Expand description

Wheel joint definition Body B is a wheel that may rotate freely and slide along the local x-axis in frame A. The joint translation is zero when the local frame origins coincide in world space. @ingroup wheel_joint

Fields§

§enableLimit: bool

Enable/disable the joint linear limit

§lowerTranslation: f32

The lower translation limit
