Hello Everybody. I need help with the following things in OpenGL If anybody know of any page or tutorial i will appreciate 1. How can I create a selection menu? (1p, 2p, options, cred) 2. How can I connect to different apps? For example from an intro screen the go to menu, when the player selects go to the game etc. 3. How can I add Music not using Direct Audio? 4. When you run any OpenGL App the background screen is black, can I change the color or add texture? Sorry If Im askig alot, but I kindda new and need to finish a project for the end of the month.

Thanks, but I didn''t understand #1, what does collision detection has to do with a menu screen?

You need to read about states.

Basically, what happens is that you have a master application controlling everything else. Each component of your game (title screen, rendering engine, physics, input, etc.) should be a class, and the master application should run all of them.

This master application should have two lists: one for paused states, and one for running states. Then swap stuff around.

For example, if the state is GAME_RUNNING, the paused states would be: title screen and credits. The running states would be: rendering, physics, input and sound.

Then, if the player hits escape, a message is sent to the master application to pause physics and rendering, and to make menu run.

See how that works?

never tought it in that way.. thanks
