Struct DebrisImpact 

pub struct DebrisImpact {
    pub island: Island,
    pub grid: GridId,
    pub pos: DVec3,
    pub speed: f64,
    pub voxel_world_size: f64,
}

One landed island, drained via DebrisSystem::drain_impacts: everything the shatter needs.

Fields

island: Island

The island’s voxels + colours (grid-local, as detected) — the shatter burst samples these, not the sprite model.

grid: GridId

The grid the island was extracted from.

pos: DVec3

World position of the island’s pivot (bbox centre) at rest — flush on the surface it hit.

speed: f64

Impact speed in world units/second (≤ the terminal clamp).

voxel_world_size: f64

The source grid’s world units per voxel at extraction time — kept here so Self::burst_sites stays self-contained even if the grid is gone by shatter time.

Implementations

impl DebrisImpact

pub fn burst_sites(&self) -> Vec<([f32; 3], Rgb)>

DT.3 — the world-space burst sites for the shatter: every island voxel’s centre, translated to where the body landed (its grid-local offset from the bbox centre, scaled by the source grid’s voxel size, applied around Self::pos; the cosmetic yaw is ignored, matching the axis-aligned collision box). Feed straight into ParticleSystem::voxel_debris with from = pos for the colour-true shatter.

Trait Implementations

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

Formats the value using the given formatter.
