sindoring 435e1c95d2 gmp(M02): extract local player movement
Work-Package: M02-GMP-MOVEMENT-001
Agent: sindo-main-codex
Tests: local movement and player input regressions; asset-free scene; renderer dry-run; coordinate, streaming, documentation and coordination gates
Fidelity: preserves current sandbox speed, acceleration, sprint and camera-relative flight behavior; build-12340 parity remains unverified

M02-GMP-MOVEMENT-001 — Local movement state/controller

Ownership

  • Target: M02
  • Program: GMP
  • Owner/Agent ID: sindo-main-codex
  • Branch: work/sindo-main-codex/m02-local-movement
  • Lease expires UTC: 2026-07-16
  • Integrator: M02 milestone integrator

Outcome

Move local velocity, sandbox flight state, acceleration and directional speed calculation from ThirdPersonWowController into a scene-free, independently-testable local movement controller without changing current sandbox motion.

Non-goals

  • Extract terrain queries, camera rig, character presentation or animation.
  • Add jump/fall/swim, server prediction or reconciliation.
  • Change current movement speeds, acceleration, camera-relative flight or ground snap.
  • Gate debug movement by build profile; that remains a separate M02 package.
  • Mark M02 complete or edit its checklist/Evidence.

Paths

  • Exclusive: src/gameplay/movement/, src/tools/verify_local_player_movement.gd, docs/modules/local-player-movement.md, this claim
  • Shared/hotspots: src/scenes/player/third_person_wow_controller.gd, src/tools/verify_player_input.gd, docs/modules/player-input.md, docs/modules/README.md
  • Generated/ignored: local .godot, native DLL, generated ADT resources and renderer corpus

Contracts and data

  • Public API: stateful LocalPlayerMovementController
  • Inputs: immutable MoveIntent, local Godot movement basis and physics delta seconds
  • Outputs: local Godot displacement and read-only velocity/flight state
  • Schema/cache/coordinate contracts: unchanged
  • Consumer: current sandbox player scene; later gameplay composition root

Dependencies

  • Requires: merged input seam on master 14dead1
  • Blocks: terrain query and camera/presentation extraction from the player hotspot
  • External state: none; unit tests use synthetic intents and bases

Verification

  • Commands: dedicated pure movement verifier, player-input regression, asset-free scene smoke, coordinate/StreamingFocus gates, renderer dry-run and repository gates
  • Fixtures: identity/rotated/pitched bases, acceleration steps, sprint and flight transitions
  • Fidelity evidence: exact current 7.0/4.5/4.5 speeds, 28.0 acceleration, 6x sandbox sprint and camera-relative free flight are regression-locked only
  • Performance budget: one small state update per physics tick; no allocation, I/O or scene lookup

Documentation deliverables

  • Inline public API docs for movement state/configuration and update methods
  • Local movement module specification with data-flow, state and sequence diagrams
  • Updated player-input consumer diagram/status and module registry

Simplicity and naming

  • Important name: LocalPlayerMovementController
  • Simplest approach: one stateful RefCounted owning velocity and flight toggle
  • Rejected complexity: generic locomotion framework, ECS component hierarchy and event bus
  • Unavoidable complexity: movement basis remains an explicit local-space input so the pure controller does not discover player/camera Nodes
  • Measured optimization evidence: not applicable

Status

  • State: active
  • Done: claim and isolated worktree from updated master
  • Next: implement controller, migrate scene consumer, test and document
  • Blocked by:
