SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Three.js games built for desktop often break on mobile: touch controls are missing, HUDs overflow small viewports, orientation changes reset gameplay, and performance collapses on low-end devices. This Skill provides a structured playbook for making a Three.js game work properly on mobile web.

Core Features & Use Cases

  • Touch Control Design: Implement movement controls, reachable primary actions, target selection, cancel/reset paths, and non-drag inventory alternatives with feedback for held, unavailable, and queued actions.
  • Responsive HUD Layout: Design portrait and landscape layouts that keep status, target data, inventory, tooltips, and dialogs legible without covering the playfield, and survive orientation changes without resetting state.
  • Performance and QA Discipline: Apply device-appropriate quality defaults, adaptive decorative effects, and test multi-touch, long sessions, audio unlock, background return, reduced motion, and low-end quality in real mobile-size viewports.
  • Use Case: You have a desktop-first Three.js game and need to ship it to mobile browsers. Use this Skill to add touch controls, fix safe-area overlaps, and run a mobile QA pass before release.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add touch controls to a Three.js game?

Add a clear movement control plus reachable primary action buttons, with target selection and cancel or reset paths. Keep controls out of unsafe screen areas, avoid overlapping action zones, and show feedback for held, unavailable, and queued actions.

How do I make a Three.js HUD responsive on mobile?

Design separate portrait and landscape layouts that keep vital status, target data, inventory, tooltips, and dialogs legible without covering the playfield. Handle orientation changes without resetting gameplay state.

Does Three.js performance degrade on low-end mobile devices?

Yes, desktop-tuned scenes often exceed mobile GPU and battery budgets. Use device-appropriate quality defaults and adaptive decorative effects, then verify on low-end quality settings and real mobile-size viewports.

Why does audio not play in my mobile browser game?

Mobile browsers block audio until a user gesture unlocks the audio context. Test the audio unlock flow explicitly, along with pause and background-return behavior, during mobile QA.

What should I test before releasing a mobile web game?

Test touch target sizes, multi-touch input, long play sessions, audio unlock, pause and background return, reduced motion preferences, low-end quality modes, and actual mobile-size viewports in the repository-approved browser.
