I need a space invaders game. I don't mind if you have anything other in mind or modify this i sent you. It has to be in Visual studio 2008 on C sharp .Net , direct x. Using DX = [login to view URL] AND using DDraw = Microsoft.DirectX.DirectDraw. using [login to view URL] for sounds ofc u can add more reference to the game to make it work the specific zip file that i ve upload contains a space invaders game made using Xna c sharp well i would like to make something like this , ofc not the same using direct x .net i also need to add levels+ sounds + make the rocks into enemies with the ability to fire at me. and add some more futures to make it exciting and cool so things u might be consider are the spaceship ( that can move and fire) the aliens( my rock in the zip) that need to fire as well. and some more futures like Extra points and weapons ofc the game i have its done on xna , well u can get the idea of what i want. so using c sharp .net form applications direct x i would like to have a game like this in case of modification of my zip form xna to direct x form , i would like to make it different look , so it look like a different enviroment.
