|---|---|
| Used on | |
| Code | // This example is based off the GMDMPickup code (Pickups in the GMDeathmatch mode by garry) customRT = GetRenderTarget("rtTest",128,128,true); // Create a RenderTarget with a size of 128x128 in additive render mode and call it "rtTest" ... local OldRT = render.GetRenderTarget() local w, h = ScrW(), ScrH() // These functions return the size of the CURRENT render target, so we'll want to save them render.SetRenderTarget( customRT ) // Change the RenderTarget, so all drawing will be redirected to our new RT render.SetViewPort( 0, 0, 128, 128 ) render.Clear( 0, 0, 0, 255, true ) // Floodfill with black color cam.Start2D() draw.SimpleText( "Test", "ScoreboardHead", 64,60, Color(255,0,0,255), TEXT_ALIGN_CENTER ) cam.End2D() render.SetViewPort( 0, 0, w, h ) render.SetRenderTarget( OldRT ) // Resets the RenderTarget to our screen |
| Output | A painted RenderTarget "rtTest" which can now be used as a texture for quads for instance. |
Additional Notes
- The additive argument is a different method of rendering alpha on textures, however it is deprecated. More info on it here[1]
