How to make sure that my blocks stop when it reaches the border?

And also, the the random shape will be generated again?

Judging from the code you have posted, a game like Tetris is way beyond your current abilities IMHO.

I suggest you work on some simpler projects first.

So are you the same person under a different screen name as from this post?
Or did you just take that persons code for your own?
It's funny that you're asking the same question, too...

What is up with all the Tetris questions all of a sudden?
