Class SpeedBehavior

A Movement behavior that uses an interpolated or stepped list of values for a particles speed at any given moment. Movement direction is controlled by the particle's starting rotation.

Example config:

{
    type: 'moveSpeed',
    config: {
         speed: {
             list: [{value: 10, time: 0}, {value: 100, time: 0.25}, {value: 0, time: 1}],
         },
         minMult: 0.8
    }
}

  • Parameters

    • config: { minMult: number; speed: ValueList<number> }
      • minMult: number

        A value between minimum speed multipler and 1 is randomly generated and multiplied with each speed value to generate the actual speed for each particle.

      • speed: ValueList<number>

        Speed of the particles in world units/second, with a minimum value of 0

    Returns SpeedBehavior

order

order: BehaviorOrder = BehaviorOrder.Late

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.
