cocoa-touch – 在数组cocos2d`中获取精灵的位置

我需要能够触摸数组中的特定移动精灵并对其执行操作.但是,当我执行Moveto操作时,精灵位置不会更新.救命！

阵：

int numbreds = 7;

redBirds = [[CCArray alloc] initWithCapacity: numbreds];

for( int i = 1; i<=numbreds; i++){

    int xvalue = ((-50*i) + 320);
    int yvalue= 160;


    if (i==4)
    { 
        CCSprite *parrot = [CCSprite spriteWithFile:@"taco.png"];

        [birdLayer addChild:parrot];
        [self movement]; //the action that moves the array horizontally
        parrot.position = ccp(xvalue,yvalue);
        parrot.tag=100;

触摸

-(void)cctouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView:[touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];


CCSprite *mark = (CCSprite *)[birdLayer getChildByTag:100];

if (CGRectContainsPoint([mark boundingBox],location))
{

    cclOG(@"YAY!");
}

问题是CCSprite的位置实际上没有更新或移动.好极了！仅在精灵的原点位置生成.

解决方法

试试这个：

CCSprite *temp = [CCSprite spriteWithFile:@"taco.png"];

temp = [birdLayer getChildByTag:100];

if (temp.position.x == location.x) {

    // do stuff...
}
