Animate a Sprite in Cocos2D

Animate a Sprite in Cocos2D

February 26, 2014

The old way

Creating an animation for a CCSprite can be a repetitive task. Mostly you will create a CCSprite subclass for each animated object in your game. If you have lots of animations you will end up with a lot of boilerplate-code looking somewhat similar to this:

[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: @"animation_knight.plist"];
// ************* RUNNING ANIMATION ********************
animationFramesRun = [NSMutableArray array];
for(int i = 1; i <= 4; ++i)
    [animationFramesRun addObject:
        [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: [NSString stringWithFormat:@"animation_knight-%d.png", i]]];
//Create an animation from the set of frames you created earlier
CCAnimation *running = [CCAnimation animationWithSpriteFrames: animationFramesRun delay:0.1f];
//Create an action with the animation that can then be assigned to a sprite
run = [CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:running]];

You load a Spritesheet to the CCSpriteFrameCache, you add the single images to an array from which you generate a CCAnimation action. Finally you wrap the CCAnimation action into a CCRepeatForever action and run it. And you write this code for every single animation in your game.

Using CCAnimatedSprite

CCAnimatedSprite is here to help - and eliminate all that duplicate code from your game.

Here is how to use it:

// 1.) initialize a CCAnimatedSprite with a Plist that contains your animation frames (generated by Zwoptex or Texture Packer
CCAnimatedSprite *animatedSprite = [CCAnimatedSprite animatedSpriteWithPlist:@"animation_knight.plist"];
// 2.) create an animation (use the animation name, that is used for the frames in your Spritesheet)
[animatedSprite addAnimationwithDelayBetweenFrames:0.1f name:@"animation_knight"];
// 3.) run the animation, referring it by name
[animatedSprite runAnimation:@"animation_knight"];

You only have to be aware of using the same name as you used in your plist for the frame names. If your animation is called animation_knight your frames in the .plist need to be called animation_knight-1.png, animation_knight-2.png and so forth:
