Yes. It would be quite difficult to use ScriptComponent usefully if functions could not be saved and loaded.

Makes sens. I feared it could be somehow excluded from saved games and reloaded directly from the dat file (without overwriting other variables from the script... I have strange ideas sometimes).

I'm confused about the minimal savestate: if the rock item was minimal savestate, and I used this script: outside of a function, wouldn't it set rock_1 at WorldPositionY 1 every time they load the game?

No.
