Function Documentation

IsPointInPolygon()

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

static

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

IsPointInPolygonXZ()

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

static

Check if a point is inside polygon. Takes polygon and point only in the XZ plane.

IsPointInTriangleXZ()

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

static

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

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

TriangleWindingXZ()

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

static

Determines winding order of triangle given by points a, b, c. If the triangles form a line, WindingOrder.Invalid is returned.
