Writing a role-playing game using rg3d

#1 Character controller

Important notes:

The engine is suitable for any kind of games, not only shooters, the fact that there are two 3d shooters that were made with the engine, and a set of tutorials about 3d shooters just means that @mrDIMAS loves 3d shooters. There will be more tutorials about games in different genre, but again - nothing stops you from making an RPG, RTS, rogue-like, etc.

Screenshots

These screenshots are from Station Iapetus which is a commercial project made with the engine.

These screenshots are from rusty-shooter which is a big demo for the engine.

Examples

There are many examples covering various aspects of the engine. Also don't hesitate to create an issue or ask on Discord if you need help!

Features

Exceptional safety, reliability, and speed.
PC (Windows, Linux, macOS) and Web (WebAssembly) support - Check online example.
Deferred shading.
- Renderer based on OpenGL 3.3 Core (released in 2010) which means that your game will run on almost any relatively modern GPU.
- Directional light.
- Point light + shadows.
- Spot light + shadows.
- Bump mapping.
- Screen-Space Ambient Occlusion (SSAO).
- Soft shadows.
- Volumetric light (spot, point).
- Instancing - render lots of objects without any overhead.
- Fast Approximate Anti-Aliasing (FXAA)
- Parallax mapping.
Custom shaders and rendering techniques.
Render in texture.
Sky box.
2D support.
Multi-camera rendering.
Multiple scenes.
Lightmap generator.
Fully customizable vertex format.
Level-of-detail (LOD) support.
Scene graph with pivot, camera, mesh, light, particle system, sprite nodes.
Built-in save/load - save/load the state of the engine in one call.
High quality binaural sound with HRTF support.
Skinning.
Particle systems with soft particles.
A* pathfinder.
Navmesh.
FBX Loader.
Full TTF/OTF fonts support (thanks to fontdue and ttf-parser crates).
PNG, JPG, TGA, DDS, etc. textures (thanks to image crate).
Compressed textures support (DXT1, DXT3, DTX5)
Advanced node-based UI with lots of widgets.
Animation blending state machine - similar to Mecanim in Unity Engine.
Animation retargetting - allows you to remap animation from one model to another.
Async asset management (textures, models, sound buffers).
Advanced physics (thanks to the rapier physics engine)
- Rigid bodies.
- Rich set of various colliders.
- Joints.
- Ray cast.
- Many other useful features.
Core library.
Fast iterative compilation
- Debug: ~3 seconds
- Release: ~8 seconds
Lots of examples.

Frequently asked questions

Q: Does rg3d use ECS?

A: No. It uses generational pools (arenas) which are optimized for efficient memory management to retain more static type safety.

Q: Examples running too slow on my PC, FPS is too low, help!

A: First, make sure you run examples on the discrete GPU, not on a built-in of your CPU. Built-in GPUs are very slow and not suitable for rg3d. Second, make sure your discrete GPU is powerful enough to run modern games at a decent frame rate.

Supported Operating Systems

Windows - full support
