This is awesome! Yoyogames supports you! here is a link:
http://www.yoyogames.com/news/53
scroll down, until you reach this:
"*There is a GameMaker Obfuscator that has been updated and now supports 8.1, sprite obfuscation, very powerful obfuscation techniques and dynamic handling of coding styles. For full information, read the topic here: http://gmc.yoyogames...howtopic=373402 This handy software will help many GameMakers to secure their games before publishing."


I think that is pretty cool!

I'm so glad this is out for 8.1. Many thanks to you, Schreib, for your contribution to the Game Maker community and to those who wish to combat code pirates.

Hey thanks for updating this! Even though this is a secondary precaution, it is still incredibly useful to me. Glad to see such a good project not abandoned around here.

Looks amazing.
I have a small question regarding the "Do not modify " list. You say functions and references of "additional packages" should be added to this list. But what is exactly that you consider an additionnal package ?

Also, sadly i get the increase heap size error when i try to obfuscate my game, and executing this command " java -Xmx512m " doesn't seem to help so far. i'll try searching more...

An additional package would be an extension package or anything else that your Game Maker code references. For example, there was a print extension package with GM which would require one to add the print_* functions to the DNM list for them to remain unobfuscated and still work. I do not mean dll's: since strings are not modified, they should work fine.

If you get the heap size error your game must be very large (or I may have made a mistake). Try entering the following into a console:

java -jar "C:\Users\Schreib\Desktop\GMObfuscator.jar" -Xmx1024m

where you replace my example path with your own, of course. (You may want to give it a shot with Xmx512m first). What GM version are you using? If you're still having problems, you can consider sending me your source to the email address on the first page.

Wow, this is wonderful. I've had an idea like this, but, well... idea w/o motivation = nada. I will totally be using this!

Fixed a minor bug which would insert a redundant */ if the code contained a comment starting with // and including */.

Most of the bug fixes that I do are merely use of style or programming that was entirely unexpected to me.

insert nonsense = dnd comment "Cook the beef and onion in a 12-inch skillet over medium-high heat until the beef is well browned." xD

Reuploaded a new version of the obfuscator that warns users when resources have identical names. Because of how resource indices are recalculated/replaced, identically named resources are strongly discouraged. Download from the front page or here:

Another bugfixed version released. Somehow I had programmed some odd room ordering, which made sprite obfuscation a bit odd. Should be fixed now. Also, "empty" sprites and backgrounds no longer stall the loading process (for those who have "Treat uninitialized variables as value 0" on *shakes fist*). Again, I suggest you try the latest version if you have had trouble with the obfuscator before.

Should mention that this bugfix was prompted mostly because someone contacted me. So, if your game gets an error or something weird happens, don't hesitate to PM or email me! My email's in the About info.

It's nice to see you still care about making sure this is up-to-date
I know quite a lot of people would have released it, then stopped caring.

[Schreib]

I thought for the sake of roundedness I might include some schematics I made during the development of this tool. Maybe it will inspire someone.






The obfuscation strategy was in part developed by YellowAfterLife. Kudos again to that.

[Invero]

The links seem to be down. Can someone please upload this and post a link ? I have been searching for hours and all of them are down .

[Schreib]

The first link should work - strangely, it downloads it as a .htm file. Just change the extension to .jar and it should work. I've also updated the mirror in case it doesn't.
