Cocos2d iphone cocos2d子精灵与父精灵碰撞检测

嗨，我的社区

如何在cocos2d中检测子精灵与父精灵的碰撞

目前我的代码如下：

    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];

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

现在，我如何检测“跳线”和“平台”之间的碰撞

---

谢谢你的帮助

通常可以这样检查碰撞：

    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];

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

if（CGRectIntersectsRect（[jumper boundingBox]，[plat boundingBox]））{
//处理冲突

}

首先，为什么要在平台上初始化两次？你会发现内存泄漏。第二种方法是将已比较精灵的矩形坐标转换为世界坐标，然后进行比较
