Settings steer or throttle to 0 doesn’t work. It just changes back to the old value. You can replicate this by manually setting the value to 0 through the properties window. Please fix this soon, I have a feeling that my winter game will rely on skateboardplatforms to fulfill the role of snowboards, and currently players can’t stop turning.
EDIT
I’ve been informed that Throttle and Steer are meant for reading and that I should be using ApplySpecificImpulse instead. Can’t say I’m terribly thrilled that we have writable properties that aren’t for writing.
