Question

I’m publishing a swf using ActionScript 3.0 on the web. Therefore, only Flash player 9 or above can run my swf. How can I set the minimal version requirement so that if the use can be notified if his player doesn’t meet my requirement?

Answer 1

Yes you can. As was written in this question, you can get users flash player from Capabilities.version (documentation). The result of this function would be something like this

WIN 9,0,0,0 // Flash Player 9 for Windows

This is a string so i think with like like this

var numbers:Array = version.split(” “)[1].split(“,”);

you can get the array like [9 0 0 0]. From this point I think it should be obvious how to compare if users flash player is good for your flash or not.

So if it’s not, I usually show a picture which says that user need to install new version of the flash player. And if user click on it, I send him to the adobe web page.

Update

One more way in a case if you are using SWFObject to embed your swf. You can set the minimum version there. official docs here.
