Internals

How It Works

1. init() - Sets self.string = "Hello World" and multiLine = false.
2. work() - Outputs self.string to the output pin.
3. drawCustomProperties() - Renders a checkbox to toggle multi-line mode. Shows either InputText or InputTextMultiline for editing.
4. drawMiddle() - Shows up to 10 characters of the string inline, with ... for longer strings.

Serialization

• Serializes newlines as \\n escape sequences.
• On deserialization, restores newlines and reads from either nodeData.data.value (legacy) or nodeData.string.

Example Usage

-- This node outputs a constant string every frame.
-- Set in the node properties panel.
-- Equivalent to:
self.pinOut.value.value = "Hello World"

Additional Methods
