name: pixijs-ticker description: "Use for PixiJS v8 Ticker and render loop control: add/addOnce/remove, deltaTime/deltaMS/elapsedMS, UPDATE_PRIORITY, maxFPS/minFPS, speed, shared/private ticker." license: MIT

Use this for per-frame logic, animation timing, ticker priority, and render-loop control.

Fast Path

app.ticker.add((ticker) => {
  sprite.x += 120 * (ticker.deltaMS / 1000);
});

Rules

• v8 ticker callbacks receive the Ticker object, not a numeric delta as the first argument.
• Use deltaTime for 60fps-scaled movement and deltaMS / elapsedMS for real milliseconds.
• Use UPDATE_PRIORITY when update order matters.
• Use maxFPS, minFPS, and speed sparingly and document why.
• Remove callbacks when objects are destroyed; keep function references stable.
• Know whether you are using app.ticker, Ticker.shared, or a private ticker.

Common Fixes

• Animation speed changed after migration: read ticker.deltaTime or deltaMS from the callback argument.
• Callback keeps firing after destroy: call ticker.remove(fn, context).
• Double updates: check shared vs private ticker use.
