How is GUI and Game Program Flow compared to Web programs

Question

I\'ve been developing Web applications for a while now and have dipped my toe into GUI and Game application development.

In the web application (php for me), a reque

There's almost always a loop in all of these - but it's not something you would tend to think about during most of your development.

If you take a step back, your web applications are based around a loop - the Web Server's accept() loop:

while(listening) {
     get a socket connection;
     handle it;
}

.. but as a Web developer, you're shielded from that, and write 'event driven' code -- 'when someone requests this URL, do this'.

GUIs are also event driven, and the events are also detected by a loop somewhere:

while(running) {
    get mouse/keyboard/whatever event
    handle it
}

But a GUI developer doesn't need to think about the loop much. They write 'when a mouse click occurs here, do this'.

Games, again the same. Someone has to write a loop:

while(game is in progress) {
    invoke every game object's 'move one frame' method;
    poll for an input event;
}

... while other code is written in a more event-driven style: 'when a bullet object coincides with this object, trigger an explosion event'.
