As title, basically.

I need a list of everything I can add a ScriptPath line to in it's .ini

Well, I don't need it, but would sure be useful.

I don't think there's much of restriction, anything that's a child class of MovableObject should do.

But the script wont run unless the object is moving freely on it's own, and not an attachable to anything.

Oh-ho that is interesting. Seems like it's pretty unrestricted if that's the case.

Though, scripts attached to objects that are attached to objects won't run.

For example, if you attach a script to a gun and an actor is holding the gun, the script on the gun won't run.

You can't have TOO much freedom, right?

...but the script will work so long as no-one is holding the gun, right?

If so then I get it.

Yep.

To get around that, slap an emitter that emits particles with the code.
This tip only applies for held weapons and other attachable.

An exception to the general rule: Magazines. Scripts don't work on magazines, not even when they've been detached from the gun, ie, dropped.

You can slap an emitter on one, causing it to gib when detached into something that can have a script, though.

Perhaps not terribly useful, but there exist a workaround for this. Add the following code to the StartActivity function of your scene:

So that makes detached magazines in the scene become (or be treated like) MOSRotatings?

The ToWhatever functions are called on the creation of all objects with Lua.
