Title: Morphological costs applied before the bot can move!
Post by: Testlund on February 06, 2008, 04:37:54 PM: I was trying to start a sim with zerobots here and discovered that costs for movement are applied if they are set in the costs tab, despite that the bot has no genes for movement!
I also found that the minimum value I could have for veggies per kilobody point set to not immedeately kill the bot is no less than 12. My morphological costs were set to 0.8 for movement and spinning. Once I set the morphological costs to 0 the bot wasn't charged any energy. But it shouldn't get charged for something it can't use!

Here's the sim:
