我用SpriteKit做了一场比赛，不同的砖块落在山上 . 当这些物理体落下时，它们通常从山上反弹并改变它们的排列（它们旋转几次） . 如果我转换到GameOver场景并按重放（回到GameScene），物理体仍然像我离开场景时那样对齐 . 但是我希望它们像开头一样进行水平对齐 .
GameScene：
import SpriteKit
import GameplayKit
let hillTexture = SKTexture(imageNamed: "HillIllustration")
let hillIllustration = SKSpriteNode(texture: hillTexture)
let brickTexture = SKTexture(imageNamed: "BrickIllustration")
let brick = SKSpriteNode(texture: brickTexture)
class GameScene: SKScene {
//Hill
hillIllustration.setScale(0.7)
hillIllustration.position = CGPoint(x: self.size.width / 2, y: self.size.height * 0.16)
hillIllustration.zPosition = 2
hillIllustration.physicsBody = SKPhysicsBody(polygonFrom: clipPath)
hillIllustration.physicsBody?.isDynamic = false
hillIllustration.physicsBody?.categoryBitMask = CollisionBitMask.Hill
hillIllustration.physicsBody?.affectedByGravity = false
self.addChild(hillIllustration)
//The brick is a child of the hill node
brick.setScale(1)
brick.position = CGPoint(x: -350, y: self.size.height * 0.5)
brick.zPosition = 1
brick.physicsBody = SKPhysicsBody(polygonFrom: clipPath2)
brick.physicsBody?.isDynamic = true
brick.physicsBody?.categoryBitMask = CollisionBitMask.Brick
brick.physicsBody?.affectedByGravity = true
hillIllustration.addChild(brick)
}
过渡到GameOver：
let transition = SKTransition.crossFade(withDuration: 0)
let gameScene = GameOver(size: self.size)
self.view?.presentScene(gameScene, transition: transition)
转回GameScene：
let transition = SKTransition.crossFade(withDuration: 0)
let gameScene = GameScene(size: self.size)
self.view?.presentScene(gameScene, transition: transition)
不知何故，当我转换场景时，砖块如何对齐的信息会被保存 . 我怎么能改变呢？

如果您在重新启动游戏后想要，那么砖块节点将返回开始旋转而不是调用：
如果你想在游戏过程中节点不旋转，你可以把这个代码放在已经存在于所有spritekit文件中的更新函数中：
希望这可以帮助
