class: ProjectileComponent

[17:7] extends: Component

Wraps FXGL's ProjectileComponent (com.almasb.fxgl.dsl.components.ProjectileComponent), a DSL Component that translates the entity each tick along a Point2D direction at a given speed. Automatically rotates the entity to face the direction of motion (0 degrees assumed to face right).

Methods

ProjectileComponent (double Dx = 1.0, double Dy = 0.0, double Speed = 1.0)

Creates a new ProjectileComponent. Pass (Dx, Dy, Speed) to set the initial direction vector and speed; with no arguments uses (1.0, 0.0) facing right at 1.0.
- @p Dx is the X component of the initial direction.
- @p Dy is the Y component of the initial direction.
- @p Speed is the initial speed in pixels per second.
adopt (object Ajo)

Wraps an existing ProjectileComponent AussomJavaObject.
getVelocity ()

Returns the velocity Point2D AJO (direction.normalize() * speed).
getDirection ()

Returns the direction Point2D AJO (velocity.normalize()).
setDirection (double Dx, double Dy)

Sets the direction of motion. The direction vector is normalized internally and scaled by the current speed.
- @p Dx is the X component of the direction.
- @p Dy is the Y component of the direction.
- @r this object
getSpeed ()

Returns the current speed (double).
setSpeed (double Speed)

Sets the speed.
- @p Speed is the speed in pixels per second.
- @r this object
speedProperty ()

Returns the DoubleProperty for speed (binding-friendly).
allowRotation (bool AllowRotation)

Enables or disables auto-rotation toward the direction of travel.
- @p AllowRotation true to enable rotation.
- @r this object
