This is a fork from otclient

What is otclient?

Otclient is an alternative Tibia client for usage with otserv. It aims to be complete and flexible, for that it uses LUA scripting for all game interface functionality and configurations files with a syntax similar to CSS for the client interface design. Otclient works with a modular system, this means that each functionality is a separated module, giving the possibility to users modify and customize anything easily. Users can also create new mods and extend game interface for their own purposes. Otclient is written in C++11 and heavily scripted in lua.

For a server to connect to, you can build your own with the forgottenserver or connect to one listed on otservlist.

Where do I download?

Compiled for Windows can be found here (but can be outdated):

NOTE: You will need to download spr/dat files on your own and place them in data/things/VERSION/ (i.e: data/things/1098/Tibia.spr)


Beyond of it's flexibility with scripts, otclient comes with tons of other features that make possible the creation of new client side stuff in otserv that was not possible before. These include, sound system, graphics effects with shaders, modules/addons system, animated textures, styleable user interface, transparency, multi language, in game lua terminal, an OpenGL 1.1/2.0 ES engine that make possible to port to mobile platforms. Otclient is also flexible enough to create tibia tools like map editors just using scripts, because it wasn't designed to be just a client, instead otclient was designed to be a combination of a framework and tibia APIs.


In short, if you need to compile OTClient, follow these tutorials:

Build and run with Docker

To build and run the client:


The build step should be run just when something on implementation changes.
