A-Life Simulator

Browser-based artificial life simulation built with TypeScript and Vite. Entities are made of colored line segments (Photosynth, Locomotor, Neural, Attack, Armor) and evolve through mutation and natural selection. Inspired by Primorial Life.

What it does

• Simulates populations of autonomous entities in a wrapped 2D world.
• Models energy, health, reproduction, combat, and nutrient-field interactions.
• Supports manual experimentation with live controls, presets, and overlays.
• Includes automation presets for running reproducible experiment batches.
• Exports results, census logs, mosaics, screenshots, and analysis artifacts.

Controls at a glance

• Click and drag to pan; scroll/pinch to zoom.
• Click an entity to inspect stats, genome, and relatives.
• Use Enable turbo, Sim steps per frame, and Sim step time to change simulation speed.
• Use Sliders & presets and Automation for tuning and batch runs.
