Menu Management Commands
By Chris Cromer

 

Creating your program, you can offer the player a choice using a system of menus. These may be short one-line questions (menu header) with several answers (menu elements), or a prompt to change some of the system parameters, for example, object movement speed. Let us consider these commands.

 

set.menu(n);

Message n is used as the header of the menu elements which follow.

set.menu.item(n, c);

Message n is used as a menu element, where c is this element's code (a number between 0 and 255).

submit.menu();

Ends menu creation.

enable.item(c); disable.item(c);

Enables or disables a menu item with the code c.

               |-------- heading
               v
           -------------------------------
           | File                        |
           -------------------------------
Menu   -- >| Save       |
Element    |------------|
           | Restore    |
           |------------|
           |XXXXXXXXXXXX| < - menu element disabled
           |------------|   using disable.item
           | Quit       |
           --------------

menu.input();

If Flag(14) = 1, a menu system is shown on the screen, allowing the user to choose an item. Whether an item with the code c has been chosen can be tested using a command 'controller (c)', where c is the code assigned to the menu item.
