Struct RopeChain 

pub struct RopeChain {
    pub points: Vec<VerletPoint>,
    pub constraints: Vec<DistanceConstraint>,
    pub lifetime: f32,
    pub age: f32,
}

A chain of point masses connected by distance constraints, forming a rope.

Fields

points: Vec<VerletPoint>

constraints: Vec<DistanceConstraint>

lifetime: f32

Maximum simulation lifetime in seconds. 0 = infinite.

age: f32

Implementations

impl RopeChain

pub fn new(start: Vec3, end: Vec3, segments: usize) -> Self

Create a rope from start to end with segments links.

pub fn step(&mut self, dt: f32)

Step physics: gravity + Verlet integration + constraint solve.

pub fn attach_start(&mut self, pos: Vec3)

Fix the start point at a position.

pub fn attach_end(&mut self, pos: Vec3)

Fix the end point at a position.

pub fn apply_gravity(&mut self)

Apply standard gravity to all points.

pub fn sever_at(&mut self, segment_index: usize) -> Option<RopeChain>

Sever the rope at a segment index, returning a new RopeChain for the detached portion (from the cut point to the end). The current rope is truncated to end at the cut point.

pub fn get_points(&self) -> Vec<Vec3>

Get positions of all points.

pub fn is_expired(&self) -> bool

Check if this rope has expired.

pub fn current_length(&self) -> f32

Total length of the rope (sum of segment distances).

pub fn apply_force(&mut self, force: Vec3)

Apply a force to all points.

Trait Implementations

impl Clone for RopeChain

fn clone(&self) -> RopeChain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RopeChain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
