    Defold

    Defold

    Free game engine for development of desktop, mobile, and web games

    Defold is an open-source, cross-platform game engine originally developed for 2D games but also capable of 3D — intended to give developers a turnkey solution for building games for desktop, mobile, web, and even consoles. It ships as a full editor/IDE, combining scene editing, asset management, scripting, and build/export pipelines, so developers don’t need to assemble disparate tools themselves. Game logic is written in Lua (with optional native extensions in C/C++ when needed), and the engine uses a component-based system and a message-passing paradigm to manage object interactions — a design that promotes loosely-coupled, reactive game code rather than traditional heavy OOP. Defold is optimized for efficiency: exported games tend to have small binary size and low memory use, making it appealing for mobile, HTML5/web, and lightweight games.

    Monocraft

    Monocraft

    A programming font based on the typeface used in Minecraft

    Monocraft is a font for developers who like Minecraft a little too much. Featuring monospaced characters and tasteful ligatures, I've carefully designed each glyph in Monocraft to be usable in a dev environment while preserving that Minecraft charm. Try it out today and discover why nobody has ever done this before! The characters in this font were based on the typeface used in the Minecraft UI, with a select few glyphs updated for better readability and spacing. Each character has been carefully redesigned to work in a monospaced font. Thin characters like “i” and “l” have been reworked with tasteful tails and serifs to look better in a monospaced environment. Add some spice to your programming life with all new ligature characters. Arrows now look like arrows and comparison operators are easier to see at a glance. After following the installation instructions up above, simply select the "Monocraft" font (note the space) in any application that supports custom fonts.

    Trigger Rally

    Trigger Rally

    A fast-paced free software rally racing game

    A 3D rally simulation with a great physics engine for drifting, over 200 maps, different terrain materials like dirt, asphalt, sand, ice etc. and various weather, light and fog conditions give this rally simulation the edge over many other free games. You need to make it through the maps in often tight time limits and can further improve by beating the recorded high scores. All attached single races must be finished in time in order to win an event, unlocking additional events and cars. Most maps are equipped with spoken co-driver notes and co-driver icons. Many configuration details for display and audio adjustments can be edited in the well documented plain text configuration file. Additional contributed maps and events are ready for download as plugins. Trigger Rally works well with common low performance laptops from about 2008. And if something like snow flakes and vegetation sprites demand to much from your system you can just disable it.

    Bullet Physics SDK

    Bullet Physics SDK

    Real-time collision detection and multi-physics simulation for VR

    This is the official C++ source code repository of the Bullet Physics SDK: real-time collision detection and multi-physics simulation for VR, games, visual effects, robotics, machine learning etc. We are developing a new differentiable simulator for robotics learning, called Tiny Differentiable Simulator, or TDS. The simulator allows for hybrid simulation with neural networks. It allows different automatic differentiation backends, for forward and reverse mode gradients. TDS can be trained using Deep Reinforcement Learning, or using Gradient based optimization (for example LFBGS). In addition, the simulator can be entirely run on CUDA for fast rollouts, in combination with Augmented Random Search. This allows for 1 million simulation steps per second. It is highly recommended to use PyBullet Python bindings for improved support for robotics, reinforcement learning and VR. Use pip install pybullet and checkout the PyBullet Quickstart Guide.

    Crown Engine

    Crown Engine

    The flexible game engine

    Crown is a general-purpose and data-driven game engine, written in orthodox C++ with a minimalistic and data-oriented design philosophy in mind. Every aspect of the game is controlled through text configuration files. Before shipping, configuration files are compiled to efficient platform-specific binary blobs. Data in memory is organized to achieve the maximum performance possible on every platform. Every game asset is hot-reloadable, code included. Evaluate modifications and adjustments on-the-fly without having to reboot the game every time. Runs and looks equally well both on Linux and on Windows. Designed to be as fail-safe as possible to never lose your work if crashes should occur. Engine plus tools amounts to less than 50K LOC. Written in simple 'C-style' C++. It is easy for anyone to understand and make modifications. All the code is released under the very permissive MIT license and can be downloaded via GitHub by anyone.

    GrimAC

    Fully async, multithreaded, predictive, open source, 3.01 reach

    GrimAC is an open-source anticheat system designed to detect and prevent cheating on Minecraft multiplayer servers through predictive simulation and advanced movement analysis. The project uses a simulation-based detection engine that recreates player movement and physics in order to identify discrepancies between legitimate gameplay and modified client behavior. By analyzing how players move, interact with the world, and send network packets to the server, Grim can detect a variety of cheats such as reach hacks, speed hacks, and anti-knockback modifications. The software is designed to operate asynchronously and with multithreaded processing, allowing servers to maintain high performance even when monitoring large numbers of players simultaneously. Grim supports a wide range of Minecraft versions and can integrate with server platforms used in competitive or large multiplayer environments.
