Class RotationBehavior

A Rotation behavior that handles starting rotation, rotation speed, and rotational acceleration.

Example configuration:

{
    "type": "rotation",
    "config": {
         "minStart": 0,
         "maxStart": 180,
         "minSpeed": 30,
         "maxSpeed": 45,
         "accel": 20
    }
}

constructor

  • new RotationBehavior(config: { accel: number; maxSpeed: number; maxStart: number; minSpeed: number; minStart: number }): RotationBehavior

  • Parameters

    • config: { accel: number; maxSpeed: number; maxStart: number; minSpeed: number; minStart: number }
      • accel: number

        Constant rotational acceleration of the particles, in degrees/second/second.

      • maxSpeed: number

        Maximum rotation speed of the particles, in degrees/second. Positive is counter-clockwise.

      • maxStart: number

        Maximum starting rotation of the particles, in degrees. 0 is facing right, 90 is upwards.

      • minSpeed: number

        Minimum rotation speed of the particles, in degrees/second. Positive is counter-clockwise.

      • minStart: number

        Minimum starting rotation of the particles, in degrees. 0 is facing right, 90 is upwards.

    Returns RotationBehavior

order

order: BehaviorOrder = BehaviorOrder.Normal

Order in which the behavior will be handled. Lower numbers are handled earlier, with an order of 0 getting special treatment before the Emitter's transformation is applied.
