Peepz,
I was looking into how script.aculo.us handles effect to write a
tutorial and for a current project I wanted to make transition between
PAIR effects possible. These PAIR effects are (Appear/Fade,
SlideUp/SlideDown, BlindUp/BlindDown) the effect that toggle can handle.
script.aculo.us calls queue.loop each 40 milliseconds, and that calls
all the effect.loop for all effects in the queue. Then Effect calls
render and calls setup when its idle and calls update (with position)
when its running. *update* does what the effects should do (fade, scale
or move) and its called with the pos parameter 25 times a second. So
know we have a problem, how does one calculate if a effect in the same
queue with the same dom its trying to activate itself during the
previous effect on the same dom.
I think there are 2 things we can do:
- Search the queue each time render is called for a effect and cancel
the queue if the effect is manipulating the same dom and its PAIR effect
of a other. I think this would kill the performance unless the
transition only happens when a option is specified.
- The second think what could be done is, passing on the effect that is
created to make the transition against. This would be much more easy
however it would talk more effect to use it.
What do you guys think? anyone have a other opinion?
Thnx,
Abdur-Rahman
