sc_actors_v1.despawn

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.

Removes an NPC you spawned with spawn_npc. SCO_OK starts the removal: the NPC leaves the world within a few seconds (one that hasn’t streamed in yet goes once it has), and the id is no longer yours. SCO_NOT_FOUND: not an NPC you spawned here, or despawned already.

Limitations / unestablished guarantees

• Internal allocation unspecified.
• Recursive reentrancy unspecified.
• Additional failures/output state unspecified unless described in the buffer contract.
• Game-service behavior not verified in a game session.

Parameters and buffers

sco_result (*despawn)(sco_plugin* self, uint64_t entity_id);
Removes an NPC you spawned with spawn_npc. SCO_OK starts the removal: the NPC leaves the world within a few seconds (one that hasn’t streamed in yet goes once it has), and the id is no longer yours. SCO_NOT_FOUND: not an NPC you spawned here, or despawned already.

Results and failures

Absent table: query_service NOT_FOUND; missing operation capability: UNAVAILABLE; invalid/released self: BAD_ARG. See method detail for game failures. Additional failures/output state unspecified unless described in the buffer contract.

Absent capability

Absent table: query_service NOT_FOUND

Ownership

Caller buffers; no allocation crosses boundary. Host owns NPC tracking; entity IDs are session values. Internal allocation unspecified.

Thread affinity

Game thread only (WRONG_THREAD elsewhere); last_error any thread. Recursive reentrancy unspecified.

Callback context

unspecified

Reentrancy

unspecified

Cleanup and cancellation

No in-flight cancellation entrypoint; owned NPCs removed on ordinary unload/non-retained crash cleanup; despawn starts deferred removal. Retained-provider faults skip owner resource-release hooks and require restart; backing resources remain retained, not safe for cached calls.

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.

Language	Catalogue status	Source evidence / wrapper tokens
c	direct	include/sc_actors.h (*despawn)
cpp	typed-wrapper	include/scosdk/game/actors.hpp sco_result Despawn(uint64_t id) const noexcept { return t_ && Covers(t_->size, offsetof(sc_actors_v1, despawn)) && t_->despawn ? t_->despawn(self_, id) : SCO_UNAVAILABLE; }
csharp	typed-wrapper	sdk/csharp/Sco.Sdk/Game/Actors.cs public ScoResult Despawn(ulong id) => !Covers(24) || _t->despawn == null ? ScoResult.Unavailable : _t->despawn(Self, id);
lua	unsupported	sdk/docs/lua.md Lua gets the game services read-only: queries, never a function that changes the game, so a script owns no NPCs.

Examples

None identified in the catalogue; this is not proof none can exist.
