The default is usually ok but you might
want to make a fast or slow door.
How far your door opens, 90 degrees by default.
Usually this is correct.
Makes the door open in the other direction.
Same as using -90 instead of 90 for the distance
Makes the door non-solid, so you can't be blocked by it.
Makes the door only open one direction.
Otherwise you can push the door open from either side.
The door will not close by itself,
you will have to use it again to close it.
Probably more realistic.
Makes the door rotate around the X Axis.
Good for a trap door with the hinge on the North/South edge.
Makes the door rotate around the Y Axis.
Good for a trap door with the hinge on the East/West edge.
And I have no more to say.
