Forums » Impact Engine » class level "static" variables

Hi!

I need some way to store sth on class level and not per instance. I found this in the documentation:
http://impactjs.com/documentation/class-reference/class#staticinstantiate-function

But using MyEntity.someVar from an instance of MyEntity does not really work. What am I doing wrong or is it just not possible?

Thanks!

MyEntity.prototype.someVar

How exactly are you trying to access the var? You can't access it with this.someVar, but have to use MyEntity.someVar. E.g.:

MyEntity = ig.Entity.extend({
	doSomething: function() {
		console.log( MyEntity.someVar ); // 42
	}
});

MyEntity.someVar = 42;

Edit: MyEntity.prototype.someVar, as quidmonkey suggested, will access the default value of an instance variable, without instantiating the entity. E.g.:

MyEntity = ig.Entity.extend({
	someVar: 42, // instance var with default 42
	doSomething: function() {
		console.log( this.someVar );
	}
});

console.log( MyEntity.prototype.someVar ); // 42

Hey guys,

thanks for your quick responses! I just noticed them now...

@dominic I almost did it right, but tried to access MyEntity within its own definition context, what couldn't work obviously... Thanks!
