Physics with touch to move player

[mattbrand]

I am making a maze game where the player drags their finger to control a ball moving through a maze.

I would love to use Phaser physics to block the ball from moving through the walls. Is there a way to do this with Phaser physics and if so, which physics type would be the best suited for this?

This post is related:

P2 is sophisticated enough I think. You could try arcade physics, but  rotational effects are not considered after collision, so the ball will not spin when colliding with walls (it will in P2, see above post). Arcade physics bodies are always axis aligned, which might be undesirable in your case:

Great, thank you so much!

Some jitter during drag :/

I made some serious progress with help from @samme.

Still not sure what to do in onDragUpdate(), where I catch the case where I want to have the ball be released:

if (xDiff > 20.0 || yDiff > 20.0)

But I don't know what to do there in order to disable the ball and re-enable it. You can see my attempts, commented out there.

Anyone have suggestions for how to "let go" of the ball right there, but still have the ball be enabled for input events and drag?

You can try 

sprite.input.stopDrag(pointer);

That is exactly it. Thank you again @samme!
