Answer 1

Once an object is drawn in a device context it stays there. If you want to move it you need to redraw it. You can keep a background that's fixed and only redraw the movable elements each time they move. Basically that's how it's done. To move an object smoothly over a line you have to do something like this (I don't have a program ready, so can only give you an idea): choose the start and end position: point A(x1, y1) and B(x2, y2) choose in how much time the object should change position from A to B (say 10 seconds). use a timer set to a certain interval (say 2 seconds) calculate the delta X and Y that the object should change for each timer interval. In this case dx = (x2-x1)*2/10 and dy = (y2-y1)*2/10 in the timer callback increment the current object position with dx and dy and redraw the image That would be the algorithm. I suggest that you also take a look to PyGame. Maybe you can use that and it also has some tutorials.
