Target Plays Via Chat

[MrGregsWorld]

Hi!
I am coding a few things(Kind of an archive) for lua codes, and one I am having trouble with is targeting players by chat.
You see this is every administration mod, where admins can type a command and a portion of a players name and it will find them and perform the action on them.

For Instance:
Let's say on a server there are some guys named 'Larry', 'Pual', and 'Joe'
The admin could type a command like 'kick' with a parameter of 'L','Lar', or 'LARRY' and it would pick out him, and only him. Not disturbing 'Paul' or 'Joe'

I would assume I would need to run a 'for loop' for all the players names and branch off that, but I wouldn't know where to start.
Any help would be appreciated. :D

[lua]
function FindPlayer(str)
local matches = {};

for k,v in pairs(player.GetAll()) do
if (v:GetName():lower():match(str:lower()) || v:SteamID():lower() == str:lower()) then
table.insert(matches, v);
end
end

if (table.Count(matches) == 0) then
return false, "No players found!";
end

if (table.Count(matches) > 1) then
return false, "More than 1 player found!";
end

return matches[1];
end

// usage:
local str = "jo" // this is the argument. eg !kick jo
local target, err = FindPlayer(str);

if (!target) then
Msg(err); // because print is broken :'(
return;
end

// target is good to go here!
target:Kick("kicked :P");

hook it into PlayerSay[/QUOTE]

Thanks, but one problem:
When I hook it into PlayerSay
[SUB]hook.Add( "PlayerSay", "FindPlayer", FindPlayer );[/SUB]

I get this error:
[SUB]Hook 'FindPlayer' Failed: [gamemodes\flagrunner\gamemode\init.lua:107] attempt to call method 'lower' (a nil value)[/SUB]

That's because you're doing it wrong. PlayerSay takes a player (sender), a string (chat message), and a bool (public or not). You can't plug what he gave you directly into it because it's a single component of a larger function you're going to have to write yourself.

If you want to write a command parser (and your name isn't, say, Horsey) you're going to need two things — a PlayerSay hook using [url=http://pgl.yoyo.org/luai/i/string.find]string.find[/url] to try to find a chat command, and a table that matches chat commands with hook functions and runs the appropriate function.

And [i]then[/i] you can write a function for your "/kick" command that uses FindPlayer to try to find a single player and kick him.

no i meant like hook.Add("PlayerSay", "TargetPlayers", function(ply, text, bTeam) FindPlayer(string.Explode(" ", text)[1]) end)

something along the lines of that

Still confused like hell, but thanks! I'll look it over and see if I can figure it out.

[lua]
hook.Add( "PlayerSay", "Chat Command", function( ply, text, toall )

local text2 = string.lower(text) -- Make everything lowercase.

if string.sub(text2, 0, #"!kick") == "!kick" then -- Check if the first 5 letters are "!kick"

text2 = string.Explode( " ", text ) -- Make the normal text (not all lowercase) into a table, seperated by spaces. Set what was the lowercase string as the table.
local victim, err = FindPlayer( text2[2] or "" ) -- Assume the first value in the table is the chat command, second should be the player. Send a blank string if there is only one value in the table.

if IsValid(victim) then -- Make sure it's valid.
victim:Kick( text[3] or "Kicked by "..ply:Nick() ) -- If you have a reason (assuming that's after the name), use it. If not, say who kicked the person.
else
ply:PrintMessage( HUD_PRINTTALK, err ) -- Tell the client what error they received.
end

return "" -- Don't send the command to the chat.

end

end )[/lua]
