Anyway, At the moment I'm attempting to create a basic Pacman Clone for practice. I plan on using this to help me understand programming more and get a stronger grasp on programming for games, as well as strengthening my knowledge of Finite State Machines. At the moment I've only just started creating the basics, and So far I've managed to get an image on the screen, and Now I'm trying to get that image to move about by pressing the arrow keys (UP, DOWN, LEFT, RIGHT). I've tried to use KeyPress, but it won't work (It tells me that a '(' is expected, even if I add One and then click away)
So, Does anyone have some advice on how to do this? I'm using XNA 4.0, conding in Microsoft Visual C# in Visual Studio 2010 Professional.
Here's the Source Code:
