So if this thing kills bots with high Body, all the offspring are gonna have low body, right? Or am I completely and utterly wrong?
No it kills bots with less body than it has
Perhaps I should have explained better.
If you have a bot programmed to
10 .repro store at 20000 Energy, then when it reaches 20000 Energy, it'll produce an offspring with 2000 Energy and 10% of its own body. So if it has 10 body the kid will have 1 body, if it has 1000 body the kid'll have 100.
Now, if this bot I'm making (who I'll refer to as Genocidis Darwini from here on out) eats all the bots of a certain species with more than, say, 10000 Body before they can reproduce, then the survivors (the ones with low Body) will all produce offspring with low body, and so on and so forth.
...if, of course, I am correct in my many assumptions.
