==Syntax==
<syntaxhighlight lang="lua">
guiFadeElement ( element guiElement, bool state[, int speed, int decrease/increase] )
</syntaxhighlight>

===Required Arguments===
* '''guiElement''': the GUI element.
* '''state''': the new visibility state (true/false).

===Optional Arguments===
{{OptionalArg}}
* '''speed''': speed to decrease or increase the guiElement's alpha (from 50 to unlimited).
* '''decrease/increase''': decrease/increase's amount (from 1 to 255).
