Spinning fans for vents

[Jnon]

I feel like I've seen spinning fans in vents before on maps I've played in the past, but going through the models/prefabs/etc in DarkRadiant, I can't find anything pre-made for it, and searching the Wiki didn't turn up anything I could find.

I know Entities can be moved in DR (hence doors, windows, elevators, etc) but what would I need to do to make a fan blade model spin on its axis inside a fan frame?

This is done by converting the fan to func_rotating via the classname spawnarg. Once converted, check the inherited properties to see a set of spawnargs that control how it rotates.

...and if the model of your fan should also have a rotation (as for example in the greenhouse in HH
VF), then proceed as follows:

1. convert the unrotated model of the "real" fan into a func_rotating (A) as described by dragofer.
2. depending on the orientation, select the x or y_axis property (if you enter zero for both, the fan will rotate around the Z axis)
3. now give A the desired rotation
4. clone A, place it in a blue-room and convert it into a func-static (B)
5. give A the property "bind" - B"

Thank you both! I remember running into the func_* entity types during the tutorials, I should dig into those more and see what else I can do with them.

Took a little tweaking, but I got my fan rotating.
