用SpriteBuilder简化"耕牛遍地走"的动画效果(三)

NSMutableArray *walkAnimFrames = [NSMutableArray array];
for (int i = 1; i <= 8; i++) {
spriteFrame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
[NSString stringWithFormat:@"BearImagesHD/bear%d.png",i]];
[walkAnimFrames addObject:spriteFrame];
}

CCAnimation *walkAnim = [CCAnimation animationWithSpriteFrames:walkAnimFrames
delay:0.1f];
CGSize viewSize = [CCDirector sharedDirector].viewSize;
_bear = [CCSprite spriteWithImageNamed:@"BearImagesHD/bear1.png"];
_bear.position = ccp(viewSize.width/2,viewSize.height/2);
CCActionAnimate *animate = [CCActionAnimate actionWithAnimation:walkAnim];
_walkAction = [CCActionRepeatForever actionWithAction:animate];
[_bear runAction:_walkAction];
[sheet addChild:_bear];
