[Solved] Far sight only in specific region

[ReforgedBike]

Hello! I want far sight spell only to be casted if it is targeted within a specific region. So you can only reveal a specific part of the map such as in a dungeon, and not be able to reveal other parts of the map. I started on the trigger below but I cannot find any condition like this: "(Ability being cast) targeting a point in REGION NAME Equal to False." Any help would be appreciated.

• Events
  • Unit - A unit Begins casting an ability
• Conditions
  • (Ability being cast) Equal to Far Sight
• Actions
  • Wait 0.01 seconds
  • Unit - Order (Triggering unit) to Stop.

EDIT: I solved it just now! Finally found it. Boolean comparison, then pick Region - Region contains point, Region with offset 0 contains target point of ability being cast equal to False. Only downside with my current trigger is that any queued orders with shift button will all be canceled due to stop order.

I would advise using 'A unit is issued an order targeting a point' event and check that '(issued order)' is of Far Sight spell and that '(target point of issued order)' is in a given region. If not, pause unit, order it to stop and then unpause it. I would also write some error message to the player so that they understand why it the cast was stopped.

That way the unit will not even start casting the ability, nor start turning to the targeted location, etc.
