AJAX is used to get a xml file in wherever.
Didn't you see a xml file in files folder? it's very easy and it's weird anyone couldn't understand my .capx
Try to run preview, then open aj.xml in C2, change the numbers to balls and speed whatever you want, then try to refresh browser (do not click preview again in C2) you will understand.
It would work with levels if you try to experiment. Dictionary is just a database of values.
It's designed to update the game WITHOUT editing in C2. Especially for anyone who don't have C2 can edit the game.
I made a post to you according to this thread title "XML for complete noobs" my .capx will explain you how XML works.
Sincerely, if you really want to learn how to use XML, then the result is your ignorance seems rude, i wouldn't to help you again.
