How does one make a ragdoll move by itself?

I’ve seen in some game rooms and some youtube videos ( For example: The GMod Idiot Box series ) where there are ragdolls moving their limbs and/or flailing around by themselves. How does one manage to achieve this?

No idea, but my theory is that they use invisible hoverballs. Just a speculation.

Open the spawn Menu and Click “Options”. Select “Hiding”, and go to Draw Physgun Beams and Uncheck the box. This Disables the physgun beam and is used in Machinimas (and other gmod stuff) to make it look like the ragdoll is walking\moving\freaking out on its own.

And you can make it appear as if it’s walking by making a little single-axel car and welding the ragdoll’s feet to the wheels.
