We can't magically tell you how to do something. For 1, you didn't use the buttons at the top when you were making your thread so we don't know what verison of VB.Net you're using. Secondly, we don't know what kind of "shooting" you want. Do you have a side scroller? Player at the bottom? Player on the side? Player in a space ship?

You also didn't tell us if you're using DirectX, OpenGL, or GDI+ to make your game and you didn't supply any source code making it seem like this might be a homework assignment and you want us to do the work for you.

Please give us more information and show us what you've done for your game so far (and whatever attempts you've made thus far for your shooting).

I'd also like to add that we having a game programming forum, which this would probably be better suited in.
