Using Screenshot as Texture
I want to take a screenshot and use it as a material texture for another object.
Script so far:
public IEnumerator TakeSnapshot(int width, int height)
{
yield return new WaitForSeconds(5);
Texture2D texture = new Texture2D (width, height, TextureFormat.RGB24, true);
texture.ReadPixels(new Rect(0, 0, width, height), 0, 0);
snapshot = texture; }
then im using
fotoPlane.renderer.material.mainTexture = snapshot;
but this is just creating a gray texture instead of getting the screen image.
i forgot the texture.Apply(); after texture.ReadPixels. That solved it. I will leave the question here in case someone has the same problem.
StartCoroutine(TakeSnapshot(Screen.width,Screen.height));
public IEnumerator TakeSnapshot(int width, int height) { yield return new WaitForSeconds(0.1F); Texture2D texture = new Texture2D (width, height, TextureFormat.RGB24, true); texture.ReadPixels(new Rect(0, 0, width, height), 0, 0); texture.Apply(); snapshot = texture; }
and then
gameObject.renderer.material.mainTexture = snapshot;
Hey this worked great for me, but I am getting an error ReadPixels was called to read pixels from system frame buffer, while not inside drawing frame. Any way to fix this?
Nice. It looks like using "yield return new WaitForEndOfFrame();" might be a little cleaner.
Very useful information! Thanks a lot!=)
Thank you it’s very useful for me. I was wondering if it’s possible to snapshot a specific region of the screen? I try to make a little drawing game and I want to save only the region of the paper. Any idea how can I do that? Thank you
