Question

If someone has the time I wanted to know if you would be willing to check out my solution file here: http://elvis.rowan.edu/~majeko02/AwesomeShip.zip

I followed the XNA GameStateManagement on AppHub, but nothing comes up from me. and I haven't the clue why.

I believe I done everything correctly and verified it as well.

I wanted to know if someone has the time could they check it out?

I am racking my brain trying to figure out why it doesn't work.

Any help, is greatly appreciated.

Answer 1

You're getting stuck in an infinite loop in your ScreenManager.Update() function.

while(screensToUpdate.Count > 0)
{
    GameScreen screen = screensToUpdate[screensToUpdate.Count - 1];
    if(screen.ScreenState == ScreenState.TransitionOn || screen.ScreenState == ScreenState.Active)
    {
        if(!otherScreenHasFocus)
        {
            //screen.HandleInput(input);
            otherScreenHasFocus = true;
        }

        if(!screen.IsPopUpMessage)
        {
            coveredByOtherScreen = true;
        }
    }
}

You're not reducing the screensToUpdate.Count and therefore it's always greater than 0.

EDIT:
I forgot to mention, if you had just stepped through the code you would have quickly found the issue. Use the debugger often and set lots of breakpoints :)

EDIT 2:
Just noticed the line

GameScreen screen = screensToUpdate[screensToUpdate.Count - 1];

This will cause you issues as well as it's only ever going to update the last screen in your screensToUpdate collection.
