| Like other variables, reference variables must be declared before they can be used:
| | #Redirect [[Ref Variable]] |
| | |
| <pre>
| |
| ref refVarName
| |
| </pre>
| |
| | |
| You can use a reference variable 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 reference variable 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 == player
| |
| </pre>
| |
| | |
| Or not another reference:
| |
| <pre>
| |
| if myReferenceVariable != player
| |
| </pre>
