Are there any open source games where the source code or the ASLX file can be downloaded to examine how they are put together?

All Quest games are open source :-) Download a game and you will get a.quest file. Rename it to .zip and you can open the ZIP file and extract the aslx source file

Cool. Thanks.

Speaking of which, is there a way to lock the open source? Like prevent users from opening it?

I just mention this because a friend of mine is making a game and his entire open source was opened and then his game was basically stolen. It was a different system than Quest. So I was just curious if there was a way to prevent that from happening.

I think the only way to do this is to prevent people from downloading the game and to force them to play it online. But for this you have to change the textadventures.co.uk site and add this feature.

Well. Damn. That stinks. Thank you, Pertex. ^_^

I've no idea how it's actully done, but to take a guess at it:

professional games are likely made with their own engines/kits/code languages that they created/built (like quest), which prevents people from being able to open their files, game/executable/exe and library/DLL files (UN-like quest, as it's '.aslx' files can be opened by any text editor software --- though not run without the quest '.exe' which is similar to professional games and/or also like the '.quest' file, well if it wasn't unzippable anyways, for the online playing of quest), and which they keep that engine/kit/code private (UN-like quest), and so, along with also of course encrypting their game/source code, people can't break into it, as they'd need to know the engine/kit/code used, in order to figure out how to then decrypt the game/source code, in order to pirate/hack the game. Maybe there's some games that you can't even use Assembly Language to 'hex editor' hack the game's data, but there are some games where you can do this, as everyone is probably aware of. Ultimately, maybe the only protection is the use of force (courts/law/law enforcement). The movie industry is the best example, surely having paid off the FBI, to punish anyone plagerizing movies, as you see the warning on every movie made, but you don't see such a warning for any other media/industry... Movie industry must have paid off the FBI to be in bed with the FBI... as they're the only ones to have such strong protection by the FBI.

 as they'd need to know the engine/kit/code used

And the Quest source code is open source so even if there would be a sort of encryption you could find it in the code

Compress the code so that the files are not readable by anything but the computer.

How would you compress open source Quest files and still have it playable for the downloadable version? I'm not sure that it's possible. @_@
