Controller

Template:AGIWiki

This article refers controller-command. For information about Controllers as part of an AGI game, see Controller.

The controller command returns TRUE if a menu item or key assigned to the controller has been selected or pressed during the current cycle.

Syntax

controller(ctl cA)

Remarks

Test commands are only valid in an if statement.

This statement can be combined with the NOT operator (!) to test for a controller NOT being selected.

The interpreter clears all controllers at the beginning of each cycle.

If more than one menu or keyboard entry is assigned to the controller, it does not matter which one is selected/pressed. All of them will cause the controller command to return TRUE.

== Example ==

Code:

<syntaxhighlight lang="agi"> //build a simple menu structure set.menu("Info"); set.menu.item("About ", c0); set.menu.item("Help ", c1); set.menu("File"); set.menu.item("Save Game <F5>", c2); set.menu.item("Restore Game <F7>", c3); set.menu.item("-------------------", c20); set.menu.item("Restart Game <F9>", c4); set.menu.item("-------------------", c20); set.menu.item("Quit <Alt Z>", c5); //disable the separators disable.item(c20);

//submit menu to agi submit.menu()

//create keyboard shortcuts set.key(0, 63, c2); // 'F5' set.key(0, 65, c3); // 'F7' set.key(0, 67, c4); // 'F9' set.key(26, 0, c5); // 'Alt-Z'

//test for menu or keyboard selections if (controller(c2) {

 //save game
 save.game();

} if (controller(c3) {

 //restore game
 restore.game()

}

</syntaxhighlight>
