How to alter player hitbox?

[nickypredz]

How would I go about altering the player's hitbox/hit area? I've looked through the documentation but can't see how to implement it.

Edit:

Those looking at this in the future, to solve this:

         this.sprite = this.physics.add
            .sprite(100, 450, 'Player', 0)
            // Reduce hit box size
            .setSize(24, 20)
            .setOffset(8, 12)       

So, to reduce hitbox size you use setSize(px, px) and use setOffset(px, px) if the box moves around
