hi...
I've recently created a dhtml thing on http://www.shapers.nl/ that
animates a lot of images. The thing I want to solve is the lag that
occurs when a new animation is initiated.
To make it time-based I calculate the entire animation on beforehand
and create numerous setTimeOuts in a repeat loop (it's the loop that
creates the lag).
Creating an animation like this has some more disadvantages:
- it's 'difficult' to suddenly end the animation (you'd have to kill
all remaining setTimeOuts)
- setTimeOut is an inaccurate way of animating: the position of an
image might be changed twice per cycle or (the other way around) a
position could change once per two cycles
I need to code something that calculates the position of an image
every cycle. To do this I need the deltaT (= milliseconds between
cycles), and for that I need some sort of event (or workaround) that
occurs every cycle (and works both in IE and Mozilla).
I've tried calculating deltaT with a setTimeOut('getDeltaT()',1) and
with the mouseMove event but both seem slightly inaccurate since they
sometimes return deltaT=0.
anybody got a solution?
grtz...
