A simple animated preloader with a lab flask filling up and a percentage counter at the top. The preloader is built in Flash CS3 and uses ActionScript 2.
To use the preloader in your animations, just copy the movieclip customPreloader in the first frame of your file and add a stop() action on that frame. No actionscript knowledge or coding is required.
If you resize the preloader movieclip, be sure to change the font size of the percentage counter to adjust accordingly. The text uses device font, so it should default to whatever sans-serif font you have on your system. I’ve used Calibri.
