Generic Set/Get Variable (Flowgraph Node)

Overview

• Node Name: Generic Set/Get Variable
• Category: repeat_instant
• File: extensions/flowgraph/nodes/types/genericValue.lua

A dual-purpose node that either gets or sets a named flowgraph variable. Can operate on project-level (global) or graph-level variables.

Properties

Behavior

• init() - Defaults to getter mode with global scope. Sets up get pins.
• work() - Constructs the variable name from varName + optional suffix. In getter mode, calls self.target:get(varName). In setter mode, calls self.target:change(varName, value).
• setupGetPins() - Removes any existing val pins, creates an out pin named val.
• setupSetPins() - Removes any existing val pins, creates an in pin named val.

Serialization

• _onSerialize(res) - Saves getter and global flags.
• _onDeserialized(nodeData) - Restores flags and sets up appropriate pins.

How It Works

1. Set varName to the variable you want to access.
2. Toggle getter in properties to switch between read/write mode.
3. Toggle global to choose between project-level and graph-level scope.
4. Optionally use suffix for dynamic variable names (e.g. "score" + 1 → "score1").

-- Getter mode:
-- varName = "playerScore", suffix = nil
-- Reads from project variables: self.mgr.variables:get("playerScore")
-- Output: val = current value

-- Setter mode:
-- varName = "playerScore", val = 100
-- Writes to project variables: self.mgr.variables:change("playerScore", 100)

Key Dependencies

• self.mgr.variables - Project-level variable storage
• self.mgr.graph.variables - Graph-level variable storage

Additional Methods
