The following concerns are +untested: + +- **Raycast accuracy**: a vertical ray from above the road should hit the road + body at the road top surface Y. A ray from below should hit the underside + (the road slab is a closed solid, not a one-sided surface). +- **Collider removal on page rebuild**: when a road page is marked dirty and + rebuilt, the old collider body must be removed **before** the new mesh is + created (otherwise the old body references a freed mesh). +- **Collider removal on page unload**: the body must be removed from the Jolt + world when the terrain page unloads. +- **Multi-page colliders**: a road that spans two terrain pages should have two + independent static collider bodies, one per page, and the seam between them + must not trap small bodies. + +### 1.2 M5.10 Spec-vs-implementation Gap + +The spec (TerrainRequirements.md, M5.10) describes a **perpendicular falloff**: + +> 4. Apply a smooth falloff perpendicular to the road: +> - Full compliance within the road width (all lanes). +> - Linear fade over `laneWidth * 2` outside the outermost lane. +> - Beyond the fade zone, leave the fixup entry empty (use base heightmap + detail noise). + +The current `RoadSystem::complyTerrain()` (RoadSystem.cpp:1564–1629) +**writes fixups only at the vertices of the road surface geometry** — the +top-surface vertices of each wedge and segment. It does **not** iterate beyond +the road surface or apply the `laneWidth * 2` fade zone. + +→ **Resolved**: implement falloff now (see section 1.2a). + +#### 1.2a Required Implementation — Perpendicular Falloff + +In `RoadSystem::complyTerrain()`, after writing the road-underside fixups, +add a second pass that extends laterally from the road centre line: + +``` +For each road surface point P (world pos of a top vertex): + 1. Compute the perpendicular (horizontal) direction away from the road. + 2. The road width at P = totalLanes(P) * laneWidth. + 3. Full compliance zone: fixup already written by existing code. + 4. Fade zone: for lateral offset d in [roadWidth/2, roadWidth/2 + laneWidth*2]: + targetY = interpolate(P.y - roadThickness, baseHeight, fadeFactor) + where fadeFactor = linear from 1.0 to 0.0 over the fade zone + Write targetY into fixup chunk at (P.x + d * perp.x, P.z + d * perp.z) + and (P.x - d * perp.x, P.z - d * perp.z). + 5. Beyond roadWidth/2 + laneWidth*2: no write (fall through to base height). +``` + +To keep the implementation testable, expose a private helper: + +```cpp +static float computeComplianceHeight(float roadSurfaceY, float roadThickness, + float baseHeight, float lateralDistance, + float halfRoadWidth, float fadeWidth); +``` + +This helper is a pure function and can be exercised directly in the test. + +### 1.3 Road Collider Debug Draw (New Item M5.9.6) + +Currently `TerrainSystem::TerrainBodyDrawFilter` only tracks terrain body IDs. +Road colliders are created by `RoadSystem::createPageCollider()` as static +`NON_MOVING` bodies but are not registered with any draw filter. + +**Implementation**: +- `RoadSystem` maintains a `std::set m_roadBodyIds` (populated + in `createPageCollider`, cleared in `destroyPageCollider`). +- A `RoadBodyDrawFilter` (or a combined filter) is wired into + `JoltPhysicsWrapper::setBodyDrawFilter()`. +- The `TerrainEditor` gains a "Show Road Colliders" checkbox + (`getShowRoadColliders()` / `setShowRoadColliders()` on `TerrainSystem` → + forwarded to `RoadSystem`). +- Default: off (same behaviour as terrain colliders). + +## 2. Missing Automated Tests (Implementation Targets) + +These tests must be added to `TerrainTests.cpp`. The test runner already +registers the existing 9 M5 test functions; these 3 new ones (or 4, if +`testRoadColliderRebuild` is separate) will be appended. + +### 2.1 `testRoadColliderInteraction` + +**Purpose**: verify that the generated road `MeshShape` collider produces +correct physical contact (headless-compatible — Jolt CPU queries). + +**Steps**: +1. Create a terrain entity with a two-node road edge (known positions). +2. Pump frames until page activation + road mesh + collider exist. +3. Retrieve `RoadPageGeometry::bodyId`. +4. **Raycast from above**: `JPH::RRayCast` from `(roadCenter.x, roadSurfaceY + 50, roadCenter.z)` straight down. + - Verify hit: body ID matches road body, hit Y ≈ `roadSurfaceY` (± 0.05). +5. **Raycast from below**: cast from `(roadCenter.x, roadSurfaceY - 50, roadCenter.z)` upward. + - Verify hit: body ID matches road body, hit Y ≈ `roadSurfaceY - roadThickness` (underside of slab). +6. **Rebuild**: bump graph version, pump frames, verify old body ID is now invalid (removed) and a new body exists. +7. **Teardown**: deactivate terrain, verify body ID is invalid (removed from physics world). + +### 2.2 `testTerrainCompliance` + +**Purpose**: verify `RoadSystem::complyTerrain()` writes fixups that the terrain +sampling path observes, including the perpendicular falloff. + +**Steps**: +1. Create terrain, add a two-node straight road edge at known positions + (e.g. nodes at (100,0,100) and (500,0,100)). +2. Pump frames until road mesh exists. +3. Call `rs->complyTerrain(ts, roadThickness, laneWidth)`. +4. Sample at a point directly under the road centre: + - Verify `ts->sampleHeightAt(wx, wz) ≈ roadSurfaceY - roadThickness` (± 0.1). +5. Sample at a point far from the road (e.g. (2000, 2000)): + - Verify height matches base heightmap (no fixup). +6. Verify `ts->getFixupChunkCount()` > 0. +7. Test the falloff: + - Compute the total half-width at the sample point: `(lanesAtoB + lanesBtoA) * laneWidth / 2`. + - Sample at `halfWidth + laneWidth` outside (mid-fade): height should be between the full-compliance value and the base height. + - Sample at `halfWidth + laneWidth * 2` outside (fade end): height ≈ base height (± 0.1). + - Sample at `halfWidth + laneWidth * 3` outside (beyond fade): height == base height. +8. `ts->saveFixups()`, deactivate/reactivate, re-sample same points → same values. +9. `ts->clearAllFixups()` → samples revert to base height. + +**Test helper**: `computeComplianceHeight()` unit-test assertions on known inputs (pure math, no scene needed). + +### 2.3 `testRoadSidePrefabs` + +**Purpose**: verify `RoadSystem::spawnSidePrefabs()` creates and destroys +prefab instances correctly. + +**Test prefab fixture**: a minimal `.prefab` JSON file placed in +`src/features/editScene/tests/prefabs/tiny_cube.prefab`. This is a self-contained +test resource; it must not be mixed with user-created prefabs. + +**Steps**: +1. Ensure the test prefab is loadable (the file is registered in a resource + group accessible during tests). +2. Create terrain, add a road edge with one `RoadSidePrefab` pointing at + `tiny_cube.prefab` with `edgeT=0.5, sideOffset=3, leftSide=true`. +3. Pump frames until road mesh + prefabs exist. +4. Verify `RoadPageGeometry::spawnedPrefabs` is non-empty (1 entity). +5. Verify the spawned entity is alive, has a `TransformComponent`, and its + position is approximately the expected world position (edge midpoint + 3 + units left). +6. Bump graph version (add a dummy node+edge) → pump frames. + - Verify old prefab entity is no longer alive. + - Verify `spawnedPrefabs` now contains the new prefab instance. +7. Deactivate terrain → verify spawned prefab entity is not alive. + +## 3. Manual Verification Procedures + +Tests not possible in headless/automated mode.
