Method Summary

Modifier and Type	Method	Description
boolean	containsCoordinate(Vector2D point, Vector2D center)	Returns true if the given vector is overlapping with this shape
Vector2D	getEdgePoint(double alpha, Vector2D center)	Calculates the (closest) point X on the edge of the shape so that (X-center) has an euler angle of alpha.
Vector2D	getIntersection(Vector2D a, Vector2D b, Vector2D center)	Calculates the point of intersection between a line and the shape (Basically a RayCast)
void	render(GralogGraphicsContext gc, Vector2D center, java.lang.String label, GralogColor strokeColor, GralogColor fillColor)	Renders a shape on the provided graphics context.

Method Detail

render

public void render(GralogGraphicsContext gc,
                   Vector2D center,
                   java.lang.String label,
                   GralogColor strokeColor,
                   GralogColor fillColor)

Description copied from class: RenderingShape

Renders a shape on the provided graphics context. RenderingShape will depend on the internal state of the shape object (e.g. parameters such as size, fill, color, etc..)

Overrides:

render in class RenderingShape

Parameters:

gc - The graphics context on which the shape is rendered

strokeColor - Stroke color

fillColor - Filling color

containsCoordinate

public boolean containsCoordinate(Vector2D point,
                                  Vector2D center)

Description copied from class: RenderingShape

Returns true if the given vector is overlapping with this shape

Specified by:

containsCoordinate in class RenderingShape

Parameters:

point - Vector that is being tested for overlapping

Returns:

True if the shape contains

getEdgePoint

public Vector2D getEdgePoint(double alpha,
                             Vector2D center)

Description copied from class: RenderingShape

Calculates the (closest) point X on the edge of the shape so that (X-center) has an euler angle of alpha.

Specified by:

getEdgePoint in class RenderingShape

Parameters:

alpha - The angle of the point in degrees

center - The point of reference for calculating X

Returns:

The closest such point as a Vector2D

getIntersection

public Vector2D getIntersection(Vector2D a,
                                Vector2D b,
                                Vector2D center)

Description copied from class: RenderingShape

Calculates the point of intersection between a line and the shape (Basically a RayCast)

Specified by:

getIntersection in class RenderingShape

Parameters:

a - Start of the line

b - The end of the line INSIDE the shape. For a normal edge calculation, lineEnd = center

center - The center of the object with this shape
