How. I thought someone told me I could use OBSE's RunScriptLine function, but I looked at it in the docs and it doesn't seem right.

RunScriptLine works just fine with quest scripts because you can set the value of XXXXQuest.Variable to your own variable.
I don't see how you could get an object script value unless it's a global, or it is also a quest script var, or you use RunScriptLine in the object script itself to set your quest.var.

Like this:

if (JauffreRef.MQ04Voice == 1)

or

set Statue to (MartinRef.playerStatue)

or

set JauffreRef.MQ04Voice to 1

or

set AlvalUvaniRef.DrinkTimer to (AlvalUvaniRef.DrinkTimer + getSecondsPassed)


Like that. The object does need to be placed in the world and be persistent, however.
