Question

我正试图防止我的精灵旋转。我看过其他一些StackOverflow答案，但没有任何帮助。当我将精灵移动到另一个节点或紧靠物理边界一侧时，它将旋转它。

这是我初始化精灵时尝试过的：

        let texture = SKTexture(imageNamed:character.image)
        let size = CGSize(width: character.width, height: character.height)
        player = playerNode
        player.name = "player"
        player.physicsBody?.isDynamic = true
        player.physicsBody?.allowsRotation = false
        player.physicsBody?.angularVelocity = 1
        player.texture = texture
        player.position = CGPoint(x:0, y:0)
        player.size = size

        // Physics
        player.physicsBody?.categoryBitMask = BodyType.player.rawValue
        player.physicsBody?.contactTestBitMask = BodyType.dot.rawValue
        player.physicsBody?.collisionBitMask = 0
        player.physicsBody = SKPhysicsBody(texture: texture, size: size)
        player.physicsBody?.linearDamping = 1
        player.physicsBody?.angularDamping = 1

在您进入“物理学”部分的这一行之前，您的player实际上没有物理学实体：

player.physicsBody = SKPhysicsBody(texture: texture, size: size)

因此所有这些用于设置物理实体属性的行都无济于事：

    player.physicsBody?.isDynamic = true
    player.physicsBody?.allowsRotation = false
    player.physicsBody?.angularVelocity = 1

    // Physics
    player.physicsBody?.categoryBitMask = BodyType.player.rawValue
    player.physicsBody?.contactTestBitMask = BodyType.dot.rawValue
    player.physicsBody?.collisionBitMask = 0

将物理实体的创建移至“物理”部分的顶部，然后将其分配给所有物理实体。
