I'm not sure about that. The value last-key-code is only set in the keyPressed method which is invoked when Swing/AWT detects that the user pressed a key. It is only used in the snake-with-key-direction function. After using the value, that function resets it to nil. I understand the desire to avoid global variables whenever possible. I'd really like to find a way to get rid of that global variable, but I haven't been able to. However, in this case I'm having trouble imagining a scenario where something bad can happen. Can anyone think of such a scenario? What would be a better way to capture and use the last key code? -- R.
