FMjEntityRecord¶

Cached non-articulation entity metadata: a UMjBody whose owner is

not an AMjArticulation (props, free-jointed scene objects, ...). Built once at session start (PostCompile) and consumed by UURLabZmqPublishTransport for "scene//state" PUB topics and by the step server for the entities block in step replies. Articulations have their own typed cache; this struct is for everything else dynamic in the world.

Public Properties¶

Property	Type	Description
`MjId`	`int32`	UMjBody MjID after compile.
`Name`	`FString`	Compiled name (the same string mj_id2name returns).
`bHasFreeBase`	`bool`	True if the body owns a single mjJNT_FREE joint (qpos[7]/qvel[6]).
`BodyComp`	TWeakObjectPtr<UMjBody>	Weak ref kept for diagnostics; consumers should index by MjId.
