我期待这段代码删除精灵,但它不起作用。精灵仍然在屏幕上。我在这里做错了,请帮忙。感谢。
编辑:
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"vase.plist"];
CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"vase.png"];
[self addChild:spriteSheet z:1 tag:1];
//CCSpriteFrame must be created for each animation frame.
NSMutableArray *animFrames = [NSMutableArray array];
for (int i = 1; i <= 3; i++) {
NSString *file = [NSString stringWithFormat:@"frame %d.png", i];
CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:file];
[animFrames addObject:frame];
}
//Sprite is positioned and then animated.
CCSprite *player = [CCSprite spriteWithSpriteFrameName:@"frame 1.png"];
CCAnimation *anim = [CCAnimation animationWithFrames:animFrames delay:0.20f];
CCRepeat *repeat = [CCRepeat actionWithAction:[CCAnimate actionWithAnimation:anim restoreOriginalFrame:YES] times:3];
[player runAction:repeat];
player.position = startPostion;
[spriteSheet addChild:player];
答案 0 :(得分:4)
Ure正在从self
删除精灵,但精灵不是self
的孩子。这是spriteSheet
的孩子,因为你写过:
[spriteSheet addChild:player];
所以你必须从spriteSheet
而不是self中删除精灵。但它更容易:
[sprite removeFromParentAndCleanup: YES];
