What version of A6 Pro? Not all tutorials are compatible, unless you update the code yourself. And for that you need to learn scripting like Fear said!?

You could start by reading the manual to learn everything about the engine and it's tools. Also read the Acknex User Magazine 1-64 and do the C-Script/Lite-C/WED/MED tutorials and workshops. After that you will have the basics and can begin creating your own game.
