Struct PinConstraint 

pub struct PinConstraint {
    pub anchor: Vec3,
    pub stiffness: f32,
    pub dead_zone: f32,
}

Pins a point to a fixed world-space position.

The correction snaps the constrained point back toward its anchor each step.

Fields

anchor: Vec3

stiffness: f32

How strongly to pull (0 = no correction, 1 = snap to anchor immediately).

dead_zone: f32

Max allowed deviation before pin activates (0 = always active).

Implementations

impl PinConstraint

pub fn new(anchor: Vec3) -> Self

pub fn soft(anchor: Vec3, stiffness: f32) -> Self

pub fn with_dead_zone(self, zone: f32) -> Self

pub fn solve(&self, pos: Vec3) -> Vec3

Compute position correction to apply to the constrained point.

pub fn move_anchor(&mut self, new_anchor: Vec3)
