这篇博客探讨了如何在Unity中实现相机裁剪区域的自适应功能。通过为场景中的Camera组件添加CameraSize.cs脚本，可以实现裁剪区域根据场景变化自动调整，确保内容始终适配。

在场景中的Camera挂上CameraSize.cs脚本：

using UnityEngine;

//Platform:Android
public class CameraSize : MonoBehaviour
{
    private float defaultcamSize; //初始时设置的Camera的Size
    //默认状态下的宽与高
    private float defaultScreenWidth = 800f;   
    private float defaultScreenHeight = 480f;
    private float w;
    private float h;
    private float newSize;

    void Awake()
    {
        defaultcamSize = this.camera.orthographicSize;
        if (Screen.currentResolution.width != defaultScreenWidth || Screen.currentResolution.height != defaultScreenHeight)
        {
            //print(Screen.width + "," + Screen.height);
            w = defaultScreenWidth / Screen.width;
            h = defaultScreenHeight / Screen.height;
            newSize = w / h;
            this.camera.orthographicSize = defaultcamSize * newSize;
            //print(newSize);
        }
    }
}

在场景中设置了裁剪区域的Panel上挂上panelClipRangeResize.cs脚本：

using UnityEngine;

//Panel面板的裁剪区域的Y轴的自适应
public class panelClipRangeResize : MonoBehaviour
{
    public Camera uicamera;
    //private int defaultScreenWidth = 800;
    //private int defaultScreenHeight = 480;
    //private float w;
    //private float h;

    /// <summary>
    /// w修改宽度:x-z
    /// h修改高度:y-w
    /// </summary>
    void Awake()
    {
        //w = defaultScreenWidth / Screen.width;
        //h = defaultScreenHeight / Screen.height;
        Vector4 clipRange = this.GetComponent<UIPanel>().clipRange;
        this.GetComponent<UIPanel>().clipRange = new Vector4(clipRange.x, clipRange.y+clipRange.w*(1-uicamera.orthographicSize)/2, clipRange.z, clipRange.w * uicamera.orthographicSize);
    }
}
