cocos2d 总结：三 CCSprite
CCSprite
?
1: CCSpriteBatchNode?? ???????(可能是多个CCSprite)
?
CCSpriteBatchNode* batch = [CCSpriteBatchNode batchNodeWithFile:@"bullet.png"];
?
CCArray* bullets = [batch? children];
?
2:用多个单独的文件创建动画 CCAnimation, CCSpriteFrame
?
?
+(CCAnimation*) animationWithFile:(NSString*)name frameCount:(int)frameCount delay:(float)delay
{
??? // load the animation frames as textures and create the sprite frames
??? NSMutableArray* frames = [NSMutableArray arrayWithCapacity:frameCount];
??? for (int i = 0; i < frameCount; i++)
??? {
?????? // Assuming all animation files are named "nameX.png" with X being a consecutive number starting with 0.
?????? NSString* file = [NSString stringWithFormat:@"%@%i.png", name, i];
?????? CCTexture2D* texture = [[CCTextureCache sharedTextureCache] addImage:file];
?
?????? // Assuming that image file animations always use the whole image for each animation frame.
?????? CGSize texSize = texture.contentSize;
?????? CGRect texRect = CGRectMake(0, 0, texSize.width, texSize.height);
?????? CCSpriteFrame* frame = [CCSpriteFrame frameWithTexture:texture rect:texRect offset:CGPointZero];
??????
?????? [frames addObject:frame];
??? }
???
??? // create an animation object from all the sprite animation frames
??? return [CCAnimation animationWithName:name delay:delay frames:frames];
}
?
//调用方式
CCAnimate* animate = [CCAnimate
actionWithAnimation:[self animationWithFile:@"ship-anim" //图片文件
frameCount:5 //帧数
delay:0.08f]//持续时间
];
?
3:从*.plist 文件创建动画
?
1）// Creates an animation from single files.
?
?
-(id) initWithShipImage
{
??? // Load the Texture Atlas sprite frames, this also loads the Texture with the same name.
??? CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache];
??? [frameCache addSpriteFramesWithFile:@"ship-and-bullet.plist"];
?
??? // Loading the Ship's sprite using a sprite frame name (eg the filename)
??? if ((self = [super initWithSpriteFrameName:@"ship.png"]))
??? {
?????? // load the ship's animation frames as textures and create a sprite frame
?????? NSMutableArray* frames = [NSMutableArray arrayWithCapacity:5];
?????? for (int i = 0; i < 5; i++)
?????? {
?????????? NSString* file = [NSString stringWithFormat:@"ship-anim%i.png", i];
?????????? CCSpriteFrame* frame = [frameCache spriteFrameByName:file];
?????????? [frames addObject:frame];
?????? }
??????
?????? // create an animation object from all the sprite animation frames
?????? CCAnimation* anim = [CCAnimation animationWithName:@"move" delay:0.08f frames:frames];
??????
?????? // add the animation to the sprite (optional)
?????? //[self addAnimation:anim];
??????
?????? // run the animation by using the CCAnimate action
?????? CCAnimate* animate = [CCAnimate actionWithAnimation:anim];
?????? CCRepeatForever* repeat = [CCRepeatForever actionWithAction:animate];
??? ?? [self runAction:repeat];
??????
??????
?????? [self scheduleUpdate];
??? }
??? return self;
}
?
// Creates an animation from single files.
+(CCAnimation*) animationWithFile:(NSString*)name frameCount:(int)frameCount delay:(float)delay
{
??? // load the animation frames as textures and create the sprite frames
??? NSMutableArray* frames = [NSMutableArray arrayWithCapacity:frameCount];
??? for (int i = 0; i < frameCount; i++)
??? {
?????? // Assuming all animation files are named "nameX.png" with X being a consecutive number starting with 0.
?????? NSString* file = [NSString stringWithFormat:@"%@%i.png", name, i];
?????? CCTexture2D* texture = [[CCTextureCache sharedTextureCache] addImage:file];
?
?????? // Assuming that image file animations always use the whole image for each animation frame.
?????? CGSize texSize = texture.contentSize;
?????? CGRect texRect = CGRectMake(0, 0, texSize.width, texSize.height);
?????? CCSpriteFrame* frame = [CCSpriteFrame frameWithTexture:texture rect:texRect offset:CGPointZero];
??????
?????? [frames addObject:frame];
??? }
???
??? // create an animation object from all the sprite animation frames
??? return [CCAnimation animationWithName:name delay:delay frames:frames];
}
?
?
2) Creates an animation from sprite frames.
?
-(id) initWithShipImage
{
??? // Load the Texture Atlas sprite frames, this also loads the Texture with the same name.
??? CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache];
??? [frameCache addSpriteFramesWithFile:@"ship-and-bullet.plist"];
?
??? // Loading the Ship's sprite using a sprite frame name (eg the filename)
??? if ((self = [super initWithSpriteFrameName:@"ship.png"]))
??? {
?????? // create an animation object from all the sprite animation frames
?????? CCAnimation* anim = [CCAnimation animationWithFrame:@"ship-anim" frameCount:5 delay:0.08f];
??????
?????? // add the animation to the sprite (optional)
?????? //[self addAnimation:anim];
??????
?????? // run the animation by using the CCAnimate action
?????? CCAnimate* animate = [CCAnimate actionWithAnimation:anim];
?????? CCRepeatForever* repeat = [CCRepeatForever actionWithAction:animate];
?????? [self runAction:repeat];
??????
??????
?????? [self scheduleUpdate];
??? }
??? return self;
}
?
?
// Creates an animation from sprite frames.
+(CCAnimation*) animationWithFrame:(NSString*)frame frameCount:(int)frameCount delay:(float)delay
{
??? // load the ship's animation frames as textures and create a sprite frame
??? NSMutableArray* frames = [NSMutableArray arrayWithCapacity:frameCount];
??? for (int i = 0;
