• How can I get a 2D texture to rotate like a compass in XNA?

  - by IronGiraffe

  I'm working on a small maze puzzle game and I'm trying to add a compass to make it somewhat easier for the player to find their way around the maze. The problem is: I'm using XNA's draw method to rotate the arrow and I don't really know how to get it to rotate properly. What I need it to do is point towards the exit from the player's position, but I'm not sure how I can do that. So does anyone know how I can do this? Is there a better way to do it?

• What are some ways to texture map a terrain?

  - by ApocKalipsS

  I'm working with XNA on a 3D Game, and I'm trying to have a proper and nice environnement. I actually followed a tutorial to create a terrain from a heightmap. To texture it, I just apply a grass texture on it and tile it a number of times. But what I want to do is to have a really realistic texturing, but also generate it automatically (for example if I want to use Perlin noise to generate a terrain and then texture it). I already learned about multi-texturing, loading a map file with different colors for different textures, but I don't think this is really efficient, for instance for cliffs or very steep areas it will tile a texture badly as it's a view from the top. (Also, I don't know how I'll draw roads or dirt paths with that.) I'm looking for an efficient solution to realistically texture mapping procedurally-generated terrain.

• C# Rendering Engine for Roguelike [closed]

  - by Haedrian

  I'm trying my hand at designing a roguelike, and I need a pretty simple 2D rendering engine that works with C# Its as simple as it gets, I want to be able to drop sprites somewhere on a grid, with some sort of menus/text on the side; that sort of thing. The (very complicated) game itself would be decoupled from the interface I've looked into a number of engines and they all seem to be very complicated/support much more things than I need. Right now I'm planning on making my own using either XNA or OpenTK - but I was wondering whether anyone has any suggestions for less-complicated rendering engines which might make my job easier. Thanks.

• Efficient skeletal animation

  - by Will

  I am looking at adopting a skeletal animation format (as prompted here) for an RTS game. The individual representation of each model on-screen will be small but there will be lots of them! In skeletal animation e.g. MD5 files, each individual vertex can be attached to an arbitrary number of joints. How can you efficiently support this whilst doing the interpolation in GLSL? Or do engines do their animation on the CPU? Or do engines set arbitrary limits on maximum joints per vertex and invoke nop multiplies for those joints that don't use the maximum number? Are there games that use skeletal animation in an RTS-like setting thus proving that on integrated graphics cards I have nothing to worry about in going the bones route?

• Android loading screens blocking, good practice?

  - by Oren

  I've noticed many (if not all) android games don't support the "back" button functionality during their loading screens. Which leads to some frustrating moments when a user accidentally starts up the game and has to wait for the long loading stage to end in order to close it. So my questions are: 1) Why is that ? Is there a good reason to avoid something like asynchronous loading (or some other solution to this problem) in android games ? 2) If there is no good reason not to support this functionality, what would be the best way to accomplish it ?

• FBO rendering different result between Glaxay S2 and S3

  - by BruceJones

  I'm working on a pong game and have recently set up FBO rendering so that I can apply some post-processing shaders. This proceeds as so: Bind texture A to framebuffer Draw balls Bind texture B to framebuffer Draw texture A using fade shader on fullscreen quad Bind screen to framebuffer Draw texture B using normal textured quad shader Neither texture A or B are cleared at any point, this way the balls leave trails on screen, see below for the fade shader. Fade Shader private final String fragmentShaderCode = "precision highp float;" + "uniform sampler2D u_Texture;" + "varying vec2 v_TexCoordinate;" + "vec4 color;" + "void main(void)" + "{" + " color = texture2D(u_Texture, v_TexCoordinate);" + " color.a *= 0.8;" + " gl_FragColor = color;" + "}"; This works fine with the Samsung Galaxy S3/ Note2, but cause a strange effect doesnt work on Galaxy S2 or Note1. See pictures: Galaxy S3/Note2 Galaxy S3/Note2 Galaxy S2/Note Galaxy S2/Note Can anyone explain the difference?

• XNA GameTime TotalGameTime slower than real time

  - by robasaurus

  I have set-up an empty test project consisting of a System.Diagnostics.Stopwatch and this in the draw method: spriteBatch.DrawString(font, gameTime.TotalGameTime.TotalSeconds.ToString(), new Vector2(100, 100), Color.White); spriteBatch.DrawString(font, stopwatch.Elapsed.TotalSeconds.ToString(), new Vector2(100, 200), Color.White); The GameTime.TotalGameTime displayed is slower than the stop watch (by about 5 seconds per minute) even though GameTime.IsRunningSlowly is always false, why is this? The reason this is an issue is because I have a server which uses stopwatch and it is faster than my client game. For instance my client notifies the server it has dropped a mine which explodes in one minute. Because the stopwatch is faster the server state explodes the mine before the client and they are out of sync. I don't want to have to notify the client when the server explodes it as this would use unnecessary bandwidth.

• How to divide hex grid evenly among n players?

  - by manabreak

  I'm making a simple hex-based game, and I want the map to be divided evenly among the players. The map is created randomly, and I want the players to have about equal amount of cells, with relatively small areas. For example, if there's four players and 80 cells in the map, each of the players would have about 20 cells (it doesn't have to be spot-on accurate). Also, each player should have no more than four adjacent cells. That is to say, when the map is generated, the biggest "chunks" cannot be more than four cells each. I know this is not always possible for two or three players (as this resembles the "coloring the map" problem), and I'm OK with doing other solutions for those (like creating maps that solve the problem instead). But, for four to eight players, how could I approach this problem? As always, any and all help is appreciated. :)

• Audio libraries for PC indie games [closed]

  - by bluescrn

  Possible Duplicate: Cross-Platform Audio API Suggestions What options are out there these days for audio playback/mixing in C++? Primarily for Windows, but portability (particularly to Mac and iOS) would be desirable. For a small indie game, potentially commercial, though - so I'm looking for something free/low-cost. My requirements are fairly basic - I don't need 3D sound, or many-channels - simple stereo is fine. Just need to be able to mix sound effects and a music stream, maybe decoding one or more compressed audio formats (.ogg/.mp3 etc), with all the basic controls over looping, pitch, volume, etc. Is OpenAL more-or-less the standard choice, or are there other good options out there?

• Re-sizing the form without scaling the GUI

  - by Bmoore

  I am writing a turn based strategy game in C#. My GUI implementation consists of class that extends Form containing a class that extends Panel. When I render the GUI I draw to the paint method in the panel. I am trying to figure out what is the best way for handling form re-size events. I know I want a minimum window size, but I would prefer to not have a maximum or a set size. Ideally the GUI would reveal more/less of the map as the user changes the window size. I would like to avoid scaling the graphics if at all possible. What is the best way to handle re-size events?

• How can I support scrolling when using batched rendering for my tiles?

  - by dardanel

  I have tiled map 100*75 and tiles are 32*32 pixel.I want to use batching for performance .I don't figure it out , because of my game needs scrolling and every frame i draw 22*16 tiles (my screen is 20*16 tile) .I thought that batching tiles for every frame .Is it good or any suggestion? edit :to more clarify I want to use occlusion culling and batching at the same time.I thought that drawing only visible areas and batching them together .But there is a something i couldn't figure out .When scrolling screen with translate matrix , if one row become invisible , I bind new row and batch them again.Every batched objects needs to buffer again.So I batch tiles and buffer to VBO every time when one row become invisible .I don't know these way is efficient or not .This is my question .And i am open to any suggestions.

• Predicted target location

  - by user3256944

  I'm having an issue with calculating the predicted linear angle a projectile needs to move in to intersect a moving enemy ship for my 2D game. I've tried following the document here, but what I've have come up with is simply awful. protected Vector2 GetPredictedPosition(float angleToEnemy, ShipCompartment origin, ShipCompartment target) { // Below obviously won't compile (document wants a Vector, not sure how to get that from a single float?) Vector2 velocity = target.Thrust - 25f; // Closing velocity (25 is example projectile velocity) Vector2 distance = target.Position - origin.Position; // Range to close double time = distance.Length() / velocity.Length(); // Time // Garbage code, doesn't compile, this method is incorrect return target.Position + (target.Thrust * time); } I would be grateful if the community can help point out how this is done correctly.

• Civilization 4: time in own scenario runs up too quickly.

  - by oKtosiTe

  In Civilization 4 (Beyond the Sword) I started making a scenario that focuses on the colonization of North America. For added realism, I set the StartYear=1780. Everytime I run the scenario, the time runs up far too quickly–probably because I set Era=ERA_ANCIENT and GameTurn=0–so that after just twenty turns the clock nears present day. I'm not really sure how to go fix this, other than by playing an actual marathon game from the start up to the year 1780 and copy over the values. Is there any way to calculate/know the right values for my scenario?

• Loading Texture2D is extremly slow on XBOX360

  - by AvrDragon

  I have ~100 sprites for each level im my XNA game. On windows it takes ~2 seconds to load them all. Unfortunately on XBOX360 it takes ~30-60 seconds. Am i doing something wrong? Essentially the loading code ist just like this: Texture2D sprite1 = levelContent.Load<Texture2D>("images/level_1/my_sprite_1"); ... Texture2D sprite100 = levelContent.Load<Texture2D>("images/level_1/my_sprite_100"); (i use an own content manager for each level to release all level-specific textures at once) Of course i can reduse the ammount of sprites using a spritesheet, but it's extremly painfull for me now. Do i have a better option? And just curious - why is there such huge difference in image loading time?

• Polygon count budget

  - by Lautaro

  Is there any smart way to think about polygon budget relating to PC gaming today? My game will have one static 3d background scene and two fighters. No more enemies. I am thinking about having animated 3d models in the background for atmosphere, like spectators. So how could i find out what the polygon count for the player models and background scenarios could be. I guess the question is, what is a for today typical polygon count that most PCs can handle?

• Where can I find resources for RPG Character Sprites? [closed]

  - by IcySnow

  I'm developing a turn-based 2D RPG game. Everything's going fine except the lack of characters' sprites such as moving, attacking animation, etc.... By characters I mean both human-like and monster-like creatures. Is there a website providing sprites for free? Or a program (free or paid, whichever is fine) which will let me create sprites from scratch and automatically generate the images? I tried my best to search for one but the best I've managed to find so far is http://spriters-resource.com/. However, is there something else similar and better out there?

• Updating "Inactive" Chunks

  - by Conner Bryan

  In my game, the only chunks (4x4 areas of tiles) in memory are the ones that the player is in. However, chunks need to have updates applied to them over time. A (likely) well-known example would be MineCraft: even if the player isn't in a chunk, the wheat still needs to grow over time. My current solution is to call a method and pass in the time since the chunk was active.. but what if the chunk depends on nearby chunks for information, i.e. vines spreading or similar? Is there any reasonable solutions to this problem, or should I simply not depend on nearby chunks?

• Do you think that in the future it'll be possible to develop games on OS X by using Python and the latest library "Sprite kit" made by Apple? [on hold]

  - by Cesco

  I don't understand a lot about game engines and modules for Python, even though I'm aware of the existance of PyGame and Pyglets, so please don't bash me too hard if I'll wrote something wrong in this question :-) When I upgraded my Mac to the latest version of OS X, I noticed for the first time that Apple is providing a library named Sprite kit for developing games on both iOS and OS X. It looks to me fairly complete, and the fact is managed by a big company gives me the impression of being well-supported for the time being; in summary, it looks... cool. Actually in order to take advantage of "Sprite kit" you need to code in Obj-C. Since I don't know Obj-C but only a little bit of Python, do you think that there's a chance that sooner or later someone will make a wrapper for Python ? Thank you very much and best regards

• Which Git-based MIS to track workflow like Trac/Redmine but on console minimastically?

  - by hhh

  Definitions MIS = management information system Some list about console based solutions here and some GUI-hacks here. Been fed up to install all those dependencies and no make -files with GUI -things so which console-based MIS would you suggest for a game-development team with graphical -repo, animation -repo, code -repo, stories -repo, etc ? P.s. I do use Git -submodules and the reason for repo -fragmentation is due to roles and size, certain repos such as graphic -repos tend to be quite large so better to keep them separate. Perhaps useful to readers interested about this http://stackoverflow.com/questions/5881578/trac-vs-redmine https://github.com/jchris/sofa

• record and replay directinput events

  - by cloudraven

  I am trying to build a record and replay system for a couple of games. I was wondering if I can make a general replay engine using directinput rather than doing an specific implementation for each game. Recording DirectInput events doesn't seem to be that much of a problem, but I don't know if there is a way to play them back. My question is, is there a way to feed DirectInput events from a log and make DirectInput believe that they came from mouse/joystick/keyboard? I assume it is unlikely, but if there is a way I would be interested in learning about it.

• Faking Display tree (Sprite) parent child relationships with rasters (BitmapData) in ActionScript 3

  - by Arthur Wulf White

  I am working with Rasters (bitmapData) and blliting (copypixels) in a 2d-game in actionscript 3. I like how you can move a sprite and it moves all it's children, and you can simultaneously move the children creating an interesting visual effect. I do not want to use rotation or scaling however cause I do not know how that can be done without hampering with performance. So I'm not simulating Sprite parent-child behavior and sticking to the movement on the (x, y) axis. What I am planning to do is create a class called RasterContainer which extends bitmapData that has a vector of children of type Raster(extending bitmapData), now I am planning to implement recursive rendering in RasterContainer, that basically copyPixels every child, only changing their (x, y) offset to reflect their parent's offset. My question is, has this been implemented in an existing framework? Is this a good plan? Do I expect a serious performance hit for using recursive methods this way?

• Swapping axis labels between 2D and 3D coordinates

  - by Will

  My game world is 3D. The map is only 2D, however. It is natural to think of the map as having an X and Y axis. And it is natural to think of the world has having an X, Y and Z axis, where Y is upwards. That is to say, X Y in 2D map coordinates is X Z in 3D coordinates. What conventions and approaches do you have to keeping things straight at a code level to make mapping between them natural? (Is Y usually upwards in 3D? Or do you have X and Z in map coordinates, or?)

• How to use a mask texture with Kobold2D

  - by alex

  I am an iOS developer but I'm new to cocos2d. I'm working on new game, I use Kobold2D, have cocos2d installed too, and I want to make this effect: I know how is done with Flash, but can't make it with Kobold2D. There's 2 images with the same size: one is a low-res image for the background and the second is a hi-res over the first one. When the "reticle" mask moves, it reveals the second image inside the circle and the background is visible outside only. I googled with no success, saw some Ray Wenderlich projects they weren't helpful.

• How many VBOs should I use and should I keep a copy of their data?

  - by CSharpie

  Firstofall, I am sorry if my question is to broad. I am developing a tile based game and switched from those gl.Begin calls to using VBOs. This is kind of working allready, I managed to render a hexagonal polygon with a simple shader applied. What I am not sure is, how to implement the "whole" tile concept. Concrete the questions are: Is it better to create 1 VBO for a single tile and render it n-Times in every different position, or render one huge VBO that represents the whole "world" Depending on the answer above, what is the best way to draw a "linegrid". Overlay with the same vbo using the respecting polygon.mode , or is there a way to let the shader to this? How would frustum-culling or mousepicking work then, do i need to keep the VBO-data in memory?

• Adding a short delay between bullets

  - by Sun

  I'm having some trouble simulating bullets in my 2D shooter. I want similar mechanics to Megaman, where the user can hold down the shoot button and a continues stream of bullets are fired but with a slight delay. Currently, when the user fires a bullet in my game a get an almost laser like effect. Below is a screen shot of some bullets being fired while running and jumping. In my update method I have the following: if(gc.getInput().isKeyDown(Input.KEY_SPACE) ){ bullets.add(new Bullet(player.getPos().getX() + 30,player.getPos().getY() + 17)); } Then I simply iterate through the array list increasing its x value on each update. Moreover, pressing the shoot button (Space bar) creates multiple bullets instead of just creating one even though I am adding only one new bullet to my array list. What would be the best way to solve this problem?
