Alright, I've been running a randombot sim on my laptop for a week, 30 heterotrophs, each with unique random numbers that I started with. Today I found a bot that was shooting constantly but no shooting costs were applied. I had set it to 0.64. It has always worked but today I discovered that I had to set it above 1 for any cost to be applied. If I set it to 1 or lower it shoots for free.
I was thinking maybe it was a temporary glitch, so I thought I should try this bot on my stationary computer. I copied the dna over and started a number of this bot together with some veggies and what do I see? The bots come alive! While they constantly shoots they sometimes swims and sometimes floot around! On my laptop this bot was constantly fixed! So just by picking one bot and start a new sim with it you can get different behavior from the same DNA!
I've also discovered that on my laptop costs are rounded down (0.64 becomes 0) while on my stationary they are rounded up (0.64 becomes 1)!
I know that the GUI's in DB are somewhat depended on the computers language settings for values, but Eric fixed that for the cost GUI, but maybe there is something else causing the difference in rounding.
It seems Morphological Costs were rounded since version 2.43.1L, maybe earlier than that which I've somehow missed. Anything from 1 and higher for movement and shooting is too aggressive imo. The oddity with my laptop is that I must set the cost ABOVE 1 to get any cost at all, like 1.001 for instance.
Fortunately the Cost Multiplier isn't rounded so I can lower that instead. I didn't know this until today so I've been running sims with either too aggressive costs or no costs at all! Argh!
Here's the bot DNA if you want to check it out:
