Mouse/touch interaction

Move on click

• Move circle to where user clicks (on mouse down)

• Compensating for the size of Sprite.

• Move circle to where user clicks (on mouse up)

Dragging with a mouse

• Click on the circle and drag it.
  • Note that it’s now the circle that’s listening for TOUCH_MOVE events rather than the game. TOUCH_MOVE events happening anywhere but on the circle will not be processed.
