- Input action dev_toggle_occluder_obstacle (Ctrl+Shift+K): toggle obstacle off nav source via reparent to World, rebake NavigationRegion3D, sync NavigationAgent3D; physics/process/collision hardening unchanged intent.
- Occluder dictionary keys by instance id; related client fixes and README/project input note.
- Plan and review: PARSED_GEOMETRY_BOTH / runtime geometry removal lesson for future mechanics.
Apply the repo-local gdformat output to the touched GDScript files so the pre-push formatting hook passes. This is a formatting-only follow-up to the lint-hook cleanup.
Refactor the bump escape helper and shared test script loading so the branch passes the repo's pre-push GDScript lint checks. This keeps the runtime behavior intact while unblocking push and PR creation.
Harden idle settling so flat ground, obstacle contacts, and rare bump-edge cases stop drifting instead of looping corrective nudges. Also resolves the saved review follow-up items and syncs the runtime docs to the final feet-height and idle-anchor behavior.
ground_pick.gd now checks _collider_is_occluder before the walkable
break: when the ray hits a body in the "occluder" group it advances
OCCLUDER_PICK_THROUGH past the hit point and continues, unconditionally
and regardless of OcclusionPolicy fade state. Non-occluder click
targeting is unchanged.
Three unit tests added to ground_pick_test.gd covering occluder ancestry
detection. Plan open questions and module doc updated.
Review verdict updated to Approved; all blocking issues and suggestions
resolved and documented. Add auto-generated Godot .uid sidecar files for
occlusion_policy.gd and occlusion_policy_test.gd.
Fixes review blocking issue: when the follow target is null (freed,
renamed, or path unresolved) or the Camera3D child is missing,
_restore_all_occluders() is now called before returning so geometry
cannot be left stuck semi-transparent.
Adds OcclusionPolicy resource and wires it into IsometricFollowCamera.
Each _process frame, iterative rays from the camera eye to the player
focus detect bodies tagged "occluder"; their MeshInstance3D surfaces are
overridden with a transparent StandardMaterial3D (fade_alpha=0.25, instant).
Materials restore when the body clears the ray. Null-material surfaces
(e.g. the prototype Obstacle with no material assigned) receive a plain
transparent StandardMaterial3D so they fade correctly.
- client/scripts/occlusion_policy.gd — new Resource (enabled, fade_alpha,
occluder_group, occluder_collision_mask, max_occluder_cast_depth,
occluder_count_log_threshold, is_valid)
- client/resources/isometric_occlusion_policy.tres — default instance
- client/scripts/isometric_follow_camera.gd — occlusion_policy export,
_update_occlusion pipeline, _apply_occluder_fade/_restore_occluder helpers,
static occlusion_policy_is_valid guard, _exit_tree cleanup
- client/scenes/main.tscn — Obstacle tagged "occluder", policy assigned
- client/test/occlusion_policy_test.gd — new GdUnit4 unit tests
- client/test/isometric_follow_camera_test.gd — policy guard static tests
- docs/decomposition/modules/E1_M2_IsometricCameraController.md — NEON-27
snapshot + readability demo gate note
- docs/plans/NEON-27-implementation-plan.md — null-material decision recorded
Align plan, client/server README, E1.M1 snapshot, and code review note with
the chosen design: descend bypass favors smooth stepped surfaces; multi-click
around obstacles is OK. NS-24 remains for idle jitter.
Zero-velocity move_and_slide each physics tick still reapplies floor snap and
collision, which often reads as vibration. If there is no walk goal (or we
just arrived), velocity is zero, and is_on_floor(), return early.
User-requested rollback to the pre-72eef09 behavior: skip nav waypoints when
auth goal.y is below body (floor pick vs mid-capsule), steering xz straight at
the goal — good for bump departure, bad for gray-box detours. Revert
floor_snap_length to 0.28 to match that snapshot.
Restore a straight Godot nav pattern: steer toward get_next_path_position until
finish or final approach, then toward goal; horizontal-only arrival by xz.
Removes footprint rays, bump-step group, and step-off vy layering that fought
the engine. Slightly raise Player floor_snap_length for small ledges.
Per-frame wall-normal + goal boosts fought a flipping wall normal and capped
re-vectoring, causing back-and-forth jitter. Drop _apply_bump_rim_wall_unstick
and related helpers/constants; keep direct step-down + footprint logic only.
STEP_OFF_DESCEND_SPEED 2.2 → 1.75.
Remove ticket-style names from collider/footprint APIs (_collider_in_bump_step_group,
_departing_bump_step_to_lower_floor, touches_bump_step). Editor group string stays
ns19_bump in one const until main.tscn renames the group.
Convex frustum sides turn goal steering into tangential rim slide with little
net progress. When footprint still hits ns19_bump and dest floor is lower by
at least STEP_OFF_MIN_DROP, add horizontal wall-normal push (if it does not
strongly oppose goal) plus a small goal-direction boost, cap xz speed.
Slightly raise STEP_OFF_DESCEND_SPEED for the step-off branch.
Premature arrival used _floor_y_under_body() vs dest footing; at the rim that
can read floor while xz is already within ARRIVE_EPS, clearing the walk goal.
Match step-down logic: compare destination footing to footprint max_y and
cache footprint scan once per physics frame.
