Rule:Bullets

@RULE Bullets Uploaded by Redstoneboi#9534 on Discord > A simple, Turing-complete, particle-based rule.

1. "Bullets was *really* low hanging fruit."
2. "Like, it's unbelievable nobody's thought about it before."
3. "I mean, there's WireWorld, but, the mechanics aren't really that intuitive for me, at least."
4. -Redstoneboi, the guy who made this rule
6. A 3-2 pair is a photon, or "bullet", that travels straight in a direction until it hits something.
7. When it hits something, it splits in 2 if it can.
8. If it hits another bullet, they cancel out.
9. Splitting takes priority over cancellation. This is a side effect of the simplicity of the rule.
11. This means simple reflectors, splitters, eaters, OR and ANDNOT gates,
12. even semi-crossovers since it's particle based (like Conway's Game of Life).
