4.6 Typewriting Function

Dialog Typewriting

Image	Info
	Initiates a typewriting effect on the specified text with customizable reveal modes and timing.
Description
The Dialog Typewriting Node is an asynchronous Blueprint action that processes a text string and reveals it over time. This node is specifically designed to work with the BDC Dialog System, handling rich text decorators and custom commands like <wait X> automatically. You can choose between different reveal modes, such as per-character (Glyph), per-word, or per-sentence. It also allows for fine-tuned control over the speed of the revelation, including extra pauses after punctuation marks to make the dialogue feel more natural. Being an asynchronous node, it provides an Update output that fires for every step of the reveal process, allowing you to update your UI in real-time. The Finished output triggers once the entire text has been revealed and the processed text is complete.

In- and Outputs

Name	Type	Description
InText		The full text to be processed and revealed. Supports rich text tags and Dialog Commands.
Mode		Define the granularity of the reveal: Glyph: Reveals character by character. Word: Reveals word by word. Sentence: Reveals sentence by sentence.
delayPerUpdate		The base delay (in seconds) between each reveal step. Default is 0.05s.
delayAfterFullstop		Additional delay (in seconds) added after punctuation marks like . ? ! ;.
delayFinished		Extra delay (in seconds) after the text is fully revealed before calling the Finished output.
Update		Execution pin triggered at each step of the reveal. It passes out the current progress and partial text.
Finished		Execution pin triggered when the typewriting effect is complete.

Delegate Outputs

Both Update and Finished outputs provide the following data pins:

Name	Type	Description
OutText		The text string containing all currently revealed characters and necessary closing tags.
CurrentGlyph		The index of the last revealed character (ignoring rich text tags).
GlyphsLeft		The number of characters remaining to be revealed.
GlyphsTotal		The total character count of the processed text.

The <wait X> command can be placed anywhere in the InText to introduce a pause of X seconds at that specific position during the typewriting process.
Example: "One moment... <wait 2.0> Okay, let's go!"

Punctuation detection for delayAfterFullstop automatically handles: . ? ! ;
