如何在SpriteKit中跳转后使播放器节点站立？

Question

我根据纹理为玩家（兽人）创建了一个物理物体。

player.physicsBody = SKPhysicsBody(texture: player.texture!, size: player.texture!.size())
player.physicsBody?.isDynamic = true
player.physicsBody?.usesPreciseCollisionDetection = true
player.physicsBody?.categoryBitMask = CollisionCategoryBitmask.Player
player.physicsBody?.collisionBitMask = 1
player.physicsBody?.restitution = 0
player.physicsBody?.friction = 1
ground?.physicsBody?.restitution = 0

并且通过施加冲动来创建跳跃动作

 func jumpPlayer(){
    player.physicsBody?.applyImpulse(CGVector(dx: 0, dy: 60))
 }

跳跃后，一旦降落，玩家节点似乎失去平衡并掉落。

如何避免这种情况？

Answer 1

可以通过将allowRotation设置为false来解决此问题

player.physicsBody?.allowsRotation = false
