I'm looking for a classic Ray. To take up less space, I need a Ray that will pass through the LED in any state (diagonally), excluding ins. Activation or spark should only occur at the intersection of two Rays.
behavior? - Two Brays is not suitable.

* Like chess.

* And it is not intersection. - see dot production.

Appendices: An error occurs. It affects the LED nearby(see example)

There must be: Dray(draw) => aray line. Dot product => Bray(bricked dot). Pscn bray ray, nscn cray line(cleaner a ray, forced). Draw => entity line(ctype and auto). Else names: dlne(draw line - through entity by collision confirm-ctype)

Bray is Logic Member (but at this time transparent). There must be a cache store item.
