This is a port of XNA Game Console by vos - it has been modified to work with XNA 4.0. Some additional changes have been made as well, which can be found in the changelog below.

• XNA 4.0 support
• OS Input - Uses Win32 keyboard input rather than XNA KeyboardState input. This gives a number of advantages, including:
  • Buffered input
  • Paste
  • Auto-detect keyboard layout (I removed the KeyMap class from the original source due to it no longer being necessary)
  • IME-enabled
• Tab Complete - You can now autocomplete to commands by hitting tab
• GameConsole.ExecManual(string command) - Public function that executes man on the string argument
  • Mainly useful for quickly executing man after an invalid argument is passed, or in an exception
• Other Stuff
  • Traverse buffer with mousewheel
  • All commands sent to the console are added to inputHistory, even those resulting in an error
    • Handy so if you typo a command you can correct it by hitting up-arrow
  • Prompt character (Prefix) added to console log when commands are executed, or when no input is supplied
  • con_save now saves to file "con_log" if no arguments are supplied
  • Some of the built-in commands have been renamed
    • info → con_info
    • set → con_set
    • toggle → con_tog
    • save → con_save
    • help → removed from commands

The original console had some very nice looking fade-in/fade-out capabilities, triggered on the GameConsoleAnimation.Fade state. Two floats that some of the fade logic relied on, backgroundAlpha and textAlpha, have been commented out in the code. Alpha values are included in the Color struct starting with XNA4 (as a byte), and I keep animation disabled, so I didn't fix it.
