sc_relocation_v1_1.request_position

Catalogue snapshot — development preview

SDK 2.4.0 · game pack 0.8.0 · source d16f013c629797275e40124184b261da54cce0ef Published release: sdk-v2.4.0-rc.1 (release candidate 1, attested assets; the final signed release follows; this development preview is not an approved release). Source-backed inventory is not a runtime or in-game verification claim.

Admit a copied 48-byte position-only request with finite bounded coordinates, timeout 1..60000ms, a nonzero target ID and current spatial observation epoch. Requires an explicit verified position backend and fresh offline/player/session/known-equal-system authority. No quaternion or FullPose fallback; output ticket unchanged on refusal.

Limitations / unestablished guarantees

• No grounded native position transport, target-instance producer or readback adapter is installed. Synthetic source/provider evidence only; not run in game.
• Native C and raw C++ only; C#/Lua mutation bindings are unsupported. Published RC1 does not contain this extension.

Header source

Parameters and buffers

sco_result (*request_position)(sco_plugin* self, const sc_relocation_position_request* request, uint64_t* out_ticket);
Admit a copied 48-byte position-only request with finite bounded coordinates, timeout 1..60000ms, a nonzero target ID and current spatial observation epoch. Requires an explicit verified position backend and fresh offline/player/session/known-equal-system authority. No quaternion or FullPose fallback; output ticket unchanged on refusal.

Results and failures

SCO_OK admitted, not arrived; SCO_BAD_ARG invalid request/live owner; SCO_UNAVAILABLE stale epoch, absent position backend or unknown/unsafe authority; SCO_TOO_MANY one global pending request or ticket exhaustion; wrong thread returns SCO_WRONG_THREAD. Outputs unchanged on refusal.

Absent capability

game.relocation.position is OFF with the existing native/legacy backend. A valid request returns SCO_UNAVAILABLE; old hosts lack service 1.1.

Ownership

Local player only; owner-scoped opaque tickets. No arbitrary entity/pointer/owner writes. Copied request and caller-owned output. 32 retained terminal tickets; oldest terminal evicted at admission.

Thread affinity

Game thread only; wrong thread returns SCO_WRONG_THREAD without touching state.

Callback context

No callbacks; bounded tick-driven work.

Reentrancy

Non-reentrant.

Cleanup and cancellation

Shares one pending and 32 terminal owner-scoped tickets with FullPose. Completion requires a later fresh finite position in the admitted target frame within 0.05m, without rotation reads. Independent target-instance change fails TARGET; spatial epoch is checked only at admission. Owner/session/system/safety/fault guards, no retry/rollback and cancel/status lifetimes remain.

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.
