Struct PhysicsBudget 

pub struct PhysicsBudget {
    pub fixed: u32,
    pub dynamic: u32,
    pub kinematic: u32,
    pub sensors: u32,
    pub joints: u32,
    pub anchors: u32,
    pub spawn_headroom: u32,
}

The reservation a world’s physics content implies.

Grouped by the kind of body the simulation builds rather than by the asset that asked for it, because that is what the simulation sizes its storage against.

Fields

fixed: u32

Immovable bodies: static colliders plus the world’s floor.

dynamic: u32

Freely simulated bodies.

kinematic: u32

Position-driven bodies: the player capsule and the character rigs.

sensors: u32

Sensor bodies, one per trigger volume.

joints: u32

Joints connecting two bodies.

anchors: u32

Hidden static bodies minted to anchor a world-anchored joint.

spawn_headroom: u32

Bodies held back for entities created after init.

Implementations

impl PhysicsBudget

pub const fn derive(counts: &PhysicsCounts, spawn_headroom: u32) -> Self

Derive the reservation for a world’s counts, holding back spawn_headroom bodies for entities created at runtime.

The floor body is always built, so fixed is one past the static collider count.

pub const fn body_total(&self) -> u32

Bodies the authored world builds at init.

pub const fn body_cap(&self) -> u32

The hard ceiling on live bodies: everything init builds, plus the headroom held back for runtime spawns. The simulation refuses to build a body past this.
