RCWeb Geometry Dash Control App

The RCWeb Geometry Dash Control App (app/geometry-dash-c) is the single-button remote for the Geometry Dash inspired runner. It exists purely to claim the shared runner and send jump inputs into the viewer app.

What it does

  • One input only: The phone UI is reduced to one oversized jump button so the interaction stays faithful to Geometry Dash style timing.
  • Fast room linking: When opened through the QR code, it joins the current RCWeb room and requests control of the main-screen runner.
  • Live run feedback: Score, best score, and alive/crashed state are pushed back from the main viewer so the phone can mirror the run state.
  • Takeover friendly: If another device claims the runner, the current controller is released and can reconnect with a single tap.

How it works

  • First input sends rc.sendFunctionCall("geometry-dash", "geometryDash.joinAndJump", rc.client) to both claim the runner and fire the opening jump.
  • Follow-up taps send geometryDash.jump to the main app, which remains authoritative over all physics and collisions.
  • The controller exposes public callbacks (onAssignedRunner, onScoreUpdate, onStateUpdate, onReleased) so the viewer app can keep the phone UI synchronized.
  • Haptics and short Web Audio tones provide immediate feedback without relying on external media assets.
