public bool Contains (Vector2 point);
public bool Contains (Vector3 point);
public bool Contains (Vector3 point, bool allowInverse);

Parameters

pointPoint to test.
allowInverseDoes the test allow the Rect's width and height to be negative?

Returns

bool True if the point lies within the specified rectangle.

Description

Returns true if the x and y components of point is a point inside this rectangle. If allowInverse is present and true, the width and height of the Rect are allowed to take negative values (ie, the min value is greater than the max), and the test will still work.
