Hello, I just finished reading some of the cocos2d documentation, and as far as I understand to add a background image to a layer you have to do something like: Sprite * bg = [Sprite spriteWithFile:@"Background.png"]; [layer addChild:bg z:0]; Allthough as far as my testing goes you can just directly add the sprite to the scene like t...
I have a code that set's a bow's angle according to where you have touched the screen. a simple "bow.rotation = X" command is performed on the ccTouchesMoved event. the problem is, that while running the code on 0.7.1 of cocos2d against 0.9 or 0.8.2 it worked way better, in 0.9 and 0.8.2 it seems like it skippes some of the touchesmove e...
Hello, I am developing a game that intends to toss an object but instead of having it being tossed horizontally I would like to simulate it being thrown along the imaginary z axis that is simulate depth in my game.

Hello, I am developing an iphone game using cocos2d and have it set to to show the FPS. Now most of the time the application will start and run at 60 fps, However apparently randomly sometimes the application will start and top at only 40 fps.

I need to implement a little bit of Ai that can apply an impulse to a rigid body in order to hit a target. Like a cannon ball being fired from a cannon. I'm using Chipmunk Dynamics for the physics engine. My maths is terrible, as is my physics, but i've been reading up, and with a little help from SO and the following from this wikipedi...

Hello, I am completely new to chipmunk and I have just been using it for a few days, so I'm guessing this is something pretty obvious, however I cannot find any documentation for this. Is there any callback or method in chipmunk that tells you that 2 given shapes have collided?. If not is the best way to simply use cgrectcontains on th...
UPDATE: I'm a doofus. What's happening is obvious. The Animation first sets the layers position to it's current position. But I've told the layer to divide any setPosition coordinates by pRatio. So it's not going to CGPoint(0,0) but something like CGPoint(0.032, 0). I've fixed it like this: - (void) setPosition:(CGPoint)point { if(!...
Hi everyone. I have some trouble with my game (using Cocos2D). I have an introduction, then it will go to the game afterward. The thing here is, on the simulator, it always appears at real-time when it switches scene Intro to GamePlay. But in the actual phone, I know it would be slower and take more time to switch. But before the player...

All I really want to do is Transform my rectangular Sprite into a trapezoid like this: / \ / \ /__________\ Has anyone done this with CGAffineTransforms or...
I am considering using the excellent looking Cocos2d for a motion graphics project. However, Cocos2d is intended for games, rather than producing an MPEG stream. Is it possible to save the output from a Cocos2d script to a MOV or MPG file? Ideally this needs to be done in a direct manner, not using a screen capture as this would not mee...

I cannot simply render them into the sprite png, or the shadows will overlap adjacent sprites. I also cannot simply put shadows on a lower la...
