SAGEGame engine, simplified.

A modern TypeScript engine built on BabylonJS with entity composition, event-driven architecture, and Havok physics.

Entity-Behavior Composition

Build game objects from reusable behaviors instead of rigid inheritance hierarchies. Attach, detach, and compose at runtime.

Decouple everything with a wildcard-capable event bus. Components communicate through events, not direct references.

Full rigid body physics powered by Havok. Static and dynamic bodies, forces, impulses, collision detection, all wired in.

Define levels in YAML with scene references, spawn points, entity placement, and post-processing. Load GLB scenes from Blender.

Map keyboard, mouse, and gamepad to named actions with contexts. Analog and digital bindings with edge detection and toggle modes.

Built on BabylonJS 8 for rendering, with thin wrappers that stay out of your way. Full access to the underlying engine when you need it.

First-class Vue composables for building game UI. Reactive bindings to entity state, actions, events, and timers.

Snapshot and restore full game state with a storage-agnostic serialization system. ID remapping, custom hooks, versioned saves.
