[Unity] 스크린샷 찍는 코드

오늘은 간단하게 Unity에서 스크린샷을 찍어 누끼를 따는데 도움이 되는 코드를 공유하고자 한다.

 

private Texture2D ScreenShot(RenderTexture externalTexture)

{

    Texture2D myTexture2D = new Texture2D(externalTexture.width, externalTexture.height);

    if (myTexture2D == null)

      {

        myTexture2D = new Texture2D(externalTexture.width, externalTexture.height);

      }

 

    //Make RenderTexture type variable

    RenderTexture tmp = RenderTexture.GetTemporary(

        externalTexture.width,

        externalTexture.height,

        0,

        RenderTextureFormat.ARGB32,

        RenderTextureReadWrite.sRGB);

 

      Graphics.Blit(externalTexture, tmp);

       RenderTexture previous = RenderTexture.active;

       RenderTexture.active = tmp;

 

       myTexture2D.ReadPixels(new UnityEngine.Rect(0, 0, tmp.width, tmp.height), 0, 0);

       myTexture2D.Apply();              

      

       RenderTexture.active = previous;

       RenderTexture.ReleaseTemporary(tmp);

 

       byte[] screenshot = myTexture2D.EncodeToPNG();

 

       File.WriteAllBytes(Application.dataPath + "/Screenshots/test.png", screenshot);

 

#if UNITY_EDITOR

              AssetDatabase.Refresh();

#endif

 

              return myTexture2D;

}
