Cocos2d 2.0 Animation

To do animation under cocos2d 2.0 you need to create sprite frame cache, sprite sheet, animation frames, animation, sprite, action, and start the animation.

Create Sprite Frame Cache

    [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"role.plist"];

Create Sprite Sheet

    CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"role.png"];

    [self addChild:spriteSheet];

Create Animation Frames

    NSMutableArray *danceAnimationFrames = [NSMutableArray array];

    for(int i=1; i <= 14; i++) {

        [danceAnimationFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"role%02d.png", i]]];

    }

Create Animation

    CCAnimation *danceAnimation = [CCAnimation animationWithSpriteFrames:danceAnimationFrames delay:0.1f];

Add Animation to Animation Cache

    [[CCAnimationCache sharedAnimationCache] addAnimation:danceAnimation name:@"danceAnimation"];

Get Animation from Animation Cache

    danceAnimation = [[CCAnimationCache sharedAnimationCache] animationByName:@"danceAnimation"];

Create Sprite

    self.role = [mySprite spriteWithSpriteFrameName:@"role01.png"];

Create Action

    self.danceAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:danceAnimation]];

Sample Code for AniEgg.h

#import "cocos2d.h"

#import "mySprite.h"

@interface AniEgg : CCLayer {

    mySprite *_role;

    CCAction *_danceAction;

}

+(CCScene *)scene;

@property (nonatomic, retain) mySprite *role;

@property (nonatomic, retain) CCAction *danceAction;

@end

Sample Code for AniEgg.m

#import "AniEgg.h"

BOOL paused;

int pausedCount;

@implementation AniEgg

@synthesize role = _role;

@synthesize danceAction = _danceAction;

+(CCScene *) scene {

    // 'scene' is an autorelease object.

    CCScene *scene = [CCScene node];

    // 'layer' is an autorelease object.

    AniEgg *layer = [AniEgg node];

    // add layer as a child to scene

    [scene addChild: layer];

    // return the scene

    return scene;

}

-(id) init {

    if( (self=[super init]) ) {

        [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"role.plist"];

        CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"role.png"];

        [self addChild:spriteSheet];

        NSMutableArray *danceAnimationFrames = [NSMutableArray array];

        for(int i=1; i <= 14; i++) {

            [danceAnimationFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"role%02d.png", i]]];

        }

        CCAnimation *danceAnimation = [CCAnimation animationWithSpriteFrames:danceAnimationFrames delay:0.1f];

        CGSize winSize = [[CCDirector sharedDirector] winSize];

        self.role = [mySprite spriteWithSpriteFrameName:@"role01.png"];

        _role.position = ccp(winSize.width / 2, winSize.height / 2);

        self.danceAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:danceAnimation]];

        [spriteSheet addChild:_role];

        [_role runAction:_danceAction];

        paused = NO;

        [self schedule:@selector(nextFrame:) interval:0.1f];

        self.isTouchEnabled = YES;

    }

    return self;

}

- (void) nextFrame:(ccTime)dt {

    if ([_role isTouched]) {

        if (paused) {

            paused = NO;

            [[[CCDirector sharedDirector] actionManager] resumeTarget:_role];

            pausedCount = 0;

        } else {

            paused = YES;

            [[[CCDirector sharedDirector] actionManager] pauseTarget:_role];

            pausedCount = 0;

        }

        [_role setUnTouched];

    }

    if (paused) {

        pausedCount++;

        if (pausedCount >= 20) {

            paused = NO;

            [[[CCDirector sharedDirector] actionManager] resumeTarget:_role];

            pausedCount = 0;            

        }

    }

}

- (void) dealloc

{

    self.role = nil;

    self.danceAction = nil;

}
