[Modules] Rekzais OTClient Modules

[M4rcin]

The client now communicates with a separate web socket server and needs no communication to your otserver at all.

When its completely stupid logic - lets make a microservice out of it (in a different language ofc) and lets not validate anything anymore!
Zoomers are hella smart

How is that solution better?

 

[Rekzai]

I mean good for you guys if you do a serverside solution. Otclient already has this feature implemented for the bot so why not make use of it.

This is the easiest solution without taxing the server and without making any source edits.

Everything is open source and free to use. If you have a better solution, post it or open a pull request for it.

I want to make the modules as easy as possible to implement for server owners, that's why I chose a way that requires no source edits.

I am just giving you a hint that your solution is a bad workaround. People can spoof their position and you have no way of validating this.
Oen also gave you a hint but you completely ignored it, polluting your codebase with new technologies that will bottleneck the server even faster than the code you originally wrote.

I'll just do two variants I suppose.
I have one with oens approach already started, just wanted to find a solution for people who can't even compile a server.

Yeah, I did that once, ended up with stupid hacks that at the end were not worth it. So my experienced opinion is... don't. Just work with sources and save yourself all the headaches.

for people who can't even compile a server

These people are the one that will spam you the most about stuff and drive you crazy overtime. Just ignore these low IQ people that can't read.

Appreciate your input and the code snippets you gave me.
Again, just started working with otclient two weeks ago, so I am still learning and trying to figure everything out.
Will probably just release two variants of the module, one that is meant to be used (the one you guys are recommending) and the web socket one just for people who are interested in it and want to take a look at it.
I will make sure to put a proper note that the web socket version is just a showcase.

 

[oen432]

If you are using bot server as the web socket server then it is still C++ that needs to be compiled. So... kinda ironic?

Wanted to just provide a compiled version for the people, but yea, already working on the source edit version.

 

[oen432]

a compiled version

Both Windows and Linux?

 

[Rekzai]

Both Windows and Linux?

Only compiled it for Linux, but that was the plan yes.
If you do a party overhaul, I might just drop that module and work on something else.
Unless you do not release it to the public.

 

[oen432]

Unless you do not release it to the public.

Yup, my work is not free.

 

[Sooh]

i will wait

 

[SixNine]

Its totally fine even to implement source changes, mostly everyone is capable of compiling client or server so i dont see much of issue until code is highly optimized

 

[Ajkillju]

Hello. Is it possible to add the bot again in otcv8? In the server client otc bot has been removed.

Post in thread 'hide Minimap Party Icons'

Apr 27, 2025

Updated icons.lua

in your options.lua in client_options moduel

add

partyIcons = true,

in your

local defaultOptions = {

and then replace your whole

function init()

with

function init()
  for k,v in pairs(defaultOptions) do
    g_settings.setDefault(k, v)
    options[k] = v
  end

  for _, v in ipairs(g_extras.getAll()) do
    extraOptions[v] = g_extras.get(v)
    g_settings.setDefault("extras_" .. v, extraOptions[v])
  end

  optionsWindow = g_ui.displayUI('options')
  optionsWindow:hide()

  optionsTabBar = optionsWindow:getChildById('optionsTabBar')...

Maybe stop sending position change from the client for one. You have server for this. Send party info when party is created, player joins or leaves. Update position of a member that took a step (again, server side).
You won't do that without server source edits btw.

function Player:onStep(fromPosition, toPosition)
    -- This event fires whenever a player moves from one tile to another
    -- Example: Add a fire effect behind the player as they walk
    if fromPosition.x ~= 0 then -- Check if fromPosition is valid (not initial position)
        fromPosition:sendMagicEffect(CONST_ME_FIREAREA)
        fromPosition:sendMagicEffect(55)
    end
 
    -- You can use this for various global walking effects
    -- For example:
    -- 1. Create footstep effects behind players
    -- 2. Trigger zone-based events when players enter certain areas
    -- 3. Track player movement for analytics or game mechanics
    -- 4. Create trailing particle effects for special players
    -- 5. Apply environmental damage (like lava floors)
 
    return true
end

I'm working on party system overhaul

how is that going?
