Sorry I was able to see this only now.
maybe he just wants to practice his JavaScript? lol
this is context-dependent, details:
risultato is always undefined because the interpreter only waits between commands. You will have to check the response in a different place, e.g. in another event command.$gameMessage.setChoiceCallback(function(n) {
// store selected index in game variable ID 1
$gameVariables.setValue(1, n);
});@JessIchigoShadow: can you also show a screenshot of where you are calling this function in your game?
I see some potential problems:
(I'm guessing this is the basis for an item storage system.)
- Context -
thisis context-dependent, details:
Your function should be run in the context of the interpreter that you want to pause.this - JavaScript | MDN
A function's this keyword behaves a little differently in JavaScript compared to other languages. It also has some differences between strict mode and non-strict mode.developer.mozilla.org
- Timing -
risultatois alwaysundefinedbecause the interpreter only waits between commands. You will have to check the response in a different place, e.g. in another event command.
- Scope - because you need to check the response elsewhere (Timing), I suggest storing the response in a game variable instead, e.g.
JavaScript:$gameMessage.setChoiceCallback(function(n) { // store selected index in game variable ID 1 $gameVariables.setValue(1, n); });
Negozio function into 2 new functions, e.g. (untested):(function() {
var oggetti = [
'Pozione',
'Acqua magica',
'Erba curativa',
'Stimolante',
'Pozione dell amore',
'Zanne velenose',
'Filo di tela'
];
function Negozio1() {
$gameMessage.add("What do you want to put in?");
$gameMessage.setChoices(oggetti, 0, -1);
$gameMessage.setChoiceBackground(0);
$gameMessage.setChoicePositionType(2);
$gameMessage.setChoiceCallback(function(n) {
// store selected choice index in game variable 1
$gameVariables.setValue(1, n);
});
this.setWaitMode("message");
};
function Negozio2() {
var index = $gameVariables.value(1);
var itemName = oggetti[index];
if (itemName) {
$gameMessage.add("You chose " + itemName);
$gameMessage.add("How many do you want?");
}
};
})();Function#call to call those functions in the interpreter context:◆Script：Negozio1.call(this);
◆Script：Negozio2.call(this);

setWaitMode should be called in a new command. This lets the interpreter wait for the player to make a choice before checking what that choice was.Oookay, thank you!
