sc_prefabs_v1.spawn

Catalogue snapshot — development preview

SDK 2.3.0 · game pack 0.6.0 · source e616ed69d8f9f77b0f4827881c86d91e4a7d1689 Published release: sdk-v2.3.0 (immutable approved assets; this development preview is not an approved release). Source-backed inventory is not a runtime or in-game verification claim.

Canonical ObjectContainers content-relative .socpak path (511 bytes max), finite zone-local pose and normalized quaternion. Caller-owned final entity ID, zero on failure; success means spawn initiation only. Shared 1024 owned quota and 128 own entities maximum, checked before mutation. Pending prefab ownership is never pruned by alive=0. Capability game.entities.prefabs is enabled by default for R1 by owner approval; Windows/SEH/streamed cleanup NOT VERIFIED.

Limitations / unestablished guarantees

• Windows engine/SEH/gameplay and streamed cleanup not verified.
• Owner-approved R1 default enabled; portable provider policy is synthetic evidence only, not Windows/SEH/gameplay acceptance.
• No packaged content or filesystem/online path access.

Parameters and buffers

sco_result (*spawn)(sco_plugin* self, const char* content_path, uint64_t zone_id, const double pos[3], const double rot_xyzw[4], uint64_t* out_id);
Canonical ObjectContainers content-relative .socpak path (511 bytes max), finite zone-local pose and normalized quaternion. Caller-owned final entity ID, zero on failure; success means spawn initiation only. Shared 1024 owned quota and 128 own entities maximum, checked before mutation. Pending prefab ownership is never pruned by alive=0. Capability game.entities.prefabs is enabled by default for R1 by owner approval; Windows/SEH/streamed cleanup NOT VERIFIED.

Results and failures

BAD_ARG invalid handle/path/pose/output; WRONG_THREAD; TOO_MANY quota; NOT_FOUND zone/content/class; UNAVAILABLE disabled capability or cleanup; FAILED provider refusal/fault. Output ID zero on failure.

Absent capability

Absent service: query_service NOT_FOUND; present disabled operation: UNAVAILABLE.

Ownership

Live caller owns result through existing game.entities ledger. Inputs copied for synchronous provider call, host-session table borrowed; no cross-boundary allocation.

Thread affinity

Game thread only; WRONG_THREAD otherwise.

Callback context

No plugin callbacks. Host-only provider callbacks synchronous, bounded and nonthrowing.

Reentrancy

No recursive reentry; host adapter must not call plugins.

Cleanup and cancellation

Use existing entities despawn/set_transform and game.owned retention/removal. Ordinary owner unload removes pending/streamed owned prefab via delayed removal primitive; no materialization/removal completion promise. Known ID on provider failure remains tracked for cleanup. Fault-retained native provider follows restart-required lifetime contract.

Language mappings

Status labels are copied verbatim from the catalogue: direct is native access; typed-wrapper is wrapper-backed; restricted is a subset/adaptation; unsupported means no supported route is established. No status implies universal safety.

ABI pins prove layout, not semantic behavior or a live game session.
