I'm trying to make a mod for KSP that calculates stuff, and I need to access a list of all engines that are unlocked. Then, I need to access instance variables of the engines, such as their ispVac, ispASL, thrustASL, and thrustVac. I don't know if you can tell, but I've scoured the API documentation for a little while looking for something like it. I'd prefer an array of just the 1.5m liquid fuel rocket engines, but I can make a new array if needed. Thanks.
I apologize if this isn't where it should be or is formatted incorrectly.
