Struct JointBaseBuilder 

pub struct JointBaseBuilder { /* private fields */ }

Implementations

impl JointBaseBuilder

pub fn new() -> Self

Create a new base with identity local frames.

pub fn bodies<'w>(self, a: &Body<'w>, b: &Body<'w>) -> Self

Attach two bodies using scoped body handles.

pub fn bodies_by_id(self, a: BodyId, b: BodyId) -> Self

Attach two bodies by raw ids.

pub fn local_frames<VA: Into<Vec2>, VB: Into<Vec2>>( self, pos_a: VA, angle_a: f32, pos_b: VB, angle_b: f32, ) -> Self

Set local frames from positions and angles (radians).

pub fn collide_connected(self, flag: bool) -> Self

pub fn force_threshold(self, v: f32) -> Self

Force threshold for joint events.

pub fn torque_threshold(self, v: f32) -> Self

Torque threshold for joint events.

pub fn constraint_hertz(self, v: f32) -> Self

Advanced constraint tuning frequency in Hertz.

pub fn constraint_damping_ratio(self, v: f32) -> Self

Advanced constraint damping ratio.

pub fn draw_scale(self, v: f32) -> Self

pub fn local_frames_raw(self, a: b2Transform, b: b2Transform) -> Self

pub fn local_points_from_world<'w, V: Into<Vec2>>( self, body_a: &Body<'w>, world_a: V, body_b: &Body<'w>, world_b: V, ) -> Self

Set local anchor positions from world points (rotation remains identity).

pub fn build(self) -> JointBase

pub fn frames_from_world_with_axis<'w, VA, VB, AX>( self, body_a: &Body<'w>, anchor_a_world: VA, axis_world: AX, body_b: &Body<'w>, anchor_b_world: VB, ) -> Self

where VA: Into<Vec2>, VB: Into<Vec2>, AX: Into<Vec2>,

Set local frames using world anchors and a shared world axis (X-axis of joint frame). This computes localFrameA/B.rotation so that their X-axis aligns with the given world axis, and localFrameA/B.position to the given world anchor points.
