如何在SpriteKit中让玩家节点在跳转后站立？

Question

我根据纹理为玩家(兽人)创建了一个物理实体。

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

​

​

跳跃动作是通过施加脉冲来创建的

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

跳跃后，一旦落地，球员节点似乎失去了平衡并倒下。

​

我怎样才能避免这种情况？

Answer 1

这可以通过将allowsRotation设置为false来修复

player.physicsBody?.allowsRotation = false
