cocos2d子精灵与父精灵的碰撞检测 [英] cocos2d Children sprite collision detection with parent sprite

问题描述

您好，stackoverflow社区！

如何在cocos2d中检测到与子精灵碰撞的子sprite碰撞？

目前我有这样的代码：

  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]; 
  

现在如何检测 jumper

解决方案

通常你可以这样检查冲突：

  if（CGRectIntersectsRect（[jumper boundingBox]，[plat boundingBox ]））{
 //处理碰撞< br> 
} 
  

Hi stackoverflow community!

How do you detect a children sprite collision with a parent sprite in cocos2d?

Currently I have my codes like this:

    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];

Now how do I detect the collision between "jumper" & "plat"?

Thanks for your help!

解决方案

Usually you can check collision like this:

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