PAPYRUS SCRIPT: Code fails to compile

[Littledohboy15]

The code below is failing to compile but I honestly don't know why. I see the text in the output compiler but I'm not sure If I'm actually wrong or something is not referencing the right stuff to make me not wrong. 

Script TL:DR I makes it so theres a ap cost Mult for me to affect with spells, perks, etc.

It is a script made in a Magic Effect. I made the Global: ActionPointCostMult

Scriptname APCostInterceptorMagic extends activemagiceffect

GlobalVariable Property ActionPointCostMult Auto
Actor Property PlayerRef Auto Const

Float lastAP = -1.0
Float checkInterval = 0.25

Event OnEffectStart(Actor akTarget, Actor akCaster)
    if akTarget == PlayerRef
        lastAP = PlayerRef.GetActorValue("ActionPoints")
        RegisterForSingleUpdate(checkInterval)
    endif
EndEvent

Event OnUpdate()
    float currentAP = PlayerRef.GetActorValue("ActionPoints")
    float diff = lastAP - currentAP

    if diff > 0.1
        float mult = ActionPointCostMult.GetValue()
        float extraDrain = diff * (mult - 1.0)
        if extraDrain > 0
            PlayerRef.ModActorValue("ActionPoints", -extraDrain)
        endif
    endif

    lastAP = currentAP
    RegisterForSingleUpdate(checkInterval)
EndEvent

*Really funny that Nexus the king of Bethesda modding doesn't have a papyrus script highlighter

Here's the errors:

For Fallout 4 it's just GetValue() (and can be used on any Object Reference, not just Actors), same with ModActorValue() which is now ModValue()

RegisterForSingleUpdate() no longer exists, you can use StartTimer() to achieve the same (and instead of OnUpdate, use OnTimer)

I recommend this highlighter for VS code, it'll save you much headache :

So yes, my information is completely out of date. That helped me understand quiet a bit
Now it's just telling me something that's pretty obvious that could lead to a problem. Which is that "ActionPoints" is a string and not the actually in game name for that value. which was as simple as just removing the " "

But I also don't think this is the games Value for Action Points in general and so I have to find that now

The name doesn't matter, you have to add it as a property (or use GetFormFromFile).

Say, you add a property that is called "Butterbread" and points to the object that is the AP Actor Value, then you'd use SetValue(Butterbread). The name of the variable doesn't matter at all, only the object (the AV) it points to.
