Question

I want to animate a 20 wagon train in iphone. The train will move left to right. Each wagon will have a different animation. I was confused how to do it. Because the images are large and 20 images at one time would cause memory warnings.

Can anyone suggest how to go about it. Should I use cocos2d for this?

Thanks!

Answer 1

I would do that in cocos2d.

I would create a ‘Wagon’-class and then start by initiate two of them (just because I think that two wagons will fill the screen). And then start moving the wagons. Each time a wagon is completely out of the screen I would release it. When it’s time for the next wagon I would initiate that and so on.

How many frames does the animations have, and how big are they? Maybe you’ll have to make one atlas per wagon. You can always call:

[[CCTextureCache sharedTextureCache] removeUnusedTextures];

and:

[[CCSpriteFrameCache sharedSpriteFrameCache] removeUnusedSpriteFrames];
