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 / div>
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>
}
