移动旋转

简介

简单总结

---

move

• CharacterController：
• Rigidbody：AddForce，MovePosition
• Translate：不检测碰撞

---

rotate

• Rotation：
• Rigidbody：MoveRotation

示例

1. 王者荣耀式：

   using System.Collections;
   using System.Collections.Generic;
   using UnityEngine;
   
   public class PlayerCtrl : MonoBehaviour
   {
       public float speedmove = 1;
       public float speedrot = 20;
   
       private CharacterController cc;
       private float ver;
       private float hor;
       private Vector3 dir;
       private Quaternion qua;
   
       private void Start()
       {
           cc = GetComponent<CharacterController>();
       }
   
       private void Update()
       {
   
       }
   
       private void FixedUpdate()
       {
           hor = Input.GetAxis("Horizontal");
           ver = Input.GetAxis("Vertical");
           dir = new Vector3(hor, 0, ver).normalized;
           cc.SimpleMove(dir * speedmove);
           //transform.position = Vector3.Lerp(transform.position,transform.position+dir, Time.deltaTime * speedmove);
           if (hor != 0 || ver != 0)
           {
               qua = Quaternion.LookRotation(dir);
               transform.rotation = Quaternion.Lerp(transform.rotation, qua, Time.deltaTime * speedrot);
           }
       }
   }

        Vector3.Angle(Vector3,Vector3);                //向量夹角
        Vector3.ClampMagnitude(Vector3, maxLength);    //复制一个向量，指定最大长度

        //差乘(右手大拇指确定方向)
        Vector3.Cross(Vector3,Vector3);                

        Vector3.Distance(Vector3, Vector3);            //距离
        Vector3.Dot(Vector3, Vector3);                 //点乘
        Vector3.Project(Vector3, Vector3);             //投影
        Vector3.Reflect(Vector3, Vector3);             //反射向量

        Quaternion.Angle(a, b);                     //夹角
        Quaternion.AngleAxis(angle, axis);          //绕轴转角度
        Quaternion.Dot(a, b);                       
        Quaternion.Euler(euler);
        Quaternion.FromToRotation(from, to);        
        Quaternion.Inverse(a);                      //反向
        Quaternion.LookRotation(v3);                //看向
        Quaternion.RotateTowards(from, to, angle);  //转向
        Quaternion.Slerp(a, b, t);  

注意：

    LookRotation：

看向一个向量，是一个方向

    LookAt：

看向一个坐标，一个点
