflow answer: It boils down to solving a quadratic equation of the form: a * sqr(x) + b * x + c == 0 Note that by sqr I mean square, as opposed to square root. Use the following values: a := sqr(target.velocityX) + sqr(target.velocityY) - sqr(projectile_speed) b := 2 * (target.velocityX * (target.startX - cannon.X) + target.velocityY * (target.startY - cannon.Y)) c := sqr(target.startX - cannon.X) + sqr(target.startY - cannon.Y) Now we can look at the discriminant to determine if we have a possible solution. disc := sqr(b) - 4 * a * c If the discriminant is less than 0, forget about hitting your target -- your projectile can never get there in time. Otherwise, look at two candidate solutions: t1 := (-b + sqrt(disc)) / (2 * a) t2 := (-b - sqrt(disc)) / (2 * a) Note that if disc == 0 then t1 and t2 are equal. If there are no other considerations such as intervening obstacles, simply choose the smaller positive value. (Negative t values would require firing backward in time to use!) Substitute the chosen t value back into the target's position equations to get the coordinates of the leading point you should be aiming at: aim.X := t * target.velocityX + target.startX aim.Y := t * target.velocityY + target.startY Here is my code, after being corrected by Sam Hocevar (thank you again for your help!). It still doesn't work. For some reason it never enters the section of code inside the if(disc = 0) (obviously because it is always less than zero but...). However, if I plug the numbers from my game log on the enemy and player positions and velocities it outputs a valid firing solution. I have looked at the code side by side a couple of times now and I can't find any differences. There has got to be something simple I'm missing here. If someone else could look at this code and determine what is going on here I'd appreciate it. I know it's not going through that section because if it were, shouldShoot would become true and the enemy would be blasting away at the player. This section calls the function in question, CalculateShootHeading() if(shouldMove) { UseEngines(); } x += xVelocity; y += yVelocity; CalculateShootHeading(); if(shouldShoot) { ShootWeapons(); } UpdateWeapons(); This is CalculateShootHeading(). This is inside the enemy class so x and y are the enemy's x and y and the same with velocity. One output from my game log gives Player X = 2108, Player Y = -180.956, Player X velocity = 10.9949, Player Y Velocity = -6.26017, Enemy X = 1988.31, Enemy Y = -339.051, Enemy X velocity = 1.81666, Enemy Y velocity = -9.67762, 0 enemy projectiles. The output from the console tester is Bullet position = 2210.49, -239.313 and Player Position = 2210.49, -239.313. This doesn't make any sense. The only thing that could be different is the code or the input into my function in the game and I've checked that and I don't think that it is wrong as it's updated before this and never changed. float const bulletSpeed = 30.f; float const dx = playerX - x; float const dy = playerY - y; float const vx = playerXVelocity - xVelocity; float const vy = playerYVelocity - yVelocity; float const a = vx * vx + vy * vy - bulletSpeed * bulletSpeed; float const b = 2.f * (vx * dx + vy * dy); float const c = dx * dx + dy * dy; float const disc = b * b - 4.f * a * c; shouldShoot = false; if (disc >= 0.f) { float t0 = (-b - std::sqrt(disc)) / (2.f * a); float t1 = (-b + std::sqrt(disc)) / (2.f * a); if (t0 < 0.f || (t1 < t0 && t1 >= 0.f)) { t0 = t1; } if (t0 >= 0.f) { float shootx = vx + dx / t0; float shooty = vy + dy / t0; heading = std::atan2(shooty, shootx) * RAD2DEGREE; } shouldShoot = true; }

• Drawing application on OpenGL for iOS (iPad)

  - by Alesia

  Some help is needed. I'm developing drawing application on OpenGL (deployment target 4.0) for iOS (iPad). We have 3 drawing tools: pen, marker (with alfa) and eraser. I draw with textures, using blending in orthographic projection. I can't use z-ordering because in this case I have to face a lot of troubles with cutting and erasing. The thing that I need is to make the pen be always on the top. When I first use marker and than pen - it's ok. But if I use pen first and marker over the pen - I can't see pen color under marker. I'd appreciate any help or advice. Thank you veeeeeery much!

• XNA content.load Dependancy

  - by Richard

  Quick question, My project i'm building for test purposes is working fine but i have dependencies flying around everywhere due to the XNA framework. In Update i have gametime passed everywhere... this is okay. In Draw i have gametime & spritebatch passed everywhere... this is okay. My issue is in the content.load textures/sounds/fonts. I have them as public variables ie Texture1 = Content.load(of texture2d)("Texture1") I'm passing a 'Game1' pointer into the constructor of every new class being instantiated to gain access to these variables. Am i missing an OOP trick to prevent me having to pass a pointer to 'game1' to every New class?

• Blender: Having trouble moving vertices

  - by capcom

  I've been using Blender for two days now, and ran into an issue while following a tutorial. Before anything else, I'd like to show you all what my problem precisely is. Here is a short video I uploaded: click here. I thought it may be easier for you all to help me identify and solve my problem more accurately with a visual aid. I would like to emphasize that this issue began to occur after I extruded that trapezoidal region (misstated as a parallelogram in the video). I decided that I did not want the extruded region, and just hit undo. Ever since then, I began to experience the problem you viewed. Thanks.

• Can minecraft support an asymmetrical mesh?

  - by Qwaar

  So in a bout of fancy I have decided I want to play as a Zaku II from gundam, and was saddened that player skins must be symmetrical. Then I remembered my friends mod that let him play as a MLP pony, and another one that let you shapeshift into mobs. So I decided I could just butcher a player model mesh and slap on the shoulder spike and shield, slap a Zaku skin I found on it, port the colors over onto more texture for the shoulder portions, and call it a day once I added it to the shiftable list, before butchering a gun mod to turn a gun into a ZMP-78. Before I get started on this though, I need to know if minecraft will support an asymmetrical mesh.

• android multitouch problem

  - by Max

  Im aware that there a a couple of posts on this matter, but Ive tried all of them and none of them gets rid of my problem. Im starting to get close to the end of my game so I bought a cabel to try it on a real phone, and as I expected my multitouch dosnt work. I use 2 joysticks, one to move my character and one to change his direction so he can shoot while walking backwards etc. my local variable: public void update(MotionEvent event) { if (event == null && lastEvent == null) { return; } else if (event == null && lastEvent != null) { event = lastEvent; } else { lastEvent = event; } int index = event.getActionIndex(); int pointerId = event.getPointerId(index); statement for left Joystick: if (pointerId == 0 && event.getAction() == MotionEvent.ACTION_DOWN && (int) event.getX() > steeringxMesh - 50 && (int) event.getX() < steeringxMesh + 50 && (int) event.getY() > yMesh - 50 && (int) event.getY() < yMesh + 50) { dragging = true; } else if (event.getAction() == MotionEvent.ACTION_UP) { dragging = false; } if (dragging) { //code for moving my character statement for my right joystick: if (pointerId == 1 && event.getAction() == MotionEvent.ACTION_DOWN && (int) event.getX() > shootingxMesh - 50 && (int) event.getX() < shootingxMesh + 50 && (int) event.getY() > yMesh - 50 && (int) event.getY() < yMesh + 50) { shooting = true; } else if (event.getAction() == MotionEvent.ACTION_UP) { shooting = false; } if (shooting) { // code for aiming } This class is my main-Views onTouchListener and is called in a update-method that gets called in my game-loop, so its called every frame. Im really at a loss here, I've done a couple of tutorials and Ive tried all relevant solutions to similar posts. Can post entire Class if necessary but I think this is all the relevant code. Just hope someone can make some sence out of this.

• How to debug Android App Eclipse?

  - by user2534694

  Ok. So while this isnt a programming question. I wanted to know how do people debug apps? How do you view log cat, and where these exceptions are thrown etc? And do I need to run the app on the emulator to see all the stuff, or is there a way to view this after running the app on my phone(while not being connected to the computer) Links to plugins and tips would be really helpful, as im gonna start work on my next game, and while the first one works fine, had a lot of problems while debugging.

• How can I keep track of a battle log on a web game?

  - by Jay W

  Recently I started working on a Web turn-based PvP RPG game. Now I'm working on the battle system but I encountered some issues: How can I keep track of everything that happens in the battle? It should keep track of the characters on the field, inventory, the damage done etc. I first thought I would simply put it in the (MySQL) database, but I think it will be too much. Especially if several people are in a battle. I thought of puting this in sessions or cookies but I don't think thats reliable. Does anyone have an idea how I can do this?

• How to load data for specific level at runtime?

  - by Siddharth

  I'm trying to create a game with many levels loaded from XML files. In my game I have many objects in each level. At present my game contains 20 levels, and I load all the textures at once on startup. But I think the correct way to do it is to only load textures used in the current level. I don't know how to do that. So please explain this by providing some example code. At present I create a class for each type of entity by extending my Sprite class. This subclass loads the appropriate image. I know this is not the best way to do things. Basically I want to know how to load large levels efficiently in Andengine. What is the proper method for loading textures, level data and background images from files when the level is run?

• 2D Tile Collision free movement

  - by andrepcg

  I'm coding a 3D game for a project using OpenGL and I'm trying to do tile collision on a surface. The surface plane is split into a grid of 64x64 pixels and I can simply check if the (x,y) tile is empty or not. Besides having a grid for collision, there's still free movement inside a tile. For each entity, in the end of the update function I simply increase the position by the velocity: pos.x += v.x; pos.y += v.y; I already have a collision grid created but my collide function is not great, i'm not sure how to handle it. I can check if the collision occurs but the way I handle is terrible. int leftTile = repelBox.x / grid->cellSize; int topTile = repelBox.y / grid->cellSize; int rightTile = (repelBox.x + repelBox.w) / grid->cellSize; int bottomTile = (repelBox.y + repelBox.h) / grid->cellSize; for (int y = topTile; y <= bottomTile; ++y) { for (int x = leftTile; x <= rightTile; ++x) { if (grid->getCell(x, y) == BLOCKED){ Rect colBox = grid->getCellRectXY(x, y); Rect xAxis = Rect(pos.x - 20 / 2.0f, pos.y - 20 / 4.0f, 20, 10); Rect yAxis = Rect(pos.x - 20 / 4.0f, pos.y - 20 / 2.0f, 10, 20); if (colBox.Intersects(xAxis)) v.x *= -1; if (colBox.Intersects(yAxis)) v.y *= -1; } } } If instead of reversing the direction I set it to false then when the entity tries to get away from the wall it's still intersecting the tile and gets stuck on that position. EDIT: I've worked with Flashpunk and it has a great function for movement and collision called moveBy. Are there any simplified implementations out there so I can check them out?

• How do I use Content.Load() with raw XML files?

  - by xnanewb

  I'm using the Content.Load() mechanism to load core game definitions from XML files. It works fine, though some definitions should be editable/moddable by the players. Since the content pipeline compiles everything into xnb files, that doesn't work for now. I've seen that the inbuild XNA Song content processor does create 2 files. 1 xnb file which contains meta data for the song and 1 wma file which contains the actual data. I've tried to rebuild that mechanism (so that the second file is the actual xml file), but for some reason I can't use the namespace which contains the IntermediateSerializer class to load the xml (obviously the namespace is only available in a content project?). How can I deploy raw, editable xml files and load them with Content.Load()?

• MMO Web game mouse vs wasd

  - by LazyProgrammer

  If considering to develop a web browser based game with multiple people and it's an RPG, click to move would probably be the only choice in movement right? Because if you were to use WASD and then ajax to the server every second that a player held on to the WASD key, that'd be pretty resource intensive if the server had to calculate the position and return the map image, assuming the next few screens are already buffered right? or is there a way to implement a WASD style and still have server side do all the calculations. (server side calculations to avoid cheating)

• Getting 2D Platformer entity collision Response Correct (side-to-side + jumping/landing on heads)

  - by jbrennan

  I've been working on a 2D (tile based) 2D platformer for iOS and I've got basic entity collision detection working, but there's just something not right about it and I can't quite figure out how to solve it. There are 2 forms of collision between player entities as I can tell, either the two players (human controlled) are hitting each other side-to-side (i. e. pushing against one another), or one player has jumped on the head of the other player (naturally, if I wanted to expand this to player vs enemy, the effects would be different, but the types of collisions would be identical, just the reaction should be a little different). In my code I believe I've got the side-to-side code working: If two entities press against one another, then they are both moved back on either side of the intersection rectangle so that they are just pushing on each other. I also have the "landed on the other player's head" part working. The real problem is, if the two players are currently pushing up against each other, and one player jumps, then at one point as they're jumping, the height-difference threshold that counts as a "land on head" is passed and then it registers as a jump. As a life-long player of 2D Mario Bros style games, this feels incorrect to me, but I can't quite figure out how to solve it. My code: (it's really Objective-C but I've put it in pseudo C-style code just to be simpler for non ObjC readers) void checkCollisions() { // For each entity in the scene, compare it with all other entities (but not with one it's already compared against) for (int i = 0; i < _allGameObjects.count(); i++) { // GameObject is an Entity GEGameObject *firstGameObject = _allGameObjects.objectAtIndex(i); // Don't check against yourself or any previous entity for (int j = i+1; j < _allGameObjects.count(); j++) { GEGameObject *secondGameObject = _allGameObjects.objectAtIndex(j); // Get the collision bounds for both entities, then see if they intersect // CGRect is a C-struct with an origin Point (x, y) and a Size (w, h) CGRect firstRect = firstGameObject.collisionBounds(); CGRect secondRect = secondGameObject.collisionBounds(); // Collision of any sort if (CGRectIntersectsRect(firstRect, secondRect)) { //////////////////////////////// // // // Check for jumping first (???) // // //////////////////////////////// if (firstRect.origin.y > (secondRect.origin.y + (secondRect.size.height * 0.7))) { // the top entity could be pretty far down/in to the bottom entity.... firstGameObject.didLandOnEntity(secondGameObject); } else if (secondRect.origin.y > (firstRect.origin.y + (firstRect.size.height * 0.7))) { // second entity was actually on top.... secondGameObject.didLandOnEntity.(firstGameObject); } else if (firstRect.origin.x > secondRect.origin.x && firstRect.origin.x < (secondRect.origin.x + secondRect.size.width)) { // Hit from the RIGHT CGRect intersection = CGRectIntersection(firstRect, secondRect); // The NUDGE just offsets either object back to the left or right // After the nudging, they are exactly pressing against each other with no intersection firstGameObject.nudgeToRightOfIntersection(intersection); secondGameObject.nudgeToLeftOfIntersection(intersection); } else if ((firstRect.origin.x + firstRect.size.width) > secondRect.origin.x) { // hit from the LEFT CGRect intersection = CGRectIntersection(firstRect, secondRect); secondGameObject.nudgeToRightOfIntersection(intersection); firstGameObject.nudgeToLeftOfIntersection(intersection); } } } } } I think my collision detection code is pretty close, but obviously I'm doing something a little wrong. I really think it's to do with the way my jumps are checked (I wanted to make sure that a jump could happen from an angle (instead of if the falling player had been at a right angle to the player below). Can someone please help me here? I haven't been able to find many resources on how to do this properly (and thinking like a game developer is new for me). Thanks in advance!

• Prediction happening on (sending) client side

  - by Daniel

  This seems like a simple enough concept, but I haven't seen this implemented anywhere yet. Assuming that the server just forwards and verifies data... I'm using mouse-based movement, so it's not too difficult to predict the location of the player 150ms from when the event is sent. I'm thinking it is more accurate than using old data and older data on the receiving clients' side. The question I have, is why can I not find any examples of this? Is there something fundamentally wrong with this that I cannot find anyone implementing or talking about implementing this.

• What are the advantages to use vector-based fonts over bitmap fonts in (2d) games?

  - by jmp97

  I know that many games are using bitmap fonts. Which are the advantages for vector-based font rendering / manipulation when compared to bitmap fonts and in which scenarios would they matter the most? Prefer a focus on 2d games when answering this question. If relevant, please include examples for games using either approach. Some factors you might consider: amount of text used in the game scaling of text overlaying glyphs and anti-aliasing general rendering quality font colors and styling user interface requirements localisation / unicode text wrapping and formatting cross-platform deployment 2d vs 3d Background: I am developing a simple falling blocks game in 2d, targeted for pc. I would like to add text labels for level, score, and menu buttons. I am using SFML which uses FreeType internally, so vector-based features are easily available for my project. In my view, font sizes in simple games often don't vary, and bitmap fonts should be easier for cross-platform concerns (font-formats and font rendering quality). But I am unsure if I am missing some important points here, especially since I want to polish the looks of the final game.
