LinkMessage Numbers | QuickySitter™ documentation

Edit me

QuickySitter uses link-message numbers in the range 90000 – 90500, identical to stock AVsitter 2. Stock numbers are unchanged from a sender’s perspective: a stock plugin’s link-message traffic works as-is in QuickySitter furniture. (Script-name probes are another matter: see Compatibility Matrix.)

This page lists the fork-specific numbers QuickySitter adds (in stock-unused ranges) and notes the stock numbers whose handler script moved or whose semantics changed slightly. For the complete stock AVsitter 2 reference, see avsitter2_link_message_reference.md in the QS repo (vendored copy of upstream).

Stock numbers used unchanged

90000-90014, 90030 (SWAP), 90033, 90045 (pose-played broadcast), 90050/90051 (menu pose pick), 90055/90056 (anim info), 90057 (helper move), 90060/90065/90070 (sit/unsit/permissions), 90075/90076 (oldschool helper), 90100/90101 (menu choice), 90150-90211, 90220 (play pose without opening the menu; [QS]prop handles it alongside 90200), 90230, 90298-90300, 90401-90500. From a sender’s perspective the contracts match stock.

Stock numbers whose handler script moved

Num	Stock home	QuickySitter home	Why
`90020`	sent to scripts asking for `[DUMP]`	sent from `[QS]boot` instead of adjuster	`[DUMP]` ownership moved to boot
`90021`	handled by `[AV]adjuster`	handled by `[QS]boot`	same: boot owns the cascade
`90022`	handled by `[AV]adjuster`	handled by `[QS]boot`	same: boot owns the receiver

Plugins still send 90022/90021 to LINK_THIS exactly like in stock; the listener just lives in a different script in the same prim.

Stock numbers with subtler semantic changes

Num Change

90301 sitB’s handler is stricter: it only refreshes the seated avatar when the saved pose is the one currently playing, compared by pose name (not by index) with a payload-shape check, and forwards pos/rot directly from the 90301 payload instead of re-reading LSD. Sender contract (name\|pos\|rot\|) unchanged. Stock plugins don’t send 90301 (it was sitA→sitB internal), so this is invisible externally.

Num	Change
`90301`	sitB’s handler is stricter: it only refreshes the seated avatar when the saved pose is the one currently playing, compared by pose name (not by index) with a payload-shape check, and forwards pos/rot directly from the 90301 payload instead of re-reading LSD. Sender contract (`name\\|pos\\|rot\\|`) unchanged. Stock plugins don’t send 90301 (it was sitA→sitB internal), so this is invisible externally.

Stock numbers no longer routed

Num	Status
`90302` (“sitA sends initial notecard settings to sitB”)	Removed. sitB reads `qs:cfg:<ch>` from LSD directly in `state_entry`. Incoming 90302 is silently ignored.
`90020` → sitB	sitB is no longer a `[DUMP]` source (boot owns the dump). Incoming 90020 to sitB is silently ignored.

Fork-specific numbers

All in stock-unused ranges. A stock-AVsitter plugin sending or receiving in these ranges would have collided with something, but the stock reference shows these slots as unused.

Boot self-check + reload (9002x)

Num	Direction	Use
`90023`	`[QS]boot` → all	`QS_BOOT_RELOAD`. Emitted at the end of the seed cascade. `[QS]sitB` reloads its page state from LSD on receipt (the retired MENU_LIST is gone), and `[QS]sitA` reloads too, eliminating the manual-reset step after a notecard re-save.
`90024`	`[QS]boot` → all	`QS_BOOT_WIPE`. Broadcast before boot wipes the seeded LSD and resets, when a notecard re-save invalidates the seeded state. sitA/sitB flip their booted flag back to FALSE so pre-boot guards re-engage until `QS_BOOT_RELOAD` (90023) fires.

See Boot Sequence.

Boot self-check probe (9007x)

Num	Direction	Use
`90077`	`[QS]boot` → `[QS]sitB`	Boot self-check probe (“is the menu pipeline present?”). One-shot from boot’s `state_entry`.
`90078`	`[QS]sitB` → `[QS]boot`	Boot self-check reply.

Plugin presence (9007x – 9009x)

Plugin presence is not a link-message handshake. Each plugin writes a qs:alive:<name> LSD flag in its state_entry (the offset plugin uses the inverted name qs:offset:alive); menu builders read those flags on demand, never caching. The only presence-related link-message is the census re-stamp:

Num	Direction	Use
`90079`	`[QS]boot` → all	`QS_ALIVE_CENSUS`. boot wipes every `qs:alive:*` flag and broadcasts this; surviving plugins re-stamp their flag in response, so a removed plugin drops out without an inventory probe.
`90093`	bidirectional	hudproxy presence probe (the live HUD-presence HELLO; `QSDUMP_HELLO` 90095 and `QS_SITB_HELLO` 90078 are also live, for the dump cascade and the boot self-check respectively). See HUD Integration.
`90094`	`[QS]boot` → all plugins	QSDUMP probe: “if you’re DUMP-capable, announce yourself now.”
`90095`	DUMP plugin → `[QS]boot`	QSDUMP hello: “I respond to 90020 DUMP messages.”
`90096`	plugin → `[QS]sitA`	QSALIVE count/version/caps probe (not a presence handshake). See QSALIVE Discovery.
`90097`	`[QS]sitA` (slot 0) → plugin	QSALIVE count/version/caps reply, plus one unsolicited boot-announce.

DUMP cascade ownership (9009x)

Num	Direction	Use
`90098`	`[QS]adjuster` → `[QS]boot`	“Start dump for channel.” Replaces stock adjuster-owned `[DUMP]`. `id` is a mode marker: `"quiet"` for the ADJUSTMODE live-view dump (URL only, chat banners suppressed), `""` (or `"loud"`) for the operator-visible `[DUMP]`. The boot self-check (90077/90078) never dumps.
`90099`	`[QS]boot` → self	Dump tick: self-trigger between dump-line iterations.

Quiet swap (9003x)

Num	Direction	Use
`90031`	menu source → `[QS]sitA`	Quiet SWAP, like stock `90030` SWAP but suppresses the swap announcement. Fork addition; stock furniture has no 90031 sender.

Plug-and-play plugin registry (9021x)

Num	Direction	Use
`90204`	`[QS]adjuster` → `[QS]root-security`	`QSADJ_ACL_SET`: apply an Adjust-ACL level from the `/5 adjust` chat command, `msg = "OWNER"` / `"GROUP"` / `"ALL"`. A stock-free slot inside the otherwise stock `90200` band. The adjuster sends it and writes `qs:sec:adjust` itself, both unconditionally, so the plugin’s RAM state cannot go stale and revert the level on the next census. Since 1.26.
`90212`	plugin → `[QS]sitB`	QSPLUG_REGISTER: `msg = "<label>\\|<click_chan>\\|<scriptName>"`. Registers a runtime button into the `[OPTIONS]` top-level menu. sitB dedupes by `scriptName`. Click dispatch lands on `<click_chan>` with `msg = <label>`, `id = <controller-key>`. See Options Menu Plugins.
`90213`	plugin → `[QS]sitB`	QSADJ_REGISTER: `msg = "<label>\\|<click_chan>\\|<scriptName>\\|<flags>"`. Like QSPLUG_REGISTER but the button lands in the `[ADJUST]` submenu instead of `[OPTIONS]`. `flags` bit 0 = owner-only (rendered per the Adjust ACL, like `[HELPER HUD]`). RAM registry, re-announced by the plugin on QSALIVE_REPLY (90097) so it survives a re-seed.

Personal pose offsets (9026x)

Num	Direction	Use
`90214`	`[QS]adjuster` → `[QS]faces`	`QSFACE_PICK`: open the facial-anim picker for a sitter slot. `msg = "<slot>\\|<controller>\\|<sitterAv>"`. Prim-local (sent `LINK_THIS`, and the receiver refuses a cross-prim sender), because the slot indexes the receiving prim’s own sitter list. Since 1.26.
`90215`	`[QS]adjuster` → creator-only plugins	`QS_FINALIZE`: broadcast by `/5 cleanup` just before the adjuster removes itself. Subscribers tear THEMSELVES down; the adjuster knows no plugin inventory names. Unheard when no such plugin is present. Since 1.26.
`90216`	plugin → `[QS]sitB`	`QSADJ_UNREGISTER`: drop a button registered via 90213. `msg = <scriptName>`, the same identity 90213 dedupes on. A plugin that deletes itself MUST send this first, otherwise its button outlives it and dispatches to a channel nobody listens on. Since 1.26.
`90238`	`[QS]sitB` → hudadmin	Click channel of the self-registered `💠 POSE HUD` entry (attach mode `menuplus`). Same handler as the 90510 button, so it toggles. Since 1.26.
`90260`	`[QS]offset` → `[QS]sitA` + hudproxy	“Mirror this RAM-tier personal offset.” ZERO/ZERO is the delete sentinel.
`90261`	`[QS]sitA` + hudproxy → `[QS]offset`	“Push every RAM-tier cached offset for this (sitter, slot) pair to me.”
`90262`	`[QS]sitA`, hudproxy, hudadmin, `[QS]debug` → `[QS]offset`	“Save this offset for (sitter, slot, pose).” Magic name `M#T!` is the all-poses fallback.
`90263`	`[QS]adjuster` → `[QS]sitA` + `[QS]offset`	“Drop stale customs after `[HELPER] [SAVE]`.”
`90264`	hudadmin → `[QS]offset`	“Wipe ALL personal offsets.” (hudproxy has no 90264 sender.)
`90265`	`[QS]offset` → all `[QS]sitA`	“Clear your RAM-tier mirror.” Paired with 90264.
`90266`	`[QS]adjuster` + hudadmin → hudproxy	“Flip QuickyHUD ADJUSTMODE remotely”: `"On"` / `"Off"`.

See Personal Pose Offsets.

Retired presence HELLOs (9008x – 9009x)

These per-plugin HELLO broadcasts were the original (pre-0.9951) presence mechanism. They were retired in 0.9951 and replaced by the qs:alive:* LSD flags + QS_ALIVE_CENSUS (90079) described above. The numbers are reserved and not reused; current scripts neither send nor listen for them.

Num	Was	Replaced by
`90088`	`QS_OFFSET_HELLO`: offset presence	`qs:offset:alive` LSD flag (inverted name).
`90089`	`QS_PROP_HELLO`: prop presence (gated `[PROP]`)	`qs:alive:prop` LSD flag.
`90090`	`QS_FACES_HELLO`: faces presence (gated `[FACES]`/`[FACE]`)	`qs:alive:faces` LSD flag.
`90091`	`QS_ADJUSTER_HELLO`: adjuster presence (gated `[HELPER]`)	`qs:alive:adjuster` LSD flag.
`90092`	`QS_SELECT_HELLO`: select presence (gated select routing)	`qs:alive:select` LSD flag (sitB also keeps an `[AV]select` inventory fallback for stock-AVsitter compat).

Re-Sync and dynamic props (9027x – 9028x)

Num	Direction	Use
`90271`	any in-prim source → `[QS]sitA`	SYNC-pose Re-Sync trigger. See Re-Sync Protocol.
`90280`	any in-prim source → `[QS]prop`	`QSPROP_ATTACH`: dynamic prop register + rez without notecard entry. See HUD Integration.

QuickyHUD-internal numbers (9027x)

These live entirely inside the QuickyHUD scripts (hudproxy ↔ hudadmin, both on the furniture prim). Listed here for range completeness; a stock plugin never sees them.

Num	Direction	Use
`90272`	hudproxy → hudadmin	`SELECT_OPEN_DIALOG`: render the SELECT (swap-target) picker.
`90273`	hudadmin → hudproxy	`SELECT_PICKED`: the chosen target token.
`90274`	hudproxy → hudadmin	`ATTACH_FOR_ADJUST`: ensure the operator has a HUD attached when ADJUSTMODE goes On.
`90275`	any source → hudproxy	`QSANIM_OCCUPANT`: animesh dummy occupant hook. See Animesh Adjust Dummies.
`90276`	hudproxy → linkset	`ADJUSTMODE_CHANGED`: the mode flipped, `msg = "On"` / `"Off"`. Fired from the single choke point every flip passes through. hudadmin uses the `"Off"` edge to retire HUDs that only existed for ADJUSTMODE. Nobody listens on stock AVsitter, so the broadcast is compat-neutral there. Since 1.26.

Compatibility summary

Stock plugin in QuickySitter furniture: ✅ link-message traffic works unchanged; plugins relying on [AV]sitA script-name probes degrade. See Compatibility Matrix.
QuickySitter scripts in stock-AVsitter furniture: ❌ doesn’t work, because sitA/sitB expect qs:cfg/qs:sitter/qs:p:* LSD keys that boot writes during seed; stock furniture has no [QS]boot. This is intentional, not a goal of the fork.
