How to use JNGP

Well previously, I have been writing my triggers in Jasscraft and then importing the war3map.j file into my map, but Jasscraft is really annoying and everyone says that JNGP is way better.
So I finally got around to downloading JNGP today, but I can't figure out how to use the jass editing functionality on my map.

Nothing shows up under the trigger editor, just like in the normal WE.

What do you mean nothing shows up? A picture would probably be the best thing here.

You have to start world editor through NewGen WE.exe, not World Editor.exe.

Here's the map

That's what you're supposed to see?

You need some triggers...everything looks fine.

Well I was hoping to be able to edit the war3map.j file directly, but I guess that's not possible.

There are no GUI triggers, because everything I had done previously was put in the war3mpa.j file, which JNGP ignores apparently.

The Trigger Editor doesn't show your war3map.j file. It will show the war3map.wtg ( trigger data ) file. In order to show your triggers you need to import your *.wtg file.

So if there is no wtg file, I'm basically out of luck?

Basically, because there's nothing for it to build the trigger editor's trigger blocks out of.

Any particualr reason for editing the war3rmap.j directly when you cna use the trigger blocks to categorize your scirpt and make it look way cleaner?

Well for one thing, not having to deal with those awful udg_s all the time
Also, you can edit the main and config functions that way

That's why we have global blocks =/

in vJass we got custom global blocks, in addition to initializers, which certainly override the need for editing the war3map.j file.

Are there any guides on how to use stuff like that?
