How do I program the func_door to emerge from the building?Create the size of block you need, then insert it into the building so the edge is on the same grid as the wall. Then, tie it to a func_door entity. Use the angle control in the top right of the entity properties to make it go out in the right direction (check your top down grid map for the direction you need).
"Make sure you put a negative lip on the door equal to the gap between the wall and the catwalk to make sure it reaches all the way!"Find out how many units there are between the building and the catwalk, then on the func_door's properties, under 'lip', type that number in as a negative number.
haha what does that mean?
and I should stop thinking.Actually a very good idea.
