What would be the best way to make an NSTimer that could pause/un-pause its timing? Subclassing? Containment? Just roll my own with performWithSelector:afterDelay:? That is, if I (my code) creates a (smart) NSTimer with a duration of 5 seconds, then three seconds later I need to pause the timer, the timer should un-pause with 2 seconds left on it, not revert back to a duration of 5 seconds.
Use-case: I have a (fictitious) FPS game in which the players or bots can "damage" the scenery by leaving blast marks. A timer should remove these "decorations" after a given delay, but I want the timers to pause if any players/bots are within line-of-sight of the decorations. The timer should then un-pause once all the players and bots are out of line-of-sight (self-repairing nanotech scenery, anyone?) With a normal timer, you'd have to [<timer> invalidate], and/or re-create a new NSTimer instance, which would reset the time. Another good use is a "smartly" timed weapon/power-up spawn point. If the player (or a bot) is too close, the timer will pause, preventing the spawning of the weapons/power-ups, but as soon as no players or bots are close by, the timer will resume, and a new weapon or power-up will spawn there. This would discourage "camping" around known spawn points! :) Or has this "wheel" already been invented? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
