Nintendo generally doesn't care in the slightest if their assets are used for things like this. In the US and many other jurisdictions Nintendo might care about this is simply fair use. It's an educational resource without even a pretense of monetization, and has been up for years. I don't expect to ever receive a C&D for it.
I started using Respond.js and SignalR to create a little multiplayer game about a year ago, but lost my steam because there doesn't seem to be much to go on if you're just casually learning. Maybe I could give this a try, thanks.
This is very nice. I started teaching my daughter some programming and although I have mixed feelings about JS this is the kind of tutorial that's at the right level and everyone loves Mario.
This isn't actually JS, it's Processing, so the idea is that this will work in the browser by virtue of a library that will run Processing source code in the browser. If you want to do the programming offline, just hit up processing.org, download the IDE, download the codebase.pde file on the same dir as the tutorial's page, and off you go.
It's not js, it's Processing, which is a simplified version of Java with an elegant, simple API for doing graphics and visual art. It compiles to Javascript via Processing.js.
Actually functions or array being objects internally has nothing to do with "object-oriented" as style of writing code. Here it is about style, which is obviously dictated by Processing (and thus Proseccing.js) being ideologically object-oriented. So, well, yeah, it is quite more object-oriented than "proper" code in js, although I don't see why it is such a problem for the person you relply to.
well, close to. Processing is based on Java, but has a simplified syntax, different visibility model, and different scoping rules. Primarily due to how pde source code gets aggregated into a single class which can be compiled to run in the JVM, but because it's not actually Java any non-JVM implementation of a Procesing runner can pretty much ignore Java entirely and simply implement the much simpler Processing interpretation.
