 Undecided I just realized that the openGL camera can't look directly downward (the XZ axis).
I understand why, it's because how could OpenGl derive an angle/perspective with say the given commands
1

       private Point3D Camera = new Point3D(0.0f, 16.0f, 0.0f);
private Point3D CameraLook = new Point3D(0.0f, 00.0f, 0.0f);

Well it couldn't.

How can I work around this?

I don't really need the perspective to change. I guess this is what I get for making 2-D esque games in 3-D.

Things I've tried so far:
1. Offsetting the camera by miniscule ammounts (ex 0.1f, 0, 0), but that creates a shuddering effect and makes my quads all choppy.
2. glOrtho, either I'm not setting the viewport up right or it's not working for some reason?

You cannot reply to this message, because it is very, very old.

 

Add your game by posting it in the WIP section,
or publish it in Showcase.
