Unity中实现鼠标拖动人物旋转

gif效果图如下：

以下脚本直接挂载在需要转动的人物身上即可。 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerRotate : MonoBehaviour
{
    private float x_axle = 0;
    private float y_axle = 0;
    private void RotateObj()
    {
        if (Input.GetMouseButton(0))
        {
            x_axle = Input.GetAxis("Mouse X");
            y_axle = Input.GetAxis("Mouse Y");
        }
        if (x_axle > 0)
        {
            x_axle -= Time.deltaTime;
            if (x_axle < 0)
                x_axle = 0;
        }
        else
        {
            x_axle += Time.deltaTime;
            if (x_axle > 0)
                x_axle = 0;
        }
        if (y_axle > 0)
        {
            y_axle -= Time.deltaTime;
            if (y_axle < 0)
                y_axle = 0;
        }
        else
        {
            y_axle += Time.deltaTime;
            if (y_axle > 0)
                y_axle = 0;
        }
        gameObject.transform.Rotate(0, x_axle * -10, 0);
        gameObject.transform.Rotate(0, y_axle * -10, 0);
    }
    void Update()
    {
        RotateObj();
    }
}
