Editing Ref Variable

In the GECK, a ref variable may store either a [[reference]] <b>or</b> a [[Base Form|base form]]

Like other variables, reference variables must be declared before they can be used: 

<pre>
ref   refVarName  
</pre>

==Stored References==

You can use a ref variable that stores a reference anywhere you could use an [[Reference|object reference]]. Uninitialized reference variables hold a value of 0, and will cause a script to silently stop running if used to call a [[Reference_functions|reference function]]; otherwise a ref variable storing a reference acts just like any other reference. 

You set reference variables using the set command, like other variables. Normally, you will want to use a [[:Category:Reference_Variable_Functions|reference variable function]], which returns a [[formID]]. For example:
 
<pre>
set myRef to GetContainer  
</pre>
  
Like other variables, you can set a reference variable on another scripted object: 

<pre>
 set BobRef.myRef to GetSelf   
</pre>

To check if a ref variable is unset:
<pre>
if myReferenceVariable == 0
</pre>

To check if a ref variable is set:
<pre>
if myReferenceVariable
</pre>

To check if a ref variable is another reference (in this example the player):
<pre>
if myReferenceVariable == PlayerREF
</pre>

Or not another reference:
<pre>
if myReferenceVariable != PlayerREF
</pre>

==Stored Base Forms==

You may store a base form in the same way:
<pre>
ref MyWeapon
set MyWeapon to Weap10mmPistol
</pre>

Beware that this is still a base form and may not be used as the [[calling reference]] to functions that allows this syntax, although it may be passed as the target if the function permits this.
