Keyboard Codes

I'm fairly new to GLUT programming, and this is a slight problem I had. GLUT calls my keyboard function when a key is pressed. Here is what it looks like:

Code:

---

void keyboard(unsigned char key, int x, int y) {

switch (key) {

    case 'd':
    // do something here
    break;

    default:
    break;
}

}

---

Okay, that works as far as I'm concerned. But obviously I need keyboard codes to read keys such as ESC, and ARROWKEYS. Where do I find the codes for these?

VK_ESCAPE
VK_UP
VK_DOWN
VK_LEFT
VK_RIGHT
etc

The compiler doesn't recognize it. Probably because I'm on a Mac. Or do I need a certain header?

Those key codes are for windows.
You could just output the keycode char to see what it is when those keys are pressed. I don't know much about glut so I can't give you an exact.
Here you go

open up glut.h and look ;)

GLUT_KEY_LEFT
GLUT_KEYF1
etc..

Thanks.... should have thought of it myself.

It didn't work. I opened up the debugger, and the function never gets called when an arrow key or other "special" key gets pressed. It only gets called when a key like 'W' get pressed. This is the line I'm using to get my keyboard input:

Code:

---

// (main function)
glutKeyboardFunc(keyboard);
.
.
.
glutMainLoop();

---

Got to put glutSpecialFunc

Code:

---

void SpecialKeys(int key, int x, int y)
{
    case GLUT_KEY_UP:
    //do something
}
glutSpecialFunc(SpecialKeys);
//so on so forth

Have a look here for some commonly used glut callbacks

OK good. Thanks for your help. I'm just working through the tutorials on NeHe and they don't cover every thing about game programming, so it's good to have a nice forum like this one :)
