Swift SpriteKit - 防止 sprite 节点 angular 旋转

Question

我试图阻止我的精灵旋转。我看过其他一些 Whosebug 答案，但没有任何帮助。当我将我的精灵移动到另一个节点或物理边界的一侧时，它会旋转它。

这是我在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

Answer 1

你的 player 实际上没有物理体，直到你到达 'physics' 部分的这一行：

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

所以所有这些用于设置物理体属性的行都没有做任何事情：

    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

将物理体的创建移到 'physics' 部分的顶部，然后是所有物理体的属性赋值。
