• Calculating Hit Accuracy score in a game

  - by N0xus

  I'm currently in the process of making a scoreboard for my game. One of things I would like to display is the players accuracy in the amount of hits they had in game. However, I have never done this before and I've no idea how to go about doing this. Is there a commonly used algorithm out there that can help me calculate this, or has someone found a way to calculate this fairly easily? Any help with this would be appreciated.

• How to detect GLSL warnings?

  - by msell

  After compiling a shader with glCompileShader, I can call glGetShaderiv with GL_COMPILE_STATUS to check if the shader compiled successfully. I can also call glGetShaderInfoLog to get information about possible errors, warnings or other info. The information log returned by this function is unspecified. In a tool where users can write their own shaders, I would like to print all errors and warnings from the compilation, but nothing if no warnings or errors were found. The problem is that the GL_COMPILE_STATUS returns only false if the compilation failed and true otherwise. If no problems were found, some drivers return empty info log from glGetShaderInfoLog, but some drivers can return something else such as "No errors.", which I do not want to print to the user. How is this problem generally solved?

• About to graduate from good school without any progamming skills

  - by newprint

  Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from a good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been taught how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

• Dynamic Jump spot

  - by Pasquale Sada

  I have an initial velocity V(Vx,Vy,VZ) and a spot where he stands still at S(Sx,Sy,Sz). What I'm trying to achieve is a jump on a spot E(Ex,Ey,Ez) where you have clicked on(only lower or higher spot, because I've in place a simple steering behavior for even terrains). There are no obstacle around. I've implemented a formula that can make him jump in a precise way on a spot but you need to declare an angle: the problem arise when the selected spot is straight above your head. It' pretty lame that the char hang there and can reach a thing that is 1cm above is head. I'll share the code I'm using: Vector3 dir = target - transform.position; // get target direction float h = dir.y; // get height difference dir.y = 0; // retain only the horizontal direction float dist = dir.magnitude ; // get horizontal distance float a = angle * Mathf.Deg2Rad; // convert angle to radians dir.y = dist * Mathf.Tan(a); // set dir to the elevation angle dist += h / Mathf.Tan(a); // correct for small height differences // calculate the velocity magnitude float vel = Mathf.Sqrt(dist * Physics.gravity.magnitude / Mathf.Sin(2 *a)); return vel * dir.normalized;

• Making a startscreen for an HTML5 game?

  - by hustlerinc

  How would I make a start screen for a game using HTML5 canvas? I'm not looking for something advanced, just the new game button and highscore link etc. The question might be stupid, but I've never done anything similar, and the tutorials out there don't cover the subject. Is it enough to just make a fillText with an onclick function? Is there a way to find out the size of the text? Help appreciated.

• Cocos2D: Upgrading from OpenGL 1.1 to 2.0

  - by Alex

  I have recently starting upgrading my ios game to the latest Cocos2D (2.0 rc), and I am having some difficulties upgrading my texture generation code to OpenGL 2.0. In the old version I generated images with this code: CCRenderTexture *rt = [CCRenderTexture renderTextureWithWidth:WIDTH height:HEIGHT]; [rt beginWithClear:bgColor.r g:bgColor.g b:bgColor.b a:bgColor.a]; glDisable(GL_TEXTURE_2D); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glVertexPointer(2, GL_FLOAT, 0, verts); glColorPointer(4, GL_FLOAT, 0, colors); glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)nVerts); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glEnable(GL_TEXTURE_2D); [rt end]; But since OpenGL 2.0 works differently this code won't work. What is the best way to use the new OpenGL?

• Cookie/money/point clicker game origin?

  - by gavenkoa

  I can't find myself origin of Clicker like games. It's where the goal is to gain points through clicks and acquired enhancement. There's only one strategy in the game - deciding how efficiently spend point on enhancement (see formulas). I've seen many games like this, but it seems that most don't have a home page or have an unknown publisher. Some well known games of this type: Candy Box Cookie Clicker Cow Clicker Who is first implemented this idea (not only clicking but with investment model - when player must decide what improve to faster gather points)?

• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

• I Need Help With A Game (Well The API)! [closed]

  - by user1758938

  I'm not "sure" which API (or language) I should use for a little 3D FPS game I'm gonna make although I don't have helpers lol. Anyway I'm ok with Java, C# and C++ but I need a good setup (easy to use) with the tools I need to make the game. I tried things like XNA but I want to check other options first because I don't like how it makes a installer and stuff, it's really annoying. I Need A API That Can Do These Things: 3D Rendering Input Sound And If It's Not Too Much To Ask Some Cool Shaders, Dynamic Lighting And A 3D Sound System Im "Ok" If I Have To Use Multiple APIs To Do This But Please Help Me!

• Ray Picking Problems

  - by A Name I Haven't Decided On

  I've read so many answers on here about how to do Ray Picking, that I thought I had the idea of it down. But when I try to implement it in my game, I get garbage. I'm working with LWJGL. Here's the code: public static Ray getPick(int mouseX, int mouseY){ glPushMatrix(); //Setting up the Mouse Clip Vector4f mouseClip = new Vector4f((float)mouseX * 2 / 960f - 1, 1 - (float)mouseY * 2 / 640f ,0 ,1); //Loading Matrices FloatBuffer modMatrix = BufferUtils.createFloatBuffer(16); FloatBuffer projMatrix = BufferUtils.createFloatBuffer(16); glGetFloat(GL_MODELVIEW_MATRIX, modMatrix); glGetFloat(GL_PROJECTION_MATRIX, projMatrix); //Assigning Matrices Matrix4f proj = new Matrix4f(); Matrix4f model = new Matrix4f(); model.load(modMatrix); proj.load(projMatrix); //Multiplying the Projection Matrix by the Model View Matrix Matrix4f tempView = new Matrix4f(); Matrix4f.mul(proj, model, tempView); tempView.invert(); //Getting the Camera Position in World Space. The 4th Column of the Model View Matrix. model.invert(); Point cameraPos = new Point(model.m30, model.m31, model.m32); //Theoretically getting the vector the Picking Ray goes Vector4f rayVector = new Vector4f(); Matrix4f.transform(tempView, mouseClip, rayVector); rayVector.translate((float)-cameraPos.getX(),(float) -cameraPos.getY(),(float) -cameraPos.getZ(), 0f); rayVector.normalise(); glPopMatrix(); //This Basically Spits out a value that changes as the Camera moves. //When the Mouse moves, the values change around 0.001 points from screen edge to edge. System.out.format("Vector: %f %f %f%n", rayVector.x, rayVector.y, rayVector.z); //return new Ray(cameraPos, rayVector); return null; } I don't really know why this isn't working. I was hoping some more experienced eyes might be able to help me out. I can get the camera position like a champ, it's the vector the rays going in that I can't seem to get right. Thanks.

• MarteEngine Tile Collision

  - by opiop65

  I need to add collision to my tile map using MarteEngine. MarteEngine is built of of slick2D. Here's my tile generation code: Code: public void render(GameContainer gc, StateBasedGame game, Graphics g) throws SlickException { for (int x = 0; x < 16; x++) { for (int y = 0; y < 16; y++) { map[x][y] = AIR; air.draw(x * GameWorld.tilesize, y * GameWorld.tilesize); } } for (int x = 0; x < 16; x++) { for (int y = 7; y < 8; y++) { map[x][y] = GRASS; grass.draw(x * tilesize, y * tilesize); } } for (int x = 0; x < 16; x++) { for (int y = 8; y < 10; y++) { map[x][y] = DIRT; dirt.draw(x * tilesize, y * tilesize); } } for (int x = 0; x < 16; x++) { for (int y = 10; y < 16; y++) { map[x][y] = STONE; stone.draw(x * tilesize, y * tilesize); } } super.render(gc, game, g); } And one of my tile classes (they're all the same, the image names are just different): Code: package MarteEngine; import org.newdawn.slick.Image; import org.newdawn.slick.SlickException; import it.randomtower.engine.entity.Entity; public class Grass extends Entity { public static Image grass = null; public Grass(float x, float y) throws SlickException { super(x, y); grass = new Image("res/grass.png"); setHitBox(0, 0, 50, 50); addType(SOLID); } } I tried to do it like this: Code: for (int x = 0; x < 16; x++) { for (int y = 7; y < 8; y++) { map[x][y] = GRASS; Grass.grass.draw(x * tilesize, y * tilesize); } } But it gave me a NullPointerException. No idea why, everything looks initialized right? I would be very grateful for some help!

• OpenGL ES 2.0 gluUnProject

  - by secheung

  I've spent more time than I should trying to get my ray picking program working. I'm pretty convinced my math is solid with respect to line plane intersection, but I believe the problem lies with the changing of the mouse screen touch into 3D world space. Heres my code: public void passTouchEvents(MotionEvent e){ int[] viewport = {0,0,viewportWidth,viewportHeight}; float x = e.getX(), y = viewportHeight - e.getY(); float[] pos1 = new float[4]; float[] pos2 = new float[4]; GLU.gluUnProject( x, y, 0.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos1, 0); GLU.gluUnProject( x, y, 1.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos2, 0); } Just as a reference I've tried transforming the coordinates 0,0,0 and got an offset. It would be appreciated if you would answer using OpenGL ES 2.0 code.

• How do I make A* check all diagonal and orthogonal directions?

  I'm making a turn-based tactical game and I'm trying to implement the A* algorithm. I've been following a tutorial and got to this point, but my characters can't move diagonally up and left.

• How to acheive a smooth 2D lighting effect?

  - by Cyral

  I'm making a tile based game in XNA So currently my lightning looks like this: How can I get it to look like this? Instead of each block having its own tint, it has a smooth overlay. I'm assuming some sort of shader, and to tell it the lighting and blur it some how. But im not an expert with shaders. My current lighting calculates the light, and then passes it to a spritebatch and draws with a color parameter EDIT: No longer uses spritebatch tint, I was testing and now pass parameters to set the light values. But still looking for a way to smooth it

• How do I improve terrain rendering batch counts using DirectX?

  - by gamer747

  We have determined that our terrain rendering system needs some work to minimize the number of batches being transferred to the GPU in order to improve performance. I'm looking for suggestions on how best to improve what we're trying to accomplish. We logically split our terrain mesh into smaller grid cells which are 32x32 world units. Each cell has meta data that dictates the four 256x256 textures that are used for spatting along with the alpha blend data, shadow, and light mappings. Each cell contains 81 vertices in a 9x9 grid. Presently, we examine each cell and determine the four textures that are being used to spat the cell. We combine that geometry with any other cell that perhaps uses the same four textures regardless of spat order. If the spat order for a cell differs, the blend map is adjusted so that the spat order is maintained the same as other like cells and blending happens in the right order too. But even with this batching approach, it isn't uncommon when looking out across an area of open terrain to have between 1200-1700 batch count depending upon how frequently textures differ or have different texture blends are between cells. We are only doing frustum culling presently. So using texture spatting, are there other alternatives that can reduce the batch count and allow rendering to be extremely performance-friendly even under DirectX9c? We considered using texture atlases since we're targeting DirectX 9c & older OpenGL platforms but trying to repeat textures using atlases and shaders result in seam artifacts which we haven't been able to eliminate with the exception of disabling mipmapping. Disabling mipmapping results in poor quality textures from a distance. How have others batched together terrain geometry such that one could spat terrain using various textures, minimizing batch count and texture state switches so that rendering performance isn't negatively impacted?

• XNA Rendering vertices that only appear within the cameras view

  - by user1157885

  I'm making a game in XNA and I recall hearing that professionally made games use a technique to only render the polygons that appear within the cameras projection. I've been trying to find something on this to do something similar in my game, could anyone point me in the right direction? Right now all I have is a plane/grid of vertices that you can set the X/Y on which is drawn using DrawUserIndexedPrimitives, but I plan to make a bunch of props as scenery items and I can imagine myself running into issues later on if I don't address this now. Thanks

HumanPlayerController: to control the user input ComputerPlayerController: contains the AI of the computer PlayerController: is an interface with the makeTurn() method. It's implemented by HumanP.C. and ComputerP.C. HumanPlayerController implements ActionListener too. But what is the right way to access to the GameFrame buttons?

• How to keep track of previous scenes and return to them in libgdx

  - by MxyL

  I have three scenes: SceneTitle, SceneMenu, SceneLoad. (The difference between the title scene and the menu scene is that the title scene is what you see when you first turn on the game, and the menu scene is what you can access during the game. During the game, meaning, after you've hit "play!" in the title scene.) I provide the ability to save progress and consequently load a particular game. An issue that I've run into is being able to easily keep track of the previous scene. For example, if you enter the load scene and then decide to change your mind, the game needs to go back to where you were before; this isn't something that can be hardcoded. Now, an easy solution off the top of my head is to simply maintain a scene stack, which basically keeps track of history for me. A simple transaction would be as follows I'm currently in the menu scene, so the top of the stack is SceneMenu I go to the load scene, so the game pushes SceneLoad onto the stack. When I return from the load scene, the game pops SceneLoad off the stack and initializes the scene that's currently at the top, which is SceneMenu I'm coding in Java, so I can't simply pass around Classes as if they were objects, so I've decided implemented as enum for eac scene and put that on the stack and then have my scene managing class go through a list of if conditions to return the appropriate instance of the class. How can I implement my scene stack without having to do too much work maintaining it?

Do I use less details in all the grahpics? Tiny Wings has the same horizontal movement speed as in my game but it doesn't suffer from these problems. Are there any other really fast side-scrollers I could take as a reference?

• Cocos2d: Adding a CCSequence to a CCArray

  - by Axort

  I have a problem with an action performed by a sprite. I have one CCSequence in a CCArray and I have an scheduled method (is called every 5 seconds) that make the sprite run the action. The action is performed correctly only the first time (the first 5 seconds), after that, the action do whatever it wants lol. Here is the code: In .h - @interface PowerUpLayer : CCLayer { PowerUp *powerUp; CCArray *trajectories; } @property (nonatomic, retain) CCArray *trajectories; In .mm - @implementation PowerUpLayer @synthesize trajectories; -(id)init { if((self = [super init])) { [self createTrajectories]; self.isTouchEnabled = YES; [self schedule:@selector(spawn:) interval:5]; } return self; } -(void)createTrajectories { self.trajectories = [CCArray arrayWithCapacity:1]; //Wave trajectory ccBezierConfig firstWave, secondWave; firstWave.controlPoint_1 = CGPointMake([[CCDirector sharedDirector] winSize].width + 30, [[CCDirector sharedDirector] winSize].height / 2);//powerUp.sprite.position.x, powerUp.sprite.position.y); firstWave.controlPoint_2 = CGPointMake([[CCDirector sharedDirector] winSize].width - ([[CCDirector sharedDirector] winSize].width / 4), 0); firstWave.endPosition = CGPointMake([[CCDirector sharedDirector] winSize].width / 2, [[CCDirector sharedDirector] winSize].height / 2); secondWave.controlPoint_1 = CGPointMake([[CCDirector sharedDirector] winSize].width / 2, [[CCDirector sharedDirector] winSize].height / 2); secondWave.controlPoint_2 = CGPointMake([[CCDirector sharedDirector] winSize].width / 4, [[CCDirector sharedDirector] winSize].height); secondWave.endPosition = CGPointMake(-30, [[CCDirector sharedDirector] winSize].height / 2); id bezierWave1 = [CCBezierTo actionWithDuration:1 bezier:firstWave]; id bezierWave2 = [CCBezierTo actionWithDuration:1 bezier:secondWave]; id waveTrajectory = [CCSequence actions:bezierWave1, bezierWave2, [CCCallFuncN actionWithTarget:self selector:@selector(setInvisible:)], nil]; [self.trajectories addObject:waveTrajectory]; //[powerUp.sprite runAction:bezierForward]; // [CCMoveBy actionWithDuration:3 position:CGPointMake(-[[CCDirector sharedDirector] winSize].width - powerUp.sprite.contentSize.width, 0)] //[powerUp.sprite runAction:[CCSequence actions:bezierWave1, bezierWave2, [CCCallFuncN actionWithTarget:self selector:@selector(setInvisible:)], nil]]; } -(void)setInvisible:(id)sender { if(powerUp != nil) { [self removeChild:sender cleanup:YES]; powerUp = nil; } } This is the scheduled method: -(void)spawn:(ccTime)dt { if(powerUp == nil) { powerUp = [[PowerUp alloc] initWithType:0]; powerUp.sprite.position = CGPointMake([[CCDirector sharedDirector] winSize].width + powerUp.sprite.contentSize.width, [[CCDirector sharedDirector] winSize].height / 2); [self addChild:powerUp.sprite z:-1]; [powerUp.sprite runAction:((CCSequence *)[self.trajectories objectAtIndex:0])]; } } I don't know what is happening; I never modify the content of the CCSequence after the first time.

• Cutting out smaller rectangles from a larger rectangle

  - by Mauro Destro

  The world is initially a rectangle. The player can move on the world border and then "cut" the world via orthogonal paths (not oblique). When the player reaches the border again I have a list of path segments they just made. I'm trying to calculate and compare the two areas created by the path cut and select the smaller one to remove it from world. After the first iteration, the world is no longer a rectangle and player must move on border of this new shape. How can I do this? Is it possible to have a non rectangular path? How can I move the player character only on path? EDIT Here you see an example of what I'm trying to achieve: Initial screen layout. Character moves inside the world and than reaches the border again. Segment of the border present in the smaller area is deleted and last path becomes part of the world border. Character moves again inside the world. Segments of border present in the smaller area are deleted etc.

• Free vs. Paid: Picking a Financial Model

  - by ashes999

  I finally embarked upon my first "paid" game. What this means is that I will incorporate some sort of monetization strategy in my game. This may mean making the app pay-to-download, making it "freemium" with paid content, or something else. Having never done something like this, I'm at a complete loss as to how to figure out what I should do. I know a couple of models (pay to download, freemium, etc.) and I can brainstorm some ideas. But how do I figure out what strategy to use? Perhaps there's some body of research on this? (I recall reading that MMOs popular in Korea use a model where cosmetic changes only are pay-to-buy; everything else is free).

• How to avoid circular dependencies between Player and World?

  - by futlib

  I'm working on a 2D game where you can move up, down, left and right. I have essentially two game logic objects: Player: Has a position relative to the world World: Draws the map and the player So far, World depends on Player (i.e. has a reference to it), needing its position to figure out where to draw the player character, and which portion of the map to draw. Now I want to add collision detection to make it impossible for the player to move through walls. The simplest way I can think of is to have the Player ask the World if the intended movement is possible. But that would introduce a circular dependency between Player and World (i.e. each holds a reference to the other), which seems worth avoiding. The only way I came up with is to have the World move the Player, but I find that somewhat unintuitive. What is my best option? Or is avoiding a circular dependency not worth it?
