I am using the tutorial on quests on creationkit site and am in last chapter "loose ends". It says to add ObjectReference to script for stage 20... How do I go about doing this?

Please help... Really want to finish this Quest...

You want to add an ObjectReference property for your script. Please post up the whole code or give us more info. What tutorial?

Quest Design Fundamentals, last Chapter.

You didn't really mention where at specifically in the tutorial you are.

I'm assuming you're talking about the Map Marker section.

Navigate to your Quest > Quest Stages> Stage 20

At this point, you should have the following:
SetObjectiveCompleted(10)
SetObjectiveDisplayed(20)

Next to "Compile," you'll see "Properties." Click Properties > Add Property > Type "Object Reference" > Name "DungeonMarker"

Click Ok, highlight your new DungeonMarker property from the "Property Name" list. Click Edit Value > Pick Reference in Render Window. Select the dungeon marker.

Edit:
Also add DungeonMarker.AddToMap() in the Stage 20 Papyrus Fragment section.
Should look like:

SetObjectiveCompleted(10)
SetObjectiveDisplayed(20)
DungeonMarker.AddToMap()


Come back and let us know if that worked.
