我尝试创建位掩码类别,将所有恢复值设置为 1 以及阳光下的所有其他内容,包括在设备上运行应用程序,但它仍然无法正常工作。在设置一个 SKSpriteNode 与 retitution 1 以在 dx: 100 处击中另一个 skspritenode 后,它仍然没有反弹!这是我的 GameScene.swift 代码:
import SpriteKit
import GameplayKit
class GameScene: SKScene {
override func didMove(to view: SKView) {
let Ball = SKSpriteNode()
Ball.self.childNode(withName: "Ball")
let playerPaddle = SKSpriteNode()
playerPaddle.self.childNode(withName: "playerPaddle")
let computerPaddle = SKSpriteNode()
computerPaddle.self.childNode(withName: "computerPaddle")
let ballCategory: UInt32 = 0x1 << 1
let paddleCategory: UInt32 = 0x1 << 2
let borderCategory: UInt32 = 0x1 << 3
Ball.physicsBody?.categoryBitMask = ballCategory
playerPaddle.physicsBody?.categoryBitMask = paddleCategory
computerPaddle.physicsBody?.categoryBitMask = paddleCategory
self.physicsBody?.categoryBitMask = borderCategory
let playerScore = SKLabelNode()
playerScore.fontName = "Pong Score"
playerScore.text = "0"
playerScore.fontSize = 100
playerScore.color = SKColor.white
playerScore.position = CGPoint(x: -200, y: 220)
playerScore.zPosition = 3
addChild(playerScore)
let comScore = SKLabelNode()
comScore.fontName = "Pong Score"
comScore.text = "0"
comScore.fontSize = 100
comScore.color = SKColor.white
comScore.position = CGPoint(x: 200, y: 220)
comScore.zPosition = 3
addChild(comScore)
var comScoreInt: Int = Int(comScore.text!)!
comScoreInt += 1
comScore.text = String(comScoreInt)
var playerScoreInt: Int = Int(playerScore.text!)!
playerScoreInt += 1
playerScore.text = String(playerScoreInt)
let bodyBorder = SKPhysicsBody(edgeLoopFrom: self.frame)
bodyBorder.friction = 0
bodyBorder.restitution = 1
self.physicsBody = bodyBorder
}
}
PS 大部分物理都在 GameScene.sks 而不是 GameScene.swift 中,但这是位掩码所在的位置。
