Practical 6

This week we were asked to create an object and code it in such a way that when a certain key is pressed, the object will move in that specific direction

Here's a screenshot of it:

Here is the code used to make this thing move:

In void main
glutKeyboardFunc(Keyboard);

Declared as global are:
int x= 0;
int y=0;

In the KeyboardFunc(Keyboard)

void Keyboard(unsigned char key, int x, int y)
{
switch(key) //check which key is pressed
{
case 'd':
::x++; //add 1 to global x.
break;
case 'a':
::x--; //minus 1 to global x.
break;
case 'w':
::y++;
break;
case 's':
::y--;
break;
}
}

In my display()
glTranslatef(::x,::y,0);
