Struct PreFracturedCache 

pub struct PreFracturedCache {
    pub cache: HashMap<Entity, Vec<ProceduralChunk>>,
}

Stores pre-fractured chunks to avoid expensive runtime calculations (Pre-fracture Caching). Ideal for AAA games where destruction must not drop frames.

Fields

cache: HashMap<Entity, Vec<ProceduralChunk>>

Maps an Entity ID to its pre-calculated fracture data

Implementations

impl PreFracturedCache

pub fn new() -> PreFracturedCache

pub fn pre_fracture( &mut self, entity: Entity, extents: Vec3, num_pieces: u32, seed: u64, )

Pre-calculates fracture chunks for an entity and stores them in the cache. This should be called during a loading screen.

pub fn get_fracture_chunks( &self, entity: Entity, original_transform: &Transform, original_body: &RigidBody, original_velocity: &Velocity, impact_point: Vec3, impact_force: f32, ) -> Option<Vec<(RigidBody, Transform, Collider, Velocity, ProceduralChunk)>>

Spawns the chunks from the cache if available, taking only O(N) time to clone instead of O(N^3). If not in cache, optionally falls back to runtime calculation.

Trait Implementations

impl Default for PreFracturedCache

fn default() -> PreFracturedCache

Returns the “default value” for a type.
