• Regulating how much to draw based on how much was drawn last frame.

  - by Mike Howard

  I have a 3D game world on an iPhone (limited graphics speed), and I'm already regulating whether I draw each shape on the screen based on it's size and distance from the camera. Something like... if (how_big_it_looks_from_the_camera > constant) then draw What I want to do now is also take into account how many shapes are being drawn, so that in busier areas of the game world I can draw less than I otherwise would. I tried to do this by dividing how_big_it_looks by the number of shapes that were drawn last frame (well, the square root of this but I'm simplifying - the problem is the same). if (how_big_it_looks / shapes_drawn > constant2) then draw But the check happens at the level of objects which represent many drawn shapes, and if an object containing many shapes is switched on, it increases shapes_drawn lots and switches itself back off the next frame. It flickers on and off. I tried keeping a kind of weighted average of previous values, by each frame doing something like shapes_drawn_recently = 0.9 * shapes_drawn_recently + 0.1 * shapes_just_drawn, but of course it only slows the flickering down because of the nature of the feedback loop. Is there a good way of solving this? My project is in Objective-C, but a general algorithm or pseudo-code is good too. Thanks.

• RPG Monster-Area, Spawn, Loot table Design

  - by daemonfire300

  I currently struggle with creating the database structure for my RPG. I got so far: tables: area (id) monster (id, area.id, monster.id, hp, attack, defense, name) item (id, some other values) loot (id = monster.id, item = item.id, chance) spawn (id = area.id, monster = monster.id, count) It is a browser-based game like e.g. Castle Age. The player can move from area to area. If a player enters an area the system spawns, based on the area.id and using the spawn table data, new monsters into the monster table. If a player kills a monster, the system picks the monster.id looks up the items via the the loot table and adds those items to the player's inventory. First, is this smart? Second, I need some kind of "monster_instance"-table and "area_instance"-table, since each player enters his very own "area" and does damage to his very own "monsters". Another approach would be adding the / a player.id to the monster table, so each monster spawned, has it's own "player", but I still need to assign them to an area, and I think this would overload the monster table if I put in the player.id and the area.id into the monster table. What are your thoughts? Temporary Solution monster (id, attackDamage, defense, hp, exp, etc.) monster_instance (id, player.id, area_instance.id, hp, attackDamage, defense, monster.id, etc.) area (id, name, area.id access, restriction) area_instance (id, area.id, last_visited) spawn (id, area.id, monster.id) loot (id, monster.id, chance, amount, ?area.id?) An example system-flow would be: Player enters area 1: system creates area_instance of type area.id = 1 and sets player.location to area.id = 1 If Player wants to battle monsters in the current area: system fetches all spawn entries matching area.id == player.location and creates a new monster_instance for each spawn by fetching the according monster-base data from table monster. If a monster is fetched more than once it may be cached. If Player actually attacks a monster: system updates the according monster_instance, if monster dies the instance if removed after creating the loot If Player leaves the area: area_instance.last_visited is set to NOW(), if player doesn't return to data area within a certain amount of time area_instance including all its monster_instances are deleted.

• Everything turning black when pitching down

  - by Gordon

  Just a quick questions about something that's occurring in my world. Every time I pitch my camera downward, everything starts turning black, and if I pitch upward, everything sort of intensifies. I'm multiplying my normals by the normal matrix in the shader, and I'm multiplying my lights direction by the model view matrix. If I leave the normal and light dir in world space everything ends up fine. I thought putting them both in view space would not cause those weird things to happen?

• 3D Paint tool in Maya

  - by Joris

  Hey everyone, could someone help me out on this question? When I am trying to texture objects in maya (for example a barrel) I want to texture it with a brush. When I try to use the 3D painting tool it al gets black even when I have a image file selected. Also the resolution is very very low of the models and textures in maya, though the texture image is very high quality. Can someone please help me? Thanks so much for helping.

• How can i get latency when using Game Center?

  - by Freddy

  I'm pretty new to network programming. Basically I'm using game center for making a relatively simple iPhone game using Game-center p2p. However i'm now working on a algorithm to improve the multiplayer performance. But, I need to know how long it took for a package to travel from one device to the another device (latency) for the algorithm to work good. As for now, I have solved the problem by sending a double with time interval since 1970 in the package and then I compare it with the time at the other device. However I have heard that the NSDate methods is connected to the internet, which also will cause latency so the time interval would not be perfectly correct. What is the ideal way to check for how long it take for a package to be sent?

• Converting a GameObject method call from UnityScript to C#

  Here is the UnityScript implementation of the method i use to generate a randomly tiled background, the problem i'm having relates to how to translate the call to the newTile method in c#, so far i've had no luck fiddling... can anyone point me in the correct direction?

• Play audio in javascript with a good performance

  - by João

  I'm developing a browser game where the player can shoot. Everytime he shoots it play a sound. Currently i'm using this code to play sounds in JavaScript: var audio = document.createElement("audio"); audio.src = "my_sound.mp3"; audio.play(); I'm worried about performance here. Will 10 simultaneous sounds impact my game performance too much? Will all audio objects stay in memory even after they are played?

• Error in my Separating Axis Theorem collision code

  - by Holly

  The only collision experience i've had was with simple rectangles, i wanted to find something that would allow me to define polygonal areas for collision and have been trying to make sense of SAT using these two links Though i'm a bit iffy with the math for the most part i feel like i understand the theory! Except my implementation somewhere down the line must be off as: (excuse the hideous font) As mentioned above i have defined a CollisionPolygon class where most of my theory is implemented and then have a helper class called Vect which was meant to be for Vectors but has also been used to contain a vertex given that both just have two float values. I've tried stepping through the function and inspecting the values to solve things but given so many axes and vectors and new math to work out as i go i'm struggling to find the erroneous calculation(s) and would really appreciate any help.

• Displaying possible movement tiles

  - by Ash Blue

  What's the fastest way to highlight all possible movement tiles for a player on a square grid? Players can only move up, down, left, right. Tiles can cost more than one movement, multiple levels are available to move, and players can be larger than one tile. Think of games like Fire Emblem, Front Mission, and XCOM. My first thought was to recursively search for connecting tiles. This quickly demonstrated many shortcomings when blockers, movement costs, and other features were added into the mix. My second thought was to use an A* pathfinding algorithm to check all tiles presumed valid. Presumed valid tiles would come from an algorithm that generates a diamond of tiles from the player's speed (see example here http://jsfiddle.net/truefreestyle/Suww8/9/). Problem is this seems a little slow and expensive. Is there a faster way? Edit: In Lua for Corona SDK, I integrated the following movement generation controller. I've linked to a Gist here because the solution is around 90 lines of code. https://gist.github.com/ashblue/5546009

• Vertical Scrolling In Tile Based XNA Platformer

  - by alec100_94

  I'm making a 2D platformer in XNA 4.0. I have created a working tile engine, which works well for my purposes, and Horizontal Scrolling works flawlessly, however I am having great trouble with Vertical scrolling. I Basically want the camera to scroll up (world to scroll down) when the player reaches a certain Y co-ordinate, and I would also like to automatically scroll back down if coming down, and that co-ordinate is passed. My biggest problem is I have no real way of detecting the direction the player is moving in using only the Y Co-ord. Here Is My Code Code For The Camera Class (which appears to be a very different approach to most camera classes I have seen). using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; namespace Marvin { class Camera : TileEngine { public static bool startReached; public static bool endReached; public static void MoveRight(float speed = 2) { //Moves The Position of Each Tile Right foreach (Tile t in tiles) { if(t!=null) { t.position.X -= speed; } } } public static void MoveLeft(float speed = 2) { //Moves The Position of Each Tile Right foreach (Tile t in tiles) { if(t!=null) { t.position.X += speed; } } } public static void MoveUp(float speed = 2) { foreach (Tile t in tiles) { if(t!=null) { t.position.Y += speed; } } } public static void MoveDown(float speed = 2) { foreach (Tile t in tiles) { if(t!=null) { t.position.Y -= speed; } } } public static void Restrain() { if(tiles.Last().position.X<Main.graphics.PreferredBackBufferWidth-tiles.Last().size.X) { MoveLeft(); endReached = true; } else { endReached = false; } if(tiles[1].position.X>0) { MoveRight(); startReached = true;} else { startReached = false; } } } } Here is My Player Code for Left and Right Scrolling/Moving if (Main.currentKeyState.IsKeyDown(Keys.Right)) { Camera.MoveRight(); if(Camera.endReached) { MoveRight(2); } else { if(marvin.GetRectangle().X!=Main.graphics.PreferredBackBufferWidth-(marvin.GetRectangle().X+marvin.GetRectangle().Width)) { MoveRight(2); Camera.MoveLeft(); } } } if(Main.currentKeyState.IsKeyDown(Keys.Left)) { Camera.MoveLeft(); if(Camera.startReached) { MoveLeft(2); } else { if(marvin.GetRectangle().X!=Main.graphics.PreferredBackBufferWidth-(marvin.GetRectangle().X+marvin.GetRectangle().Width)) { MoveLeft(2); Camera.MoveRight(); } } } Camera.Restrain(); if(marvin.GetRectangle().X>Main.graphics.PreferredBackBufferWidth-marvin.GetRectangle().Width) { MoveLeft(2); } if(marvin.GetRectangle().X<0) { MoveRight(2); } And Here Is My Player Jumping/Falling Code which may cause some conflicts with the vertical camera movement. if (!jumping) { if(!TileEngine.TopOfTileCollidingWith(footBounds)) { MoveDown(5); } else { if(marvin.GetRectangle().Y != TileEngine.LastPlatformStoodOnTop()-marvin.GetRectangle().Height) { float difference = (TileEngine.LastPlatformStoodOnTop()-marvin.GetRectangle().Height) - (marvin.GetRectangle().Y); marvin.SetRectangle(marvin.GetRectangle().X,(int)(marvin.GetRectangle().Y+difference)); armR.SetRectangle(armR.GetRectangle().X,(int)(armR.GetRectangle().Y+difference)); armL.SetRectangle(armL.GetRectangle().X,(int)(armL.GetRectangle().Y+difference)); eyeL.SetRectangle(eyeL.GetRectangle().X,(int)(eyeL.GetRectangle().Y+difference)); eyeR.SetRectangle(eyeR.GetRectangle().X,(int)(eyeR.GetRectangle().Y+difference)); } } } if (Main.currentKeyState.IsKeyDown(Keys.Up) && Main.previousKeyState.IsKeyUp(Keys.Up) && TileEngine.TopOfTileCollidingWith(footBounds)) { jumping = true; } if(jumping) { if(TileEngine.LastPlatformStoodOnTop()>0 && (TileEngine.LastPlatformStoodOnTop() - footBounds.Bottom)<120) { MoveUp(5); } else { jumping = false; } } All player code I have tried for vertical movements has failed, or caused weird results (like falling through platforms), and most have been a variation on the method I described above, hence I have not included it. I would really appreciate some help implementing a simple vertical scrolling into this game, Thanks.

• Android Loading Screen: How do I use a stack to load elements?

  - by tom_mai78101

  I have some problems with figuring out what value I should put in the function: int value_needed_to_figure_out = X; ProgressBar.incrementProgressBy(value_needed_to_figure_out); I've been researching about loading screens and how to use them. Some examples I've seen have implemented Thread.sleep() in a Handler.post(new Runnable()) function. To me, I got most of that concept of using the Handler to update the ProgressBar, while pretending to do some heavy crunching work. So, I kept looking. I have read this thread here: How do I load chunks of data from an assest manager during a loading screen? It said that I can try using a stack it needs to load, and adding a size counter as I add elements to the stack. What does it mean? This is the part where I'm totally stumped. If anyone would provide some hints, I'll gladly appreciate it. Thanks in advance.

• How to design a leaderboard?

  - by PeterK

  This sounds like an easy thing but when i considering the following Many players Some have played many games and some just started Different type of statistics ...on what information should the actual ranking be based on. I am planning to display the board in a UITableView so there is limited space available per player. However, I am not bound to the UITableView if there is a better solution. This is a quiz game and the information i am currently capturing per player is: #games played totally #games played per game type (current version have only one game type) #questions answered #correct answers Maybe i should include additional information. I have been thinking about having a leaderboard property page where the player can decide on what basis the leaderboard should display information but would like to avoid the complexity in that. However, if that is needed i will do it. Anyone that can give me some advice on how to design the presentation of this would be highly appreciated?

• Making large scale changes to an economy in a social game

  - by Zach

  Are there any examples or case studies of social games, specifically on Facebook, where the developer has made drastic changes to the economy? I'm specifically interested in examples where the old economy was based off of purchasing items with Facebook credits then moving to a new model where the same inventory or similar inventory is sold with a soft currency. The closest comparisons I've been able to find so far are looking at iOS games that have gone from purchase models to freemium models, but haven't found a comparable scenario in a social game besides larger scale MMO's.

• Newton Game Dynamics: Making an object not affect another object

  - by Boreal

  I'm going to be using Newton in my networked action game with Mogre. There will be two "types" of physics object: global and local. Global objects will be kept in sync for everybody; these include the players, projectiles, and other gameplay-related objects. Local objects are purely for effect, like ragdolls, debris, and particles. Is there a way to make the global objects affect the local objects without actually getting affected themselves? I'd like debris to bounce off of a tank, but I don't want the tank to respond in any way.

• Object detection in bitmap JavaScript canvas

  I want to detect clicks on canvas elements which are drawn using paths. So far I have stored element paths in a JavaScript data structure and then check the coordinates of hits which match the element's coordinates. Rendering each element path and checking the hits would be inefficient when there are a lot of elements. I believe there must be an algorithm for this kind of coordinate search, can anyone help me with this?

• Collision detection code style

  - by Marian Ivanov

  Not only there are two useful broad-phase algorithms and a lot of useful narrowphase algorithms, there are also multiple code styles. Arrays vs. calling Make an array of broadphase checks, then filter them with narrowphase checks, then resolve them. function resolveCollisions(thingyStructure * a,thingyStructure * b,int index){ possibleCollisions = getPossibleCollisions(b,a->get(index)); for(i=0; i<possibleCollitionsNumber; i++){ if(narrowphase(possibleCollisions[i],a[index])) { collisions->push(possibleCollisions[i]); }; }; for(i=0; i<collitionsNumber; i++){ //CODE FOR RESOLUTION }; }; Make the broadphase call the narrowphase, and the narrowphase call the resolution function resolveCollisions(thingyStructure * a,thingyStructure * b,int index){ broadphase(b,a->get(index)); }; function broadphase(thingy * with, thingy * what){ while(blah){ //blahcode narrowphase(what,collidingThing); }; }; Events vs. in-the-loop Fire an event. This abstracts the check away, but it's trickier to make an equal interaction. a[index] -> collisionEvent(eventdata); //much later int collisionEvent(eventdata){ //resolution gets here } Resolve the collision inside the loop. This glues narrowphase and resolution into one layer. if(narrowphase(possibleCollisions[i],a[index])) { //CODE GOES HERE }; The questions are: Which of the first two is better, and how am I supposed to make a zero-sum Newtonian interaction under B1.

• Novice prototyping a massive multiplayer webpage based gaming system

  - by Sean Hendlin

  I'm trying to build a website based game in which various pages of the site act as different areas of the game. I am wondering what you would recommended as a design structure. Which languages would be best if building what will hopefully becomes a massive system able to scale to massive amounts of users. I am wondering if and how various elements from differing languages could be meshed to interact with each other. For example could I use html5, javascript, and PHP? What about asp.net how might that factor in? I'm a newbie programmer but I've been working on this idea for years and I want to build it to reality. Your comments and suggestions are appreciated. P.S.: The game is not all graphics and animation (though flash like appearance and some animation would be nice). What I am thinking of is essentially a heavily gamified system of forms. And LOTS of data in many different categories cross referencing each-other. I'm not sure how to go about structuring the collection of data. Also while I know javascript can be used to process some functions, I'm wondering what sort of base system I would need to handle the server side processing of what I am expecting to be some pretty significant algorithm processing. That is to say I expect to have many many many functions and I'm not sure how to mange this using javascript. I feel like they would be forgotten, mixed up, disorganizes as they essentially only exist where they are coded. I guess I need to learn something of libraries? OK, Thank you! Is enough from me for now.

• Get Specific depth values in Kinect (XNA)

  - by N0xus

  I'm currently trying to make a hand / finger tracking with a kinect in XNA. For this, I need to be able to specify the depth range I want my program to render. I've looked about, and I cannot see how this is done. As far as I can tell, kinect's depth values only work with pre-set ranged found in the depthStream. What I would like to do is make it modular so that I can change the depth range my kinect renders. I know this has been down before but I can't find anything online that can show me how to do this. Could someone please help me out? I have made it possible to render the standard depth view with the kinect, and the method that I have made for converting the depth frame is as follows (I've a feeling its something in here I need to set) private byte[] ConvertDepthFrame(short[] depthFrame, DepthImageStream depthStream, int depthFrame32Length) { int tooNearDepth = depthStream.TooNearDepth; int tooFarDepth = depthStream.TooFarDepth; int unknownDepth = depthStream.UnknownDepth; byte[] depthFrame32 = new byte[depthFrame32Length]; for (int i16 = 0, i32 = 0; i16 < depthFrame.Length && i32 < depthFrame32.Length; i16++, i32 += 4) { int player = depthFrame[i16] & DepthImageFrame.PlayerIndexBitmask; int realDepth = depthFrame[i16] >> DepthImageFrame.PlayerIndexBitmaskWidth; // transform 13-bit depth information into an 8-bit intensity appropriate // for display (we disregard information in most significant bit) byte intensity = (byte)(~(realDepth >> 8)); if (player == 0 && realDepth == 00) { // white depthFrame32[i32 + RedIndex] = 255; depthFrame32[i32 + GreenIndex] = 255; depthFrame32[i32 + BlueIndex] = 255; } // omitted other if statements. Simple changed the color of the pixels if they went out of the pre=set depth values else { // tint the intensity by dividing by per-player values depthFrame32[i32 + RedIndex] = (byte)(intensity >> IntensityShiftByPlayerR[player]); depthFrame32[i32 + GreenIndex] = (byte)(intensity >> IntensityShiftByPlayerG[player]); depthFrame32[i32 + BlueIndex] = (byte)(intensity >> IntensityShiftByPlayerB[player]); } } return depthFrame32; } I have a strong hunch it's something I need to change in the int player and int realDepth values, but i can't be sure.

• How can I transform a Point2f with a matrix on Android?

  - by Vivendi

  I'm developing for Android and I'm using the android.renderscript.Matrix3f class to do some calculations. What I need to do now is to now is to do something like mat.tranform(pointIn, pointOut); So I need to transform a matrix by a given Point class. In awt I would simply do this: AffineTransform t = new AffineTransform(); Point2D.Float p = new Point2D.Float(); t.transform( p, p ); But in Android I now have this: Matrix3f t = new Matrix3f(); PointF p = new PointF(); // Now I need to tranform it somehow.. But the Matrix3f class in Android doesn't have a Matrix.transform(Point2D ptSrc, Point2D ptDst) method. So I guess I have to do the transformation manually. But I'm not really sure how that works. From what I've seen it's something like a translate and then a rotate? Could anyone please tell me how to do this in code?

They know this type of projects don't last long because of the copyrighted material used, but they somehow made their client extract resources from ROMS. So they don't offer any copyrighted material on their download. I wonder what technique they could be using for this? All I know is that they use LWJGL.

• OpenGL ES 2.0 example for JOGL

  - by fjdutoit

  I've scoured the internet for the last few hours looking for an example of how to run even the most basic OpenGL ES 2 example using JOGL but "by Jupiter!" it has been a total fail. I tried converting the android example from the OpenGL ES 2.0 Programming Guide examples (and at the same time looking at the WebGL example -- which worked fine) yet without any success. Are there any examples out there? If anyone else wants some extra help regarding this question see this thread on the official Jogamp forum.

• Automatically zoom out the camera to show all players

  - by user36159

  I am building a game in XNA that takes place in a rectangular arena. The game is multiplayer and each player may go where they like within the arena. The camera is a perspective camera that looks directly downwards. The camera should be automatically repositioned based on the game state. Currently, the xy position is a weighted sum of the xy positions of important entities. I would like the camera's z position to be calculated from the xy coordinates so that it zooms out to the point where all important entities are visible. My current approach is to: hw = the greatest x distance from the camera to an important entity hh = the greatest y distance from the camera to an important entity Calculate z = max(hw / tan(FoVx), hh / tan(FoVy)) My code seems to almost work as it should, but the resulting z values are always too low by a factor of about 4. Any ideas?

• DX11 - Weird shader behavior with and without branching

  - by Martin Perry

  I have found problem in my shader code, which I dont´t know how to solve. I want to rewrite this code without "ifs" tmp = evaluate and result is 0 or 1 (nothing else) if (tmp == 1) val = X1; if (tmp == 0) val = X2; I rewite it this way, but this piece of code doesn ´t word correctly tmp = evaluate and result is 0 or 1 (nothing else) val = tmp * X1 val = !tmp * X2 However if I change it to: tmp = evaluate and result is 0 or 1 (nothing else) val = tmp * X1 if (!tmp) val = !tmp * X2 It works fine... but it is useless because of "if", which need to be eliminated I honestly don´t understand it Posted Image . I tried compilation with NO and FULL optimalization, result is same
