Does anyone know what the HasSpell function is?

I saw (somewhere) it written as:

[size=4]Game.GetPlayer().HasSpell(abhorse)[/size][size=4]

[/size]

But that turns up a 'missing RPAREN at '\\r\\n'...

All I basically want to do is run an (If Player.HasSpell X == 1 ) script.... :S

The creationkit wiki page is just empty...
http://www.creationkit.com/HasSpell

Thanks again for any input

I haven't looked at the scripting syntax of any of the Elder Scrolls games, but in regular programming languages calling a function of an object has a space for parameters ().

In other words, wouldn't calling the HasSpell function on player look like:
Player.HasSpell(spell goes here)
with the paranthesis?

It's here: http://www.creationkit.com/HasSpell_-_Actor.

Posting your entire script here as well as the compile errors you are getting would help in figuring out what exactly is wrong, but I’ll give it a shot with the information you provided.

The error you mention – “missing RPAREN at ‘\r\n’” basically means that the compiler expected a RPAREN – the “)” character – but instead found the end of a line. The example you posted above seems to be the correct syntax, so my guess is that when you typed it into your script, you forgot the right parenthesis at the end of the line. The compiler error should have a line number on it that will point you at the offending line

OK, that cleared up one issue, at least, thanks

This script is really rough, I am just trying to get my head around how things work now-- so please ignore that it does not seem to really 'do' anything properly; thanks for the help

That compiler error means that it doesn’t know what “DiseaseBoneBreakFever” is. Note that Papyrus has no knowledge of what is in the master file, so you’ll have to get the disease you want via a different method known as a http://www.creationkit.com/Differences_from_Previous_Scripting#Properties.

In short, you’ll want to add “Spell Property DiseaseBoneBreakFever Auto” to your script, probably near your existing GameHour property, just to keep things organized. That will tell the compiler what DiseaseBoneBreakFever is (a property with a type of Spell), and will let the compile error go away.

Then you’ll want to point the property at the appropriate disease in the editor via the property window on the script. (I am assuming the Disease is a Spell, you may have to change the type a little if the dropdown in the editor doesn’t display it. The type that the form you’re interested in appears under in the object window may give you a hint as to what Papyrus type is appropriate)

Thank-you very much. I will try that in a moment, but it seems to make sense to me

If the Script does not recognise what is in the Master, does that mean you could reference other Mods? So if I had A and B, I could reference Spells in A, just by defining them in B?

Edit:

That seems to work It saves

However, in game nothing happens... I do not think that second half of my script (from Event OnUpdate) is working at all... The first part does, and the message displays... so it is something there.. If anyone could point out that issue, I would be much obliged

Not entirely sure what you’re asking for, but in general, the compiler cannot see anything in the master file or any mods. The only thing it can see is what is in the script files, so you’ll need to make a property (which the compiler understands) and give that property a value in the editor (which is what ‘glues’ the game and script together).

What’s going wrong isn’t obvious from your script, but there are a few steps you could try to help narrow it down. First, turn on script logging (you want http://www.creationkit.com/INI_Settings_(Papyrus)#bEnableLogging, http://www.creationkit.com/INI_Settings_(Papyrus)#bEnableTrace, and http://www.creationkit.com/INI_Settings_(Papyrus)#bLoadDebugInformation, all set to 1), then sprinkle a few http://www.creationkit.com/Trace_-_Debug calls in various parts of your script, like at the beginning of the update event, inside your if statements, etc, that would help you keep track of what your script is doing. Then monitor the Papyrus.0.log file inside "My Documents/My Games/Skyrim/Logs" (may have to launch the game twice to get it to make the log the first time) for your trace statements to see what’s happening.

You can also try typing in “DumpPapyrusUpdates” (or “DPU”) into the console to spit out a list of everything registered for update events, and “DumpPapyrusStacks” (or “DPS”) into the console to dump a list of everything actually running to see if your script is stuck somewhere. The output for both of those functions goes to the script log. The log will also detail any errors your script may be causing, so keep an eye out

Example:

Event OnUpdate()Debug.Trace("Got an update! PCIsAVampire = " + PCIsAVampire)If ( PCIsAVampire == 1 )  If ( Game.GetPlayer().HasSpell(DiseaseBoneBreakFever) )  EndIf  PCCurrentBlood = ( PCCurrentBlood - 1 )  If ( PCCurrentBlood < 0 )   PCCurrentBlood = 0  ElseIf ( PCCurrentBlood > PCMaxBlood )   PCCurrentBlood = PCMaxBlood  EndIf    If ( GameHour.GetValue() >= 6 ) && ( GameHour.GetValue() < 20 )   Debug.Trace("Taking damage!")   Debug.MessageBox("TakingDamage")  else    Debug.Trace("Not taking damage!")  EndIf  EndIfRegisterForSingleUpdate(1)EndEvent

This is the error I am gettig now...

But I DO pass a Spell, I think:

Any idea what is up?

While you are correctly defining your property and passing the value of that property to the HasSpell function, the game is complaining because your property doesn’t actually have any value. You’ll want to make sure that you’ve given the property a value inside the editor wherever you’ve attached your script. (Pro tip: The property window can be resized and will show all your values you’ve given to properties in the list)

Thanks. That resolved it

I seem to have hit one last issue now, though... When I start the Mod, it correctly comes up that the disease has been added-- but it is not added. I commented out the 'Remove' line, in case that was breaking it somehow, but even with that gone, the Disease does not take effect on the player... Chaning it to an ability had the same effect.
If I try via the console, it comes up with a random percent, DOES NOT add, and then eventually will.

I have 'Disallow Absorb/Reflect' and 'Ignore Immunities' checked.

Ah – I bet I know what’s going on. “AddSpell” added the spell you gave it to the player’s spell book. It didn’t apply the disease as if you had been hit by it. RemoveSpell will then remove it from the spell book, but not dispel it. And HasSpell is checking the spell book, not what is applied to the player. I think what you actually want here is http://www.creationkit.com/Cast_-_Spell, http://www.creationkit.com/DispelSpell_-_Actor, and http://www.creationkit.com/HasMagicEffect_-_Actor used like this:

Actor player = Game.GetPlayer(); To apply the diseaseZCDMSotVVampireDisease.Cast(player, player); To remove the diseasePlayer.DispellSpell(ZXDMSotVVampireDisease); To see if the player has the diseaseif Player.HasMagicEffect()  ; Do cool stuff!endIf

SmKViper,

Thanks for the help, but I am still having a nightmare with this...
1. I tried that change, and nothing happened; but turning it back, suddenly it DID start happening, so I have no idea what happened there.

2. I finally managed to add the Spell, but hit on another issue-- it was not showing up. Remaking it fixed this-- somehow it had become locked as 'constant/contact' -- any way to change this after the spell has been initially made? It always seems to gray out, and removing the effects does not open it up for me... :S
