Writing scripts in Papyrus? There's one particular difference to scripting for previous games that's even giving a lot of experienced scripters some trouble.

In the old scripting language, it was possible to use some base form or reference in a script just by using its editorID. However, if you try to do that in a Papyrus script you'll find that it won't compile. What you need to use instead is a property.

The most common way to define a property looks like this (using the type "ObjectReference" as an example):

ObjectReference property MyRef auto

Once you've defined a property like this, you then need to associate it with a value. In order to do this, navigate to the object with your script attached in the Creation Kit, right click on your script, and select "Edit Properties".

In this window, you can assign values to all of the properties in your script. You'll want to click on your property, and then click on the "Edit Value" button on the right hand side of the window. After you do this, a drop-down menu will appear in which you can select one of any form of the same type as the property you declared. In this example, the list will be filled with references.

As an added bonus, if the name of your property is the same as the editorID of the form that you want it to represent, then the "Auto-Fill" button will select that form automatically. If you have a lot of properties like this, there's also an "Auto-Fill All" button at the bottom of the window.

Once you've done this, you'll be able to use your property as though it were the form you've associated with it.
