Keep Prefab (Flowgraph Node)

Overview

• Node Name: Keep Prefab
• Category: once_instant
• File: extensions/flowgraph/nodes/scene/keepPrefab.lua

Marks a prefab to be kept after the flowgraph stops. By default, prefabs spawned during runtime are removed at the end.

Pin Schema

Input Pins

Behavior

• workOnce() - If id is provided, calls self.mgr.modules.prefab:setKeepPrefab(id, keep) to flag the prefab.
  • Passes flow through regardless.

How It Works

1. The node fires once when triggered.
2. Looks up the prefab by its ID in the flowgraph manager's prefab module.
3. Sets the "keep" flag so the prefab persists after the flowgraph execution ends.

Example Usage

-- In a flowgraph, connect this node after a Spawn Prefab node:
-- [Spawn Prefab] --> id --> [Keep Prefab]
-- Set keep = true to preserve the prefab after the graph stops

Key Dependencies

• self.mgr.modules.prefab:setKeepPrefab() - flags a prefab to persist beyond flowgraph execution

Additional Methods

C:init()

Initializes the node, setting up pins and default properties.
