| Features | Rationale | Getting started |
| Unlicense | Documentation | Roadmap ᕕ(ᐛ)ᕗ |

Features

• C++. C.
• Fast. Simple.
• Modern. Readable.
• Full featured. Extendable.
• Object-oriented. Data-oriented.
• Infinite documentation. Browsable sources.
• Hundred of file formats supported. Unique binary format.
• Royaltie fee. Free and unlicensed.
• Other buzzwords. Small. Direct. Embeddable. Fun.

Rationale

• Minimalistic coding style.
• Less is more, DOD, ECS, KISS.
• Heap allocations under control.
• No installation, no makefiles, fast compilation times.
• Generic 3D editor, that can be decoupled from the project.
• Generic asset pipeline, that can be decoupled from the project.
• JSON workflow: still human-readable, still mergeable.
• Inspiration from: ands, bitsquid, ccxvii, jo, krig, ocornut, procedural, rjm, rlk, sgorsten, stb, vurtun.

Roadmap ᕕ(ᐛ)ᕗ

• 00 Project structure, build system and makefiles.
• 01 Window, rendering contexts and game loop.
• 02 File formats, hashing, encryption and compression.
• 03 Timers, easings and interpolation.
• 04 Input bindings, digital+analog buttons, filters, gestures, chords and combos.
• 05 Linear math, geometry, volumes and collisions.
• 06 Cameras and frustum culling.
• 07 Regions, triggers, trees and spatial partioning.
• 08 Data pipeline and asset journaling.
• 09 World streaming and level loading.
• 10 2D/2.5D/3D/VR renderer and post-effects.
• 11 Fonts, atlases and text rendering.
• 12 Debug draw and debug UI.
• 13 Procedural content, brushes, voxels, noise and CSG.
• 14 Static meshes, decals, skyboxes and skydomes.
• 15 Sprites, sheets and spines.
• 16 Particles, billboards, emitters, trails and paths.
• 17 Skeletal animation, blending, blendspaces, IKs.
• 18 LODs, mesh instancing and scenegraphs.
• 19 Server/client architecture.
• 20 Message pipeline and serialization.
• 21 Digital signals, message buffering and event polling.
• 22 Entity/component/systems and world replication.
• 23 Scripting, bindings and game modules.
• 24 Navpoints, navmesh traversal and pathfinding.
• 25 AI, H/FSM, behavior trees and flocking.
• 26 Game flow and game UI.
• 27 Localization, subtitles and unicode.
• 28 2D/3D audio, HRTF, FFT, filtering and sound occlusion.
• 29 Dialogue, quests and inventory.
• 30 Full Motion Video and integrated cinematics.
• 31 Editor, gizmos, properties, timeline and data tracks.
• 32 Debugger, callstack, inspection, console, leaks, cvars and profiling.

Releases

2019.2 (Monkey3_Icarus), 2019.1 (YOB_Marrow)

Getting started

Execute the make.sh.bat script file to build & run the editor.

Additionally:

• make (launch editor)
• make game [platform] (launch game)
• make make [game] [platform] (make game.exe executable)
• make cook [game] [platform] (cook all raw game assets)
• make pack [game] [platform] (pack all cooked game assets into game.pak file)
• make fuse [game] [platform] (fuse game.pak and game.exe both together)

Disk structure

• editor/, generic 3d editor and viewer.
• engine/, portable engine runtime.
• games/, games and demos.
• tools/, build tools & generic asset pipeline.

Download

Build

AVA as engine:

• Compile the amalgamated engine.c source file to get a functional game engine.
• Compile your game as a dynamic library and place it near the AVA executable.
• Tip: Rename both executable and dynamic library as desired. Ie, game.exe with game.dll will work.
• Tip: Place an .ico icon close to the binary if you want to as well.

cl      engine.c                && echo AVA as engine (Windows)
g++     engine.c                && echo AVA as engine (Linux)
clang++ engine.c                && echo AVA as engine (OSX)

AVA as library:

• Compile your game and link amalgamated engine.c source file with it.

cl      game.c engine.c         && echo AVA as library (Windows)
g++     game.c engine.c         && echo AVA as library (Linux)
clang++ game.c engine.c         && echo AVA as library (OSX)

Redistribution

- game.exe + .ico        (engine player)
- game.dll/.lua/.socket     (game logic) \
- game.rom/.pak        (ro data storage) | game :)
- game.ram/.sql        (rw data storage) /
