Field Detail

renderingShapeClasses

public static java.util.LinkedList<java.lang.Class<? extends RenderingShape>> renderingShapeClasses

strokeWidth

public java.lang.Double strokeWidth

sizeBox

public SizeBox sizeBox

Provides a rough measure of the size of a shape via a Rectangle, applicable height every subclass of shape

Two shapes with the same SizeBoxes should have roughly the same actual size in the final render.

Constructor Detail

RenderingShape

public RenderingShape(SizeBox s)

Creates a RenderingShape with sensible default values, so that the final size of the rendered shape has similar dimensions as the rectangle of the given SizeBox

Method Detail

isShape

public static boolean isShape(java.lang.String s)

setWidth

public void setWidth(double width)

setHeight

public void setHeight(double height)

render

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

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..)

Parameters:

gc - The graphics context on which the shape is rendered

label -

s - Stroke color

f - Filling color

render

public void render(GralogGraphicsContext gc,
                   Vector2D center,
                   GralogColor s,
                   GralogColor f)

containsCoordinate

public abstract boolean containsCoordinate(Vector2D point,
                                           Vector2D center)

Returns true if the given vector is overlapping with this shape

Parameters:

point - Vector that is being tested for overlapping

Returns:

True if the shape contains

getEdgePoint

public abstract 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.

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 abstract Vector2D getIntersection(Vector2D lineStart,
                                         Vector2D lineEnd,
                                         Vector2D center)

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

Parameters:

lineStart - Start of the line

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

center - The center of the object with this shape
