Given the player's current position as px and py,
and the directional changes in dx
and dy, update the given grid to change the player's
x-coordinate by dx, and their y-coordinate by dy.
More information:
Use the given w and h (representing the grid's width
and height) to figure out whether or not the move is valid.
If the move is not valid (that is, if it is outside
of the grid's boundaries), then NO change occurs to the grid.
The grid stays the same, and nothing is returned.
If the move IS possible, then the grid is updated
by adding dx to the player's x-coordinate,
and adding dy to the player's y-coordinate.
The new position in the grid is changed to the player
icon '(x)', and the old position the player used to be in
is changed to an empty space '(_)'. The new x- and y- coordinates
of the player is returned as a tuple.
This function does NOT create or return a new grid.
It modifies the "grid" list that is passed into it directly.
