FindPlayer Issue

I am having issues with the rust.FindPlayer function. This is the code I am using at the moment:

Code:

function PLUGIN:cmdAllowPlayer(player, cmd, args)
    local target = rust:FindPlayer(args[0])
    print(target.displayName)
end

And the error i am recieving is:

Code:

[Oxide] 6:06 PM [Error] Failed to call hook 'cmdAllowPlayer' on plugin 'CapaPlugin v0.0.1'
File: CapaPlugin.lua Line: 37 attempt to call field 'FindPlayer' (a nil value):

The only other relevant code to this is:

Code:

function PLUGIN:Init()
    command.AddChatCommand('allow', self.Object, "cmdAllowPlayer")
end

I call it by typing "/allow Capadillo" in chat.

I've both copied this code from another plugin and reviewed the Oxide.Game.Rust.dll file where this function is kept and can't find any clues as to why it's giving me the error as so far as I can tell, FindPlayer does exist.

 

Try this

Code:

function FindPlayer(searchedName, player)
  local players = global.BasePlayer.activePlayerList:GetEnumerator()
  local matchingPlayers = {}
   
  while players:MoveNext() do
  if string.match(string.lower(players.Current), string.lower(searchedName)) then
  table.insert(matchingPlayers, players.Current)
  end
  end
   
  if matchingPlayers.Length == 1 then
  return matchingPlayers[0]
   
  elseif matchingPlayers.Length > 1 then
  rust.SendChatMessage(player, "Multiple matching players have been found:")
   
  for _, name in pairs(matchingPlayers) do
  rust.SendChatMessage(player, name)
  end
  return nil
   
  elseif matchingPlayers == 0 then
  rust.SendChatMessage(player, "No matching player has been found")
  return nil
   
  end
end

 

Thanks Ankawi! I had to modify it a little to the following otherwise it wouldn't work for me:

Code:

function PLUGIN:FindPlayer(searchedName, player)
   local players = global.BasePlayer.activePlayerList:GetEnumerator()
   local matchingPlayers = {}
   while players:MoveNext() do
     if string.match(string.lower(players.Current.displayName), string.lower(searchedName)) then
       table.insert(matchingPlayers, players.Current)
     end
   end
   if #matchingPlayers == 1 then
     return matchingPlayers[1]
   elseif #matchingPlayers > 1 then
     rust.SendChatMessage(player, "Multiple matching players have been found:")
     for _, name in pairs(matchingPlayers) do
       rust.SendChatMessage(player, name.displayName)
     end
   elseif #matchingPlayers == 0 then
     rust.SendChatMessage(player, "No matching player has been found.")
   end
   return nil
end

I was really hoping to be able to use a built-in library function, but this is just as good for the moment. I won't mark this as solved just yet though, as this is only a work around. Either way, really great response. Thanks

EDIT: Rewrote it to be a little more like the built in functionality...

Code:

local function FindPlayer(nameOrID, player)
    local activePlayer = global.BasePlayer.activePlayerList:GetEnumerator()
    local partialMatch = {}
    while activePlayer:MoveNext() do
        if activePlayer.Current.UserIDString == nameOrID or string.lower(activePlayer.Current.displayName) == string.lower(nameOrID) then
            return activePlayer.Current
        elseif string.match(string.lower(activePlayer.Current.displayName), string.lower(nameOrID)) then
            table.insert(partialMatch, activePlayer.Current)
        end
    end
    if #partialMatch == 1 then
        return partialMatch[1]
    elseif #partialMatch >= 2 then
        rust.SendChatMessage(player, "Multiple matching players have been found:")
        for key, partial in pairs(partialMatch) do
            rust.SendChatMessage(player, partial.displayName)
        end
    else
        rust.SendChatMessage(player, "No matching player has been found.")
    end
    return false
end

 

Its .FindPlayer() not :FindPlayer()

 

Doesn't make a difference. rust:FindPlayer() is just a shortcut for rust.FindPlayer(rust). If the error was saying something along the lines of "invalid parameter" or "string expected, got userdata" then I would fully agree with you.

At least it is in Lua. In either case, I tried both and received the same error.
