Summary

Addresses "LMB/RMB do nothing" and "hitting people has no consequences". The hero can now shove, punch and emote on foot, the people hit react, and the city remembers it: moods and memories, police or an ambulance, lines in the chat, and sound. The car the player drives now strikes pedestrians too.

What you can do

• Left click / right trigger: shove whoever stands in front of you.
• Hold right click / left trigger: guard (fists up, body squared to the camera, camera pulled in). Left click then throws a jab and a cross in turn.
• 1-5: wave, nod, shake your head, shout, dance. People nearby answer.
• Nothing swings in a car, in photo mode or the overview, in a conversation, under a modal or with the phone open. The click that captures the mouse throws nothing.

What happens to the people you hit

• A light blow: they reel (hit_chest / hit_head) and slide back.
• A hard blow, the third punch in a row, or a fast car: they go down (knockback), lie a while, get up (get_up), then shout at you, run off or walk back. People nearby who saw it run off or shout too.
• The resident who was hit gets a memory and a mood drop (a shove least, a car most, more when knocked down). People who saw it get a memory and a small drop.
• An assault (a knock-down punch, or 3 punches within 60 s) calls the police. Someone a car knocks down gets an ambulance. The crew drives out from the nearest station and stays a while. Each kind is called at most once per 90 s.
• Chat: the victim and a witness post lines (one scene per 8 s, though a harder blow still posts), and a called crew posts a City Alert card.
• Audio: a thump for each blow (a car's is lower and louder), a whoosh for each swing, and the fall.

Implementation

• scripts/fp/actions/actions_feature.gd (new integration feature actions, flag on by default): swings, combo, guard, emotes. Strike and emote presses are read in _unhandled_input (ARCHITECTURE rule 7). A trigger counts once per pull because every motion event past the dead zone reads as pressed. The guard is a held action.
• Traffic: reactions.gd (reel, fall, get up, run off or walk back, witnesses, emote answers) and incidents.gd (memories, mood, crews). New APIs: walkers_near, hit_walker, answer_emote, pose_walker and call_crew. fleets.gd crews can answer a call and stay at the scene. Walkers get a react state, and people.gd / people_kit.gd play the reaction clips.
• car_body.gd strikes people it closes on faster than 0.5 m/s, as hard as the closing speed over 12 m/s, and each person at most once per 1.5 s. The car loses little speed. Drive _report leaves people to person_hit.
• Player: hero_rig.gd gets an action layer (upper-body one-shots, the dance on the whole body, a guard pose) and strike_time, measured on the clip with the new hero_fk.gd (which now also does the foot-contact forward kinematics). FpPlayer.aim_yaw / kick_view and TpsRig.arm_scale are new.
• GameBus: person_hit(at, cause, info) and hero_action(action, at).
• Chat: chat/street_lines.gd, plus a "street" incident icon in chat_panel_row.gd.
• Audio: punch_hit, punch_whoosh and body_fall, synthesized by tools/audio/synth_fp_sfx.py, and a hit emitter type.
• Assets: 7 UAL clips (punch_jab, punch_cross, hit_head, hit_chest, dance, get_up, shout) via tools/characters/build_clips.py. ual.glb grows from 1.0 to 1.3 MB, and the new .res clips and WAVs total about 280 KB. No file is over 5 MB.
• Inputs: act_strike, act_aim and emote_wave through emote_dance. Only this block of project.godot is in the commit.

Tests

• fp_actions_test (new): the rig action layer and strike times; the shove; the jab-cross combo and its knock-down; misses (nobody ahead, behind, out of reach); emotes and their answers; the guard aim and camera; what blocks actions; presses (events, trigger edge, echo, modal, input off) and held guard; the car striking a pedestrian at 36 km/h but not at 1 km/h; teardown.
• fp_chat_street_test (new): victim and witness lines, pacing, severity override, crew cards.
• fp_audio_test: blow, swing and fall sounds.
• fp_core_test: feature count 16. fp_overview_test: on-foot pad lists include the triggers.

Docs

README controls, pause-menu key legend, docs/fp/ARCHITECTURE.md (new "Integration: body actions" row, plus the A, C, E, HC, I and driving rows and the input list), docs/fp/S0-foundation.md §9 (the two signals), the HC clip table, the I-audio asset table, and regenerated API docs.

Validation

• tools/gate.sh full: PASS (38 steps: parse, 35 unit tests, the orbit and first-person smokes).
• tools/gate.sh render --only fp_photo: PASS. The tour adds actions_guard and actions_guard_hud: the hero with the guard up beside someone reeling from a blow.
• pre-commit run --all-files and python tools/checks/run_all.py: PASS, no new findings.
• Every new or touched script passes gdlint, gdformat and the complexity check with no new findings.
