Hello stackoverflow community ! I am trying to figure out how to architect my game using cocos2d. My problem is that cocos2d's physics engine (i'm talking about chipmunk) lies in a world behind sprites. When I move the sprite, I'm wondering if I should *1) be moving it by applying forces on the physics body behind it OR 2) if i ...
Hello wonderful people ! Here is my problem. I have a chipmunk's rigid body (a soda can standing up) that i want to change its center of gravity to the bottom of the object so it can fall on its flank when a force is applied to its upper part. Am I on the right track? 1) For some reason, I am having trouble setting the body's center ...
It is my understanding that a texture atlas is basically a single texture that contains many smaller textures and that they are useful for making games or animations faster because they allow you to access many animation frames by loading a single file rather than files for each and every frame. So, in discussions of texture atlases, I ...

Hi everyone, I'm having an odd issue trying to present an MPMediaPickerController using presentModalViewController. I had it working fine, but recently (perhaps as of 3.1, I don't exactly recall the last time it was working) the MPMediaPickerController just refuses to show itself. The screen just remains black, with nothing but the sta...
I'm looking for something that does a similar call, but using cocos2d... the idea is to enlarge the sprite and then fade it out... Here's is a similar call in core animation: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:ANIM_NORMAL]; someView.alpha = 0.0; someView.transform = CGAffineTransformMakeScale (3.0, 3....

Have a project with a TRIANGLE shaped graphic in a sprite. I am arranging these sprites in a grid so that their rectangles are all overlapping. As sprites get touched their z-order is being changed (by me) to put them on the top of zOrder. I am using Cocos 0.8.1 and the touch dispatcher method. I have touches working but obviously the "...

I'm working on a Tetris clone in Cocos2d for the iPhone and I'm using a Block class of Sprites for the individual blocks and a Tetromino CocosNode class that the user controls in order to move the Blocks. All of these Blocks move around in a 20 by 10 grid of empty Blocks on the GameBoardLayer. When the block finishes falling, I'd like ...
After learning more about how monotouch works, I believe I know the answer to this anyway, but can you use the cocos2d-iphone framework with monotouch? I believe most likely this will be a 'no', because cocos2d is an an objective c library and there would most probably have to be some sort of .net port for this to be achieved? is that so...
