With this update, it is now possible to configure pistons as springs instead. Springs have adjustable stiffness, and will pull the connected axle toward the end or the center of their motion range.
We are also adding 2 blueprints to showcase this feature:
"Crossbow", which can be manually loaded and fired:
and "Buggy", which is a vehicle with suspensions.
Completed builds will be uploaded to the workshop soon.
