How do I make the game sleep for 20 seconds. I used Thread.sleep(20000); but it gave me "unreported exception java.lang.InterruptedException; must be caught or declared to be thrown

Making the game sleep
It's easiest to use Greenfoot.delay(...) as JetLennit says, although it will delay by the given number of cycles which depends on the scenario speed. If you need exactly 20 seconds, you can do:
1 2 3 4 | try { Thread.sleep(20000);}catch (InterruptedException ie) { } |
Well, considering an average cycle per second is about 62, so 20.000/62 is about 323
What I would infer from davmac's reply is that Greenfoot.delay will count act cycles while Thread.sleep will use the system clock (in milliseconds).
I think SPower is right.
Yes, you are right. He did ask.
But now I wonder about the math. 20 seconds at 62 frames per second is 1240 frames.
What SPower gave was twenty times milliseconds per frame (not frames per second).
Why do I always do those little things too fast so it's wrong?! Thanks danpost, and sorry for my mathematical error :(
