I have a rectangular OpenGL window.
I want to display a black screen with small blocks falling down(tetris). Then i need 2D.
I have made the OpenGL window, but my questions are:
1.How do I ready for 2D? (Including how to use the glOrtho function)
2.How do I make a custom coordinatesystem which I can actually understand?

something like thisI don't really understand your custome coordinates question. I think you mean how do I know where the points are. Well, if you look at the GLortho2D function you will notice that the w axis goes from 0 to w(usually 640, 800, 1024), the same for h. Then you just pick points from there. Is that what you mean?Code:void init(GLint w,GLint h){ glViewport (0, 0, (GLsizei) w, (GLsizei) h); glMatrixMode (GL_PROJECTION); glLoadIdentity (); gluOrtho2D (0.0, (GLdouble) w, 0.0, (GLdouble) h); }
exactly d:
I didnt understand a I am sillyI am sillyI am sillyI am silly of the OpenGL coordinate system..
I am silly? Somehow, i get the feeling a moderator has seen my post...or isnt it allowed to write words like
TIHS?

We ruthlessly filter bad grammar. Even if the word weren't censored, it wouldn't make sense for that use anyway.
My best code is written with the delete key.
It causes problems when talking about the << >> operators (in the binary sense).
...but why use roundabouts like glu when i can use pure API?
