PixiJS Particle Emitter - Rotation

Rotation behavior controls a particle’s starting rotation, rotation speed, and rotational acceleration.

Parameters

minStart: number - minimum starting rotation. Think of this as the emitters rotation. Assuming the particle has an emission speed, the particle emits in a direction between minStart and maxStart. 0 to to the right, 90 is down, 180 is left, 270 is up.
maxStart: number - maximum starting rotation.
minSpeed: number - minimum rotation speed. Rotation speed of the particle itself, think of it as a frisbee after it is thrown. It starts facing, and in the direction a person (the emitter) is facing. It then rotates on it’s own axis according to the spin on launch. The spin is defined by minSpeed and maxSpeed.
maxSpeed: number - maximum rotation speed.
accel: number - constant rotation acceleration applied to the particle. Makes it spin quicker over it’s lifetime. Can be set to a negative to reverse initial spin direction.
