In here, you'll see, well, simulated bacteria! The sim starts with six bacteria, represented with pen dots. There are three red particles and three blue particles. All these particles share the same rule, or, DNA you could say: "If i'm near a particle just like me, I want to move away." "But if i'm near a different particle, I want to move towards them." However... Moving costs energy. The longer a particle exists, the more energy it loses! If it loses all its energy. It will disappear. If a particle is next to a different particle, they both gain energy! I guess you can say that's symbiosis. And if a particle has maxed out its energy, it duplicates!!! Now we have a full ecosystem in one scratch project. Try clicking. You can spawn some green bacteria, watch how it interacts! Any simulator ideas i should do next? I have done quantum physics, classical physics, optics, and now biology!
