Class ProjectileMovement

constructor

• new ProjectileMovement(cfg?): ProjectileMovement

• Construct a movement policy that is appropriate for projectiles

  Parameters

  • cfg: {
        fixedVectorVelocity?: number;
        multiplier?: number;
        rotateVectorToss?: boolean;
    } = {}

    • Optional fixedVectorVelocity?: number

      A fixed velocity for all projectiles

    • Optional multiplier?: number

      A multiplier on projectile speed

    • Optional rotateVectorToss?: boolean

      Should projectiles be rotated in the direction they are tossed?

  Returns ProjectileMovement

Optional fixedVectorVelocity

multiplier

Optional rotateVectorToss

rigidBody

• set rigidBody(body): void

• The body of the actor to which this movement is attached

  Parameters

  • body: undefined | RigidBodyComponent

  Returns void

prerender

• prerender(_elapsedMs, _camera): void

• Do any last-minute adjustments related to the movement

  Parameters

  • _elapsedMs: number

  • _camera: CameraService

  Returns void

tossAt

• tossAt(from, fromX, fromY, toX, toY, offsetX, offsetY): void

• Toss a projectile. This is for tossing in the direction of a specified point. This method just handles movement. You shouldn't call it on your own. Use the Role's tossAt() method instead.

  Parameters

  • from: b2Vec2

  • fromX: number

    X coordinate of the center of the actor doing the toss

  • fromY: number

    Y coordinate of the center of the actor doing the toss

  • toX: number

    X coordinate of the point at which to toss

  • toY: number

    Y coordinate of the point at which to toss

  • offsetX: number

    The x distance between the center of the projectile and the center of the actor tossing the projectile

  • offsetY: number

    The y distance between the center of the projectile and the center of the actor tossing the projectile

  Returns void

tossFrom

• tossFrom(from, velocityX, velocityY): void

• Toss a projectile. This is for tossing in a single, predetermined direction. This method just handles movement. You shouldn't call it on your own. Use the Role's tossFrom() method instead.

  Parameters

  • from: b2Vec2

    The initial position

  • velocityX: number

    The X velocity of the projectile when it is tossed

  • velocityY: number

    The Y velocity of the projectile when it is tossed

  Returns void

updateVelocity

• updateVelocity(x, y): void

• Set a new velocity for the actor

  Parameters

  • x: number

  • y: number

  Returns void
