Thanks, I show just the very basics here for beginners but it is really easy once you get your head around the basic ideas I am trying to convey here.
This site only covers the very minimal to get started. When I have time to spare I will show how you can make objects respond to each other while using the laws of physics etc. Vey glad that it has helped you so far :)
Good shout, thanks! I've removed the button entirely for now.
