I need to create timer countdown animation on the 3d plane,
after reading this http://away3d.com/forum/viewthread/2694/ , first what comes in mind is “spritesheet” animation , but if i’ll need create for example 2 hour countdown it will be a quite large sprite sheet, which most likely will cause memory issues.
Is there a better way to to that?

thanks a lot!

A solution is highly depending on the design. So unless you provide sketches, it’s hard to guess what you want to achieve.

For instance when you say “i’ll need create for example 2 hour countdown, it will be a quite large sprite sheet”
Why? I mean all you need is “0-9” and may be a “:”,  no?

ok, it’s not really what i needed,
whole time value like ’ 13 hours 12 minutes 15 seconds’ supposed to be on the single plane, but making just “0-9” makes much more sence =)) 
just have to change some things to make it work!
Thanks alot Fabrice!
