Hey guys, I just need a little help to get the ball rolling. I had this script back in Oblivion that made you deal more damage the more you got hurt. Here is that script, for reference:

Now, in Oblivion I was simply able to attach this to a quest script and let it run in the background. But in Skyrim, it appears that it needs to extend an object. So how do I get a script to attach to the player character and let it run in the background?

Similarly, is there a more efficient method of doing this? Or is what I got basically the best method for it? (As a small explanation, the script looks to see if the player gets hurt, then increases or decreases stats based off of the difference in health.)

From what I understand, quest script is still there. If you want your script to run every so often, you could create a Quest as you did in Oblivion.
In the Quest window you just created, click on the 'Scripts' button on the right most bar. There you will be able to assign script(s) to your quest.

Unlike in Oblivion, you can have multiple scripts running on 1 quest. (I'm yet to find how this works, but most likely those scripts are running on different Threads of that quest)

If you like to know more about 'extends' you can google on Object Oriented programming (OOP). There are quite a bit of topics on that, but on the wiki, the author did a great job of explaining OOP to a Layman
In short, a script quest could extend something like:

ScriptName YourScript extends Quest Conditional

In Oblivion, you could set the fQuestDelayTime to control how often the script being processed, in CK, you could do RegisterForUpdate() instead.

Hope it helps

Aha, that's exactly what I needed! Much thanks. I'll post again if I need more help with the specifics of the script, but I think I can work it out from here.

So, ran into some issues. Not sure what the errors compiling are giving me right now.

Scriptname SacriersBlood Extends Quest;Sacrier's Blood Script version .1int LastActorHealthint CurrentActorHealth == GetActorValue(Health)Function Sacrier()registerForUpdate(0.1)endFunctionEvent OnUpdateIf GetActorValue(Health) <= LastActorHealththen GetActorValue(Unarmed) == (CurrentActorHealth - LastActorHealth)Else GetActorValue(Health) >= LastActorHealththen GetActorValue(Unarmed) ==  (CurrentActorHealth - LastActorHealth)EndIfCurrentActorHealth == LastActorHealthLastActorHealth == GetActorValue(Health)EndEvent

Am I even looking at the right actor for this to work? I only want it to work on the player character, specifically a certain custom race. Anyone got some pointers for me? The compile is spitting out a couple nonsense errors. I have my PC in japanese mode right now so this is jibberish, but I'll post it in case it helps:

The "==" operator is a comparison; you'll want to use the "=" operator, which is an assignment, when initialising your CurrentActorHealth variable. You'll also need to call http://www.creationkit.com/GetActorValue_-_Actor on something, and you might not actually want to initialise it here.

As well as that, your "Scarier" function is never called, and since the script only has an http://www.creationkit.com/OnUpdate_-_Form event, unless it's registered for update somewhere else nothing will ever run. You'll probably want to add a http://www.creationkit.com/OnInit event to start things up.

Ok, I thought I had the syntax correct to look at the player actor here, but it's giving me a bunch of errors. Here's the current version of the code:

Scriptname SacriersBlood Extends Quest;Sacrier's Blood Script version .1Actor Function GetPlayer() native globalint LastActorHealthint CurrentActorHealth = Game.GetPlayer().GetAV(Health)Event OnInit()registerForUpdate(0.1)gotoState ("Sacrier")endEventState SacrierEvent OnUpdate()  If Player.GetAV(Health) <= LastActorHealth   then Game.GetPlayer().GetAV(UnarmedDamage) = (CurrentActorHealth - LastActorHealth)  Else Player.GetAV (Health) >= LastActorHealth   then Game.GetPlayer().GetAV(UnarmedDamage) =  (CurrentActorHealth - LastActorHealth)  EndIf  CurrentActorHealth = LastActorHealth  LastActorHealth = Game.GetPlayer().GetAV(Health)EndEventendState

And Here are the Errors:

What am I doing wrong here? I just can't seem to sort it out.

Bump (These forums are moving pretty fast)

Another Bump, still not sure how I need to do this.

Get rid of the "then" thing you have in there. You don't need it, and I expect the compiler doesn't like it.

Cipscis

Okay, I think I made a lot of progress now. I only get one error now. Here's the current script:

Scriptname SacriersBlood Extends Quest;Sacrier's Blood Script version .1Actor Function GetPlayer() native globalActor Function GetReference()Actor Player = Player_Alias.GetReference(Game.GetPlayer)int UnarmedDamageint Healthint LastActorHealthint CurrentActorHealthEvent OnInit()registerForUpdate(0.1)gotoState ("Sacrier")endEventState SacrierEvent OnUpdate()  If Player.GetAV(Health) <= LastActorHealth   Game.GetPlayer().ModAV(UnarmedDamage, (CurrentActorHealth - LastActorHealth))  Elseif Player().GetAV(Health) >= LastActorHealth   Game.GetPlayer().ModAV(UnarmedDamage, (CurrentActorHealth - LastActorHealth))  EndIf  CurrentActorHealth = LastActorHealth  LastActorHealth = Game.GetPlayer().GetAV(Health)EndEventendState

And the error is: c:\program files (x86)\steam\steamapps\common\skyrim\Data\Scripts\Source\temp\SacriersBlood.psc(15,0): mismatched input 'Event' expecting ENDFUNCTION

Any ideas?

Duh, I forgot to end the two functions at the beginning. I did some tweaking:

Scriptname SacriersBlood Extends Quest;Sacrier's Blood Script version .1Actor Function GetPlayer() native globalPlayer_Alias=Actor Function GetReference()Actor Player = Player_Alias.GetReference(Game.GetPlayer)endFunctionint UnarmedDamageint Healthint LastActorHealthint CurrentActorHealthEvent OnInit()registerForUpdate(0.1)gotoState ("Sacrier")endEventState SacrierEvent OnUpdate()  If Player.GetAV(Health) <= LastActorHealth   Game.GetPlayer().ModAV(UnarmedDamage, (CurrentActorHealth - LastActorHealth))  Elseif Player().GetAV(Health) >= LastActorHealth   Game.GetPlayer().ModAV(UnarmedDamage, (CurrentActorHealth - LastActorHealth))  EndIf  CurrentActorHealth = LastActorHealth  LastActorHealth = Game.GetPlayer().GetAV(Health)EndEventendState

Which gave me these errors:

Somewhere I'm messing up my variables but I don't know how. Can someone shed some light on this for me?

Sorry for the bumps, just trying to get this ready to roll out.

Get rid of the trailing assignment operator (=) on line 4, to start with. Also, you don't need to declare GetPlayer() in your script - all native functions like this one have already been declared in the right scripts. Because your variable "Player" is declared within a function, it will only be accessible within that function.

See where that gets you. There might still be a few errors left over.

Cipscis

Thanks for all your help Cipscis. I think I'm almost there. Here's what I've got now:

Scriptname SacriersBlood Extends Quest;Sacrier's Blood Script version .1Alias Player_Aliasint UnarmedDamage = 0int Health = 0int LastActorHealth = 0int CurrentActorHealth = 0int Boost = 0Actor Function GetReference()Actor Player = Player_Alias.GetReference(Game.GetPlayer())endFunctionEvent OnInit()registerForUpdate(0.1)gotoState ("Sacrier")endEventState SacrierEvent OnUpdate()  CurrentActorHealth - LastActorHealth = Boost  If Player.GetAV(Health) != LastActorHealth   Game.GetPlayer().ModAV(UnarmedDamage, Boost)  EndIf  CurrentActorHealth = LastActorHealth  LastActorHealth = Game.GetPlayer().GetAV(Health)EndEventendState

The only error I'm getting right now is:
c:\program files (x86)\steam\steamapps\common\skyrim\Data\Scripts\Source\temp\SacriersBlood.psc(25,23): no viable alternative at input 'LastActorHealth'

I have no idea what that means... Not sure what the issue is now.

That's probably due to this line:

CurrentActorHealth - LastActorHealth = Boost

In assignment operations, the left hand side must always have only a single term, which is the variable or property that is going to have its value assigned. Try changing that line to this:

Boost = CurrentActorHealth - LastActorHealth

Not sure why it suddenly thinks there isn't a getreference, or that player isn't defined... Isn't that what I'm defining in the GetReference function? Also, what does it mean none is not a user defined type/cannot compare a none to a int? Am I declaring my variables incorrectly?

GetReference isn't defined for that context. You've defined it so that it can be called on the type ScariersBlood, but it doesn't exist for Alias. It exists for http://www.creationkit.com/GetReference_-_ReferenceAlias, though, have you tried that type?

Cipscis

Like this?

No, you're still declaring Player_Alias as type Alias. Try either declaring it as type ReferenceAlias or casting it to that type whatn you call GetReference on it. I'm not sure which is the more appropriate way to do it.

Cipscis

This is quite the doozy... Okay, what can I do to alleviate these errors? I'm not sure what's the cause of them.

Uhmm, I would love to help you, but I think you should read the wiki carefully, to understand the flow of the script

This line:

ObjectReference Player = Player_Alias.GetReference()

cannot be reached because it doesn't tie to any trigger or event. Since you are running a Quest script, you must make sure when and where such calls are triggered.
One way to solve it is to put that line into the Event OnInit()

Hope it helps,

I don't think that's it. The initialisation bit will work there, and it's valid outside of any event or other function because it's declarative code.

The problem here, I think, is that Player_Alias can't have a value at that point. Declare it as a property instead of a variable, and assign it a value with the Creation Kit.

Cipscis

xD My bad, I think I really need to sleep, brain stop functioning properly xD......
What I meant was, the initialization is fine outside of the trigger block (if you set it to some actual value), but the xxx.GetReference() is not, since this is a function call

It's part of the initialisation, though. The declaration of that variable acts as an entry point for the expression in the initialisation, so it's still valid where it is an will run at the appropriate time.

The compiler error is referencing a later line, too, which implies that there isn't a problem with the initialisation.

Cipscis

Since you replied to my thread I've been kind of watching this thread progress. I'm trying to accomplish something similar after all, so I've been trying to fix my own errors per suggestions made here.

This is what I ended up with in the end for my health check. (I'm stripping the unnecessary code just to show the parts pertaining to yours.)

Function OnUpdateGameTime()   	 Actor Player = Game.GetPlayer()        If Player.GetAV("Health") < 1       	 ;Do Stuff        EndifEndFunction

If I tried to instantiate player under the OnInit event block (or as anything other than an Actor), it would not run. Creating player as an actor property worked as well, but I only used it in this specific instance so I decided not to do that.
