[游戏开发]unity相机视口自适应

开始上班了，写一下上班后的第一篇博客，关于unity相机视口自适应，16:9

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CameraRectFix : MonoBehaviour
{
    private Camera _camera;
    private float _aspect;
    private float _nowHeight;
    private float _nowWidth;
    private float _designAspect;
    private float _nowH;
    private float _nowW;
    private float _screenHeight;
    private float _screenWidth;
    void Start()
    {
        _screenHeight = Screen.height;
        _screenWidth = Screen.width;
        _camera = GetComponent<Camera>();
        _designAspect = 16f / 9f;
        FixRect();
    }
    void CheckWindow()
    {
        if (_screenWidth != Screen.width||_screenHeight!=Screen.height)
        {
            Debug.Log("重设视口");
            _screenWidth = Screen.width;
            _screenHeight = Screen.height;
            FixRect();
        }
    }

    // Update is called once per frame
    void Update()
    {
        CheckWindow();
    }
    public void FixRect()
    {
        _aspect = _screenWidth / _screenHeight;
        if (_aspect>_designAspect)
        {
            _nowWidth = Screen.height * _designAspect;
            _nowW = _nowWidth / Screen.width;
            _camera.rect = new Rect((1-_nowW)/2f, 0f, _nowW,1f);
        }
        else
        {
            //以宽为基准
            _nowHeight = Screen.width / _designAspect;
            _nowH = _nowHeight / Screen.height;
            _camera.rect = new Rect(0f, (1 - _nowH) / 2f, 1f,_nowH);
        }
    }

}

就这些
