Struct PyIsland 

pub struct PyIsland {
    pub id: u32,
    pub bodies: Vec<u32>,
    pub constraints: Vec<u32>,
    pub sleep_state: IslandSleepState,
    pub quiet_frames: u32,
    pub sleep_threshold: f64,
    pub sleep_frames: u32,
}

An island groups bodies and constraints that can interact.

Fields

id: u32

Unique island id.

bodies: Vec<u32>

Handles of rigid bodies in this island.

constraints: Vec<u32>

Handles of constraints in this island.

sleep_state: IslandSleepState

Sleep state.

quiet_frames: u32

Frames below the velocity threshold (used for sleep triggering).

sleep_threshold: f64

Velocity threshold for sleeping (m/s and rad/s combined).

sleep_frames: u32

Number of frames needed to trigger sleep.
