How does a script contained entirely in a trigger work?

I'm fairly new to JASS, and have run into something that baffles me. How can functions contained in a trigger be called on-the-fly by other triggers? I thought things like that had to be in the Map Script.

For example, Vile's Knockback System's functions are all contained in a trigger labled "Knockback Functions", yet the functions in that trigger can be called by other triggers, as is demonstrated in the test map.

I checked the Map Script section, and the only thing in there are the CScache functions. I then tried moving the functions in the "Knockback Functions" trigger into the map script and disabling the "Knockback Functions" trigger, yet I got compile errors.

I would like too understand how this works.

Because all triggers are compiled in descending order based upon creation order.
If you create trigger A before trigger B, then trigger A appears in the map's script file before trigger B.
This also means trigger B can call any of the functions from trigger A, since they're defined.

You should look at a map's .j file for more details.
That's the map script file I refer to.

Oh. That makes sense. What I don't understand then, is why the map wouldn't compile if I put the functions in the Map Script part. Surely that's got to be compiled first in the map script...

As for accessing a map's .j file, do I just open it with a MPQ editor or something? How do I access it?

Off Topic: I like your new Avatar; it's rather (for lack of a better word) nice-looking.

The Custom Script section is indeed compiled before the rest of the triggers.
It even says so in the section's header.

Make sure your functions are spelled correctly and are properly implemented.
If not, they of course won't work.

And thanks. :P
The tides of change called for a new avatar.

This is a case where preprocessors come in handy. Many of the current ones allow you to define sections (libraries/etc) which will automatically be moved to the top of the script, meaning you don't have to have a 2000 line custom script section any more.
