Struct PyConstraint 

pub struct PyConstraint {
    pub handle: u32,
    pub constraint_type: ConstraintType,
    pub body_a: u32,
    pub body_b: u32,
    pub anchor_a: [f64; 3],
    pub anchor_b: [f64; 3],
    pub target_distance: f64,
    pub axis: [f64; 3],
    pub stiffness: f64,
    pub enabled: bool,
}

A constraint between two rigid bodies.

Constraints are stored in the world and resolved during each step. Currently implemented as soft position-level corrections.

Fields

handle: u32

Unique handle.

constraint_type: ConstraintType

Type of constraint.

body_a: u32

Handle of the first body.

body_b: u32

Handle of the second body.

anchor_a: [f64; 3]

Anchor point on body_a in local coordinates (or world if no body).

anchor_b: [f64; 3]

Anchor point on body_b in local coordinates.

target_distance: f64

Target distance (for Distance constraints).

axis: [f64; 3]

Hinge axis in world space (for Hinge constraints).

stiffness: f64

Constraint stiffness (0..1, 1 = rigid).

enabled: bool

Whether the constraint is currently active.

Implementations

impl PyConstraint

pub fn distance( handle: u32, body_a: u32, body_b: u32, anchor_a: [f64; 3], anchor_b: [f64; 3], distance: f64, ) -> Self

Create a distance constraint between two bodies.

pub fn point_to_point( handle: u32, body_a: u32, body_b: u32, pivot: [f64; 3], ) -> Self

Create a point-to-point constraint (ball-socket joint).

pub fn hinge( handle: u32, body_a: u32, body_b: u32, pivot: [f64; 3], axis: [f64; 3], ) -> Self

Create a hinge constraint around axis at pivot.

pub fn with_stiffness(self, s: f64) -> Self

Set constraint stiffness (builder pattern).

pub fn set_enabled(&mut self, enabled: bool)

Enable or disable the constraint.
