Finding by part of name?

[Sphinxa279]

Hey there, experimenting with the whole Lua thing again, is there a way to select a player from the server, if he has a string in his name for example "crazy" as the string?

Edit:

Also, I've just been looking around the wiki, how would I implement this, use a function or what?

[LUA]if attacker:IsPlayer() then
return false
end[/LUA]

Could I just have it as this:

[LUA]
function attacked(ply)

if attacker:IsPlayer() then
return false

end
[/LUA]

For the first question:
[lua]
function FindPlayerByPartOfName( part )

for _, v in pairs(player.GetAll()) do
if( string.find(string.lower(v:Nick()), string.lower(tostring(part)) then
return v;
end;
end;

end;

function KillAllCrazyPeople(ply, cmd, args)

if (!ply:IsAdmin()) then return end;
for _, v in pairs(FindPlayerByPartOfName("crazy") do
v:Kill();
end;

end;
concommand.Add("kill_crazypeople", KillAllCrazyPeople);
[/lua]
For the second question:
[lua]
function GM:EntityTakeDamage( ent, inflictor, attacker, amount )

if ( !ent:IsPlayer() ) then return end;
if ( attacker:IsPlayer()) then return end;
hook.Call("PlayerTakeDamage", self, ent, inflictor, attacker, amount);

end;
[/lua]

Excellent man, these can just go into the server autorun, or within a gamemode itself?

[marc0303]

In the gamemode.
(If you want to put this in autorun you'll need to make hooks)

[Sphinxa279]

[LUA] function GM:PlayerSpawn( ply )
if player:Name() == "^2OctaOctaGon" then
player:ChatPrint("OctaOctagon the Admin just Respawned!")
else
player:ChatPrint("A non-admin has just repspawned...")
end
end

hook.Add("PlayerSpawn", "Plyspawn", GM:PlayerSpawn)[/LUA]

Just wrote this, any ideas why it doesn't work, I don't have it in a gamemode because it has a hook, does it need to be put in client autorun or the server autorun, or even the main autorun folder?

[marc0303]

Don't put (GM:) when your code is hooked or not in a gamemode.
Also, use ply:Nick()... I don't know what is ply:Name(), I never used it. [LUA]function PlayerSpawn( ply )
if ply:Nick() == "^2OctaOctaGon" then -- Not a good idea to use a name (steamId is better)
for k, v in pairs(player.GetAll()) do -- player: doesn't mean all the player...
v:ChatPrint("OctaOctagon the Admin just Respawned!");
end;
else
for k, v in pairs(player.GetAll()) do
ply:ChatPrint("A non-admin has just repspawned...");
end;
end;
end ;
hook.Add("PlayerSpawn", "Plyspawn", PlayerSpawn)[/lua]
And you need to put this in the server folder (autorun/server/).

Excellent, thanks. I assume the (GM:) is obviously used for Gamemodes and nothing else right?

Yes

[Sphinxa279]

So, does that man I can use functions such as the InitialPlayerSpawn as well as all the other gamemode functions as long as I hook them and don't include the (GM:)?

Yea pretty much.

Thankyou again, any hints or tips on using Lua within Garrysmod, or even general coding hints would be apppreciated.
