Thank you thank you thank you... ... and once more thank you.
I understand how it works, I just had a warped view of the code I was writing. Thanks for the great explanation. Very much appreciated.

There's no problem with the library in relation to nested MCs. The problem with your code on nested MCs is that instead of applying the code to the nested MCs all the time - like you did with the 'un-nested' version - you're applying it sometimes to the MC itself, and sometimes to the nested MCs. Like increasing the _height of the parent MC but then decreasing the height of the parent MC. Think about it this way: forget about mc tween for a while. Instead of applying _y and _height tweens, directly apply values to the properties, as in navBlock3._y = 200; Will it work? In your second case, the nested FLA, it won't, no matter what extension you use, because there are reference problems. So before thinking of fixing problems on the animation, see if your movieclip references are correct. The tween() function works just like assigning values to the properties - so if the references themselves are wrong, there's no way it's gonna work. Anyways, this is your 'nested' code: navBlock1.onPress = function() { if ( this.state == 1 || this.state == 2 ) { this.tween("_height", STATE_HEIGHTS[3], TWEEN_TIME); this.state = 3; trace("closing " + 2 + " and " + 3); navBlock2.navBlockBG.tween("_height", STATE_HEIGHTS[1], 2); navBlock2.state = 1; navBlock3.navBlockBG.tween("_height", STATE_HEIGHTS[1], 2); navBlock3.state = 1; navBlock2.tween("_y", 150, TWEEN_TIME); navBlock3.tween("_y", 200, TWEEN_TIME); } }; Notice you're changing the _height of the movieclip being expanded itself, but when resetting the other two movieclips, you're changing the height of the inner movie. This won't work; you have to use the inner movie or the outer movie for both. So instead, it should be this: navBlock1.onPress = function() { if ( this.state == 1 || this.state == 2 ) { this.navBlockBG.tween("_height", STATE_HEIGHTS[3], TWEEN_TIME); this.state = 3; trace("closing " + 2 + " and " + 3); navBlock2.navBlockBG.tween("_height", STATE_HEIGHTS[1], 2); navBlock2.state = 1; navBlock3.navBlockBG.tween("_height", STATE_HEIGHTS[1], 2); navBlock3.state = 1; navBlock2.tween("_y", 150, TWEEN_TIME); navBlock3.tween("_y", 200, TWEEN_TIME); } }; Also, the other functions (navBlock2.onPress and navBlock3.onPress) have old references, from the un-nested file, so you should properly make it tween the navBlockBG movies instead - properly tweening the _height of your nested navBlockBG instead of just the parent movieclip. In the end, just around one sixth of the code of your second FLA is made for tweening the nested MCs, so it's not gonna work until you go all the way. Again, you can't mix expect to change the _height of a movieclip and expect to change it back by resizing its parent or its child - it won't work properly. If you want to reset the movieclip back, it should reset its own _height. - Zeh _______________________________________________ [email protected] To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com _______________________________________________ [email protected] To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
