===Multiple Menus in a Spell Script===
===Multiple Menus in a Spell Script===
Below is an example of multiple menus in a spell script. '''Step''' is used to control the stages of [[ScriptEffectUpdate]] for the '''MessageBox''' and the '''GetButtonPressed''' functions. While the initial '''MessageBox''' for the spell could have been in the [[ScriptEffectStart]], it is in the '''ScriptEffectUpdate''' block for clarity. Most of the button names as well as scripting have been left out so that the basics of manipulating multiple '''MessageBox''' functions can be seen.
A spell presents several challenges for multiple menus, but it can be done. Most importantly, you will need to set a high duration on the spell (see [[GetButtonPressed#GameMode or MenuMode?]]). However, the player could still open enough menus to run down the duration, no matter how long. To cover this scenario, all of the menu variables will be copied to a persistent object (in this case, the quest MenuVariables) when the spell runs out, and the spell will be recast.


<pre> ScriptName ExampleScript
This leads to one more small problem - if the variables are left set, then every time the spell is cast the menu would start more it left off before (well, ok, this could be cool, but I'll assume it's undesirable). To solve this, all of the external menu variables will be reset when the player exits the menu.
 
Short Step
Note also that, as of now, this hasn't been tested for multiple menus.
Short ButtonChoice1
 
Short ButtonChoice2
The quest script:
{Set Other Variables}
<pre>scn MenuVariablesScript
 
Short Choosing
Begin ScriptEffectStart
Short Choice</pre>
 
{Set up start of Spell}
The spell script:
Set Step to 1
<pre>Short Choosing
Short Choice
End
