Forums » Help » Storing entity names, Associative array/HashMap?

Hello, I'm making a game, with doors that can be opened with keys, and I would like to store what doors the player has opened. I figured as I add the door entities to the map, I could set their name, then store the name in a controller class to keep track of what doors have been opened already. But I'm not quite sure how to handle this efficiently.

Is there some kind of structure where I can do like ig.game.doorcontroller.add(this.name); to add it to the list then check if the list of doors unlocked contains it in O(1) time when it loads, and if it does to kill itself instantly?

Thanks,
Chris

PS: Sorry, this is my first project in javascript, still learning as I go.

So from what I understand you actually want to kill the open doors the next time the level loads? Or am I way off here?

IF so, why not have an array of open doors in your controller class. Every time a door is opened, you push it to the array. When the level loads you go through the entire array and .kill() every entity inside. Eg:

in Controller.js:

allOpenDoors = new Array();

When the player opens a door (for example by walking into it, in which case this can be in the player's check function):

ig.game.Controller.allOpenDoors.push(other);

in main.js loadLevel, after the level has loaded:

for (var i = 0; i < ig.game.Controller.allOpenDoors.length; i++) {
     var door = ig.game.Controller.allOpenDoors[i];
     if (door) {
          door.kill();
     }
}

(Untested and likely irrelevant if I've misunderstood what your goal is.)

ig.module(
	'game.director.door-controller'
)
.requires(
	'impact.impact'
)
.defines(function(){

ig.DoorController = ig.Class.extend({

	init: function(){
		this.unlockedDoors = {};
	},

	addDoorEntityToUnlockedList: function(doorName){
		this.unlockedDoors[doorName] = true;
	},

	isDoorInUnlockedList: function(doorName){
		if(this.unlockedDoors[doorName])
			return true;
		else
			return false;
	}
  
});

});

I ended up doing something similar to what you suggested. Except I have doors check as initialized if they are inside of the list, if they are, they kill themselves. Each of my doors has a unique name (basically mapname and x and y coordinates).
