JNGP colors all the scripts, even if it is regular JASS. The resource should say whether it is vJASS. If you see keywords like globals
or struct
or library
in the code, then it is vJASS--and it probably means the implementation is as easy as copy & pasting the code and copy & pasting whatever object editor things it uses. If it uses variables that say udg_
before the name, then it is using regular JASS & you may need to create the variables yourself or copy the GUI variable trigger if they provided one.
