The first thing we need to do is create the activator object. This object will be used to cast spells.

In the [[Object_Window|Object Window]], Expand the WorldObjects item and select Activator. Right-click in the object list to the right and select "New" from the context menu that pops up.
In the [[Object_Window|Object Window]], Expand the WorldObjects item and select Activator. Rename the activator with the Editor ID "ActivatorFlameNode0" to "SourceID" by slowly double-clicking on it, changing the name, and selecting "Yes" when the menu comes up.


Set these fields:
We also need to create a reference of the new activator. In the [[Cell View Window]], select "Interior" from the pull-down menu. Then select the Editor ID "TestQuest01" in the box on the left. Right-click it and select "Duplicate Cell". Rename the cell to something you'll remember and double-click it to open it in the [[Render Window]]. Now, drag your new [[Activator]] "SourceID" to the [[Render Window]]. Double-click on the activator to open the "Reference" window. Name it "Source" in the "Reference Editor ID" box. Mark it as a "Persistent Reference" and "Initially Disabled".
*<b>ID:</b> Set this to "ActivatorSource"
*<b>NIF:</b> Set this to "magiceffects\null.nif" (This makes the activator invisible)
 
Leave the rest of the fields alone and click "OK".

===The Self Spell Script===
This script uses [[PlaceAtMe]] to create an activator and then uses that activator to [[Cast]] the AOE spell.
This script uses [[MoveTo]] to move your activator to the caster and then uses that activator to [[Cast]] the AOE spell.

This script will be run on every actor that is hit by the TutCallLightningAoeSpell. This script will then create an activator using PlaceAtMe and use it to cast a lightning bolt at the affected actor. (Remember: This happens for each actor hit!)

Instead of using the lines
<pre> 
        set source to me.PlaceAtMe ActivatorSource, 1, 0, 0
        float height
set height to me.GetPos z
set height to height + 1000
source.SetPos z, height
</pre>
an alternative is to place an example of the activator on the map,give it a unique name (eg 'source' in this case) and check the persistent reference box- This creates a single copy  of ActivatorSource in the game instead of creating new ones every time the spell is used with the placeatme command.Then replace these lines with
<pre>
        source.moveto me,0,0,1000
</pre>
