I'm learning pygame (also trying to teach my sons in the ins and outs
of python) and am trying to write a small simple game where a tank
moves around the screen on the user's press of the cursor keys. I've
managed to get this working without the tank turning and without using
an object oriented approach. However, I'm now trying to get my tank
working using the following tutorial [0]. My sprite appears on the
screen and the function move_me is called and changes the value of
draw_pos. However, the tank doesn't move.
It doesn't move on the screen or it doesn't rotate? Did you break the movement when you made it OO?
What is your specific problem?
Is the version of the code on the pastebin the newest version? because if so, your move function is not setting the new position anywhere. It is calculating a new position, printing it out, and then throwing away that value and blitting to the old location.
Also, you shouldn't call a blit function in your move function, you are going to end up double-blitting stuff otherwise. You need to just modify your 'pos' value of the class with your new position, don't calculate drawpos at all.
