How do I add a new Property to a Prototype?

[Internetomancer]

I want to add a Steps_Taken property to my events.


I'm using it for a complicated minigame.  I would also like to be able to automatically increment this whenever the event moves, like how it works for Players, but I'm okay with figuring that out seperately.  I really just want to have a new property for every Events Object, which gets created when the event gets created.


What's the best way of doing this?

1. Open your rpg_objects.js with text editor
   
2. Look for 'Game_Event.prototype.initialize'
   
3. Add this variable inside the initialize
   
4. 
   this._steps = 0;
   
   
   Then it should be look like this,
   
   
   Game_Event.prototype.initialize = function(mapId, eventId) {
   Game_Character.prototype.initialize.call(this);
   this._mapId = mapId;
   this._eventId = eventId;
   this._steps = 0; // Your step variable
   this.locate(this.event().x, this.event().y);
   this.refresh();
   };
   
   
   
5. 
   Add this two method below the initialize
   
   
   Game_Event.prototype.steps = function() {
   return this._steps;
   };
   
   Game_Event.prototype.increaseSteps = function() {
   Game_Character.prototype.increaseSteps.call(this);
   this._steps++;
   };
   
   
   Use this script call to get the event's steps,
   
   

   $gameMap.event(eventId).steps()

Thank you!  That's great!  So simple!

1.  
   
2. 
   
3. 
   
   
   
   Game_Event.prototype.steps = function() {
   return this._steps;
   };
   
   Game_Event.prototype.increaseSteps = function() {
   Game_Character.prototype.increaseSteps.call(this);
   this._steps++;
   };
   
   
   
   
   

Quick question, Why you add Game_Character.prototype.increaseSteps.call(this); while it works without it?!!
