Struct ChainDef 

pub struct ChainDef {
    pub user_data: u64,
    pub points: Vec<Vec2>,
    pub materials: Vec<SurfaceMaterial>,
    pub filter: Filter,
    pub is_loop: bool,
    pub enable_sensor_events: bool,
    pub internal_value: i32,
}

Used to create a chain of line segments. Must be initialized using default_chain_def. (b2ChainDef)

The C struct uses points/count and materials/materialCount pointer + length pairs; the Rust port carries owned Vecs whose lengths encode the counts (the C notes these are cloned).

Fields

user_data: u64

Application specific shape data.

points: Vec<Vec2>

An array of at least 4 points.

materials: Vec<SurfaceMaterial>

Surface materials. Must have length 1 (one material for all segments) or points.len() (a unique material per segment).

filter: Filter

Contact filtering data.

is_loop: bool

Indicates a closed chain formed by connecting the first and last points.

enable_sensor_events: bool

Enable sensors to detect this chain. False by default.

internal_value: i32

Used internally to detect a valid definition. DO NOT SET.
