Gmod walking animation test

Here is a walking animation I created using Garry's Mod
How I made this:
I put on the invisible playermodel ( so the camera wouldn't see me )
I then selected "Drawing" and then selected "Physgun beams" and "Physgun grab holo" ( so the camera wouldn't see my physgun )
Then I placed the camera ( duh )
Then I got a NPC and turned it into a animated prop
I gave the NPC a walking animation
I then walked behind the NPC to make it look like it was walking by itself
That's how I did this
In total, it took me about 20 - 35 minutes to make
Enjoy
