Put this into a file called dropweapon.lua and move the file to garrysmod/lua/autorun/client.

It might need few changes if it doesn’t work clientside.

actually its serverside sadly, so garrysmod/lua/autorun/server

Why did you ban him for it…

For the reason I stated. Someone’s asking for help and posting a Lua snippet which might not even work isn’t helping the OP.

Shall i copy all or just a little bit of it??
