There's security flaw in your script. Anybody with client exploit can control the server w/ admin on it.

I suggest to add one more parametr to CallServerFunc. Special key/code, what admin of server receives on join. Or it can be any other check.

• Colour class still returns just r value, even if you request it g or b or a
• GetHUDItemEnabled is also bugged and doesn't returns right bool

That's all what I remembered.

Add PARTREASON_RECONNECT (feature #3) (idea by sasha19323)

It doesn't work anymore.

Version for LU >0.1.0.15: click

It WAS LU fault, after 0.1.0.15 update there's no any problems with security (anyway nobody can steal your script). And as I've told before, there's no server in LU with your script.

There's no server in LU, which use your script. I don't have your script anymore. And yes, I used LU server and mine server exploit to steal your script and execute server-side code.

This script would be good for Survival/RP gamemodes. You can create it via server(e.g CallClientFunc(plr, null, "PosSound", "track.mp3", Vector(0,0,0), 50); ) or via client(onScriptLoad event or commands). Don't forget to add the sounds in your script.xml file.

Code: ("Client-side script") [Select]

pSounds <- [];

const MAX_RADIUS = 127; //maximal volume
class PosSound
{
  constructor(name, pos, r)
  {
    Pos = pos;
    Name = name;
    Radius = r;
    Sound = ::FindSound(name);
    if (Sound)
    {
      Sound.Open();
      ::pSounds.push(this);
    }
    else
      this.clear();
  }

  function Play()
  {
    if (Sound)
    {
      if (IsPlaying == false)
      {
        Sound.Play();
        IsPlaying = true;
      }
    }
  }
  function Stop()
  {
    if (Sound)
    {
      if (IsPlaying == true)
      {
        Sound.Stop();
        IsPlaying = false;
      }
    }
  }
  function Pause()
  {
    if (Sound)
    {
      if (IsPlaying == true)
      {
        Sound.Pause();
        IsPlaying = false;
      }
    }
  }

  Name = "";
  Pos = Vector(0,0,0);
  Radius = 127;
  Sound = null;
  IsPlaying = false;
}

pPlayer <- FindLocalPlayer();
function onClientRender()
{
  for (local i = 0; i < pSounds.len(); i++)
  {
    local dist = GetDistance(pPlayer.Pos, pSounds[i].Pos).tointeger();
    if (dist <= pSounds[i].Radius)
    {
      pSounds[i].Sound.SetVolume(MAX_RADIUS/pSounds[i].Radius*(pSounds[i].Radius-dist));
      if (!pSounds[i].IsPlaying)
        pSounds[i].Play();
    }
    else
    {
      if (pSounds[i].IsPlaying)
        pSounds[i].Sound.SetVolume(0); //Pause doesn't work properly, so just setting volume to 0
    }
  }

  return 1;

Another bug: objects from content.xml don't works properly. Angle of objs isn't right.

CallServerFunc doesn't work even if i register funcs via RegisterRemoteFunc. Can you exactly explain how to use it?

This snippet based on MP3Report.txt file in "mp3" folder. Snippet parse the file and prevent the crash.

Code: ("Client-side script") [Select]

function FileReadLine(f) //f - file
{
local output = "";
local tmp;
while(true)
{
tmp = f.readn('b');
if (tmp != '\n')
{
output += tmp.tochar();
}
else
{
return output;
}
}
}
function onClientCommand(cmd, text)
{
switch(cmd)
{
case "radio":
{
if (text)
{
if (IsNum(text))
{
local id = text.tointeger();
if (id >= 0 && id < 9)
{
PlayFrontEndTrack(id);
}
else if (id >= 9)
{
local f = file("mp3/MP3Report.txt", "r");
local line;
if (f)
{
while(true)
{
local line = FileReadLine(f);
if (typeof line.find("TOTAL SUPPORTED MP3s: ") != "null")
{
local count = line.slice(line.len()-1);
if (count != "0")
{
PlayFrontEndTrack(9);
break;
}
else
{
Message("[#ff0000]No MP3 files have been found");
break;
}
}
}
}
else Message("[#ff0000]No MP3 files have been found");
}
}
}
}
return 0;
}
}


Exception handlers can be created with

Code: [Select]

seterrorhandler();
With one argument being the function to handle errors.

How works?

· * Event: onServerCrash

Lol, and how do you expect this to work?
It's like requesting a dead person to tell his family he's dead. He can't, he's dead. Same goes with the server. It dies. You'd be happy if it was able to free up some memory before dying.

e.g. Exception Handler

I'm not sure why this would work, care to explain?

I've found, that hashes won't be cleaned after /reconnect. If hash already exists there will be an error.

Just add this code on onScriptLoad client-side event:

Code: ("Client-side script") [Select]

try
{
      HashTable("lalka"); //Here can be any name of table;
}
catch(e)
{
      //if player has been reconnected
      Message("You have been kicked. Please type /q and join again", Colour(255, 0, 0));
      CallServerFunc(null, "KickPlayer", FindLocalPlayer());
}This snippet will help you prevent some /reconnect bugs(objects removing etc).

Here's, anti-debugger code (for anti-trainers and hacks)
