}

A single field source (metaball) contributing to the entity’s scalar field.

Fields

position: Vec3

Current world-space position of this source.

rest_offset: Vec3

Base (rest) position, relative to entity center.

strength: f32

Current field strength (modulated by HP, damage, breathing).

radius: f32

Influence radius. Beyond this distance, contribution is zero (for Wyvill/Linear/SmoothPoly).

falloff: FalloffType

How the field decays with distance.

color: Vec4

Color contribution for surface coloring.

emission: f32

Emission intensity.

base_strength: f32

Strength at full HP (before any modulation).

breath_amplitude: f32

Breathing animation amplitude.

breath_phase_offset: f32

Breathing animation phase offset (different sources breathe slightly out of sync).

destroyed: bool

If true, this source has been permanently destroyed by a crit.

damage_reduction: f32

Temporary strength reduction from recent damage (decays over time).

last_hit_time: f32

Time of last damage hit to this source.

tag: String

Name/tag for this source (e.g. “head”, “torso_upper”, “left_arm”).
