This is actually really simple now.

Just go into your root/usermaps/zm_mapname/scripts/zm/zm_mapname.gsc

Then add:

level.perk_purchase_limit = 4;

under:

zm_usermap::main();

Change 4 to the amount of perks you want.

Where did you figure out how to do this? Is there Treyarch documentation somewhere?

I was just looking through the _zm_perks.gsc script and found it there. Most of the stuff is found this way.

There is a lot of documentation made by Treyarch though located in docs_modtools inside your bo3 folder.

Most of the documentation there is tutorials, except the first file that is a htm document that contains a very useful function list along with some other stuff.

Thanks. I don't know the first thing about scripting and I've been trying to learn. I have a bit of C++ knowledge and have watched/read a lot of tutorials but can't even figure out how to get text to display when the player spawns.
