Though not a necessary part of every menu, this is a nice bit of code. This allows the player to use a menu to set a variable to any number (I suppose it's limited by the short/long variable limits). Basically, the player is given the current number the variable is set to, and is allowed to change it from '''''-2''''' to '''''+2'''''. If they want to change it by more than that, they can modify it by '''''-10''''', '''''-5''''', '''''+5''''', or '''''+10''''' and then the menu is displayed again, with the new number. This allows the player to select any number (i.e., if they want -3, they would choose
<pre> elseif (Choosing == -22)
messagebox "Set the default number of essences to be created.
return
endif</pre>
If you want to use minimums and/or maximums for the variable, you'll need to run checks at a few key locations. To cover all of the '''''-10''''', '''''-5''''', '''''+5''''', '''''+10''''' options place the check right before the [[MessageBox]] function. You have 2 options for the other, variable-changing options ('''''-2''''', '''''-1''''', '''''+1''''', '''''+2'''''):
*Place the check(s) inside each of those '''''Choice''''' sections
*Place the check(s) in a menu that all of them run through. In this case, all of these '''''Choice'''''s run through '''''Choosing == -21''''', so all of the checks(s) can be placed immediately before the [[MessageBox]] function of that menu, as such:
<pre> elseif (Choosing == -21)
if (NumNewIngsDefault < 0)
set NumNewIngsDefault to 0
endif
messagebox "Creation Options:"
"Set default number of ingredients"
...</pre>
