__NOTOC__
{{Client function}}
This function checks whether the easing function exists (built-in easing functions and those who were created by addEasingFunction).
==Syntax==
<syntaxhighlight lang="lua">
bool easingFunctionExists ( string name )
</syntaxhighlight>

===Required Arguments===
*'''name:''' The name of easing function to be checked.

===Returns===
Returns a true if the easing function exists, ''false'' otherwise.

==Example==
<syntaxhighlight lang="lua">
DGS = exports.dgs

if not DGS:easingFunctionExists("test") then --Check whether easing function named "test" exists,if not, then create one.
DGS:addEasingFunction("test",[[
return math.abs(value^2-0.5)*2
]]) --Add easing function named as "test"
end

parent = DGS:dgsCreateWindow(200,100,400,400,"DGS Parent Window",false) --Create a window
DGS:dgsSetAlpha(parent,0)
DGS:dgsAlphaTo(parent,1,false,"test",2000) --set animation with easing function that we added.
