Метод	Описание
Polygon ( Vector2 points ) : System	constructs a Polygon from points. points should be specified in clockwise fashion without duplicating the first/last point and they should be centered around 0,0.
Polygon ( int vertCount, float radius ) : System	creates a symmetrical polygon based on the radius and vertCount passed in
buildEdgeNormals ( ) : void	builds the Polygon edge normals. These are lazily created and updated only by the edgeNormals getter
buildSymmetricalPolygon ( int vertCount, float radius ) : Vector2[]	builds a symmetrical polygon (hexagon, octogon, n-gon) and returns the points
collidesWithLine ( Vector2 start, Vector2 end, RaycastHit &hit ) : bool
collidesWithShape ( Shape other, CollisionResult &result ) : bool
containsPoint ( Vector2 point ) : bool	essentially what the algorithm is doing is shooting a ray from point out. If it intersects an odd number of polygon sides we know it is inside the polygon.
findPolygonCenter ( Vector2 points ) : Vector2	finds the center of the Polygon. Note that this will be accurate for regular polygons. Irregular polygons have no center.
getClosestPointOnPolygonToPoint ( Vector2 points, Vector2 point, float &distanceSquared, Vector2 &edgeNormal ) : Vector2	iterates all the edges of the polygon and gets the closest point on any edge to point. Returns via out the squared distance to the closest point and the normal of the edge it is on. point should be in the space of the Polygon (point - poly.position)

Описание методов

Polygon() публичный Метод

constructs a Polygon from points. points should be specified in clockwise fashion without duplicating the first/last point and they should be centered around 0,0.

public Polygon ( Vector2 points ) : System
points	Vector2	Points.
Результат	System

Polygon() публичный Метод

creates a symmetrical polygon based on the radius and vertCount passed in

public Polygon ( int vertCount, float radius ) : System
vertCount	int	Vert count.
radius	float	Radius.
Результат	System

buildEdgeNormals() публичный Метод

builds the Polygon edge normals. These are lazily created and updated only by the edgeNormals getter

public buildEdgeNormals ( ) : void
Результат	void

buildSymmetricalPolygon() публичный статический Метод

builds a symmetrical polygon (hexagon, octogon, n-gon) and returns the points

public static buildSymmetricalPolygon ( int vertCount, float radius ) : Vector2[]
vertCount	int	Vert count.
radius	float	Radius.
Результат	Vector2[]

collidesWithLine() публичный Метод

public collidesWithLine ( Vector2 start, Vector2 end, RaycastHit &hit ) : bool
start	Vector2
end	Vector2
hit	RaycastHit
Результат	bool

collidesWithShape() публичный Метод

public collidesWithShape ( Shape other, CollisionResult &result ) : bool
other	Shape
result	CollisionResult
Результат	bool

containsPoint() публичный Метод

essentially what the algorithm is doing is shooting a ray from point out. If it intersects an odd number of polygon sides we know it is inside the polygon.

public containsPoint ( Vector2 point ) : bool
point	Vector2	Point.
Результат	bool

findPolygonCenter() публичный статический Метод

finds the center of the Polygon. Note that this will be accurate for regular polygons. Irregular polygons have no center.

public static findPolygonCenter ( Vector2 points ) : Vector2
points	Vector2	Points.
Результат	Vector2

getClosestPointOnPolygonToPoint() публичный статический Метод

iterates all the edges of the polygon and gets the closest point on any edge to point. Returns via out the squared distance to the closest point and the normal of the edge it is on. point should be in the space of the Polygon (point - poly.position)

public static getClosestPointOnPolygonToPoint ( Vector2 points, Vector2 point, float &distanceSquared, Vector2 &edgeNormal ) : Vector2
