我需要能够触摸数组中的特定移动 Sprite 并对其执行操作。但是,当我执行 MoveTo 操作时, Sprite 位置不会更新。救命!
数组:
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!");
}
问题在于 CCSprite 的位置实际上并未更新或移动。耶!仅在 Sprite 的原点位置生成。
最佳答案
试试这个:
CCSprite *temp = [CCSprite spriteWithFile:@"taco.png"];
temp = [birdLayer getChildByTag:100];
if (temp.position.x == location.x) {
// do stuff...
}
