sc_entities_v1.alive

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.

1 when the entity is streamed in, else 0 (also when the capability isn’t ready or off the game thread).

Limitations / unestablished guarantees

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

Header source

Parameters and buffers

int (*alive)(uint64_t entity_id);
1 when the entity is streamed in, else 0 (also when the capability isn’t ready or off the game thread).

Results and failures

Absent table: query_service NOT_FOUND; missing operation capability: UNAVAILABLE (alive: 0); invalid/released self: BAD_ARG. 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 entity/watch tracking; IDs are session values. Internal allocation unspecified.

Thread affinity

Game thread only (WRONG_THREAD elsewhere, alive returns 0); last_error any thread. Recursive reentrancy unspecified except unwatch in callback.

Callback context

unspecified

Reentrancy

unspecified

Cleanup and cancellation

No in-flight cancellation entrypoint; owned entities removed and watches ended on ordinary unload/non-retained crash cleanup, except kept entities. 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_entities.h (*alive)
cpp	typed-wrapper	include/scosdk/game/entities.hpp bool Alive(uint64_t id) const noexcept { return t_ && Covers(t_->size, offsetof(sc_entities_v1, alive)) && t_->alive && t_->alive(id) != 0; }
csharp	typed-wrapper	sdk/csharp/Sco.Sdk/Game/Entities.cs public bool Alive(ulong id) => Covers(8) && _t->alive != null && _t->alive(id) != 0;
