void OnGUI()
{
// This function is being called once per event. This means
// it can be called multiple times in one frame. Only in here
// we can call the GUI class functions and no where else.
// Each function needs a Rect. Rects hold 4 variables.
// 2 for position (x,y) and 2 for size (width, height).
// This defines where and how big the selected GUI
// element will be.
// I am pretty sure with each frame this method is called once
// at the very start of the rendering proccess, so that it
// can draw everything we asked on the screen.
// If there is an event, it comes in and checks a few things.
// Things like, did we press any of the buttons? Did we type
// anything in a text box/text area? Did we move a slider?
// In general, this is a pretty cool way to implement a gui.
// Later on we are probably going to add a GUI skin as well.
// It will allow us to mess around with the way everything
// is shown.
// Selected info Label
GUI.Label(selectedRect, selected);
// Credits info label
GUI.Label(creditsRect, "Credits: " + GeneralMapLogic.credits);
// Map name info label
GUI.Label(nameRect, ImportMap.mapName);
// Tower buttons
