Struct GpuDensityEntityData 

#[repr(C)]
pub struct GpuDensityEntityData {
    pub position_scale: [f32; 4],
    pub color: [f32; 4],
    pub params: [f32; 4],
    pub params2: [f32; 4],
    pub bones: [GpuBone; 16],
}

Everything the GPU needs to draw one entity this frame.

Fields

position_scale: [f32; 4]

World position, and the scale from entity space to world units.

color: [f32; 4]

A tint over every bone’s colour. White leaves them alone.

params: [f32; 4]

(hp_ratio, breath_phase, breath_amplitude, density_falloff).

params2: [f32; 4]

(bone_count, particle_count, jitter, binding_strength).

bones: [GpuBone; 16]

Implementations

impl GpuDensityEntityData

pub fn bone_count(&self) -> usize

How many bones are live.

pub fn requested_particles(&self) -> u32

How many particles the entity asked to be drawn with.

pub fn particle_count(&self, budget: u32) -> u32

The particle count actually drawn, under a budget.

pub fn weights(&self) -> ([f32; 16], f32)

The bone weights, and their sum. Bones with no weight get none of the particles.
