Sometimes referred to as the "Subway Door", this door rotates clockwise or counter-clockwise.
First create your door sector. Shape it like a cross as shown.
Lower the ceiling a couple of units and texture it. Press R
on the ceiling so it will rotate with the sector. Mask four of the
walls and texture them (I used #915). You will probably have to flip
the textures around with F
. Use B
and H
to make those four walls blocked and hittable.
Place the following sprites within the door sector: S[Channel,0], S[Channel,1]
(Speed[0,Speed], M[HearingDistance,Sound]). Angle the S[Channel,0]
down. The S[Channel,1]
will be the pivot point for your door, so I recommend placing it in the center of the door sector. The angle of the S[Channel,1]
determines the direction your door will rotate. Down is for clockwise, and up is for counter-clockwise.
