day and night vision...

[Drognan]

Is it possible that during night period vision becames weaker? Like in real life, maybe we could develop new bot species that would "come out" only during the night. During daytime they would seek shelter from daytime species and vice versa...

[Numsgil]

A good idea.  Would make day/night cycles more interesting certainly.

How vision affects to energy consumption? In real life vision is very energy demanding, so maybe bots with vision disabled will have advantage in lower energy needs.

[Houshalter]

How is it energy demanding? It takes up some resources and demands alot of brain power to proccess it. It also gives a species a weakness, but, unless you have laser eyes, it doesn't take that much energy to maintain.

[Numsgil]

At the moment there's nothing in the engine to reward bots that don't use vision.  Real life aside, it would probably be a good idea to add just for the fact that bots that don't use vision are cheaper to simulate.

Vision strength could be dependent on an optic material...

remember, in real life, the only nocturnal benefit is to avoid certain diurnal predators, or to coincide with the activity period of nocturnal prey. Poor eyesight just means that a species doesn't rely much on vision, so the degeneration of 'eye genes' has a relatively small effect on the fitness of an individual.
