while working app, how can I add canvas ball in app and scroll into place. May be, I can one ball component add the app. after while working, I can copy it. Or I can add new ball component while working app.
You can't create Balls at run time using AI2 blocks.
(Maybe there is an extension for this somewhere)
You could keep a list of invisible Ball components in reserve, but this is good only until you reach your preset limit from what you added in the Designer (aside from what you wisely reused at run time.)
Alternatively, you could draw filled circles at run time in unlimitted number, as long as you keep track of where you put them and their sizes and colors.
