Syntax

public class RecursiveShadowcastingSenseSource : SenseSourceBase, ISenseSource

Remarks

Any location on the resistance map which is not fully blocking (eg. has a value less than the source's Intensity) is considered to be fully transparent, because this implementation of shadow-casting is an on-off algorithm.

This calculation is faster but obviously doesn't offer support for partial resistance. It may be useful when you only want a rough light approximation, or where your resistance map is on-off anyway.

Constructors

RecursiveShadowcastingSenseSource(Point, double, Distance, double)

Creates a source which spreads outwards in all directions.

Declaration

public RecursiveShadowcastingSenseSource(Point position, double radius, Distance distanceCalc, double intensity = 1)

Parameters

Type	Name	Description
Point	position	The position on a map that the source is located at.
double	radius	The maximum radius of the source -- this is the maximum distance the source values will emanate, provided the area is completely unobstructed.
Distance	distanceCalc	The distance calculation used to determine what shape the radius has (or a type implicitly convertible to Distance, such as Radius).
double	intensity	The starting intensity value of the source. Defaults to 1.0.

RecursiveShadowcastingSenseSource(Point, double, Distance, double, double, double)

Constructor. Creates a source which spreads only in a cone defined by the given angle and span.

Declaration

public RecursiveShadowcastingSenseSource(Point position, double radius, Distance distanceCalc, double angle, double span, double intensity = 1)

Parameters

Type	Name	Description
Point	position	The position on a map that the source is located at.
double	radius	The maximum radius of the source -- this is the maximum distance the source values will emanate, provided the area is completely unobstructed.
Distance	distanceCalc	The distance calculation used to determine what shape the radius has (or a type implicitly convertible to Distance, such as Radius).
double	angle	The angle in degrees that specifies the outermost center point of the cone formed by the source's values. 0 degrees points right.
double	span	The angle, in degrees, that specifies the full arc contained in the cone formed by the source's values -- angle / 2 degrees are included on either side of the cone's center line.
double	intensity	The starting intensity value of the source. Defaults to 1.0.

RecursiveShadowcastingSenseSource(int, int, double, Distance, double)

Creates a source which spreads outwards in all directions.

Declaration

public RecursiveShadowcastingSenseSource(int positionX, int positionY, double radius, Distance distanceCalc, double intensity = 1)

Parameters

Type	Name	Description
int	positionX	The X-value of the position on a map that the source is located at.
int	positionY	The Y-value of the position on a map that the source is located at.
double	radius	The maximum radius of the source -- this is the maximum distance the source values will emanate, provided the area is completely unobstructed.
Distance	distanceCalc	The distance calculation used to determine what shape the radius has (or a type implicitly convertible to Distance, such as Radius).
double	intensity	The starting intensity value of the source. Defaults to 1.0.

RecursiveShadowcastingSenseSource(int, int, double, Distance, double, double, double)

Constructor. Creates a source which spreads only in a cone defined by the given angle and span.

Declaration

Parameters

Type	Name	Description
int	positionX	The x-value for the position on a map that the source is located at.
int	positionY	The y-value for the position on a map that the source is located at.
double	radius	The maximum radius of the source -- this is the maximum distance the source values will emanate, provided the area is completely unobstructed.
Distance	distanceCalc	The distance calculation used to determine what shape the radius has (or a type implicitly convertible to Distance, such as Radius).
double	angle	The angle in degrees that specifies the outermost center point of the cone formed by the source's values. 0 degrees points right.
double	span	The angle, in degrees, that specifies the full arc contained in the cone formed by the source's values -- angle / 2 degrees are included on either side of the cone's center line.
double	intensity	The starting intensity value of the source. Defaults to 1.0.
