Doriax Engine

Doriax Engine is a free, lightweight, open-source game engine and integrated editor for creating 2D and 3D games. Design scenes visually, script gameplay in Lua or C++, and export projects from one unified environment.

Free for personal and commercial use under the MIT License — no royalties and no sign-up required.

Build in 2D and 3D

• Integrated visual editor: scene hierarchy, component inspector, resource browser, animation timeline, code editor, play mode, and export tools.
• Lua and C++ scripting: iterate quickly with Lua, use compiled C++ for native performance, or combine both in one project.
• Data-oriented ECS: a lightweight Entity Component System designed for efficient, cache-friendly runtime performance.
• 2D workflow: sprites, tilemaps, sprite and tileset slicing, polygons, animation, 2D lights, normal maps, and occluder shadows.
• 3D workflow: GLTF/GLB and OBJ models, PBR materials, skeletal animation, morph targets, mesh instancing, terrain, particles, dynamic lights, and shadows.
• Physics: integrated 2D and 3D physics powered by Box2D and Jolt Physics.
• Rendering and shaders: OpenGL, Vulkan, Metal, and DirectX backends with a shader-aware export pipeline and editable built-in shaders.
• Built-in AI assistant: describe tasks in natural language to create entities, write or edit Lua and C++ scripts, and build projects inside the editor.
• Six export targets: Windows, Linux, macOS, Android, iOS, and HTML5.
