Hello,
I'm making a game on iPhone using cocos2d, and I have a question.
In my init method I'm doing this :

[self schedule:@selector(newMonster:) interval:1];

It create a new monster every second.
But I'd like that the interval change over time. For example :
-The 10 first seconds of the game: a new monster appears every 1 second.
-Then for 10 seconds: a new monster appears every 0.8 second.
-And after every 0.5 second...

How can I do that?

Thanks !
