[Guide] Creating An Account On the Public Test Server (PTS)

Sephus · March 1Mar 1

Horizon's PTS is used for testing and serving the community with a server that showcases Horizon and its features. The community is welcome to use it for the benefit of testing and finding errors. So lets get down to it - Download the @bio provided Horizon client from here. Change the IP Address in data/clientinfo.xml to 15.235.163.198. Connect using the "_m" or "_f" method. In this method you add a suffix "_m" for male characters or "_f" for female characters to your username in your account

Single Threaded (Hercules/rAthena) Vs Multithreaded Design (Horizon)
Single Threaded (Hercules/rAthena) Vs Multithreaded Design (Horizon)

Sephus · February 17Feb 17

So, what if I was to say that having a road with 5 lanes is better than having a road with 1. There is a lot more room for cars and they can pass through on different lanes. We can categorize roads by high speed or low speed vehicles. We can bring in more cars to move and pass through in other lanes. We can't do this if we have only 1 lane. That is the benefit of a multithreaded service or a multithreaded server.┬á There are several reasons why multithreading is required for a server but a lot o

Horizon Vs rAthena

Sephus · October 12, 2024Oct 12

Introduction One of the most common questions that comes to mind when thinking of using a brand new emulator is - How is Horizon? and where does it stand as a software compared to rAthena, Hercules or any emulator of the eA family? Horizon came with the philosophy of creating a new emulator from scratch by - Understanding the code complexities of the previous generation and untangling the problems encountered in them within the new generation. Not repeating the same mistakes as which were creat

C++26: pack indexing -- Sandor Dargo

C++26 introduces pack indexing as a core language feature, making it significantly easier to extract specific elements from parameter packs using a familiar subscript syntax. This improvement, proposed by Corentin Jabot and Pablo Halpern, eliminates the need for cumbersome workarounds like recursive templates or boolean expression tricks, providing a more intuitive and readable approach.

Active Update to Repository with 6 Linux and 2 Windows Runners

On 12th March, 2025 we have reinstalled our runners. Runners are those which compile the project in its development environment and release key data that is crucial to the project's stability and testing. We are testing the project on 6 Linux VMs which compile the codebase in both GCC and Clang environments, each having Debug and Release configurations. Debug and Release configurations are the two different kind of configurations that the project can be compiled in. Debug means the project will hold debug information in its compiled state, while Release means a more optimized version of the software is compiled. Both these configuration was well as RelWithDebInfo are an important configuration for the project to be compiled in each runner pipeline.
An example of a runner can be seen inside the laboratory each commit will have a check mark of whether it is passed or failed. Passed indicates a good working state of the project, while fail means a cross mark in red. Both these states are declared by each of the runners. That is why the runners are an important part of the project's development. For example, take a look at the image below -

Each job has either passed or failed or is currently being worked on. These are automations which compile the code as and when it is pushed to the repository. Having this in our project simply boosts the quality and performance of the system.

Horizon Is Now Open Source. The Way It Was.

Horizon is now a public software. I went up and down with it a few times thinking that making a paid software out of it was not a priority for me and something that I didn't want to do in the long run because of the kind of work it is. Horizon is a free open source emulator and it should be kept that way for a lot of reasons. I started it as an open source software and so it should be kept as such. The heart of it is an open and free world of code where you can do anything you can dream or imagine. That shouldn't be taken away, the software will grow as it has been parented and taking it away from its free spirited philosophy makes the dream of it become unkept.
So in the spirit of its freedom and the services we provide for free in this community, Horizon is back on its feet walking itself into the strength and integrity it needs to run like Forrest Gump ran for his freedom.

Horizon's codebase is available at our laboratory - http://lab.projecthorizon.xyz/horizon/horizon
Packet parsers, stress testers and Hercules to Horizon packet converters are all available and listed under our group named Horizon.

Change of Host Machine OS from Windows to Proxmox (Linux)

For those reading this, please change your Avatars again sorry for the inconvenience. It was good to see all your images on the forum. <3

Change of Host Machine OS from Windows to Proxmox (Linux)

So after a long time of dealing with a problem in Windows Server 2022, I finally decided to give it up because I can't be bothered to use it if it keeps giving me issues. I've decided to shift to Proxmox. Some of the data has been lost due to Invision Community being a tardy software as well. Images and files uploaded via our forum are gone, we'll need to reupload them.
All things in all we managed to upgrade ourselves from the shitty lapse of a software Windows has made itself to Proxmox which is running on Linux. Now I'm converting all my drives to the ext4 format for Linux compatibility. 3 Machines have been transferred and I'm looking to do the rest tomorrow or the day after. A lot of work to be done to keep this community going! I love it!
No worries about the work to be done, it's all good. If anything, the site should be much faster due to the lightweight host operating system, kvm benefits and linux host machine hypervisors.
Lets hope that this lasts us well a long time unlike Windows which gave up on us 6 months into our production phase.
