If you add another waypoint after the one in the house, say one outside, does the unit proceed to it or does he stay stuck in the house?
If he does proceed to the next waypoint then do this.
1) Change the new WP type to
Scripted 2) Take the code from the
On Activation and put it in a script called
wpscript.sqs3) In the script name field for the scripted WP put
wpscript.sqs (no quotes required)
This is an excellent thread on scripted waypoints by Chris Death, though the attachments seem to be lost.
