Forums » Help » Get Entity by ID?

Hello there,

I'm fairly new to Impact and I am working on my first game right now. There were a lot of questions at first but thanks to Google and this forum here I could answer most of them. Unfortunately, I am stumped now.

I am looking for a way to get an entity by its ID - and I haven't found a solution yet. Maybe you can help me?

More context: In the game, blocks are continually falling from the upper edge of the playing field. The player has to click on them, answer a question to make them disappear. There are three block sizes which I have defined in three entity files. The game spawns one of those three entities after a certain countdown.

The game checks over which one the player is hovering and executes a function. It's not working properly though. When I click on one block, another one disappears. That's why I want to get a certain element by ID.

Here's some code.

        kommentar: function(objekt) {

          var Animation = function() {

            animated = true;

            var r = $.Deferred();

            var AnimationTimer = new ig.Timer(1);

            if (AnimationTimer.delta() < 0) {
              objekt.currentAnim = objekt.anims.kill;
            } else {
              AnimationTimer.reset();
            }

            setTimeout(function() {
              r.resolve();
            },1000);

            return r;
          };

          var Kill = function() {
            objekt.kill();
            animated = false;
          }

          Animation().done(Kill);

        },
   
        update: function() {

            if (this.inFocus() == true && animated == false) {
              this.currentAnim = this.anims.hover;
                
                if (ig.input.pressed("leftButton")) {

                  startTime = startTime;

                  var zufall = Math.floor(Math.random()*ig.game.fragenkatalog1.length);

                  box(ig.game.fragenkatalog1[zufall].frage,ig.game.fragenkatalog1[zufall].antwort1,ig.game.fragenkatalog1[zufall].antwort2,ig.game.fragenkatalog1[zufall].antwort1Wert,ig.game.fragenkatalog1[zufall].antwort2Wert,ig.game.fragenkatalog1[zufall].antwort3,ig.game.fragenkatalog1[zufall].antwort3Wert,ig.game.fragenkatalog1[zufall].name); //Hier werden die Parameter für die Box an das äußere JS übergeben

                  //inFocus resetten
                  ig.input.mouse.x = 0;
                  ig.input.mouse.y = 0;

                }
                
            } else if (animated == false) {
              this.currentAnim = this.anims.idle;
              this.anims.kill.rewind();
            }

            if (antwortRichtig == true) {
              this.kommentar(this);
              antwortRichtig = false;
            }

            this.parent();

        },

You could make your own way:

/* in main.js */
getEntityByID: function(id) {
    for(var i=0; i<ig.game.entities.length; i++) {
        if(ig.game.entities[i].id == id) {
            return ig.game.entities[i];
        }
    }
}
