Optional ReadonlyattractAttractor / Repulsor.
true pulls particles toward the pointer with the default strength, false disables it, an object sets the
target (pointer, element or point), strength (negative pushes away), reach and falloff.
Optional ReadonlydragAir Resistance.
How quickly particles lose speed. 0 = no resistance, higher = shorter bursts and slower falling.
Optional ReadonlyfloorFloor Collision.
true uses the canvas bottom with default bounce, false lets particles fall off-screen.
Optional ReadonlygravityDownward Acceleration. Negative values make particles float upward.
Optional ReadonlyswirlLooping Drift.
true uses the default swirl, false disables it, an object customizes it.
Optional ReadonlyterminalSpeed Limit.
Caps the total speed of every particle. Infinity disables the cap.
Optional ReadonlywindHorizontal Acceleration. Positive pushes right, negative pushes left.
Built-in Motion Physics Settings. Range values are sampled per particle, so pieces fall at slightly different rates. Horizontal terminal speed is
wind / drag, vertical terminal speed isgravity / drag.
