ladder script help

[Your Computer]

my mistake . What i wanted was, if the ladder was high in the air, i wanted the ladder area unactive (so the player couldn't climb it yet. but when the player turned the crank which causes the ladder to come down, i want the ladder area to be active. I already know how to simply deactivate an area, i just want to know how to deactivate it when the crank is at a specific state.

That's what SetEntityConnectionStateChangeCallback is for.
