Hi. I'm trying to figure out how muscles work.
In the information, I find three hints about how muscles work.
1) "Muscles are spring-like, which means that they will always tend to go back into their starting position."
2) "The output is a floating point number between -1 and 1 which determines how far the muscles should expand/contract."
3) "A creature can expand and contract its muscles continuously by applying a different amount of force to them."
So what does the output change? How far the muscles contract? How much force the muscles apply? Or are these two things related? For example, if the muscles are like springs, it takes more force to stretch them farther, and subsequently they spring back with more force?
During the simulation, do the muscles keep firing at a constant rate?
Thanks for making this amazing simulator! My students love it.
