Cancel subscriptions?

[BasomtiKombucha]

Hi,

let's say I'm crating an interactive button. That means I need to listen to MouseEvents, or some kind of its equivalent that pixi has (I'm not sure how this works).

The button exists for a while, and once I don't need it anymore, I remove it. My question is: do I need to remove the event listener/cancel subscription/whatever as well?

 

Take a look at this code: 

var button = new PIXI.Sprite(texture);button.buttonMode = true;button.interactive = true;stage.addChild(button);button.click = function(data) {    console.log("CLICK!");}stage.removeChild(button);button = null;

Is it ok, or will it memory leak?

Your method is correct, this is how it's normally done.

Setting button to null does not delete the button though, be careful with that. The only way to get "rid" of it is to allow it to be garbage collected AKA removing each and every reference made towards it.

 

But that is more of a general JS discussion, not exactly Pixi. Disabling the sprite's interactivity, as far as I know, removes the handlers too.
