First, use pcln instead of clne, as pcln creates 8 directions of phot every frame.
Second, use void to delete the photons in the 7 unwanted directions.
This is what it should look like:
O
VVV
PV
VVV
N
Where o is pscn, v is void, p is pcln, and n is nscn. The laser will fire left.
To create high-density lasers, make the PCLN/PBCN into this shape:
P PP
leaving a gapbetween two of them.
Heat up the beams with Maze or uranium+pump.... Works great forget the compressed stuff
