Screenshot of Unity3d

1.application.capturescreenshot ("Screenshot.png", 0);

2.

2. Exture2d CaptureScreenshot2 (rect rect)
4. {
6. Create an empty texture first, size can be set according to the implementation needs
8. Texture2d screenshot = new texture2d ((int) rect.width, (int) Rect.height, Textureformat.rgb24,false);
12. Reads screen pixel information and stores it as texture data.
14. Screenshot.readpixels (rect, 0, 0);
16. Screenshot.apply ();
20. These texture data are then converted into a PNG image file
22. byte [] bytes = Screenshot.encodetopng ();
24. string filename = application.datapath + "/screenshot.png";
26. System.IO.File.WriteAllBytes (filename, bytes);
28. Debug.Log (string. Format ("Screenshot of a picture: {0}", filename);
32. Finally, I return to this Texture2d object, so that we directly, the diagram in the game, of course, this according to their own needs.
34. return screenshot;
36. }
38. Truncate fullscreen (for example, note: There is a UI):
    CaptureScreenshot2 (New Rect (screen.width*0f, screen.height*0f, screen.width*1f, screen.height*1f));

    
    Section 4 (e.g.):
    CaptureScreenshot2 (New Rect (screen.width*0.25f, screen.height*0.25f, screen.width*0.5f, screen.height*0.5f));

3.

2. Texture2d Capturecamera (camera camera, rect rect)
4. {
6. Create a Rendertexture object
8. Rendertexture RT = New rendertexture ((int) rect.width, (int) rect.height, 0);
10. Temporarily set the targettexture of the relevant camera to RT and manually render the relevant camera
12. Camera.targettexture = RT;
14. Camera. Render ();
16. PS:---If this adds a second camera, you can implement an image that is visible only to a few of the specified cameras.
18. Ps:camera2.targetTexture = RT;
20. Ps:camera2. Render ();
22. PS:-------------------------------------------------------------------
26. Activates the RT and reads the pixels from it.
28. rendertexture.active = RT;
30. Texture2d screenshot = new texture2d ((int) rect.width, (int) Rect.height, Textureformat.rgb24,false);
32. Screenshot.readpixels (rect, 0, 0);//Note: At this time, it is reading pixels from the rendertexture.active
34. Screenshot.apply ();
38. Reset the relevant parameters to use the camera to continue to display on the screen
40. Camera.targettexture = null;
42. Ps:camera2.targetTexture = null;
44. Rendertexture.active = null; jc:added to avoid errors
46. Gameobject.destroy (RT);
48. Finally, these texture data into a PNG image file
50. byte [] bytes = Screenshot.encodetopng ();
52. string filename = application.datapath + "/screenshot.png";
54. System.IO.File.WriteAllBytes (filename, bytes);
56. Debug.Log (string. Format ("Screenshot of a picture: {0}", filename);
60. return screenshot;
62. }
