解决！

获取sprite框架的坐标使用sprite.boundingBox.origin.x;

您好！
我正在实现一个简单的代码，但我无法理解它的行为：

anewSprite = [CCSprite spriteWithFile:@"grossini.png"];
anewSprite.position = ccp(80, 80);
[self addChild:anewSprite];


anotherSprite = [CCSprite spriteWithFile:@"grossini.png"];
anotherSprite.position = ccp(300, 80);
[self addChild:anotherSprite];



-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{
    CGPoint point= [touch locationInView:[touch view]];
    point = [[CCDirector sharedDirector] convertToGL: point];

    NSLog(@"point x:%f y:%f", point.x, point.y);
    if (CGRectContainsPoint(anewSprite.textureRect, point)){
        NSLog(@"contains point");
    } else {
        NSLog(@"does not contain");
    }
    return  TRUE;
}



-(void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event{
    CGPoint point= [touch locationInView:[touch view]];
    point = [[CCDirector sharedDirector] convertToGL: point];

    anewSprite.position = point;
    if (CGRectContainsRect(anewSprite.textureRect, anotherSprite.textureRect) == TRUE) {
        NSLog(@"Intersects");
    }
}

问题在于：

NSLog(@"anotherSpriteTextureRectOrigin X:%f Y:%f", enemy1.textureRect.origin.x, enemy1.textureRect.origin.y);
NSLog(@"anewSpriteTextureRectOrigin X:%f Y:%f", anewSprite.textureRect.origin.x, anewSprite.textureRect.origin.y);

显示：
anotherSpriteTextureRectOrigin X：0.000000 Y：0.000000
anewSpriteTextureRectOrigin X：0.000000 Y：0.000000

提前致谢！

要检查一个sprite是否与另一个sprite相交，而不是sprite.frame.rect，请使用sprite.boundingBox

例如：

if (CGRectContainsRect(sprite1.boundingBox, sprite2.boundingBox)) {
     NSLog(@"Contains");
}

cocos2d CCSprite没有得到坐标
