Group.callAll() question.

[j0hnskot]

Hello! I was trying to change the size of each sprite in the group and i used this: 

this.spikes.callAll('body.setSize',null,10,10,10,10);

it resulted to an error : 

Uncaught TypeError: Cannot read property 'setTo' of undefined phaser.js:51065Uncaught TypeError: Cannot read property 'x' of null phaser.js:50385

but when i did this :

this.spikes.forEach(function(sprite){    sprite.body.setSize(10,10,10,10); },this);

It worked correctly. Where  is my mistake? Why the first way does not work for me?

Got the same problem. Any solution out there?

I don't really remember how i solved it, but try something like  :
this.spikes.callAll('body.setSize', ' body' ,10,10,10,10);

That's it!

I'd in almost every case prefer the forEach method, as if I wanted to add functionality I can just drop it into the callback, rather than rewriting the whole statement.

this.spikes.callAll('body.setSize', ' body' ,10,10,10,10);

this works because you need to specify the context for your call, in this case its the body object.  see the following
