状态机中的人物状态

一，人物惯性移动

using System.Collections; using System.Collections.Generic; using UnityEngine; public class CharMove3 : MonoBehaviour { public Transform charTrans; //角色坐标 public Vector3 currentVelocity; //当前速度 public float maxSpeed; //最大速率 public float turnSpeed; //转向速率 public float acceleration; //加速度 public float deceleration; //衰减速度 void Update() { float horizontal = Input.GetAxis("Horizontal"); //AD float vertical = Input.GetAxis("Vertical"); //WS Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized; if (direction.sqrMagnitude > 0) //如果有输入 { //算当前速度在目标方向上的投影 float directionSpeed = Vector3.Dot(direction, currentVelocity); //惯性速度 Vector3 remainSpeed = currentVelocity - directionSpeed * direction; //加速 directionSpeed += acceleration * Time.deltaTime; //限速 directionSpeed = Mathf.Clamp(directionSpeed, -maxSpeed, maxSpeed); //转向速度减速 remainSpeed = Vector3.MoveTowards(remainSpeed, Vector3.zero, turnSpeed * Time.deltaTime); currentVelocity = directionSpeed * direction + remainSpeed; } else { currentVelocity = Vector3.MoveTowards(currentVelocity,Vector3.zero,deceleration * Time.deltaTime); } charTrans.position += currentVelocity*Time.deltaTime; } }

二，人物刹车
