[LE] New to modding Skyrim, can't compile someone else's script - compiler error?

[AdmiralAlbia]

Background: Having never done it before, I decided to try and get my feet wet with Papyrus by fixing some minor annoyances in cpuLL's Myopia mod. Specifically, I wanted to cause the glasses to return to the inventory when dropped instead of falling on the floor and usually disappearing from the game forever - so the only change I needed to make was to comment out a single line of code and recompile. (I'd like to play around with adding things to its formlist too, but one problem at a time...)

 

Here's the script, which is obviously cpuLL's work and not mine:

Scriptname myopiaPlayerAlias extends ReferenceAlias

FormList property MyopiaGlassesList Auto

FormList property MyopiaForceSpellsList Auto

ImageSpaceModifier property myopiaImageSpace Auto

; This function set up the quest, it is done (and re-checked) when the mod is initialized for the first time and when the game reloads

; The quest associated as just a few stages and objectives

; Stage 0, just init, say that the vision is blurry, for a minute don't do anything and let enjoy this strange new experience

; Stage 1, Add the objective "Get the glasses", and add visible markers to the three pairs of glasses available, when the actor gets atleastone pair of glasses we go to the next stage

; Stage 2, you just have to wear the glasses, and the objective will tell you that. Once you wear them for the first time the objective and the quest are completed (but you will get blurry vision every time you are NOT wearing the glasses)

function doQuestInit()

doneQuest=1

; A couple of glasses is inside the Bee and Barb in Riften, another pair is in the kitchen of BanneredMare in Whiterun, another is in the WhinkingSkeever

; Wait a minute or two (randomly) and then force start the quest, start also altering the vision

myopia.start() ; This starts the quest

myopiaImageSpace.apply() ; This applyes the blurry and doubled vision

I have already fixed the compiler's folder locations and extracted my Scripts.zip (hence why we're down to three errors), but I can't seem to get the compiler to recognise these fuctions. Tried changing GetModByName to IsPluginInstalled, as I couldn't find the former on the Creation Kit wiki (and, again, this is my first ever Papyrus scripting attempt), but that throws the same error.

 

As I'm so new to this, I'm genuinely not sure if the problem is the code or the compiler, but I'm leaning towards the compiler. Having already extracted all my source scripts, though... how can I fix it?

[IsharaMeradin]

GetModByName is a SKSE function. It therefore requires that SKSE be installed and the source scripts (PSC files) from SKSE be installed to the Data/Scripts/Source folder.

[AdmiralAlbia]

Mm, I suspected it might be... thing is, SKSE is installed and its sources are unpacked. And as I said, I changed the lines to IsPluginInstalled (a native function), and got the same 'not a function or does not exist' error. Also, I have to assume that getName is native?

[IsharaMeradin]

GetName is also SKSE

 

Double check and make sure that you placed the SKSE PSC files in the same location as those from the scripts.rar file. Also, if you extracted the scripts.rar file after having installed SKSE, it will have overwritten the SKSE PSC files. Should that be the case, re-install them.

 

To know if you have the correct files in place:

Locate Form.psc and look for the function GetName

Locate Game.psc and look for the function GetModName

If they are not on those scripts, you do not have the correct files in place.

[AdmiralAlbia]

Ahh, thank you! I think I had it installed to the wrong directory. All compiling now :)

IsharaMeradin you is a genius. this just helped me, MO2 makes it tricky
