allegro trail

hi guys,

i am designing my first game with allegro and MSVS6, it is a simple pacman clone, i have most of it done, but when i move my pacman it leaves a trail

is this a common problem?
how can i get rid of it?

thanks a lot guys.

You have to erase the old one before you draw a new one. Try clearing the screen, or buffer (if you are using one) and redrawing the entire scene every screen.

I remember when I did that one time. Way back when I made my first mode 13h game.
