Spawn Logger

Spawn Logger is a passive LabFusion moderation utility for BONELAB. It records which player requested each mod-item spawn and exposes the newest 30 events in BoneMenu, both as a combined feed and as per-player histories.

Detection model

• Attribution is snapshotted when Fusion receives the server-approved spawn response, before asset downloading or asynchronous instantiation can delay completion.
• The snapshot stores the player's platform ID and display name immediately. Reuse of a disconnected player's small session ID cannot reassign an outstanding spawn.
• Fusion's server-allocated entity ID correlates the response with the finished object and suppresses duplicate callbacks.
• Scene-source spawns and the short level-load synchronization window are ignored.
• The finished object is checked for a Magazine component. Crate title and barcode metadata provide a fallback for unusual or disabled hierarchies.
• SLZ content is excluded by default using the SLZ. namespace, internal-pallet metadata, and pallet author metadata (SLZ, Stress Level Zero, or StressLevelZero). A persistent Log SLZ Content toggle can include it when explicitly enabled.
• Magazines remain excluded regardless of the SLZ setting.
• Responses delivered directly by a non-host transport and entity-ID collisions are written as warnings to the MelonLoader log. Transport identity and claimed ownership are recorded separately so a forged payload does not automatically frame its target.

The logger deliberately reports an unresolved player as Unknown (ID n) instead of guessing from proximity or current object ownership. Those signals can change after the spawn and are not proof of who initiated it.

Usage

Open BoneMenu and select Spawn Logger:

• All Spawns shows the merged feed.
• Players contains one page per player.
• Clear All Logs clears this client's history.
• Auto-Clear On Leave controls whether departing players are removed.
• Log SLZ Content includes SLZ/internal-pallet spawns when enabled; it is off by default.
• Debug Counters shows how many spawns were received, logged or dropped, and why. The same totals are written to the MelonLoader log at each level load.

Repeated spawns of the same item by one player within 4 seconds are shown as one entry with a count. A spawn whose crate is not installed is logged by barcode as (not installed).

Every accepted event is also written to the MelonLoader log. The mod never despawns, blocks, or punishes anything.

Requirements

• MelonLoader
• BoneLib 3.2.1 or later
• LabFusion 1.14.2 or later
