move

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

rotate

Rotation：
Rigidbody：MoveRotation

示例

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);
