Check if two buttons are being pressed at once?

I'm trying to add gamepad support to a game of mine, but due to how limited the amount of buttons on it is, and the fact that I added extra commands to the game(such as fire, drop things,etc) I need a system capable of detecting two buttons pressed at once( and/or one being hold then the other being pressed).

I tried creating an alias for the Scene_Map.updateScene that would check when two buttons are pressed at once, but doesn't seem to work(It detects individual button presses, but not multiple at once). Any ideas?

My code so far:

Code:

var keyconfig_alias = Scene_Map.prototype.updateScene;
   Scene_Map.prototype.updateScene = function() {
     keyconfig_alias.call(this);

       if (!SceneManager.isSceneChanging() && ($gameMap._mapId==1 || $gameMap._mapId==5)) {

       if (Input.isTriggered('weapon')||(Input.isTriggered('fire') && Input.isTriggered('ok'))) {
        ///use weapon

        if(weapondelay===0 && chatopen===false){

            $gameTemp.reserveCommonEvent(2);
        }


    }
     if ((Input.isTriggered('shield') || (Input.isTriggered('fire') && Input.isTriggered('cancel'))) && chatopen===false) {
         ///equip shield
        $gameTemp.reserveCommonEvent(3);
    }
    else if((Input.isTriggered('potion') || (Input.isTriggered('fire') && Input.isTriggered('menu'))) && chatopen===false){
        ///consume potion
        $gameTemp.reserveCommonEvent(7);
    }
    else if((Input.isTriggered('dropweapon') || (Input.isTriggered('drop') && Input.isTriggered('ok'))) && chatopen===false){
        ///drop weapon
        $gameTemp.reserveCommonEvent(8);
    }
    else if((Input.isTriggered('droppotion') || (Input.isTriggered('drop') && Input.isTriggered('cancel'))) && chatopen===false){
        ///drop heal
        $gameTemp.reserveCommonEvent(10);
    }
    else if((Input.isTriggered('dropshield') || (Input.isTriggered('drop') && Input.isTriggered('menu'))) && chatopen===false){
        ///drop shield
        $gameTemp.reserveCommonEvent(9);
    }
          
       }
   };

 

Maybe try Input.isPressed() instead of isTriggered()? I think isTriggered is a single-frame thing, fired when the button is initially pressed down. For comparison, the Conditional Branch check (event command) uses isPressed. Relevant code can be found in rpg_core.js, under Input.

 

That worked perfectly, thank you!
