unity3d 物体移动逐渐变慢

Question

物体正常移动，然后按键让物体移动速度逐渐变慢

Answer 1

设定一个速度值speed，按键时，减少speed的值，这是最简单的做法了。public float Speed = 1.0f;public float AddSpeed = 0.1f;void Start (){}void Update (){if (Input.GetKey(KeyCode.W))Speed += AddSpeed;if (Input.GetKey(KeyCode.S))Speed -= AddSpeed;Speed = Mathf.Clamp(Speed,0,Speed);transform.Translate(Vector3.forward*Time.deltaTime*Speed);}
