In DB2 bots can join together to be MB's...And they just are a cluster, but what about little chains in bots, with a certain range (determined in DNA...Default 0 range so mutations can add range to it) then via that connection they can send these simple primative signals (unless an override is put into the code)
FoodF - Food Found
FoodN - No Food
Shpe - Shape
FoodTShape - Food Through Shape (If bots can see through shape (so if the shape is transparent))
VegTShape - Like FoodTShape but with veggies
Bad - Danger Found (Virus, same species corpses or a KNOWN PREDATOR (Library inside each bot containing list of species which are either - Mutual, Friendly, Food, Enemy))
Veg - Veg found (Not to be confused with food found as thats a 'food' bot)
PFound - Path Found (Only returned after FoodTShape/VegTShape if the veg/food in question is seen without obstruction.
Then on the end of FoodF, Veg, Bad or FoodTShape would be:
~h - High
~m - Medium
~l - Low
It litterally then either triggers bot to go in that direction, or away from that direction
It'd make multibots cooler, or hotter, depends on their enviroment which they want to be
