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 '''''-5''''' and then '''''+2'''''). Due to the limit of the number of choices available, there can only be one other option. For most, this option should be <u>'''''Return to Previous Menu'''''</u>. Here's an example: ('''''NumNewIngsDefault''''' is the variable that the player is setting. Also, due to wiki limitations, the messagebox has several line breaks even though these wouldn't be in the CS script) | Though not a necessary part of every menu, this is a nice bit of code.

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, as such: | If you want to use minimums and/or maximums for the variable, you'll need to run checks at a few key locations.
