Simplepause

[TheUnknownCylon]

The what: This branch demonstrates the possibility of a pause function for the OpenRA game engine.

The why: when playing with a friend or family member, it is sometimes desired to pause the game. For instance to get a drink or something to eat, when the phone rings, etc. Pausing the game will not ruin your life then, and it also won't ruin your game.

The how: the usage is very simple now. During the game, one can press the PAUSE key on the keyboard, and the game will pause. The game can be un-paused by pressing the key again.

In the background the following is done to make this work:

• The client sends PAUSE GAME REQUEST to the server.
• The server replies with PAUSE GAME to all clients.
• From now on, the ordermanager.tick() will not be invoked
  Note: pause messages are immediate orders (so one can unpause).

Some remarks:

• Orders can be given, but are queued. The UI will not update these orders until the game un-pauses.
• It has been tested with 1vs1.

Possible future extentions:

• Adding a pause option in the game-menu (for keyboards without a pause-key)
• Freeze the game with a "pause screen", where the user can un-pause, resign, chat, and change settings
• By the game-creating adding a setting which enables/disables the pause-option.

I have added some notes to your commits. Generally looks good.

Check that your timer stuff doesn't clash badly with the KOTH ui, which also shows just below the timer.

Does the pause/unpause work properly in replay?

[chrisforbes]

Let's have this on F3 as well. Not everyone has a hardware PAUSE key anymore.

Chris, I'll continue working on it next weekend.
As far as I can tell: replay seems to work fine (it does not replay the pause, but it replays the pause 'chat'-messages).

I've put this ticket in the release milestone for this Saturday. I'd
like to ship it then.

Have done some testing, seems to work great.

Hi Chris,

Sorry for the delay. Is there still work to do? Or is it all finished yet?
I have looked into the paused-display. I have problems solving the KOTH-paused-placement. To me it seems that the circle in KOTH is drawn by the OpenRA.Mods.RA, and the pause-text by OpenRA.Game. It think it is not possible (and should not be possible) for the OpenRa.Game to know whether the game is KOTH or not. Therefor it can not calculate an alternative height for the pause-text.

Possible solutions are: MM:SS (paused)
MM:SS\n\n(paused)

The first one does not fit in a 800x600 window.
The second one does look ugly in normal game.

I have time Wednesday to make the proper adjustments. Please let me know.

800x600 is below the minimum resolution anyway. The UI is set up for 1024x768 or higher.
