Load Project (Flowgraph Node)

Overview

• Node Name: Load Project
• Category: once_p_duration
• File: extensions/flowgraph/nodes/thread/loadProject.lua

Loads and starts a flowgraph project from a file path, enabling multi-project (threaded) flowgraph execution.

Pin Schema

Input Pins

Output Pins

Behavior

• init(mgr) - Initializes targetId to nil.
• postInit() - Configures the path pin to accept .flow.json files via file dialog.
• _executionStarted() / _executionStopped() - Resets targetId.
• workOnce() - Resolves the path (tries with and without .flow.json extension) and calls self.mgr.modules.thread:startProjectFromFilepath(fp, self). Outputs the project ID.

How It Works

1. Set the path to a flowgraph project file (e.g. "flowgraphEditor/myProject").
2. On execution, the node loads and starts the project as a child thread.
3. The output id can be used with sendMessage / receiveMessage nodes for inter-project communication.

-- The node resolves the path and starts the project:
local fp = self.mgr:getRelativeAbsolutePath({
  path,
  path .. ".flow.json"
})
local projectId = self.mgr.modules.thread:startProjectFromFilepath(fp, self)

Key Dependencies

• self.mgr.modules.thread - Thread module for managing child projects
• self.mgr:getRelativeAbsolutePath() - Path resolution utility
