Track Prefab (Flowgraph Node)

Overview

• Node Name: Track Prefab
• Category: once_instant
• File: extensions/flowgraph/nodes/scene/trackPrefab.lua

Allows the flowgraph to track a prefab that was spawned outside of the flowgraph system. Provides options to control cleanup behavior when the flowgraph stops.

Pin Schema

Input Pins

Behavior

• workOnce() - Registers the prefab with the flowgraph's prefab module via mgr.modules.prefab:addPrefab(), passing cleanup options.

How It Works

1. Fires once when triggered.
2. Adds the externally-spawned prefab to the flowgraph's prefab tracking system.
3. The cleanup options (dontDelete, skipNavgraphReload, skipCollisionReload) control what happens when the flowgraph execution ends:
   • By default, all three are true, meaning the prefab is preserved and no expensive reloads occur.
   • Set dontDelete to false to have the flowgraph clean up the prefab on stop.

Key Dependencies

• self.mgr.modules.prefab:addPrefab(id, options) - registers a prefab for flowgraph lifecycle management

Additional Methods

C:_executionStopped()

Called when graph execution stops. Used for cleanup.
