# Built-in effects list

Here’s a list of all built-in effects ready to use in your games.

{% hint style="info" %}
You can also create your own effects:

* [Create effects in the Editor](/text-animator-unreal/customization/create-your-own-effects/create-effects-in-the-editor.md)
* [Writing Custom Effects (C++)](/text-animator-unreal/customization/create-your-own-effects/writing-custom-effects-c++.md)
  {% endhint %}

## Behaviors <a href="#behaviors" id="behaviors"></a>

Behavior Effects animate letters continuously during time, after the letter has been shown.

You can also use Modifiers, which let you change the characteristics of your Behavior effects individually [Modifiers](/text-animator-unreal/effects/add-effects-to-your-texts/modifiers.md).

* `Tag`: represents the effect tag, unique in its category (eg. \<shake>)
* `Different with size`: true if the effect results differently based on different sizes and fonts.

## Appearances and Disappearances <a href="#appearances-and-disappearances" id="appearances-and-disappearances"></a>

Appearance Effects animate letters only when they’re appearing on screen, while Disappearance Effects make them dynamically disappear. For this reason, they’re mostly used in combination with the typewriter, which shows/hides letters one after another.

{% hint style="info" %}
Reminder: you can set default Appearance and Disappearance Effects in the Animated Text Block details among the "Default Tags" section, without having to write Appearance Effects tags in each text. [Add effects to your texts](/text-animator-unreal/effects/add-effects-to-your-texts.md#set-default-effects-to-the-entire-text)

{% hint style="info" %}
Reminder: by default, appearances start with `{` while disappearances include an hashtag `{#` (to simply indicate that they're **the same appearances effects in reverse**). You can change brackets and everything in your settings Data Asset, in case you'd like to use other symbols.

[^1]: PSA the fade effect is the only effect that *doesn't* loop, but keeps the letters hidden forever! If you're interested in a looping fade, you can easily create your own in [Create effects in the Editor](/text-animator-unreal/customization/create-your-own-effects/create-effects-in-the-editor.md) (or let us know if you need any help! <3)
