'''
1. Create an image in paint or something with aspect ratio 4:3.
2. Make a billboard with it using: File > Make Billboard... in Alice.
3. Move and resize it so it covers the whole screen.
4. Place the script "main(<billboard name>)" in world.my_first_method. If the name starts with a number, place an underscore before it.
5. Create a new world method, handleMouseClick
6. Create a "When mouse is clicked on" event with the billboard and world.handleMouseClick
7. Create the world variables mouseX and mouseY.
8. In the handleMouseClick method, set these to the mouse position, then call the script "handleMouseClick()".
