Editing Scripting Tutorial Using Functions (section)

====Local Functions====
You can declare functions locally. That means that these functions live inside of one particular script, and can only be run if you have a specific script to run the function in. 
<syntaxhighlight lang="Papyrus">
 ;inside some script...
 float value = 3.0
 
 Function ModifyValue(float valueModifier)
    value = (value + 2.0) * valueModifier
 EndFunction
 
 Event OnActivate(ObjectReference actionRef)
    ModifyValue(5.0)
 EndEvent
</syntaxhighlight>
There are a few things going on here:
*'''Function''' - this is called to start a function declaration
*'''ModifyValue''' - this is the name of the function that you're making
*'''float valueModifier''' - here you are declaring a parameter. In this case, it means that you can pass a float in as a parameter for the function. Inside the function, you can use the variable "valueModifier" and that will be whatever number that gets passed into the function.
*'''value = (value + 2.0) * valueModifier''' - this is some logic inside the function. You could put any logic in here that you want. As you see, I'm using "valueModifier" like it's a variable. We don't know what the value of this variable is, however, as anything could be passed in.
*'''EndFunction''' - This ends the function declaration.
With a local function, you would have to actually have a scripted object in the world in order to use the function. This particular script has a variable called "value" in it, and if you're inside the script you can call ModifyValue() to change "value" to a different number. A different script can also call ModifyValue() on this script as well, and it would actually change the number stored in "value". A different script could use this script's function. <BR><BR>In this example, "value" would get set to 25.0 when you activate the scripted object for the first time.
