Best rendering mode for a top down RPG
Author
Should I use glOrtho for making a top down rpg? Or would it be better to use the normal gl rendering mode.
If you are making a 2D game I would suggest you use the following functions to set 2D mode:
I got these from someone on these boards, though I've forgotten who...
void glEnable2D(){ int vPort[4]; glGetIntegerv(GL_VIEWPORT, vPort); glMatrixMode(GL_PROJECTION); glPushMatrix(); glLoadIdentity(); glOrtho(0, vPort[2], 0, vPort[3], -1, 1); glMatrixMode(GL_MODELVIEW); glPushMatrix(); glLoadIdentity();}void glDisable2D(){ glMatrixMode(GL_PROJECTION); glPopMatrix(); glMatrixMode(GL_MODELVIEW); glPopMatrix();}I got these from someone on these boards, though I've forgotten who...
If you're using sprites and everything will be in 2D use glOrtho. If you're using 3D models and viewing them from above then use the GL_MODELVIEW matrix mode.

I believe this is what you are looking for. Never hurts to pay homage to a nice post!
@Zmurf, if you ask me for an opinion as the user, I think rpg's look good with a nice 3D perspective (but that's just my view of it, you should go with your instincts [smile]).
