Hi, I'm not sure you're indenting is correct. In your while loop you don't draw anything or update the screen. You should put the updating, drawing, and blitting in every frame. The way you have it, it is only going to do something when you close the window and only once.Your while loop should look like this:

The pygame website has some good tutorials and is a good reference.
Here are some links to help you out:
http://www.pygame.org/docs/
http://www.pygame.org/wiki/tutorials
http://www.pygame.org/docs/tut/chimp...ineByLine.html
Also, you could download some sample games from the website so you can see how they are written and learn from them.

Thanks for the links.Do you you know how to make a part of your image move.For instance to make your hero kick or to shoot.

Do you mean animation? You can't make part of an image move, you need to make seperate pygame.Surfaces. If you want to do animation like walking, running, or shooting you can have a sprite sheet all in one BMP file showing all the possible frames of animation of a charatcer. You can blit the part of the image that you need for the current frame to represent an animation. Is that what you need?
