Communicating between init and update?

[Ninjadoodle]

Hi Guys

 

Here is a quick question.

 

Normally when setting up  sprite inside a scene's init function I would go ...

 

var ball = new game.Sprite('ball.png');

 

But, what if I want it to communicate with the update function?

 

since "var ball" makes it local to the init function, is there any harm, in not putting var i front of it and making it global?

 

Is this the correct way to do things in panda?

 

Thank you in advance!

I would do it like this:

this.ball = new game.Sprite('ball.png');

Hi @enpu

 

Thank you for the reply! Do I still need to do this if I made an object?

 

Ball = game.Class.extend({

init: function() {

this.sprite = new game.Sprite('ball.png');

this.sprite.position.x = 240*r;

this.sprite.position.y = 160*r;

 

layerFg.addChild(this.sprite);

},

});

 

Then inside the scenes init function ...

 

this.ball = new Ball();

 

What exactly does putting 'this.ball' as opposed to just putting ball?

 

Thank you again in advance!
