class: PhysicsUnitConverter

[23:7] extends: FxObj

Wraps FXGL's PhysicsUnitConverter (com.almasb.fxgl.physics.PhysicsUnitConverter), the interface that converts between JavaFX pixel units and jbox2d meter units. Box2D's solver works in meters; FXGL keeps gameplay code in pixels and uses a converter to bridge the two whenever a Body or Fixture is constructed. The default converter scales at 50 pixels per meter; the engine exposes the live converter through the PhysicsWorld. Aussom users do not construct one directly; obtain it from physicsWorld.getJBox2DWorld() or use the unit-aware helpers on BoundingShape / Body.

Methods

PhysicsUnitConverter ()

Empty default constructor; populated by adopt.
adopt (object Ajo)

Wraps an existing PhysicsUnitConverter AussomJavaObject.
- @p Ajo is an AussomJavaObject around a PhysicsUnitConverter.
- @r A new wrapper.
toMeters (double Pixels)

Converts a pixel value to box2d meters.
- @p Pixels is a double pixel value.
- @r A double in meters.
toPixels (double Meters)

Converts a meter value to pixels.
- @p Meters is a double meter value.
- @r A double in pixels.
toPoint (object PointAjo)

Converts a Point2D (pixel coords) to a Vec2 (meter coords).
- @p PointAjo is a javafx.geometry.Point2D AJO.
- @r A Vec2 wrapper in meters.
toPixelPoint (object VecObj)

Converts a Vec2 (meter coords) to a Point2D (pixel coords).
- @p VecObj is a Vec2 wrapper.
- @r A javafx.geometry.Point2D AJO.
toVector (object PointAjo)

Converts a Point2D (pixel coords) to a Vec2 (meter coords) via the toVector overload (alias of toPoint with the same semantics but takes a Point2D).
- @p PointAjo is a javafx.geometry.Point2D AJO.
- @r A Vec2 wrapper in meters.
