Ignore the stupid sounds, I just added them as temps. It doesnt work however. It just doesnt revive.

I would like to end up making there be a 10% chance of the revived turning traitor.... but that is way over my head!

Did you read my post? it was in said directory. Its not in my addons at all. I fixed it however by creating a servernamed folder in materials, and directing it all to that. Thanks for the help Mr. Gash!

I fixed the sounds, the file path in the lua needed a path update, thanks for the idea.

As for the icons, I changed the location of the files to VGUI/LA, instead of vgui/ttt. I changed EVERY line associated with capital VGUI/LA to vgui/la: In the resource.Addfile, Swep.icon lines, and even in the vmts.

Heres my resource from my spider gun, each resource.addfile is in each gun's shared.lua,a ll like this:
if SERVER then
  AddCSLuaFile( "shared.lua" )
  resource.AddFile("materials/VGUI/LA/icon_zeph_spider.vmt")
end

  SWEP.Icon = "VGUI/LA/icon_zeph_spider"

Thanks for the response Mr. Gash.
I moved the icons to garrysmod/materials/vgui/LA
Sounds to: garrysmod/sound/LA

I changed the resource locations for all icons and sounds. It DID download the sounds, but when using the spidy gun in game I get:
Failed to load sound "to_far.wav", file probably missing from disk/repository (FOR ALL SPIDY SOUNDS)

The icons are doing the samething, re-"downloading" each rejoin while not truly downloading it

Hi there, new to the forums and (somewhat) new to coding TTT. I've had a server for a while and haven't been able to get the icons to work. Since its a cosmetic problem I put it low on my todos, but recently I have spent HOURS trying to figure it out. I have browsed several forums and post and tried troubleshooting methods described in them but to no avail. I'm finally ready to bring the issue to the pros.

I have a few custom sweps. They all work perfectly except for the icons. I had my gfx artist make some icons. I stressed how important it was to follow the guide step by step from badking.net, and not to miss a single instruction (format, etc).
I got the vtfs from him and uploaded it via ftp to my garrysmod/materials/vgui/ttt folder (NOT the vgui/ttt folder in the gamemodes/terrortown, fyi).

I then created a file with the same name, .vmt, and added the lines provided in the tutorial with the correct pathname, using icon_armor.vmt as a template.

I then added the resource.addfile lines to the resources.lua (format identical to the ones already provided by BK.

Right now it is constantly asking me to download the files everytime I join., and the icons ofc dont work

Here the line from my resource.lua:
resource.AddFile("materials/VGUI/ttt/icon_zeph_minigun.vmt")
icon_zeph_minigun.vmt (and .vtf) are in materials/VGUI/ttt/

I says it is downloading materials/VGUI/ttt/icon_zeph_minigun.vmt, and materials/VGUI/ttt/icon_zeph_minigun.vtf.bz2 (or something like that) everytime I join

UPDATE:

I manually added teh vtf and vmts to my personal directory and they work (this didnt happen before, but i changed some coding)

The filenames/directory are still the same however, and they will not work with my fast DL. The keep redownloading for everyone else.  Websyncing (NFO servers) will add the files to my fast DL site (http://lethalaggression.site.nfoservers.com/server).

I dont know why it wont download for them, any ideas?
