I just started using irrlicht a couple weeks ago and have been working through tutorials learning all the bits and pieces. I'm having a problem that I'm sure is simple and hope someone can clear it up for me, because it's making me insane .
I'm using irrlicht 1.5.1 on Windows XP with Code::Blocks, and OpenGL. Nothing special.
Tutorial 9 (the mesh viewer) illustrates a bunch of GUI features I want to incorporate, but I can't get any of them to work in my application.
At the moment, all I'm trying to do is display some text on top of my rendered scene. In the mesh viewer, if you press F1, the camera position and target are displayed in the upper left corner of the rendered scene. This is exactly what I'm trying to do. I've copied the relevant bits into my application, compile and and run it, but no text appears. I even tried copying the code to build the toolbox, and same thing. It compiles cleanly and displays my test scene fine, but no toolbox.
Please tell me what I'm missing.
Here's the code:
