Expand description

Base joint definition used by all joint types. The local frames are measured from the body’s origin rather than the center of mass because:

you might not know where the center of mass will be
if you add/remove shapes from a body and recompute the mass, the joints will be broken

Fields§

§userData: *mut c_void

User data pointer

§bodyIdA: b2BodyId

The first attached body

§bodyIdB: b2BodyId

The second attached body

§localFrameA: b2Transform

The first local joint frame

§localFrameB: b2Transform

The second local joint frame

§forceThreshold: f32

Force threshold for joint events

§torqueThreshold: f32

Torque threshold for joint events

§constraintHertz: f32

Constraint hertz (advanced feature)

§constraintDampingRatio: f32

Constraint damping ratio (advanced feature)

§drawScale: f32

Debug draw scale

§collideConnected: bool

Set this flag to true if the attached bodies should collide
