One of my spells has a script attached, and from inside this script I want sometimes to apply an stagger effect to the target.

I know I can create a self stagger effect, then create another spell which calls this effect, and pass this spell through a property to script, finally using the Cast() function.

But I just want to know: Is there any simpler way to do this without using a second spell?

Since there doesn't seem to be a stagger function (I could be wrong), the only way to apply stagger would be through a spell. And since you don't want the stagger to happen immediately, 100% of the time, then I think it'll always require at least two spells. Or at least a perk and a spell.

During the OnEffectStart event, but only if certain conditions come true. Those conditions have some calulations, so I can't replicate them outside the script.

Then why not just add the conditions in? Are you not able to use any of the http://www.creationkit.com/Category:Condition_Functions?

Just make this scripted affect like:

Event OnEffectStart(Actor akTarget, Actor akCaster)bool conditionsweretrue = false   if myconditionsaretrue      SendAnimationEvent(akTarget ,"bleedoutstart")	  conditionsweretrue = true   endifEndEventEvent OnEffectFinish(Actor akTarget, Actor akCaster)   if conditionsweretrue     SendAnimationEvent(akTarget,"bleedoutstop")   endifEndEvent

That does a bleedout....but you could substitute staggers eventname.

Yes, that's it. Thanks a lot.
