Wolverabid,
There's not much i can add to this. It's common sense. It's only a matter of displaying TFT triggers in JASS and posting them here as tutorials.
If i did it this is how i'd show it..
TRIGGER DESCRIPTION
-Trigger in GUI using
VB-
-Picture of the convert to custom script-
-Posted as JASS-
Instuctions for ROC mappers to create new trigger then click on "Custom script", then paste JASS.
This "hint" is more beneficial for universal triggers like for the trigger mentioned above (for mazes).
Someone with TFT need only make the simple trigger,
If a unit enters tile of type, kill unit
Convert it to JASS then paste it here.
ROC mappers don't have that option in World Editor, but with simple conversion from a willing helper, they can.
Oh, and it doesn't have to be it's own sticky, probably just added with the other useful tips and "read-me-first's".
