doors?

how do i make doors? there's no door entity in hammer and neither a door component in sbox editor. i can add a hinge to a door model in the sbox editor but i don't know how to control it.....

Currently no built in way to do so

Do it the hard way: set an origin and assign the object movement along the Z axis.

Then, logically, you need to make the object physical and update its position only when it touches.
And it's also a good idea to limit the object's movement along the X/Y axis so it doesn't rotate 360 ​​degrees.
