If you've been following the tutorials, you should have a vague idea of how to write, debug, compile, and run a Processing program. The next section of the tutorial (coming soon!) will dive into more programming topics, but before that, you probably want to know how to actually deploy your program- how do you export your Processing sketch as something other people can execute? How do you convert your code into a runnable program? How do you publish your program, present it, or send it to other people?
There are a couple different ways to export your Processing sketch. You can export it as a runnable application or as an applet, and you can then use your applet in a number of ways. How you export your sketch depends on what exactly your goals are, so we'll go over the different methods that you can choose from.
You don't have to be an expert in any of these, but it's a good idea to be familiar with the different options. Scroll to the bottom of this page for directions on using our step-by-step uploader to automatically create applet, webstart, and runnable jar versions of your game!
Exporting your sketch as an application allows you to create a folder that contains a runnable file that you, or somebody else, can directly run. The benefit of this is that it can be very easy to run without worrying about setting anything else up- the application handles that for you. The downside is that you need to know what kind of computer a person has before sending them a file to download and run.
Depending on what kinds of things you use in your program, you'll have to know what operating system you're targetting, as well as whether the system is 32 bit or 64 bit. To send this to somebody else, you then have to zip up the folder, send them the zip file, have them unzip it, open the folder, and run the application. But if something goes wrong, you won't get very much feedback about why.
You can feel free to export your sketches as applications, but Static Void Games doesn't use that method at all. Instead, I recommend exporting your sketch as an applet and using our step-by-step uploader to automatically generate different versions that other people can use.
An applet is a type of Java program that runs embedded in a webapage. They are generally pretty easy to run, and Processing even generates a webpage that displays the applet for you. If you have access to your own webhosting and some html skills, you can use the files in the applet directory created by Processing and customize your own website displaying the applet. Then you just direct people to that url, and they'll see your applet on the webpage. If you don't want to waste time with html, you can always just use our step-by-step uploader to create a decent-looking game page automatically.
When you export your sketch as an applet, Processing also creates a runnable jar version of your program. This will be located in the applet directory created by Processing when you export your sketch as an applet and will be the name of your sketch with a .jar extension. A runnable jar will work on every computer (or at least every compouter with a JRE, but that's a requirement for every version), and you don't have to specify ahead of time what kind of computer the jar will be run on.
The downside of exporting your program as a runnable jar is that it gets a little bit more complicated if you're using libraries (such as the minim library for sound). Using libraries means that your jar will have to know where the library files are located. This requires you to pass the classpath into the runnable jar every time you run it, which requires you to run the jar from the command line, which isn't exactly user-friendly. The required library files are packaged into jars in the applet folder next to the runnable jar.
If that's confusing, don't worry about it yet. Our uploader handles all of that for you!
A runnable jar can also be deployed as a webstart application. This is similar to an applet in that it is hosted on a website, but the program is given its own window instead of being embedded directly in the page, and security works a bit differently, plus webstart comes with a lot of perks like making sure the correct version of Java is installed.
Webstart applications are also installed on the user's computer just like a normal application, complete with an uninstaller. That way the user has access to your game without needing to be connected to the web. Of course, this can all be customized by the user, which is why many experienced users prefer webstart applications over other deployment methods.
Although webstart applications are how a lot of users prefer running Java programs, setting them up goes a bit outside the scope of this tutorial. If you want more info you can check out [this tutorial](http://docs.oracle.com/ja vase/tutorial/deployment/webstart/index.html), but I would recommend just using this site's uploader, which will set up webstart, applet, and runnable jar versions of your game for you!
This site is designed with the goal of making it easy generate a decent- looking game webpage complete with links to applet, webstart, and runnable jar versions of your game. And you don't have to know anything about html or worry about any underlying Java deployment setup!
The benefit of this is that you get to reach as many people as possible, since different people prefer different types of deployment. So you can focus on programming and improving your game without worrying about html or setting up different kinds of deployment options. Just walk through our step-by-step uploader, and all the boring work is done for you!
To keep things simple, Static Void Games does not support the OS-specific executable applications exported by Processing. And games that require libraries will not be available as runnable jars, that way users don't have to worry about setting up the classpath- just let the site handle that for you and stick with the applet or webstart versions.
When you're ready, just export your Processing sketch as an applet. Then go through the step-by-step uploader and answer the questions it asks you. If your sketch requires library jars, you can specify them too. Static Void Games will then create a game page for you, including links to your game as an applet, a webstart application, and a runnable jar.
