Re: [pygame] Help - Events

[Henrique Nakashima <henrique.nakashima@xxxxxxxxx>]

Oh, I see. In this case, I would use a variable 'held' to indicate the
tile that is picked up. 'held' would be None if the no tile is held.

When a mouse down event is received, if there is a piece in 'held'
(held is not None), place it. If 'held' is None, then remove the tile
at the mouse location.
