Fields

user_data: u64

set_index: i32

index of solver set stored in World. May be NULL_INDEX.

local_index: i32

body sim and state index within set. May be NULL_INDEX.

head_contact_key: i32

[31 : contactId | 1 : edgeIndex]

contact_count: i32

head_shape_id: i32

shape_count: i32

head_chain_id: i32

head_joint_key: i32

[31 : jointId | 1 : edgeIndex]

joint_count: i32

island_id: i32

All enabled dynamic and kinematic bodies are in an island.

island_index: i32

Need this island index for faster union-find

mass: f32

inertia: f32

Rotational inertia about the center of mass.

sleep_threshold: f32

sleep_time: f32

body_move_index: i32

this is used to adjust the fellAsleep flag in the body move array

id: i32

flags: u32

body_flags bits

type_: BodyType

generation: u16

Monotonically advanced when a body is allocated in this slot. Used to check for invalid BodyId.

name: String

Body name for debugging (C: char[B2_NAME_LENGTH + 1]).

Trait Implementations

impl Clone for Body

fn clone(&self) -> Body

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Body

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

Formats the value using the given formatter.

impl Default for Body

fn default() -> Self

Returns the “default value” for a type.
