我一直在努力爭取在過去兩天得到兩個SKSpriteNodes來註冊衝突並喚起didBegin#contact
。iOS Swift didBeginContact未被調用
我已經爲這兩個對象設置了位掩碼'categoryBitMask
','contactTestBitMask
'和'collisionTestBitMask
'。
我還設置了「dynamic
」屬性都爲「true
」
initPhysics()
似乎建立physicsWorld還好。
所有我期待的是,didBegin#Contact
被調用,但它不是
//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********************")
}
代碼轉儲不在此平臺上讚賞。 – Mundi 2014-10-18 10:37:50
注意**以及collisionBitMask,你必須設置contactTestBitMask **。這是通常的gotchya。請注意,在故事板編輯器中,它將contactTestBitMask保留爲默認值0--這是通常的問題。只需將其設置爲「1」 – Fattie 2017-10-23 21:35:28
