disableDrag()

Stops this sprite from being able to be dragged. If it is currently the target of an active drag it will be stopped immediately. Also disables any set callbacks.

Source:

disableSnap()

Stops the sprite from snapping to a grid during drag or release.

pixelPerfect boolean <optional>
 false

 255

If using pixel perfect collision this specifies the alpha level from 0 to 255 above which a collision is processed.
boundsRect Phaser.Rectangle <optional>

If you want to restrict the drag of this sprite to within the bounding box of another sprite, pass it here.
Source:

enableSnap(snapX, snapY, onDrag, onRelease)
