我是使用SpriteKit /
Swift进行编码的新手,并且存在以下问题:
一个角色应该通过跳入它们来收集硬币.在检测碰撞和摆脱收集的硬币时没有问题,但是我的角色在硬币消失之前会反弹.

角色应该通过硬币飞行并在途中收集它.
let playerCategory: UInt32 = 0x1 << 0 let coinCategory: UInt32 = 0x1 << 1
player = SKSpriteNode(texture: playerTexture) player.physicsBody = SKPhysicsBody(circleOfRadius: player.size.height / 2) player.physicsBody?.dynamic = true player.physicsBody?.allowsRotation = false player.physicsBody?.categoryBitMask = playerCategory player.physicsBody?.contactTestBitMask = coinCategory var coin:SKSpriteNode = SKSpriteNode(texture: coinTexture) coin.physicsBody = SKPhysicsBody(circleOfRadius: coin.size.height / 2) coin.physicsBody?.dynamic = false coin.physicsBody?.allowsRotation = false coin.physicsBody?.categoryBitMask = coinCategory coin.physicsBody?.contactTestBitMask = playerCategory
func playerDidCollideWithCoin(player:SKSpriteNode,thisCoin:SKSpriteNode) { thisCoin.removeFromParent() coinsCollected++ }
碰撞检测工作正常,但正如我所说,我怎样才能避免撞击并用“飞越”代替?
我正在使用Xcode 6 Beta 7
提前致谢!
解决方法
spritekit的默认行为是,除非碰撞位掩码更改为0,否则所有内容都会与所有内容发生冲突.
在您不希望退回但接收来自它们的通知的所有对象中,将代码中的此值更改为0.
player = SKSpriteNode(texture: playerTexture) player.physicsBody = SKPhysicsBody(circleOfRadius: player.size.height / 2) player.physicsBody?.dynamic = true player.physicsBody?.allowsRotation = false player.physicsBody?.categoryBitMask = playerCategory player.physicsBody?.contactTestBitMask = coinCategory player.physicsBody?.collisionBitMask = 0 var coin:SKSpriteNode = SKSpriteNode(texture: coinTexture) coin.physicsBody = SKPhysicsBody(circleOfRadius: coin.size.height / 2) coin.physicsBody?.dynamic = false coin.physicsBody?.allowsRotation = false coin.physicsBody?.categoryBitMask = coinCategory coin.physicsBody?.contactTestBitMask = playerCategory coin.physicsBody?.collisionBitMask = 0
这将阻止这些对象相互反弹.
