Life Form Simulator AI

Assembling a Body from Parts

Life Form Simulator AI begins with an empty canvas and a library of modular components. Bones form the rigid frame, muscles generate force for motion, and joints allow bending and rotation. You click to select a part, then connect it to another. There is no cap on part count, so a creature can be as simple as a stick figure or as involved as a multi-limbed structure. Every attachment point affects how the finished organism will move.

Evolution Through Movement Tasks

After assembly, you pick a goal: walking forward, running faster, or jumping over an obstacle. The simulation starts, and a neural network drives the creature's actions. A genetic algorithm then adjusts that network over many generations. Small variations appear each cycle; effective movements are reinforced while ineffective ones fade. Across hundreds or thousands of generations, the creature improves at its assigned task. You watch speed, balance, and coordination develop in real time.

Physics as a Design Constraint

A physics engine governs how the creature interacts with its environment. Gravity pulls it down, friction determines how feet grip the ground, and momentum carries it forward. Joints have bend limits, and muscles produce only so much force. A poorly designed body struggles. Long legs cover ground but tip easily; a low, wide body is stable but slow. The system rewards thoughtful construction and exposes haphazard choices.

Experimentation and Learning

No single correct build exists. You can imitate natural shapes like a four-legged animal or a hopping frog, or invent something without a real-world counterpart. Visual feedback shows which parts move well and which cause problems. You can pause, adjust the design, and restart evolution at any point. Because each design learns differently, no two runs play out the same way. The game runs in a desktop browser with full-screen support and no time pressure.
