ignoring zbuffer
ignoring zbuffer
I have already learned (meaning I think it's true) that setting the EMF_ZBUFFER flag as false for an object, it ignores the Z-Buffer. Question is: Is there a simple way for the object to appear on top always?
Hmmm, and you need this for?
I know that with many First Person Shooters, guns for the first person player have a tendency to clip into walls, which is really nasty looking. Consequently, games like Quake end up using a depth hack to 'solve' the problem.
More specifically, I believe it's glDepthRange (in openGL) that is used in Quake games. I think the values used are something like glDepthRange( 0.0, 0.3 )....but my memory is a bit hazy in that regard.
Is this sort of what you are talking about?

WEee-ee-l I can think of some applications more:
In a lot of strategy games, it can happen than a specific character can't be seen because it is behind a tree or a building. Having a little object over or under it that is always on top solves the problem easily. Another application are the 'flying numbers' I mentiones in a thread I posted just before this. It can also be used in selection GUIs, so the selected object appears on top, etc
Useaful feature, it is, but then ALL features can be useful, if used wisely
