I am currently using HingeConstraints to rotate my wheels, but this makes them all wobblily and the general car stability is low. How can I best fix this? I’m okay with snapping wheels and just not using constraints if its easier than other options. But even then, my method of snapping wheels had problems too. I’m wondering if this is a easy fix or not.
Wobblily wheels:
Driving around:
Mess with the density properties in custom physical properties of your chassis, mainly the hinges and what’s connected. Then mess with the servo settings of the hinge.
High density, but not too high is what worked for my past 5+ car chassis I’ve made.
Changing the density helped a bit but I still have the wobblily wheels issue.
Try increasing the servo’s torque or making the wheels heavier
Dumb answer (because IDK if you tried it yet) but maybe you could try setting (partially of) the car to a diff. collision group or just remove collision in that area because It looks like it’s just rubbing up against something causing the wobbly wheels.
There are so many posts that deal with car steering that’s wobbly. I’d suggest searching those before posting.
Try setting Restitution to 1 instead of 0 (just an experiment, the documentation says it’s constrained between 0 and 1 for the elasticity of the hinge at it’s limits, but doesn’t say if setting it to 0 is more springy or less springy…).
Increase your ServoMaxTorque to something like 1,000,000. If it isn’t high enough it won’t hold the wheels at the angle you want when it’s dealing with driving forces.
Move the steering hinge point to the center of the wheel. Otherwise the force of the tire pushing forward or backward will try to twist the steering hinge.
With my cars I also add a RodConstraint to 2 Attachments directly in front of or behind the steering hinge, offset by about 2 studs. It’ll help keep both hinges at the same angle at all times.
