Hello - I need some help to do this. I want to draw other images and portions of images to an image, without using using GrabImage - is this possible? If not is there a module available that has commands to do this? Thanks - Rico

You need to use Pixmaps for this.

Isn't that what Render To Texture allows you to do?

since when did Render To Texture exist? Unless your talking about indipaths code which is spotty at best.

Often in games I need to draw images to the background screen, and then to keep these changes. For example drawing shapes to the pit in Tetris or destroying the background in a platform game. Gfk - you are right I have been using Pixmaps - First I draw the background image (which is in Pixmap form) to the screen, then I draw the image on this - and then I use GrabPixmap to save the changes to the background screen. What I was thinking though was that it would be more efficient (faster) to draw directly to an image or pixmap without having to use GrabPixmap (which must slow things down a bit?). Some kind of library/module would be good where you have lots of functions to draw images and shapes(rectangles/circles etc) to Pixmaps/images. Brucey - What's RenderToTexture - is it in one of your modules? Thanks - Rico
