class bruhanimate.bruheffect.automaton_effect.AutomatonEffect(buffer: Buffer, background: str, settings: AutomatonSettings = None)[source]¶

Bases: BaseEffect

Wolfram 1-D elementary cellular automaton.

Each generation is computed from the previous row using a 3-cell neighbourhood lookup table determined by the rule number (0–255). New generations scroll downward from the top, producing a 2-D space-time diagram. Rule 30 (default) is chaotic; Rule 90 produces Sierpinski triangles; Rule 110 is Turing-complete.

Call set_rule() to switch rules and reset the seed mid-run.

__init__(buffer: Buffer, background: str, settings: AutomatonSettings = None)[source]¶

Base class for all effects.

Parameters:

  • buffer (Buffer) – Effect buffer to push updates to.

  • background (str) – character or string to use for the background.

set_rule(rule_num: int)[source]¶

Switch to a new rule number (0–255) and reset the initial seed.

render_frame(frame_number: int)[source]¶

To be defined by each effect.
