Well, Asteroids can now have fuel! No actual coding required: the game treats them like parts, so all it takes is a few edits to a .cfg file Proof:http://imgur.com/q1n1P9r Now up: adding mined rock and a way of processing it. WaRi, if I could get the model, I might be able to finish this very soon. Edit: Added mined rock and raw minerals as resources. You can actually mine asteroids, turning the raw minerals into mined rock, which in turn is stored in tanks. Does this need its own thread?
