A controller is an event that has occured due to the user selecting a menu item or pressing a key. There are 50 controllers available (numbered from 0-49), and menu items and keys are assigned to
|
||
|
|
them. To test whether the event has occured, use the <a href="controller.html">controller</a> test command, like this:
|
||
|
|
<p>
|
||
|
|
<pre>
|
||
|
|
if (controller(c2)) {
|
||
|
|
quit(0);
|
||
|
|
}
|
||
|
|
</pre><p>
|
||
|
|
The above example tests for controller 2 (which could be assigned to "quit" on the menu), and if it has occured, it quits the game.<p>

|
||
|
|
First use the <a href="set_menu.html">set.menu</a> command to create a menu. Then use the <a href="set_menu_item.html">set.menu.item</a> command to add items to it. Repeat this process until all the menus have been set up, and then
|
||
|
|
use the <a href="submit_menu.html">submit.menu</a> command to initialize it, making it available for use. Here is an example of creating a menu:
|
||
|
|
<p>
|
||
|
|
<pre>
|
||
|
|
set.menu("File");
|
||
|
|
set.menu.item("Restart",c1);
|
||
|
|
set.menu.item("Quit",c2);
|
||
|
|
set.menu("Help");
|
||
|
|
set.menu.item("About");
|
||
|
|
submit.menu();
|
||
|
|
</pre><p>
|
||
|
|
The second parameter of the <a href="set_menu_item.html">set.menu.item</a> command is the controller that the menu item is being assigned to. You can assign multiple menu items and keys to the one controller, for
|
||
|
|
example most game functions like save, restore, quit etc. usually have both a menu item and a key.
|
||
|
|
<p>
|
||
|
|
The menu can be brought up using the <a href="menu_input.html">menu.input</a> command.<p>
