Swift SpriteKit - 防止精灵节点角旋转

Question

我试图阻止我的精灵旋转。我看过其他一些StackOverflow的答案，但没有任何帮助。当我将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实际上没有物理主体，直到你到达"物理"部分的这一行：

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

因此，所有这些在物理体上设置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"物理"部分的顶部，然后将所有物理体的属性赋值移到"物理"部分的顶部。
