IsPointInPolygon()

proto bool IsPointInPolygon ( notnull array< float > polygon, float x, float y )

staticprivate

Check if a point is inside polygon.

Parameters

polygon	Must be an array of Vector2, every two consecutive floats represent one point in polygon.
x	X coordinate of point to test
y	Y coordinate of point to test

References x, and y.

IsPointInPolygonXZ()

proto bool IsPointInPolygonXZ ( notnull array< vector > polygon, vector point )

staticprivate

Check if a point is inside polygon.

Takes polygon and point only in the XZ plane.

IsPointInTriangleXZ()

proto bool IsPointInTriangleXZ ( vector p1, vector p2, vector p3, vector point )

staticprivate

Check if point is inside triangle specified by points p1, p2 and p3.

Math2D()

enum WindingOrder Math2D

Referenced by CfgPlayerRestrictedAreaHandler::IsPointInAreaPolygon(), and PlayerInsideOfLocationFilter().

TriangleWindingXZ()

proto WindingOrder TriangleWindingXZ ( vector a, vector b, vector c )

staticprivate

Determines winding order of triangle given by points a, b, c.

If the triangles form a line, WindingOrder.Invalid is returned.
