[Eggmanfan]

I made a poly object excatly like the wiki said and it won't work I tried to make it follow waypoints but it did nothing it says

Polyobject 10 is empty
Bad Polyobject 10 for anchor waypoint
Ev_Do_Poly_ObjWaypoint: Bad Polyobj 10

I have noticed that the Wiki has something wrong with the polyobject tutorial. It says you could pick any linedef to have type 20, but I believe it must be the line with the greatest number.

I actually said the line with the greatest number in the original tutorial, but it got edited.

You made sure to set the floor height of the front control sector on Linedef Type 22 to the PolyObject number, right?
