no, you have to find the blizzard.j file in War3Patch.mpq and put it in the jngp\jasshelper folder. then, for custom text/jass, you'll need to put it in jngp\tesh\includes folder as well. i just put it in the tesh\includes and now the functions are listed, finally. i figured this out thanks to Tyrulan from thehelper.net
fyi: custom text looks like this:
incidently, i believe i may have found a bug...anyway i think the bug might be related to the cjass bug i discovered awhile ago regarding the /* */ comments.
well, it's somewhat irrelevant at the moment.
custom script is just what jass is. the thing is you can use one liner custom script actions in gui if you like...so...basically when you use custom script in gui, you're really using jass while using gui.
so, custom script is custom text except that it's only a single line of custom text in an otherwise gui trigger.
custom text is jass triggers. a jass trigger can be written from scratch, or converted from an entire gui trigger to jass and then edited further, if desired.
using custom script is like writing just a tiny part of a jass trigger into a gui trigger.
edit: well now that can't be right or i did something stupid because now i'm getting 100 errors.
edit2: i guess at some point i forgot to quit editor and start it back up...silly me
