hitting corners

[Mehty]

when Pacman hits the corners it stops but, as an example, if it hits the right corner, if you press the right key it moves right which should not and if you press up or down it moves and stops but it should continue moving upward or downward.

I found it hard to handle the case when the man hits, say the top wall, and still moves continuously to right or left if there is only one variable controlling movement. But the code would look so much more elegant with one moving. Want to know if there is a way to do it. I am now trying to make the man face the right direction...
