Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Cheers,
Kirupa

Thread: [C++] Keyboard Codes

    [C++] Keyboard Codes

    I'm using the OpenGL/Glut library. In the handleKeyPress function, I attempted to display the key that was pressed. To my surprise, the cout is only triggered when the exit key is pressed. So how can I find the number that corresponds to the key? Anyone have a chart?

    Code:
    void handleKeyPress(unsigned char key, int mouseX, int mouseY) {
    	cout << "key: " << key << endl;
    
    	switch (key) {
    		// escape
    		case 27:
    			exit(0);
    			break;
    	}
    }

    Check out the decimal value, that's your key code.

    The cout should get triggered when the code reaches that line... weird, have you tried sticking a breakpoint and stepping through?
    MS Paint FTW!

    Which ones correspond to the left, down, right, and up keys?
