# Built-in effects list Here’s a list of all built-in effects ready to use in your games. (To add effects in your texts, visit here [add-effects-to-your-texts](https://docs.febucci.com/text-animator-godot/effects/add-effects-to-your-texts "mention")). You can also create your own effects: [create-your-own-effects](https://docs.febucci.com/text-animator-godot/effects/create-your-own-effects "mention"). ## Behaviors 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](https://docs.febucci.com/text-animator-godot/effects/add-effects-to-your-texts/modifiers "mention").

* `Tag`: represents the effect tag, unique in its category (eg. \) ## Appearances {% hint style="warning" %} **Disappearances** are not currently supported, but we are working on porting them. {% endhint %} Appearance Effects animate letters only when they’re appearing on screen. 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 Effects in the TextAnimator node, without having to write Appearance Effects tags in each text.* [#set-default-effects-to-the-entire-text](https://docs.febucci.com/text-animator-godot/add-effects-to-your-texts#set-default-effects-to-the-entire-text "mention") {% endhint %}

If you're interested in a looping fade, you can easily create your own in [Broken link](https://docs.febucci.com/text-animator-godot/effects/broken-reference "mention") (or let us know if you need any help! <3)
