Game Loop

A game loop is the backbone of your game. It loops around, and every frame re-draws the screen.

But first we need to initialise the window:

fun main() {
    w = Window(20, 20)
}

This creates the window, with a width and height of 20. It'll just be blank at the moment though.

Next, every frame, the game loop needs to do 3 things:

clear the screen
re-draw the scene
and then update the screen (or, terminal)
Finally, wait for a bit.

Here is some code to do this:

fun main() {
    w = Window(20, 20)
    while(true) {
        w.clear()
        // Code to draw stuff
        w.printScreen()
        Thread.sleep(100)
    }
}

In this snippet, the while(true) repeats indefinitely, w.clear() clears the screen, and w.printScreen() updates the terminal.

If there was any code to draw something in // Code to draw stuff, then there would be something on the screen.

Now, lets do some interesting stuff.
