Smart Typewriter

The Smart Typewriter is a reusable object class that can be used to create a typewriter effect in your game. It can be used to display text in a cinematic way, with a typing sound and a delay between each character.

The built-in dialogue box uses the Smart Typewriter to display text. The Smart Typewriter can be customized to fit your game's style and needs.

Reusable Function

You can apply the Smart Typewriter to any text widget in Unreal Engine using the Play Typewriter Effect utility function.

Timer delays

The Smart Typewriter accepts custom pauses while printing a text line. You can set a numeric delay inside double parenthesis ((delay)).

- Leonidas
  This...((0.1)) is...((0.1)) Sparta!

By default the typewriter will interpret the delay as seconds. You can change the unit by adding it after the number:

- Bob
  Wow!((100ms)) I can't believe you are here, err...((1s)) Alice.

The supported units are:

Substring delays

The Smart Typewriter can also pause between substrings. You can set a delay after a substring using a map.

TObjectPtr<ASmartTypewriter> Typewriter = ...

Typewriter->AddSubstringsDelays({
    { "...", 2 },
    { ".",   1 }
});
