CCSprite重叠在一起

Question

-(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
 {

     _nextProjectile = [[CCSprite spriteWithFile:@"arrow.png"]retain];
     _nextProjectile.position = imgArrow.position;

        [imgArrow runAction:[CCSequence actions:
                            [CCRotateTo actionWithDuration:rotateDuration angle:cocosAngle],
                            [CCCallFunc actionWithTarget:self selector:@selector(finishShoot)],
                            nil]];
    //Some code 

    }

- (void)finishShoot {

    // Ok to add now - we've finished rotation!

    [self addChild:_nextProjectile];
    [_projectiles addObject:_nextProjectile];

    // Release
    [_nextProjectile release];
    _nextProjectile = nil;
}

当我点击弓箭两次时，我的箭头与另一个箭头重叠。

任何帮助？！

Answer 1

在释放下一个箭头并触摸之前，您需要删除之前的箭头。我认为你正在制作一个射击游戏，当触摸屏幕时会释放箭头。我建议在动作完成时删除最后一个箭头

Answer 2

尝试使用此代码，在添加之前我们已经删除了箭头，（如果有的话，修复语法错误）

-(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
 {
 [self removeChild:[self childWithTag:101]];
 _nextProjectile = [[CCSprite spriteWithFile:@"arrow.png"]retain];
 _nextProjectile.tag = 101;
 _nextProjectile.position = imgArrow.position;

    [imgArrow runAction:[CCSequence actions:
                        [CCRotateTo actionWithDuration:rotateDuration angle:cocosAngle],
                        [CCCallFunc actionWithTarget:self selector:@selector(finishShoot)],
                        nil]];
//Some code 

}
