Question

unity3d 物体移动逐渐变慢

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);
}
