在过去的两天里,我一直在努力获取两个SKSpriteNodes来注册冲突并唤起didBegin#contact
。
我已经为两个对象设置了它们的位掩码“categoryBitMask
”,“contactTestBitMask
”和“collisionTestBitMask
”。
我还将两个属性都设置为dynamic
。true
似乎可以建立PhysicsWorld了。
我只希望initPhysics()
被调用,但事实并非如此
//Set up Physicsbody bit masks
let playerCarBitMask: UInt32 = 0x1 << 1
let slowCarBitMask: UInt32 = 0x1 << 2
//initPhysics
func initPhysics() {
println("(((((((((((((( Initiating Physicsbody ))))))))))))))")
self.physicsWorld.contactDelegate = self
self.physicsWorld.gravity = CGVector.zeroVector
println("self.physicsWorld.contactDelegate = \(self.physicsWorld.contactDelegate)")
}
//setupPlayer
func setupPlayer() {
car = SKSpriteNode(imageNamed: "redCarUp")
car.setScale(2.0)
car.position = CGPoint(x: 800, y: 400)
car.zPosition = 100
car.name = "car"
gameNode.addChild(car)
let carBody = SKPhysicsBody(
rectangleOfSize: car.frame.size, center: car.position)
carBody.dynamic = true
carBody.categoryBitMask = playerCarBitMask
carBody.contactTestBitMask = slowCarBitMask
carBody.mass = 5
carBody.collisionBitMask = slowCarBitMask
car.physicsBody = carBody
println("carBody = \(carBody)")
println("carBody.dynamic = \(carBody.dynamic)")
println("carBody.mass = \(carBody.mass)")
println("carBody.categoryBitMask = \(carBody.categoryBitMask)")
println("carBody.contactTestBitMask = \(carBody.contactTestBitMask)")
println("carBody.collisionBitMask = \(carBody.contactTestBitMask)")
slowCar = SKSpriteNode(imageNamed: "blueCarUp")
slowCar.setScale(2.0)
let slowCarScenePos = CGPoint(
x: 680,
y: 2048)
slowCar.position = gameNode.convertPoint(slowCarScenePos, fromNode: self)
println("slowCar.position = \(slowCar.position) ****")
slowCar.zPosition = 80
slowCar.name = "slowCar"
let slowCarBody = SKPhysicsBody(
rectangleOfSize: slowCar.frame.size, center: slowCar.position)
println("slowCar = \(slowCar) ****")
slowCarBody.dynamic = true
slowCarBody.categoryBitMask = slowCarBitMask
slowCarBody.contactTestBitMask = playerCarBitMask
slowCarBody.mass = 5
slowCarBody.collisionBitMask = playerCarBitMask
slowCar.physicsBody = slowCarBody
gameNode.addChild(slowCar)
}
func didBeginContact(contact: SKPhysicsContact!) {
println("*******************PhysicsContact********************")
}
最佳答案
在Swift 3中,“didBeginContact”已更改为“didBegin”func didBegin(_ contact: SKPhysicsContact) { //stuff}
我有一个来自swift 2的代码,并且'didBeginContact'坐在那里,但是没有被调用。经过一番白色之后,我发现功能已更改。因此,我认为我的回答可以帮助某人。
