Hi there!

I'm wondering how to remove a delayedCall from juggler with removeObject:?

I've been trying something like this:
in My Game.h:
SPDelayedInvocation *factory;
and in my Game.m:
factory = [SPDelayedInvocation invocationWithTarget:self delay:creation_interval]; [self.stage.juggler addObject:factory]; [factory myDesiredMethodCall];
but, obviously, a SPDelayedInvocation does not responds to "myDesiredMethodCall" which is the method I want to call (of my Game.m)...

What I want to do is to remove the delayedInvocation at any time.
[self.stage.juggler removeObject:factory]
Thanks guys!
I'm almost finishing my game!

It's the same as cancelling a tween - use 'removeTweensWithTarget'

As target pass through the object of which the delayed call is a method.

But I already have some other delayedcalls associated with the Game.m (self) so I can not remove all the tweens of self...

I need removeObject: method which allows me to remove only this call.

Thanks a lot, Alex, I had completely forgotten that it does so myself -- LOL!

A better name for the method would have been "removeObjectsWithTarget". Well, too late to change it now

However, MPR, the code you wrote is correct, too! You just have to declare the "factory" object as "id", like this:
id factory; // ... factory = [SPDelayedInvocation...]; [factory myDesiredMethodCall];
Then the compiler won't complain now!

Alternatively, the method "delayInvocationAtTarget:byTime:" returns an SPDelayedInvocation object, which you can remove from the juggler with "removeObject".
id factory = [juggler delayInvocation...]; // ... [juggler removeObject:id];

Ok, Thank you Daniel! it worked!

I'm implementing a custom juggler to deal with a pause/resume system so i'm using dellayedInvocations instead of NSTimers in order to pause this calls and the animations.

Thank you for answering.

Is there any way to suppress the warning I get about "no method found" on the SPDelayedInvocation?

Look at my post above -- you just have to declare it as "id" instead of "SPDelayedInvocation*", then the compiler won't complain.

It complained anyway....actually the message was "might not respond to selector" I eliminated it by just calling "performSelector" with no delay haha.

Ah, the problem might have been that you haven't imported the .h-file that declares the method! I totally forgot that this is necessary, as well.
