Struct ark_api::world::CollisionMatrix

pub struct CollisionMatrix { /* private fields */ }

A collision matrix, specifying what can collide with what.

Due to its triangular shape, for fast access it’s simply replicated twice in the array, mirrored across the diagonal.

Create one, then use Environment::set_collision_matrix to apply it to all future created physics objects. Does not change existing objects!

Implementations

impl CollisionMatrix

pub fn new_full() -> Self

Creates a new collision matrix where all layers can collide with all other layers.

pub fn new_empty() -> Self

Creates a collision matrix where no layers can collide against any other layer.

pub fn set(&mut self, a: usize, b: usize, can_layers_collide: bool)

Specifies whether layer a should collide with layer b.

Note - this is equivalent to saying that layer b should collide with layer a, you don’t need to specify that separately, it’s always symmetric.

pub fn get(&self, a: usize, b: usize) -> bool

Checks whether this matrix lets layers a and b collide.

Trait Implementations

impl Clone for CollisionMatrix

fn clone(&self) -> CollisionMatrix

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<CollisionMatrix> for CollisionMatrix

fn eq(&self, other: &CollisionMatrix) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
