Class AccelerationBehavior

A Movement behavior that handles movement by applying a constant acceleration to all particles.

Example configuration:

{
    "type": "moveAcceleration",
    "config": {
         "accel": {
              "x": 0,
              "y": 2000
         },
         "minStart": 600,
         "maxStart": 600,
         "rotate": true
    }
}

constructor

  • new AccelerationBehavior(config: { accel: { x: number; y: number }; maxSpeed?: number; maxStart: number; minStart: number; rotate?: boolean }): AccelerationBehavior

  • Parameters

    • config: { accel: { x: number; y: number }; maxSpeed?: number; maxStart: number; minStart: number; rotate?: boolean }
      • accel: { x: number; y: number }

        Constant acceleration, in the coordinate space of the particle parent, in world units/second.

        • x: number
        • y: number
      • Optional maxSpeed?: number

        Maximum linear speed. 0 is unlimited. Defaults to 0.

      • maxStart: number

        Maximum speed when initializing the particle. in world units/second.

      • minStart: number

        Minimum speed when initializing the particle, in world units/second.

      • Optional rotate?: boolean

        Rotate the particle with its direction of movement. While initial movement direction reacts to rotation settings, this overrides any dynamic rotation. Defaults to false.

    Returns AccelerationBehavior

Properties

Private accel

accel: { x: number; y: number }

Type declaration

  • x: number
  • y: number

Private maxSpeed

maxSpeed: number

Private maxStart

maxStart: number

Private minStart

minStart: number

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.
