将Cinemachine的freelook改为鼠标右键控制转向

用CM给的案例来测试，直接把下边的代码挂到CM摄像机上，代码来自上边的链接

（这个链接有手机端的代码，目前我还没涉及到，先马着）

 

 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Cinemachine;
 
public class CMFreelookOnlyWhenRightMouseDown : MonoBehaviour {
    void Start(){
        CinemachineCore.GetInputAxis = GetAxisCustom;
    }
    public float GetAxisCustom(string axisName){
        if(axisName == "Mouse X"){
            if (Input.GetMouseButton(1)){
                return UnityEngine.Input.GetAxis("Mouse X");
            } else{
                return 0;
            }
        }
        else if (axisName == "Mouse Y"){
            if (Input.GetMouseButton(1)){
                return UnityEngine.Input.GetAxis("Mouse Y");
            } else{
                return 0;
            }
        }
        return 0;
    }
}
