Baker Coordinator

Core entry point for the package

The BakerCoordinator is the single entry point for runtime navmesh baking. It replaces the legacy NavMeshBaker and manages the NavMeshBakerService internally.

Create a Baker Coordinator in the scene by going to GameObject -> Runtime Navmesh Baker -> Add Navmesh Baker

Overview

  • One entry point that creates and manages the NavMeshBakerService

  • Profile-driven via NavMeshBakeProfile (mode, size, thresholds, agent types, area costs)

  • Bake Modes supported:

    • Continuous AABB — moving bubble around a target

    • Grid Cells — streaming window of fixed cells

    • One Shot — full-scene bake once at startup

  • Center Target (player, camera, or any transform) drives where Continuous AABB and Grid Cells bake

  • Works with any number of DynamicNavMeshSurface components in the scene

  • Exposes runtime controls, bake queue stats, and diagnostics in the inspector

Typical Setup

  1. Menu: GameObject → Runtime Navmesh Baker → Add Coordinator

  2. Create/assign a NavMeshBakeProfile

  3. Set Center Target (player or main camera) — required for Continuous AABB and Grid Cells; optional for One Shot

  4. Ensure bakeable areas use DynamicNavMeshSurface

  5. Enter Play Mode

Inspector Reference

Properties

  • Profile Reference to a NavMeshBakeProfile. Defines bake mode (Continuous AABB, Grid Cells, One Shot), sizes, thresholds, intervals, agent types, and area costs.

  • Center Target Transform to follow when computing bake volumes or selecting grid cells. Not required in One Shot mode.

  • Service Panel Shows the NavMeshBakerService owned by this coordinator. If missing, a warning appears with Add Service Component (advanced; normally not needed). Displays runtime metrics (Play Mode only):

    • Queued / In-Flight / Skipped(no-src) — job queue state

    • Update p95 / Collect p95 / Schedule p95 (ms) — 95th percentile timings for each stage

Actions

  • Start Baking — Starts the coordinator’s baking flow (initial enqueue + runtime updates).

  • Bake All Now — Forces a full pass across all registered surfaces immediately.

  • Enqueue Current Grid Cells — Enqueues the active cell and rings around the center target. Enabled only if profile mode = Grid Cells.

  • Run One Shot Bake — (new) Immediately triggers a single full-scene bake when profile mode = One Shot.

  • Open Bake Monitor — Opens the Bake Monitor editor window for a live, multi-surface view.

  • Select Service — Focuses the owned NavMeshBakerService GameObject in the hierarchy.

Public API (Coordinator)

void SetProfile(NavMeshBakeProfile profile);
void SetCenterTarget(Transform target);
void StartBaking();
void BakeAllNow();
void RunOneShotBake();     // new in 1.4.0
NavMeshBakerService GetService();

Best Practices

  • Keep one BakerCoordinator per scene.

  • Use Profiles to switch between modes:

    • Continuous AABB → compact/roaming maps

    • Grid Cells → large/procedural/streaming maps

    • One Shot → handcrafted maps where you want one full bake at runtime

  • Use the Bake Monitor during development to track throughput, hotspots, and job queue health.

  • For spawner workflows, combine placement policies (Require, Prefer, Ignore) with the bake events exposed by the coordinator to ensure AI is placed only after valid navmesh is available.
