Justine Lever Help

[PutraenusAlivius]

1. Put down a slider_door_lever_fixed in the exact spot as the mount, and make it inactive.
2. Create a script area around the mount (this area is the area where slider_door_lever_handle is used on). Make sure you have ItemInteraction enabled in the area's Area tab.
3. Make an AddUseItemCallback for the lever. When the player uses the lever on the script area around the mount, the mount will de-activate, and slide_door_lever_fixed will activate.

You don't have to create the script area, it's fine just to use the handle on the mount.

(If I'm not misstaken)

You are mistaken. Nearly all the thing you see (Seeing things fall, unlocking doors, unlit/lit lamps) are all using scripting. It's very-very hard. But you'll get a grip after a month or two.
