   Hi all,

   When i pause my game, i'd like to pause the director's drawings BUT i'd need to keep one timer alive so that it keeps getting events on a server.

   It looks like both pause/resume and startAnimation/stopAnimation also unschedule all TImers.

   It prevents me of keeping some background tasks running and cocos2d says no to use NSThread but its own timer so it stuck with that.

   Any idea?

   thx

   You may modify CCDirector on the next way:
   Add CCNode* variable to CCDirector, set its property isRunning to YES, and visit it onEach tick in [CCDirector mainLoop].

   CCDirector.h
   

   @interface CCDirector : NSObject
   {
     ...
     CCNode *alwaysRunning;
   }
   @property (retain) CCNode *alwaysRunning;

   CCDirector.m
   

   @synthesize alwaysRunning;
   
   - (id) init{
     ...
     alwaysRunning = [[CCNode alloc] init];
     alwaysRunning.isRunning = YES;
   }
   
   - (void) mainLoop{
     ...
     [alwaysRunning visit];
   }

   Now, when you want to run timer you may use next code:
   

   CCSequence *sequenceAction = [CCSequence actions:
           [CCDelayTime actionWithDuration:0.5],
   	[CCCallFunc actionWithTarget:self selector:@selector(methodCallTimerExpired)],
     nil];
     [[CCDirector sharedDirector].alwaysRunning runAction:sequenceAction];

   or run action for any node which must be add to [CCDirector sharedDirector].alwaysRunning:
   

   CCNode *tempNode = [[CCNode alloc] init];
     [[CCDirector sharedDirector].alwaysRunning addChild:tempNode];
     [tempNode runAction:sequenceAction];

   In other words, you says that it's not possible in cocos2d as is ..!
   that's some tweaking but that's a good idea. i'm going to give it a try
