|
NOTE: You should handle the name "Main" (case insensitive) with
|
|
care. With tribunal, modders got the ability to add 'start
|
|
scripts' to their mods, which is a script that is run at
|
|
startup and which runs throughout the game (I think.)
|
|
|
|
However, before Tribunal, there was only one startup script,
|
|
called "Main". If mods wanted to make their own start scripts,
|
|
they had to overwrite Main. This is obviously problem if
|
|
multiple mods to this at the same time.
|
|
|
|
Although most mods have switched to using Trib-style startup
|
|
scripts, some legacy mods might still overwrite Main, and this
|
|
can cause problems if several mods do it. I think the best
|
|
course of action is to NEVER overwrite main, but instead add
|
|
each with a separate unique name and add them to the start
|
|
script list. But there might be other problems with this
|
|
approach though.
