body touching callback?

[veggis]

I have a class that extends phaser.sprite, and in update i want to do something to the object that its body is touching.

Is there a way to get the sprite/object from body.touching?

.. If that makes sense.

I'm pretty sure 

body.touching

never cares to check to see what it's touching.  

In order to do this, you'll probably want to add all the sprites that you want to affect by touching to a group, then call 

game.physics.arcade.collide(sprite, group, function(sprite, collidedSpriteFromGroup) {
  //affect collidedSpriteFromGroup here
});

inside your update loop.

This example uses overlap instead of collide, but it's effectively the same thing:
