旋转时SKSpritenode旋转太快

Question

当前，当触摸屏幕的一侧时，我试图将SKSpritenode旋转到45度，而当另一侧触摸另一侧时-45度，当触摸结束时返回到零。问题在于，它不是从-45到0或-45到45的最快途径，而是多次旋转相反的方向，直到达到该学位。这是我当前的代码：

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
            if let touch = touches.first {
                let location = touch.previousLocation(in: self)
                let position = touch.location(in: self)
                let node = self.nodes(at: location).first


//IF LEFT SCREEN IS TOUCHED
if position.x < 0 {
    let rotate = CGFloat(45.0 * .pi / 180)
    let rotateAction =  SKAction.rotate(toAngle: rotate, duration: 0.2)
    car.run(rotateAction, withKey: "rotating")
         
    

//IF RIGHT SCREEN IS TOUCHED
            } else {
                let rotate2 = CGFloat(-45.0 * .pi / 180)
                let rotateAction2 =  SKAction.rotate(toAngle: rotate2, duration: 0.2)
                car.run(rotateAction2, withKey: "rotating")
                     
         
                }
            
        }
            
    }





 override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {

     car.removeAction(forKey: "rotating")
     
         let rotate4 = CGFloat(0.0 * .pi / 180)
         let rotateAction4 =  SKAction.rotate(toAngle: rotate4, duration: 0.2)
     car.run(rotateAction4, withKey: "rotating4")
         
        }

Answer 1

添加一个shortestunitarc：true参数：

let rotateAction = SKAction.rotate(toAngle: rotate, duration: 0.2, shortestUnitArc: true)

请注意，rotate：

• rotate（toangle：duration：）
• 旋转（toangle：toangle：shortestunitarc：）
• 旋转（byangle：持续时间：）
