Area Transition

Zephirius

How would I make an area transition undiscoverable by a PC, unless he's got a local variable stored on him allowing him to click the area transition?
The intent behind the proposed script is this: Lock the area transition until the PC has performed x task.

I do stuff like this with an invisible object/placeable and a trigger. Enter the trigger fires the script, script checks for the variable/skill check/whatever, if its there create the invisible object which can be used to transition.

I haven't tried it with a trigger area transition.

Note that if this is multiplayer, I don't believe there is a way to hide it for individual players. It will either be hidden from all or visible to all.
If it is a single player module then you could do as @Quilistan suggested and create an invisible object or use an already existing invisible object and make it useable at some point with the SetUseableFlag function.

For single player, there is an easier way. Just apply a cutscene invisibility effect to the door until the player is eligible to use it.

A door can be placed anywhere - paint a door in a regular doorway, then adjust its location in the left-hand (area contents) palette. The "no visible door" appearance is often most appropriate, for things like gaps in trees or secret doors in walls.

Thanks fellows. Sorry for the belated reply. I'll give these a try.
