A Ray is a line that starts in its centre and radiates out to an infinite length unless it collides with other shapes.
Collision Shapes - Connect Shapes to be used as collisions.
Collision Margin - Increase/ decrease the depth of a collision.
Bidirectional - When checked, the Ray will travel out from its centre in both directions along a horizontal axis.
Divisions - Set the number of divisions along the length of the Ray.
