How to detect disease contraction?

[VencGanence]

Is it possible to detect when the PC contracts a disease? I don't need to know which disease it is, simply the moment they contract it. I don't want to detect that they have a disease, but that they gained a disease.

Nevermind.

Note the function is deprecated. The page explains further.

 

So to get the time the PC contracts a disease, I'd wager you'd want to combine IsSpellTarget to detect if the PC has a disease, if yes then GetCurrentTime, then go from there? I dunno. Just spitballin.

Seems like the best way to do it is as described on the linked article from Fiore1300. Loop through the players spells, probably every second or so, and if any of them is a disease, the script can switch a variable that will kick off whatever you want to do.

That does seem like the only way to me, but it has the unwanted drawback of being unable to detect multiple diseases unless I go a step further tracking sources of effects in addition to effect types. That just sounds like it'd get a bit too complicated, which worries me that it may impact performance.

 

There are the OnMagicApply and OnMagicCast event handlers, but my testing of OnMagicApply fired inconsistently, plus I don't know if a disease would trigger the handler despite technically being a spell.

Maybe OBSE has the functions you need?

There's functions to get the total magnitude of disease effects, but that information doesn't tell me what I want.

I found a method to detect disease contraction, using an OnMagicApply event handler:

;Parameters
;-----------------------------------------------------------------------------
ref MagicItem
ref Caster
ref Self
short Type
;-----------------------------------------------------------------------------

;-----------------------------------------------------------------------------
begin Function { MagicItem, Caster }
;-----------------------------------------------------------------------------

	;GetSelf returns who was hit
	Let Self := GetSelf
	Let Type := GetSpellType MagicItem

	if ( Self == Player && Type == 1 )

		DebugPrint "%n contracted %n." Self MagicItem

	endif


;-----------------------------------------------------------------------------
end
;-----------------------------------------------------------------------------

Unfortunately, this handler type cannot be filtered by target, so there will be some wasted cycles.

 

Edit: oddly enough, the Caster for diseases is the victim, so I can apply a filter for Caster. The question is if mod added diseases have the same behaviour.

Well, you're in luck. I don't think any mods add new diseases.
