After a year of work the new runtime is underway! We are proud to present the new Leenkx Runtime [LNXRT] formerly known as LNXCORE (runtime makes more sense!) built from these great projects:
V8 + Kinc + Krom + uWS
The runtime has three networking flags
WITH_NETWORKING + WITH_UWS + NETWORK_DEBUG
The WITH_NETWORKING flag will include networking features in the build where the WITH_UWS is meant to toggle between network implementations where leaving WITH_UWS off includes the native socket/websocket networking we have built and WITH_UWS will switch over and include the uNetworking/uWebsockets library which is the fastest in the world. The NETWORK_DEBUG flag is for development purposes and is extremely verbose.
I am currently still moving around code cleaning up things like callbacks,threads,old code, moving into a connection pool and thread pooling and generally testing real world applications now so anyone that would like to help debug and test then please download a test build and throw it in your SDK!
I am currently on a windows laptop so the test build is for windows. For linux or mac you must compile your own to test right now!
Thank you everyone!
Blender 3D just released another LTS version!
We are up to date with the SDK and fully support the new LTS. Send us any bug reports as always and feel free to start testing Blender 5.0 Alpha and send any reports there too!
The Leenkx team @onek8 @wuaeyio @breebee won the 2025 gravity themed Blender Game Jam hosted by Iza Zed with the zero-gravity 3rd person shooter, "Sling Kit" which you can play in the browser.
Game Concept:
The choice between cat or dog must be made within a game of rock paper scissors to determine which of the two brave astronauts would defend the spaceship from oncoming asteroids. Player must control the astronaut and use his blaster to defend their ship. Bumping into energy cans will upgrade the blaster while bumping into shields will restore the ships armor!
Project Features:
- Physics based mechanics
- Music and SFX
- Multiplayer mode
- Mobile touch pad
Tutorial and project files coming soon.
We have updated the SDK to support blender version 4.4+ so make sure to report any issues your facing.
You can update the SDK from the Leenkx preferences or you can download the new zip directly!
A user also requested support for as low as blender 2.8 which we will be working on soon so stay tuned if you need the older blender version!
There have been multiple requests for migrating project files over the past couple of months so I decided to make a quick video tutorial.
I have a file converter in progress which should be ready soon for testing and in the meantime you can follow along this video tutorial to understand the 3-5 min process of manually migrating your project files!
The Global Game Jam team "The Renegades" were invited to an upcomming event so we have prepared a detailed overview tutorial of the entire project file for the lead programmer to study everything we did in 48 hours as we are currently on a trip in India and wont be able to attend.
Here is the video below, and you can get the project files directly from the dev git repository
On the morning of the 24th we hear about a Global Game Jam right in our side of town here in Cosenza Calabria by our friends at Blender Italia so of course we had to head down there and see whos making games!
Yesterday the winners were announced and it was a group of programmers who did not use any fancy big tech engine like Unreal OR Unity but instead hand coded their great game concept in Java and used the microphone audio as the controller! You can find the game jam here!!!
It was a team group event so we jumped in the mix and picked up the players that were left out of the other team drafts! Our name was "The Renegades" coined by our lead graphic designer and youngest member "TheVector"! Our lead programmer Gabriele had only used blender once or twice before so it was our chance to show him what were working with in Blender. He picked up the SDK and within 30 minutes he was already prototyping the mechanics for our project telling me what we needed to do in no time!
You can check out our game jam entry here and you can play the game directly in the browser at https://leenkx.com/archive/rise_of_blorbs/game/index.html
We will be making a tutorial soon on the game files and who knows, maybe we will actually make a 2.0 and turn it into a real game!!!!
