I would like to program a computer game which should be played by several participants. And I need to do it in two different ways. The first way is to program a web site where people can login and play. The second way is to have programs running locally and exchanging data with each other using P2P approach.
I know how to program both ways. In the first case I can use PHP. In the second way I use Python or Java. But in this case I need to do the same work twice (using different languages). And I want to avoid that (so, my question is how can I do it).
I almost solved my problem but in the end I have realized that it will not work this way. I wanted to use JavaScripts. I thought that with the JavaScript I can program an interface for the game which reads from and writes to a local file. And then, in the case of the web server I upload and download the local file to the server. And in the case of P2P approach I use Java or Python networking tools to exchange the local files between the user’s computers.
But then I found out that JavaScript cannot read data from a web server. So, my idea failed. Does anybody have better ideas?
That’s not true. You’ll need to use AJAX to query the webserver from the Javascript page. If you’re into Java, have a look into J2EE tutorials, and create your webapp using Java. This way, you can still have a java base for all, and two different interfaces.
