pixijs-ticker

app.ticker runs registered callbacks every frame and drives app.render() at UPDATE_PRIORITY.LOW . Each callback receives the Ticker instance; read deltaTime as a frame-rate-independent multiplier (≈1.0 at 60fps) or deltaMS for real-time calculations. Quick Start app . ticker . add ( ( ticker ) => { sprite . rotation += 0.01 * ticker . deltaTime ; sprite . x += ( 200 / 1000 ) * ticker . deltaMS ; } ) ; app . ticker . add ( ( ticker ) => { updatePhysics ( ticker . deltaMS ) ; } , undefined , UPDATE_PRIORITY . HIGH , ) ; app . ticker . maxFPS = 30 ; app . ticker . speed = 0.5 ; sprite . onRender = ( ) => { sprite . scale . x = Math . sin ( performance . now ( ) / 500 ) ; } ;
