| ===Multiple Menus in a Spell Script===
| |
| 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.
| |
|
| |
|
| 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.
| |
|
| |
| Note also that, as of now, this hasn't been tested for multiple menus.

| '''Notes:'''
| |
| * Using multiple menus, or catching a button press with [[GetButtonPressed]] in a magic effect script requires that the spell duration be more than 0 in order for '''GetButtonPressed''' to capture the button.
| |
| * The [[ScriptEffectFinish]] block will always run immediately after the last running of the [[ScriptEffectUpdate]] block. Due to this, if the '''ScriptEffectUpdate''' block has a '''Return''' statement that fires at this point of the script, the '''ScriptEffectFinish''' block will not run.
| |
| * Spell using the script must have a '''Range''' of ''Self''
| |
| * ''Spell'' in the above script (TargetRef.Cast ''Spell'' TargetRef) must be replaced with '''Editor ID''' of the Spell using the script
