Btw I’m using Fuse in this cause I don’t like doing animations in the timeline. Great stuff you should take a look.

Problem:
So I’m by no means a lazy person and I’d hate to bother someone for some help but I am not exactly super good with actionscript like some of you on here.

So I’m sitting here trying to create an idea for a menu system. I see this type of menu all over the place where once you hover over the section a box or highlight fades in and you can still hover over a button that is over the highlight without making the highlight do it’s out animation once you rollover the button.

I hope you get the idea. So here is what I have tried. I know that the easy way to do this is to create a invisible hit space that calls a function to fade out objects or out animations etc etc. That is what I kind of did with the current file I have. I also tried using a hit test with an onEnterFrame event. This kind of works as well. But I have a feeling that there is a true way without any errors to do this that I am just missing. The hitTest runs to slow for a person with a fast mouse and causes lock up issues on the animations. The current way I have it to doesn’t see the mouse rollover the hit space fast enough, and causes the same issues.

The bottom menu is what I am trying to recreate to a sense. It is for education purposes I see it all over and I wonder the true way of how to do it. Not the easy way with errors.

Your help would be greatly appreciated and I will for sure show others how to do this.
