Public Attributes

Vector2 normal

Detailed Description

A border object: a line that delimitates a semiplane in the simulation space. The line has infinite length; it is defined by one point belonging to the line and the normal to this line, oriented towards the interior (the zone where the simulated objects evolve). The location of the reference point r on the line does not matter.
