ScreenCapture.CaptureScreenshotIntoRenderTexture

Parameters

Description

Captures a screenshot of the game view into a RenderTexture object.

This variant of screen capture makes it possible to read pixels asynchronously using AsyncGPUReadback, making the process consume less time on the main thread.

For information on when to invoke this method, see the note in ScreenCapture.CaptureScreenshotAsTexture.

public class ScreenCaptureIntoRenderTexture : MonoBehaviour
{
    private RenderTexture renderTexture;

    IEnumerator Start()
    {
        yield return new WaitForEndOfFrame();

        renderTexture = new RenderTexture(Screen.width, Screen.height, 0);
        ScreenCapture.CaptureScreenshotIntoRenderTexture(renderTexture);
        AsyncGPUReadback.Request(renderTexture, 0, TextureFormat.RGBA32, ReadbackCompleted);
    }

    void ReadbackCompleted(AsyncGPUReadbackRequest request)
    {
        // Render texture no longer needed, it has been read back.
        DestroyImmediate(renderTexture);

        using (var imageBytes = request.GetData<byte>())
        {
            // do something with the pixel data.
        }
    }
