sc_world_v1.raycast

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.

Casts a ray from from (metres, in zone zone_id’s local frame) along dir (any non-zero length; it is normalised) for at most max_dist metres, and fills *out_hit (out_hit->size must be sizeof(sc_world_hit)). max_dist must be positive and finite; one over SC_WORLD_RAY_MAX_DISTANCE is clamped to it. The cast tries the zone and then up to two of its parents (never the world’s root zone), as sc-offline’s build mode does, and reports the first hit, in the frame of zone_id. Nothing is skipped: your own player’s body can be hit. SCO_OK: hit. SCO_NOT_FOUND: nothing hit within max_dist (last_error says “no hit”), or the zone isn’t streamed in, or you haven’t spawned. SCO_BAD_ARG: a NULL pointer, zone 0, a non-finite or zero direction, a bad max_dist or a too-small out_hit->size. SCO_UNAVAILABLE: game.world.raycast isn’t ready. SCO_FAILED: the game faulted. *out_hit is zeroed (apart from size) on every failure. Implementation: NULL/undersized hit rejected before zeroing; adequately-sized hit is zeroed excluding size, only known fields written. Unknown caller tail untouched.

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 (*raycast)(uint64_t zone_id, const double from[3], const double dir[3], double max_dist, sc_world_hit* out_hit);
Casts a ray from from (metres, in zone zone_id’s local frame) along dir (any non-zero length; it is normalised) for at most max_dist metres, and fills *out_hit (out_hit->size must be sizeof(sc_world_hit)). max_dist must be positive and finite; one over SC_WORLD_RAY_MAX_DISTANCE is clamped to it. The cast tries the zone and then up to two of its parents (never the world’s root zone), as sc-offline’s build mode does, and reports the first hit, in the frame of zone_id. Nothing is skipped: your own player’s body can be hit. SCO_OK: hit. SCO_NOT_FOUND: nothing hit within max_dist (last_error says “no hit”), or the zone isn’t streamed in, or you haven’t spawned. SCO_BAD_ARG: a NULL pointer, zone 0, a non-finite or zero direction, a bad max_dist or a too-small out_hit->size. SCO_UNAVAILABLE: game.world.raycast isn’t ready. SCO_FAILED: the game faulted. *out_hit is zeroed (apart from size) on every failure. Implementation: NULL/undersized hit rejected before zeroing; adequately-sized hit is zeroed excluding size, only known fields written. Unknown caller tail untouched.

Results and failures

Absent table: query_service NOT_FOUND; missing operation capability: UNAVAILABLE; BAD_ARG for invalid required outputs. 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; queries do not own entities. 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 cancellation entrypoint; synchronous query.

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_world.h (*raycast)
cpp	typed-wrapper	include/scosdk/game/world.hpp return t_->raycast(zone, from, dir, maxDist, &hit);
csharp	typed-wrapper	sdk/csharp/Sco.Sdk/Game/World.cs r = _t->raycast(zoneId, f, d, maxDist, &h);
