<lowercasetitle>Quaternion</lowercasetitle>
__NOTOC__
Quaternion is used to define the rotation angle by GTA:SA game engine, which is different from MTASA which is based on Euler angle
This function returns the Euler angle(rotx,roty,rotz) from quaternion(rotx,roty,rotz,rotw).this is non-mtasa function, user need to put this function in your lua scripts.
==Syntax==
<syntaxhighlight lang="lua">

===Required Arguments===
* '''rotx,roty,rotz,rotw''': The quaternion from IPL file

===Returns===
* '''rotx,roty,rotz''': The Euler angle
