Méthode Description
AsRay ( ) : Microsoft.Xna.Framework.Ray
ClosestPointTo ( Point point ) : Point
CollideAgainst ( Polygon polygon ) : bool
DistanceTo ( AxisAlignedRectangle rectangle ) : float
DistanceTo ( Microsoft.Xna.Framework.Circle circle ) : float
DistanceTo ( Point point ) : float
DistanceTo ( Point point, Segment &connectingSegment ) : float
DistanceTo ( Point point, Microsoft.Xna.Framework.Vector3 &connectingVector ) : float

Returns the distance to the argument point as well as the connectin Vector3 from the Point to this.
DistanceTo ( Polygon polygon ) : float
DistanceTo ( Segment otherSegment ) : float
DistanceTo ( Microsoft.Xna.Framework.Vector3 vector ) : float
DistanceTo ( double x, double y ) : float
DistanceToSquared ( Microsoft.Xna.Framework.Vector3 &vector, Segment &connectingSegment ) : float
GetLength ( ) : double

Returns the length of the segment.
GetLengthSquared ( ) : double
IntersectionPoint ( Segment &s2, Point &intersectionPoint ) : void

Returns the point where this segment intersects the argument segment.
Intersects ( Segment s2 ) : bool

Determines whether this segment intersects the argument segment.
Intersects ( Segment s2, Point &intersectionPoint ) : bool
IsClosestPointOnEndpoint ( Point &point ) : bool

Determines whether the closest point on the segment lies on one of the endpoints.
IsParallelAndTouching ( Segment s2, Point &intersectionPoint ) : bool
MoveBy ( float x, float y ) : void

Shifts the segment by moving both points by the argument x,y values.
Normalize ( ) : void

Sets the length of the segment to 1 unit by moving the 2nd point.

If the segment has 0 length (the endpoints are equal), the method does not change the segment; length will remain 0.

Segment ( Microsoft.Xna.Framework.Graphics.VertexPositionColor &point1, Microsoft.Xna.Framework.Graphics.VertexPositionColor &point2 ) : System
Segment ( Point point1, Point point2 ) : System

Creates a new Segment with the argument points as the endpoints.
