Making certain tools donator-exclusive

[FoxtrotJosh]

I've set up a "donator" group in my 'users.txt' file. I've got a certain tool that I want to make donator-exclusive, but I'm not sure how. I looked around the Garry's Mod wiki and found Player.IsUserGroup but I'm not sure how to check this on a certain player.

The example on the wiki initialises 'player' by using 'players.GetAll()[1]' (the first player), but I'm not sure how to check a specific player. I came across the 'Player.GetByID' function on the wiki but I'm still not sure how to utilise this and the other function to check if a player is in the 'donator' group.

Help would be appreciated,
Thanks

[lua]function UseTool( player, traceline, toolmode )
if( toolmode == "omgdonatortool" or
toolmode == "killeverythingtool" )then
return player:IsUserGroup("donator"); --or "return:player:IsDonator();" if the example below is added.
end
end
hook.Add( "CanTool", "HerpDerpToolCheck", UseTool )[/lua]
Or incorporate this

[lua]
local meta = FindMetaTable( "Player" );
function meta:IsDonator()
return self:IsUserGroup("donator");
end
[/lua]
