Thanks - that may do what I need. I have to admit that I do still get a little confused about using some 2d functions in 3d games.
I thought that it might be possible to read the colour of an entity rather than just pixel at x,y on the screen. So what if you want to know the current rgb of an entity that may be totally or partially masked by another entity?
