Constrain Scaling To avoid Mirror Efects - New Problem

[BernalCarlos]

Hello,

 

i have already asked this question in the following thread: http://forums.greensock.com/topic/6964-constrain-scaling-to-avoid-mirror-efects/

 

The solution was to set the minScaleX and minScaleY to 0 and that worked, but now I need to constrain the width and height of a transformItem, not the scale. 

 

So, i used the minWidth and minHeight properties of the item. At the beginning its seemed to work, however if I keep scaling beyond the min values, the item will eventually jump to negative scale values.

 

I think its a bug but i don't know, any help will be greatly appreciated.

 

Here a .fla that shows the problem:

Thank you.

Actually, no that's not a bug at all because it is entirely possible to have an object that's a certain width even at negative scale values. For example, if you've got a 100px wide object and you set the minWidth to 50, that means that if its scaleX is -0.7, that would make it 70px wide, thus it's totally "legal". 

 

Believe it or not, it took quite some effort to make that "bug" work that way It is entirely intentional. But if you don't want to allow the scale to go negative, just add these lines:

_transItem.minScaleX = 0;
_transItem.minScaleY = 0; 

Does that clear things up?

ooo I see, sorry for sugesting that it could be bug. But, can is use minWidth and minScale at the same time?, I cant try it rigth now. Thank you Jack.

Yep, you can use them both together. 

 

Have fun

Great, it works.

 

Sorry for the dumb question and thank you very much for your help.

No problem at all. Enjoy.
