Keep floor mesh center at origin (X=0, Z=0) so spawn position and existing props stay roughly central. + +**Additional obstacles (nav stress + camera occlusion):** Add 3–4 extra `StaticBody3D` nodes in the `occluder` group, distributed across the expanded area — positioned so the follow camera must work around varying angles. + +**Vertical variation (terraces / steps):** Add 2–3 raised terrace platforms as `StaticBody3D` nodes in the `walkable` group, elevated ~0.5–2.5 m above the main floor, with ramp/step approach geometry. These are `StaticBody3D` siblings of `Floor` under `NavigationRegion3D` so the runtime bake includes them as nav sources. Each terrace: + - Has its own `CollisionShape3D` (BoxShape3D). + - Is in the `walkable` group so ground-pick raycasts hit it correctly. + - Has a small `StaticBody3D` ramp or step approach (also `walkable`) so `NavigationAgent3D` can route onto it within the NEON-8 step/climb parameters (`agent_max_climb = 0.35` in existing NavMesh settings — ramp grade must respect this, or use multi-step approach). + +**MoveReject props:** Keep `MoveRejectPedestal` and `MoveRejectFarPad` in place — they exercise NEON-7 reject behavior and must remain reachable. Shift `MoveRejectFarPad` outward if needed to stay within the expanded floor bounds and remain "far." + +**NavigationMesh settings:** No changes to agent parameters (height=1.0, radius=0.4, max_climb=0.35, cell_size=0.15) — they remain aligned with the player capsule per NEON-8. The stale baked mesh in the scene will update at runtime. The `geometry_collision_mask = 1` stays, so all collision-layer-1 bodies under the region contribute. + +**NEON-7 edge case check:** With a larger floor the server's `step_size` / `MaxDistance` defaults may now allow clicks that would previously have been out-of-range. Document in the README if this changes observed reject behavior; no server code change unless a new reject case is broken (not just shifted in range). + +--- + +## Files to add + +None. All geometry lives in the existing scene file; no new GDScript logic is required. + +--- + +## Files to modify + +| File | Rationale | +|------|-----------| +| `client/scenes/main.tscn` | Replace 20×20 floor with 45×45; add terrace/step platforms and extra obstacle props; update pre-baked `NavigationMesh` vertices (will be overwritten at runtime, but keeping a reasonable approximation avoids editor warnings). | +| `client/README.md` | Add district runbook note: new footprint, vertical variation, intent as stress playground, updated manual-check geometry references. | +| `docs/decomposition/modules/E1_M2_IsometricCameraController.md` | Optional lightweight pointer that this expanded geography is the default QA map for E1.M2 camera stories. | + +--- + +## Tests + +No new automated GDScript tests are added for this story — there is no new GDScript logic. This story is pure scene geometry. + +**Manual verification replaces automated tests:** + +1. **F5** with server running: confirm player spawns and nav bake completes without errors in Output. +2. Click-to-move across the expanded floor, up/down each terrace, and through obstacles — confirm `NavigationAgent3D` routes and `move_and_slide` behaves per NEON-8 tradeoffs. +3. Ground-pick regression: click behind each new `occluder`-tagged obstacle with player in and out of occlusion fade range (per NEON-30 manual check in README). +4. Confirm `MoveRejectPedestal` and `MoveRejectFarPad` still reject correctly. +5. Follow camera: walk to far corners of the expanded floor — confirm `IsometricFollowCamera` tracks smoothly without snapping or losing the player (snap_distance not tripped by longer walks). +6. Interaction radius: walk near `PrototypeTerminal` to confirm range indicators still work correctly. + +--- + +## Open questions / risks + +- **NavMesh bake time:** A 45×45 floor with several terraces will bake more polygons than the 20×20 baseline. Expected to be negligible for `bake_navigation_mesh(false)` on desktop, but monitor Output for a perceptible pause. +- **NEON-7 reject range change:** The server's `MaxDistance` is currently tuned for the old district. Clicks from the far corners of the new floor will be within server range (they're not "too far" in server terms — the server checks xz step size from _current_ position to _target_, not total map size). Confirm no new silent-reject edge cases; document if found. +- **Agent climb on terraces:** `agent_max_climb = 0.35` limits single-step height. Ramps must grade gently enough for the bake to include them as traversable, or use stacked step geometry (~0.30 m rise per step). Verify in Godot editor nav mesh debug overlay before shipping.

With capsule total half-height = 0.9 m this placed the bottom at -0.3 m underground. The stale is_on_floor()==true + _floor_angle_loose_ticks==0 path skipped every move_and_slide(), so Jolt never resolved the penetration and the capsule froze at an intermediate Y. Fix: clamp global_position.y >= CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS (0.9 m) in snap_to_server; force FLOOR_ANGLE_LOOSE_TICKS_AFTER_STOP corrective idle ticks afterwards. 2. Each _try_walk_step_assist() lift (0.11 m) was immediately undone by floor_snap_length = FLOOR_SNAP_MOVING = 0.32 m snapping the capsule back to the lower floor, which was only 0.11 m below the lifted bottom. Fix: add WALK_STEP_ASSIST_SNAP = 0.09 m constant and _step_assist_active bool. While climbing, floor_snap_length uses the smaller constant in both _after_walk_move_and_slide() and the main physics loop. The flag is cleared when the capsule lands cleanly (is_on_floor && !is_on_wall), or when the nav goal is cleared/snapped to server. Also: is_on_wall() now counts as support in _step_assist_has_support() so the assist fires while the capsule is floating but pressed against a step face; _step_assist_active cleared on arrival, snap, and goal-clear; all temporary DBG print() statements removed. --- client/scripts/player.gd | 46 +++++++++++++++++++---- docs/plans/NEON-29-implementation-plan.md | 2 + 2 files changed, 40 insertions(+), 8 deletions(-) diff --git a/client/scripts/player.gd b/client/scripts/player.gd index 3e66592..9b04efb 100644 --- a/client/scripts/player.gd +++ b/client/scripts/player.gd @@ -33,7 +33,15 @@ const WALK_STEP_ASSIST_DELTA: float = 0.11 ## Skip assist when horizontal velocity already aligns enough with want-dir (corners slide slowly). const WALK_STEP_ASSIST_MAX_FORWARD_DOT: float = 0.52 const WALK_STEP_ASSIST_COOLDOWN_TICKS: int = 8 -## Capsule height 1.0 in scene: origin at center, feet ~ **`y - 0.5`**. +## Floor-snap length while step-climbing.

With `_floor_angle_loose_ticks = 0` and a stale `is_on_floor() = true`, the idle path's `_stable_idle_support()` check passed and held the player without calling `move_and_slide()`, preventing Jolt from resolving the penetration. Fixed: clamp `global_position.y ≥ CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS` (= 0.9 m) in `snap_to_server`; also set `_floor_angle_loose_ticks = FLOOR_ANGLE_LOOSE_TICKS_AFTER_STOP` (96 ticks) to force corrective idle physics before the next walk goal. +- **Step assist undone by floor snap (resolved):** Each `_try_walk_step_assist()` cycle lifts the capsule 0.11 m. The prior `floor_snap_length = FLOOR_SNAP_MOVING = 0.32 m` meant the snap always reached the lower floor (0.11 m below the lifted bottom), pulling the capsule straight back down every tick. The player "nudged and stopped" because each lift was immediately cancelled. Fixed: added `WALK_STEP_ASSIST_SNAP = 0.09 m` constant (below 0.11 m so the snap cannot reach the previous floor, but above 0.03 m so it catches the step surface once cleared) and a `_step_assist_active` boolean flag. During active climbing, `floor_snap_length` is set to `WALK_STEP_ASSIST_SNAP` in both `_after_walk_move_and_slide()` and the main physics loop. The flag is cleared when the player lands cleanly on a floor without wall contact (`is_on_floor() and not is_on_wall()`), or when the nav goal is cleared/snapped. ## Open questions / risks From 1944eeafe8eb74a57645dc4986af631652494f91 Mon Sep 17 00:00:00 2001 From: VinPropane Date: Sat, 11 Apr 2026 22:30:07 -0400 Subject: [PATCH 10/77] NEON-29: fix step assist triggering on floor bumps (directional wall check) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The is_on_wall() short-circuits in _step_assist_has_support() and _step_assist_wallish_blocks() caused the assist to fire whenever the capsule touched any wall contact — including the sides of random floor bumps while crossing flat ground toward a distant elevated goal. After a 0.11 m lift, floor_snap_length = 0.09 m could not reach the original floor (0.11 m away) and _step_assist_active never cleared, so the capsule floated permanently. Fixes: - Remove is_on_wall() blanket short-circuit from both functions. - _step_assist_has_support() now takes want_dir_xz and accepts wall-ish contacts only when they oppose the direction of travel (dot < -0.2), i.e. genuine step faces, not sideways bump contacts. - _step_assist_wallish_blocks() relies solely on the directional collision loop (dot < -0.04); no is_on_wall() bypass. - _try_walk_step_assist() reordered to compute want before calling both functions so the same direction vector is used throughout. - Added "floating free" fallback: if _step_assist_active and no collisions and not on floor, clear the flag so FLOOR_SNAP_MOVING restores on the next tick.

Also use WALK_STEP_ASSIST_SNAP instead of FLOOR_SNAP_MOVING in the descend bypass when _step_assist_active is true, so any remaining overlap cannot undo a step assist lift via the large snap. --- client/scripts/player.gd | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/client/scripts/player.gd b/client/scripts/player.gd index 4283bee..75599fe 100644 --- a/client/scripts/player.gd +++ b/client/scripts/player.gd @@ -570,10 +570,15 @@ func _physics_process(_delta: float) -> void: _snap_capsule_upright() return - var feet_y: float = capsule_feet_y(global_position.y, CAPSULE_HALF_HEIGHT) + # Use actual capsule bottom (total half = CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS = 0.9 m) + # so the descend bypass only fires when the goal surface is genuinely below the player's + # physical feet.

**Arrival check using wrong capsule reference (resolved):** `vertical_arrival_error` was called with `CAPSULE_HALF_HEIGHT = 0.5`, giving code-feet at `body_y − 0.5 = 0.4` at floor level. Step surfaces (Y = 0.3) are only 0.1 m from that reference. When the Jolt physics engine nudges the capsule body down to ~0.8 m (bottom hemisphere contacts the step edge), code-feet becomes 0.3 — matching the step surface Y and making `vert_err = 0 ≤ VERT_ARRIVE_EPS`. If the player is also within `ARRIVE_EPS = 0.35 m` horizontally, the arrival check fires immediately, clearing the nav goal before the capsule has moved. Fixed: pass `CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS` (= 0.9) to `vertical_arrival_error` so actual feet = `body_y − 0.9`. Step goal vert_err is now 0.3 >> 0.055 from floor height; arrival fires correctly only once the step assist has lifted the capsule onto the surface (body_y = 1.2, vert_err ≈ 0). Two regression tests added. - **snap_to_server places capsule underground (resolved):** The server stores the raw surface Y from the client's click (e.g. 0.6 for a terrace platform), not the capsule body-centre Y (which should be 0.6 + 0.9 = 1.5). `snap_to_server` was setting `global_position.y` directly to this surface Y, putting the capsule bottom at −0.3 m. With `_floor_angle_loose_ticks = 0` and a stale `is_on_floor() = true`, the idle path's `_stable_idle_support()` check passed and held the player without calling `move_and_slide()`, preventing Jolt from resolving the penetration. Fixed: clamp `global_position.y ≥ CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS` (= 0.9 m) in `snap_to_server`; also set `_floor_angle_loose_ticks = FLOOR_ANGLE_LOOSE_TICKS_AFTER_STOP` (96 ticks) to force corrective idle physics before the next walk goal. - **Step assist undone by floor snap (resolved):** Each `_try_walk_step_assist()` cycle lifts the capsule 0.11 m. The prior `floor_snap_length = FLOOR_SNAP_MOVING = 0.32 m` meant the snap always reached the lower floor (0.11 m below the lifted bottom), pulling the capsule straight back down every tick. The player "nudged and stopped" because each lift was immediately cancelled. Fixed: added `WALK_STEP_ASSIST_SNAP = 0.09 m` constant (below 0.11 m so the snap cannot reach the previous floor, but above 0.03 m so it catches the step surface once cleared) and a `_step_assist_active` boolean flag. During active climbing, `floor_snap_length` is set to `WALK_STEP_ASSIST_SNAP` in both `_after_walk_move_and_slide()` and the main physics loop. The flag is cleared when the player lands cleanly on a floor without wall contact (`is_on_floor() and not is_on_wall()`), or when the nav goal is cleared/snapped. +- **Terrace B step/platform → floor stuck / oscillation (resolved):** `TerraceStepB` and `TerracePlatformB` had box bottoms **coplanar** with the main floor top (Y = 0), which tends to produce bad **internal-edge** behavior with Jolt + `CharacterBody3D`. Raised both roots by **0.015 m** so collision is slightly above the floor slab. Removed descend-only **lip stall / weak–strong peel / snap-cap** toggles in `player.gd` that could flip `floor_block_on_wall` and vertical forces frame-to-frame; while the nav goal is below the feet (descend), `floor_block_on_wall` stays **false** for the whole descend until arrival clears the goal. ## Open questions / risks From 3efe65d9bd926da3eda2b8a6652dc3da921d8448 Mon Sep 17 00:00:00 2001 From: VinPropane Date: Sun, 12 Apr 2026 00:17:09 -0400 Subject: [PATCH 21/77] NEON-29: Descend on-floor gravity + snap cap; revert terrace Y lift Reverts the 15mm TerraceStepB/TerracePlatformB root offset that regressed floor-to-step movement.

Step surfaces (Y = 0.3) are only 0.1 m from that reference. When the Jolt physics engine nudges the capsule body down to ~0.8 m (bottom hemisphere contacts the step edge), code-feet becomes 0.3 — matching the step surface Y and making `vert_err = 0 ≤ VERT_ARRIVE_EPS`. If the player is also within `ARRIVE_EPS = 0.35 m` horizontally, the arrival check fires immediately, clearing the nav goal before the capsule has moved. Fixed: pass `CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS` (= 0.9) to `vertical_arrival_error` so actual feet = `body_y − 0.9`. Step goal vert_err is now 0.3 >> 0.055 from floor height; arrival fires correctly only once the step assist has lifted the capsule onto the surface (body_y = 1.2, vert_err ≈ 0). Two regression tests added. - **snap_to_server places capsule underground (resolved):** The server stores the raw surface Y from the client's click (e.g. 0.6 for a terrace platform), not the capsule body-centre Y (which should be 0.6 + 0.9 = 1.5). `snap_to_server` was setting `global_position.y` directly to this surface Y, putting the capsule bottom at −0.3 m. With `_floor_angle_loose_ticks = 0` and a stale `is_on_floor() = true`, the idle path's `_stable_idle_support()` check passed and held the player without calling `move_and_slide()`, preventing Jolt from resolving the penetration. Fixed: clamp `global_position.y ≥ CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS` (= 0.9 m) in `snap_to_server`; also set `_floor_angle_loose_ticks = FLOOR_ANGLE_LOOSE_TICKS_AFTER_STOP` (96 ticks) to force corrective idle physics before the next walk goal. - **Step assist undone by floor snap (resolved):** Each `_try_walk_step_assist()` cycle lifts the capsule 0.11 m. The prior `floor_snap_length = FLOOR_SNAP_MOVING = 0.32 m` meant the snap always reached the lower floor (0.11 m below the lifted bottom), pulling the capsule straight back down every tick. The player "nudged and stopped" because each lift was immediately cancelled. Fixed: added `WALK_STEP_ASSIST_SNAP = 0.09 m` constant (below 0.11 m so the snap cannot reach the previous floor, but above 0.03 m so it catches the step surface once cleared) and a `_step_assist_active` boolean flag. During active climbing, `floor_snap_length` is set to `WALK_STEP_ASSIST_SNAP` in both `_after_walk_move_and_slide()` and the main physics loop.

Descend relax now also triggers on **shallow floor normal** (`get_floor_normal().dot(UP) < 0.992`) and slightly wider vertical-ish slide band. **`TerracePlatformA`** root **Y = 0.012 m** breaks **coplanarity** with the main floor without the larger gap that hurt **TerraceStepB** approach. +- **Teal cardinal both ways (follow-up):** **Climb:** **`FLOOR_SNAP_MOVING` (0.32 m)** was still active while **`_step_assist_wallish_blocks`** was true, snapping the capsule back to the lower floor each tick and cancelling lifts — cap snap to **`WALK_STEP_ASSIST_SNAP`** in that state; **bigger per-tick lift** (`WALK_STEP_ASSIST_DELTA` **0.16**) and **cooldown 1** tick. **Descend:** reintroduced **`DESCEND_LIP_SNAP_CAP`** when clearly above the lower goal, plus **`descending_stall`** (`horiz_dist` not trivial, **`vh < 0.55`**) to relax **`floor_block_on_wall`** when Jolt reports neither wall nor shallow floor at a cardinal lip. ## Open questions / risks From bfa932c8349419386529b4334178b3c096f9c921 Mon Sep 17 00:00:00 2001 From: VinPropane Date: Sun, 12 Apr 2026 00:49:37 -0400 Subject: [PATCH 29/77] NEON-29: TerracePlatformA cardinal approach treads (geometry fix) Twelve walkable StaticBody treads (three per side) bridge floor to teal lip; darker teal material.
