Public Member Functions
override Collider	DeepCopy ()
	PolygonSeperatedAxisCollider (Vector2[] vertices)
override bool	ContainsPoint (Vector2 point, out Vector2 closestPoint)
override void	Draw (SpriteBatch spriteBatch, PrimitiveBatch primitiveBatch)
	Draws the collider.
Public Member Functions inherited from PhysicsCSAlevlProject.Collider
bool	ContainsPoint (Vector2 point, out Vector2 closestPoint)
	Determines if the given point is contained within the collider and calculates the closest point on the collider to the given point. This method is used for collision detection and response, allowing the application to determine if a particle or object is colliding with the collider and to find the nearest point on the collider's surface for accurate physics interactions. The method returns true if the point is inside the collider, and false otherwise, while also providing the closest point on the collider as an output parameter. it outputs the same point if the point is outside the collider, which is used for calculating the collision response direction and magnitude based on how far the point is from the collider's surface.
Collider	DeepCopy ()
	Creates a deep copy of the collider,.

Public Attributes
Vector2[]	Vertices
	the vertices of the polygon collider defined in local space
Vector2[]	worldVertices
	the vertices of the polygon collider defined in world space

Properties
override Vector2	Position [get, set]
	the position of the polygon collider, which is the center point of the polygon. When the position is set, it updates the position of the polygon used for drawing and recalculates the vertices and axes of the polygon based on the new position.
float	angle [get, set]
	the angle of the polygon collider in radians, which determines the rotation of the polygon. When the angle is set, it updates the rotation of the polygon used for drawing and recalculates the vertices and axes of the polygon based on the new angle.
Properties inherited from PhysicsCSAlevlProject.Collider
virtual Vector2	Position [get, set]
