玩游戏想记录一下自己超神的瞬间？那么就来看一下如何使用 Unity 截图吧

using UnityEngine;
public class Screenshot : MonoBehaviour{    //截图相机    Camera capCamera;    //保存图片    Texture2D screenShot;
    void Start()    {        capCamera = GameObject.Find("Main Camera").GetComponent<Camera>();    }
    void OnGUI()    {        if (GUILayout.Button("Show"))        {            CaptureCamera();        }    }
    void CaptureCamera()    {        Rect rect = new Rect(Screen.width * 0f, Screen.height * 0f, Screen.width * 1f, Screen.height * 1f);        // 创建一个RenderTexture对象          RenderTexture rt = new RenderTexture((int)rect.width, (int)rect.height, 0);        // 临时设置相关相机的targetTexture为rt, 并手动渲染相关相机          capCamera.targetTexture = rt;        capCamera.Render();        // 激活这个rt, 并从中中读取像素。          RenderTexture.active = rt;        screenShot = new Texture2D((int)rect.width, (int)rect.height, TextureFormat.RGB24, false);        //从RenderTexture.active中读取像素        screenShot.ReadPixels(rect, 0, 0);        screenShot.Apply();
        // 重置相关参数，以使用camera继续在屏幕上显示          capCamera.targetTexture = null;        //避免重复添加的错误        RenderTexture.active = null; 
        //销毁这个对象        Destroy(rt);
        //保存图片        byte[] bytes = screenShot.EncodeToPNG();        string filename = Application.streamingAssetsPath + "/2.png";        System.IO.File.WriteAllBytes(filename, bytes);    }}
