Component body grammars

AnvilData modelApplies toRR

Component headers do not store a universal body size. Each class requires its own grammar; where that grammar is unknown, header recognition can retain bytes without establishing their fields. All lengths here exclude the 13-byte component header. Observed

Type / id Body rule Checked scope Confidence
Visual EC658D29 Object, polymorphic instance data, variable tail Geometry and UI profiles Observed
RigidBodyComponent C177D702 Usually 847 / 855 bytes; activity-zone array can extend it 4,318 initial bodies; later NPC exception Observed

A measured fixed length is not an on-disk length field. The single-count MaterialOverrider and Breakable profiles do not discriminate all possible arrangements of their repeated fields. Observed

Each 66-byte item is 00 + u64 + type, two u32, u8, two ValueWithRandom objects (u64 + type 0xF85FBB25 + two f32), then u32. The length reaches the next component or measured end on all 2,041 bodies. Observed

The unnamed component 0xE139F584 has 113 + 9k bytes on 1,990 of 2,014 checked bodies: EventListener, counted links, null handle and SoundInstance. The 24 COL_Relic_* exceptions contain nested event objects. Observed

What some opaque components hold

Section titled “What some opaque components hold”

Several component types without a length rule have been identified by their owners and registry classes, which tells what they contribute without a byte grammar. Observed · six-forge census

Component Bodies Content Confidence
BillboardComponent 1,148 Only on MAD_HUD_*_GROUP minimap Entities, beside WidgetGroup and Layout and never a Visual: HUD markers Observed
GrassVisual 46 The grass model library; see grass Observed
VisualTerrainComponent 2 On Terrain_TemplateMap, with PhysicsTerrain and PhysicsProps: terrain tuning values Observed
StaticDDecalComponent 2 A deferred decal; see terrain deferred decals Observed
Which fixed-length rules generalize beyond their samples?

One- and two-body measurements establish those bodies only. The opaque-component census and exceptions prevent treating every row as an exhaustive schema. Unknown
