I was kind of hoping someone knew where to get the lantern that was in the map Nazi_zombie_crash, but I doubt it.

Basically, how could I make it so that a light follows the player when holding a certain weapon or attachment? Something along those lines.

Edit: I wasn't sure if this was going to involve scripting or not, so sorry if this is the wrong section.

Basically treminaor's Zippo from 2011. - Zippo and Lights 1/7/2011: http://youtu.be/T5jmEgcWSHI

Best method would be through client scripts.
