"Locking" a Sprite to another

You just add a check. If the angle is too great, then dont pin it to the behavior, and let it fall off

Depending if you only want the last box to tumble, or the whole tower to break appart.....

Remeber me suggesting, that the platform could also move UP?!

Yes. I see now its actually a good idea. <img src="smileys/smiley9.gif" border="0" align="middle" />

I only want the last box to be able to tumble

well, then pin the others togehter

I tried with applying some physics. so if its within given angle values, it pin them together, if not, I just add a little force to the box, so it "bounces" off.

With some changes, you could unpin all objects and add force to them, so the whole tower would crumble.
