P2 physics and body collision callback with world bounds

[MoreK]

Is there a way to set a callback when sprite is colliding with world bounds, when using P2 physics? I need to trigger a sound effect when a ball drops down and hits the world bottom.

 

sprite.body.createBodyCallback does the trick with other sprites, but I couldn't find anything about world bounds. I can create an extra block below the world bound, that would do the trick, but I thought there may be a more sophisticated way to implement this.

Yes, you can use this 

http://phaser.io/docs/2.4.4/Phaser.Physics.P2.html#setBounds

alongside with 

http://phaser.io/docs/2.4.4/Phaser.Physics.P2.html#boundsCollidesWith

and

http://phaser.io/docs/2.4.4/Phaser.Physics.P2.html#boundsCollisionGroup .

Thanks! I assume that after all this you create a callback with createGroupCallback? Sounds a bit complicated compared to sprite-to-sprite collision callbacks but I'll give it a try....

Yes, but personally I would simply create 4 bodies, less headache.
