cocos2d子镜头与父精灵的sprite碰撞检测

Question

您好stackoverflow社区！

如何在cocos2d中检测与父级精灵的子级精灵碰撞？

目前我的代码是这样的：

    CGSize screenSize = [[CCDirector sharedDirector]winSize];

    parentJumper = [CCSprite spriteWithFile:@"inviBtn.png"];
    jumper = [CCSprite spriteWithFile:@"jumperRight.png"];

    plat = [[Platform alloc]init];

    plat = [Platform spriteWithFile:@"platformBlack.png"];

    plat.position = ccp(160,100);

    [[UIAccelerometer sharedAccelerometer] setUpdateInterval:(1.0/60)];

    jumper.anchorPoint = ccp(0.5, 0);
    jumper.position = ccp(0, 20);
    parentJumper.position = ccp(screenSize.width/2, 0);

    [self addChild:plat];
    [self addChild:parentJumper];
    [parentJumper addChild:jumper];

现在我如何检测“跳线”＆amp; “的高原”

感谢您的帮助！

通常你可以像这样检查碰撞：

if(CGRectIntersectsRect([jumper boundingBox], [plat boundingBox])) {
  //Handle collision<br>
}
