physicsBody = SKPhysicsBody(edgeLoopF​​romRect: view.frame)

Question

尝试使用 edgeLoopF​​romRect 使我的 SKSpriteNode 停留在仅纵向布局的框架内：view.frame，并且它仅从框架的左侧反弹并且仍然留下间隙....

尝试使用 "view"，edgeLoopF​​romRect: frame，它飞出了屏幕...

任何帮助将不胜感激..

func makeShip() {
    let ship = playerShip
    ship.position = CGPoint(x: frame.size.width / 2, y: frame.size.height / 2)
    ship.physicsBody = SKPhysicsBody(rectangleOfSize: ship.frame.size)
    ship.physicsBody!.dynamic = true
    ship.physicsBody!.affectedByGravity = false
    ship.physicsBody!.mass = 0.08
    addChild(ship)
}


override func didMoveToView(view: SKView) {

    makeShip()
    physicsBody = SKPhysicsBody(edgeLoopFromRect: view.frame)
    motionManager.startAccelerometerUpdates()
}

Answer 1

在 override func didMoveToView(view: SKView) 中尝试添加：

let borderBody = SKPhysicsBody(edgeLoopFromRect: self.frame)
borderBody.friction = 0
self.physicsBody = borderBody
