Creating a chat command?

[GodGuardian]

I want to create a new chat command,
on a specific Target, how do I do that?

Will there are two hooks that are very useful. PlayerSay and ChatText.

PlayerSay is handled on the server-side, whilst ChatText is client-side.

If you want to open a derma menu, or anything client-sided, use ChatText:

hook.Add( "ChatText", "blabla", function( in, txt ) 

     if txt == "!test" then --> If the text the player typed up is "!test" then continue

         RunConsoleCommand( "kill" ) --> Run the console command "kill"

     end --> End of the if statement

end )

But if you want to make a chat command that is more server-sided, use PlayerSay:

hook.Add( "PlayerSay", "blablabla", function( ply, text )

    if text == "!test" then --> If the text the player typed up is "!test" then continue

        ply:SetWalkSpeed( 999 ) --> Set the player that typed the commands walk speed to 999

    end --> End of if statement.

end )

ChatText is an awful hook to use, and you didn't use the correct arguments for it {You checked for the player name being "!test"...)
[quote][I]Note, that this isn't working with player messages even though there are arguments for it.

For player messages see GM:PlayerSay and GM:OnPlayerChat[/I][/quote]

And just as the wiki says, use [URL="http://wiki.garrysmod.com/page/GM/OnPlayerChat"]OnPlayerChat[/URL] for a client-side hook.

[lua]hook.Add( "OnPlayerChat", "MyChatCommandIdentifier", function( ply, text )
if ply == LocalPlayer() then
if text = "!MyChatCommand" then
--Do shit
end
end
end )[/lua]

Example for serverside chat commands

[lua]local chatcmds={} --Table of chat commands

local function GetPlayersByNick(nick)
local result={}
for _,ply in pairs(player.GetAll()) do
if(string.find(string.lower(ply:Nick()),nick)) then
table.insert(result,ply)
end
end
return result --Table of players with this name
end

hook.Add("PlayerSay","ChatCommand",function(ply,txt)
if txt[1]!="!" or #txt==1 then return end --Not a command
local args=string.Explode(" ",txt:sub(2))
local cmd=args[1]:lower() --Name of the command
if chatcmds[cmd] then --Check if command exists
table.remove(args,1)
return chatcmds[cmd](ply,args) --Call function for this command
end
--Invalid command
end)

function chatcmds.kill(ply,args) --Adds a simple !kill <player name> chat command
if(#args==0) then return end --Forgot to enter a name
local players=GetPlayersByNick(string.lower(table.concat(args," "))) --Table of players with this name
if #players==1 and ply:IsAdmin() and players[1]:Alive() then
players[1]:Kill()
end
end[/lua]

There are dozens of ways to refer to a player.
How do you want to locate the target?

[GodGuardian]

Done, I just found another one on the internet.
A one that actually answers what I need.
