Invisible Walls to Keep troops on Rooftops

[Blitzen 10]

Happy Holidays!

I'm in the process of building a mission where a helicopter will land ontop of a building and drop off special forces units. I've figured out how to do this, but once the SF units are on the rooftops they always seem to run off the side of the building. The building/island Im using dosent have building postions on the top and therefore I cant tell them to move to a certain spot. I was wondering if there were any invisible/impassable objects that I can put ontop of the roof so that the units wouldnt be able to run off.

Any tips/tricks for fixing this problem?

Thanks

You can set thre waypoint to "SAFE", there is an inviable wall but i'm pretty sure its for Players not AI

You can use this also:

dude disableAI “moveâ€

"Dude" being the units name.

what about setting a small trigger in a rectangle the size of the roof? and then have them stay in this trigger?

I'm not sure how you think that'd work, but I think the best way is to just use the stop and doMove commands. Even if you had some invisible walls set up around the roof, it wouldn't be 100% reliable to stop the A.I. from moving through them.

Place some game logics around the roof, where ever you want the units to move and use the doMove command to make them move there, eg:

unit doMove getPos logic1

Once in position, execute the stop command for them so they don't go wandering off the roof. You can check whether the unit is ready and in the assigned position with the unitReady command.

If you use disableAI "MOVE" like Zulu1 suggested, then the unit will never be able to move again, there's no way to revert that command.

create a trigger to cover the roof, set it to repeat and in the activation field put roofList=thislist. have your special forces units execute this script

;
;"_x exec {nameOfScript.sqs}" forEach [unit1,unit2,units group mySpecialForcesGuy,etc,etc]
;

#start
_pos = getpos _this
~0.01
? _this in roofList : goto "start"
#reposition
dostop _this
_this setpos _pos
~5
_this dofollow (leader group _this)
goto "start"

I only tested it on the ground, but the basic idea should work anywhere...
