What or how do I protect my code , when I release my game?
I have the commersial version.

if you'll use publish, code will be invisible

It has to be compacted to a resource file (WRS). I'm not sure if this is available in Comm, but it is in Pro...

Do a forum search for file packers, there are a couple that successfully hide all assetts whilst most other packers 'hiding' attempts can be found within C Drive with the usual means.

Thanks for the sugestions. I will try what you al suggested.
