Three.js Gameplay Systems

Purpose

Create or evolve a playable browser game loop with clear ownership, responsive controls, deterministic update order, and verified player-facing behavior.

Use When

Starting a new game, repairing a weak prototype, adding mechanics/entities, designing architecture, tuning camera/controls, implementing rules/objectives, or improving game feel.

Workflow

Load references/gameplay-workflows.md as the first action when the task includes first playable setup, architecture, mechanics, entities, input, camera, collision/physics, scoring, objectives, feedback, or feel tuning.

Load references/physics-engine-selection.md before adding or changing physics, collision-heavy gameplay, vehicle movement, rolling balls, mini-golf, pool/snooker, pinball, rigid-body puzzles, character controllers, sensors, high-speed projectiles, moving platforms, or physics QA. Track both references in a reference ledger with yes/no, path, and failure reason. Do not mark the gameplay phase complete while a required reference is skipped.

Load references/checklists/new-game-definition-of-done.md before claiming a new game or first playable slice is complete.

Load references/checklists/endless-runner-premium-quality.md for endless runner work.
