Unity宽度适配的代码

将该代码附加到camera上,devHeight和devWidth修改为设计分辨率

using UnityEngine;
public class GameCamera : MonoBehaviour
{
    float devHeight = 1920f;
    float devWidth = 1080f;

    void Start()
    {
        float orthographicSize = this.GetComponent<Camera>().orthographicSize;
        orthographicSize = orthographicSize / (devHeight / devWidth) * (Screen.height * 1.0f / Screen.width);
        this.GetComponent<Camera>().orthographicSize = orthographicSize;
    }
}

摄像机尺寸Size除以设计时的高宽比,再乘以实际屏幕高宽比,得到同宽度时应设置的Size
