Re: [Dynapi-Chat] slide utility

[Richard B. <ma...@ri...>]

Hi,
Checkout the pathanim examples in release 2.55a, you will see the slideTo
function is available there.
You now include pathanim.js and thread.js, when animation is needed.

This was done because thread.js should work as a load-balancer, which gives
all your animations the same priority.

slideBy was dropped, as it was though so simple to do :
myLayer.slideTo(myLayer.getX()+10,null)

Not everyone agreed with this at the time, but that's the way it turned out.
It might be a nice idea to have a official library of addon functions that
work with DynAPI (there is also a nice glide script available), but most
effort is going into browser compatibility, and performance at the moment.

Cheers,
Richard.
