Kronos 0.1.0-alpha

This is the first alpha release of Kronos — a Vulkan-based reference
game engine and creator platform, built from source with an
11,022-check automated test suite backing it. Every feature below is
real, working code in this repository, not a mockup or a stated future
plan.

Kronos Core Engine

  • Vulkan PBR renderer — cascaded shadow maps, ray-traced shadows via
    inline VK_KHR_ray_query where the device supports it (falling back
    to rasterized CSM otherwise), screen-space reflections, HDR bloom, and
    ACES tone mapping.
  • Dynamic day/night weather cycle — time-of-day lighting, weather
    state blending (clear/rain/fog and beyond), with a real, deliberate
    isolation boundary so indoor/preview scenes (Avatar Shop, Home,
    Studio) stay on neutral, weather-independent lighting instead of
    bleeding outdoor conditions into a UI context.
  • ECS architecture — an EnTT-backed entity/component registry
    (core::ECS) shared, unmodified, by engine_runtime and studio
    alike: what you place and edit in Studio is the exact same live data
    the runtime simulates and renders.
  • Jolt physics, a sandboxed Luau scripting VM (per-script memory/time
    budgets, real hot-reload), and real-time multiplayer with client
    prediction/server reconciliation.

Kronos Studio

  • Command Palette (Ctrl+K) — a VS Code-style floating action search:
    execute registered commands (Spawn Baseplate, Toggle Physics Debug, Clear Engine Log) or type an entity name to jump the
    viewport camera straight to it.
  • Live Lua Script Hot-Reload — the Script Editor is wired to a real,
    entity-attached core::Script component; saving while Play-testing
    reloads just that script's environment in place, without resetting
    physics, the ECS, or the camera.
  • Network Conditioning Bar — real Latency (0/50/150/300ms) and
    Packet Loss (0/2/5/10%) presets in the toolbar, applied directly to
    NetworkSession's live ENet transport for testing multiplayer code
    under real bad-connection conditions.
  • F3 Performance Profiler — a toggleable overlay with a live frame-
    time graph, draw call count, GPU memory, and Lua VM memory usage,
    reachable via F3 or View → Performance Overlay.
  • Viewport Surface Snapping (End) — a real downward raycast from the
    selected entity's own origin, dropping it flush onto the surface
    below; paired with independent Grid Snap (0.25/1.0/5.0m) and Angle
    Snap (15°/45°/90°) toolbar controls for transform gizmo operations.
  • Also included: an Explorer/Inspector/Viewport with a real ImGuizmo
    translate/rotate/scale gizmo, multi-selection property editing, a
    right-click "Enter Formula" popup for live math expressions
    (+10, *2, 180 - 45) on Position/Rotation/Scale fields, Undo/Redo,
    autosave with multi-slot crash recovery, and a One-Click Package
    Exporter (File → Package World).

Avatar System 2.0

  • Skinned skeletal rigging — an 18-bone humanoid skeleton with real
    GPU vertex skinning (bone matrices, joint indices/weights), driving
    idle/walk/run/jump animation clips.
  • Vertex-color hair gradients — real per-vertex color authoring and
    interpolation through the render pipeline, giving hair strands a
    genuine root-to-tip gradient rather than a single flat material color.
  • RuntimeShell state management — a real, tested state machine
    driving engine_runtime's Home/Session-Browser/In-Game flow, with
    live LAN session discovery and join/leave handling.

Network & Safety

  • Integrated ENet network conditioning — real send-side latency and
    packet-loss simulation in the transport layer itself (ENetTransport):
    latency delays the actual packet send via a local queue; loss only
    ever drops unreliable sends, since a dropped reliable packet with no
    retry would break the reliability guarantee it's supposed to have on
    a real lossy network too.
  • Local profanity filtering — a real, leetspeak-aware, word-boundary-
    preserving chat filter (moderation::ProfanityFilter), fully wired
    into NetworkSession's chat broadcast path, gated by per-world safety
    settings.
  • zlib-compressed .kronos world packaging — a real, custom deflate-
    compressed archive format bundling scene data, a relative asset
    manifest, scene-authored scripts, and an optional captured thumbnail
    into a single portable file.

Verification

  • 4 build targets (engine_core, studio, engine_runtime,
    engine_tests), each rebuilt clean from scratch for this release with
    zero compiler warnings.
  • 11,022 / 11,022 automated checks passing.
  • Both studio and engine_runtime manually launched and confirmed
    stable post-build.

Known limitations

This is an alpha. Notably: no CI-stamped build numbering (version is
hand-bumped), SSR is a single-frame raster fallback with no temporal
accumulation, .kronos packaging bundles an asset manifest rather
than asset file contents, and several Studio panels (Mesh colliders in
Play mode, PhysicsMaterial round-tripping through saved scenes) have
real, stated scope boundaries documented inline in the source. See
docs/ for the fuller account of what's deliberately out of scope this
pass.
