Consolidated from the qa-input-collision-fix-0.1.0 work, applied onto main so
only the changes main genuinely lacks are carried (main already merged the
walkable-demo/collision work independently).
- fix(input): populate the UE 5.8 FInputMappingContextMappingData
DefaultKeyMappings field in ue_create_input_assets.py (the runtime reads
GetMappings()->DefaultKeyMappings.Mappings; the script previously wrote only
the deprecated 'mappings' array, so the cooked game had 0 runtime mappings
and every key silently did nothing — in packaged AND PIE). Regenerated
IMC_Default.uasset. WASD/mouse/Space/R/Escape verified working.
- fix(build): drop editor-only APIs that break the game target build —
UStaticMesh::PostEditChange() (GigLineAssetTools) and AActor::GetActorLabel()
(character ground probe). GigLine and GigLineEditor now both compile clean.
- tools: OS-level uinput input harness (input_emulation.py + input_test.py) and
run_pie.sh for PIE isolation; document the PIE-vs-packaged input test in
Docs/build.md. Removed the temporary SIM/EI/screenshot diagnostics from the
character.
The reported fall-through was a misdiagnosis: the player never fell. The
imported Terrain_DEM had only a bounding-box simple collision proxy, so a
downward trace anywhere in the block hit the terrain at Z 819 (the mesh
bbox max) and the street sat under an invisible 8 m lid. Standing on that
box looked plausible, which is why it read as working.
- add UGigLineAssetTools (C++): force CTF_UseComplexAsSimple on a static
mesh. UE 5.8 dropped bUseComplexAsSimpleCollision and Python cannot set
the flag; the builder also saves the asset, since the flag lives there
and a map-only save silently reverts it.
- spawn (-13336, -1150, 600): inside the carved corridor (the cut is a
10.7 m half-width around the road centreline), lands on the road at 456.
- fix ResetToStart returning to the mid-air PlayerStart captured in
BeginPlay: StartLocation is now captured on the first grounded frame.
- HighResShot 1280x720 instead of "1280 720", which is a multiplier.
- add -qaselftest: scripted walk/reset/pause on a core ticker plus a
swept ground transect. Results: walk 746 cm/2 s with Z steady, reset
0 cm from spawn, pause/unpause 1/0, transect 84 samples 0 holes.
- rebase onto main, keeping the frontage materials and placement fixes.
Tools/ue_build_demo_map.py builds /Game/Hollywood/DemoMap: sun, sky, the hero
facade on the building line, six site meshes imported with collision, and a
player start on the north sidewalk. Tools/ue_import_site.py imports the site
FBXs; terrain, road and sidewalks use complex-as-simple so a simple hull cannot
ramp over the kerbs. Art/blender/site/export_site_fbx.py exports one FBX per
object so each can carry its own collision.
Reset (R) and pause (Escape) join the character and the input context: reset
restores the spawn transform and clears momentum, pause is a real game pause that
releases the cursor. DefaultInput.ini captures the mouse on launch.
Three placement defects found by measuring the imported actors rather than
trusting the plan: the spawn was on the wrong sidewalk because the FBX flip
inverts north, a mirror I added to the exporter double-corrected an already
correct sidewalk, and the street meshes only carry part of the north walk - the
rest is terrain.
AGigLineCharacter: 1.75 m capsule, 1.60 m eye camera, 4 m/s walk, mouse look
scaled in degrees per second (no double DeltaTime), jump. Loaded ahead of a
Blueprint so the demo is playable with no assets wired by hand.
Tools/ue_create_input_assets.py builds /Game/Input headlessly: five 1D actions
and an 11-mapping context. One action per direction instead of per-key modifiers,
because modifier objects do not survive the save path here: a mapping's modifier
array serialises None, and dimensioning a 2D move with per-key axis masks would
need exactly those modifiers. The cost is four action assets rather than two.
Also adds a fourth review camera at eye height and documents it; its approval is
pending.
