Barnacle Grapple SWEP

A revival(?) of the barnacle grapple (used in HLVR:AI) from Half-Life: Opposing Force, after the original addon disappeared into the abyss without a trace.

This is not a reupload of that addon, this is a replication of it using whatever I can find. This may not be 100% the same.

I originally intended this to be an extension to the Ultra Lite Grappling Hook SWEP, but decided to make it standalone instead.

Please don't think this is a big thing because that isn't my intention for this addon. I simply just wanted to upload a barnacle grapple that worked the same way as the original addon did.

This swep can be found under: Weapons --> Barnacle Grapple

Addon I used for the base code: https://steamproxy.net/sharedfiles/filedetails/?id=2883696475
Addon I got the models/materials/sounds from: https://steamproxy.net/sharedfiles/filedetails/?id=1190561466

Credit goes to Drealengo for the original addon, though they also disappeared along with the addon as well.
