AbstractWormhole2D

abstract class AbstractWormhole2D<P : Position2D<out P>?> : Wormhole2D<P> (source)

Partial, abstract, implementation for the interface Wormhole2D. This implementation considers the particular case of the view as an entity into the sceern-space: the y-axis grows on the bottom side of the screen. This abstract class is independent from the 2D graphical component wrapped.

Parameters

<P>

the position type

Constructors

AbstractWormhole2D

constructor(@Nonnull environment: Environment<out Any, P>, @Nonnull view: T, @Nonnull viewTypeToPointAdapter: (T) -> PointAdapter<P>)

Properties

Functions

open fun center()

Points the center of the view on the center of the environment.

open fun getEnvPoint(viewPoint: Point): P

Converts a point from the view-space to the env-space.

open fun getViewPoint(envPoint: P): Point

Converts a point from the env-space to the view-space.

getViewPosition

open fun getViewPosition(): Point

Gets the Position.

open fun getViewSize(): Dimension2D

Gets the view's size.

open fun isInsideView(viewPoint: Point): Boolean

Check if a point of the view-space is "visible", i.e.

open fun optimalZoom()

Automatically sets the zoom rate in order to make the environment entirely visible on the view.

rotateAroundPoint

open fun rotateAroundPoint(p: Point, a: Double)

Rotates around a point into the view-space.

open fun setEnvPosition(envPoint: P)

Sets the position to the view-point corresponding to envPoint.

abstract fun setRotation(rad: Double)

Rotates the environment around the Position.

setViewPosition

open fun setViewPosition(viewPoint: Point)

Sets the Position to viewPoint.

abstract fun setZoom(value: Double)

Changes the zoom factor.

open fun zoomOnPoint(point: Point, zoomRate: Double)

Zooms on a point into the view-space.
