I stumbled upon node.js but didn’t understand, then, how to use it in my application.

#Tower defence gbrowser code

The idea of running Javascript code in a non-browser environment was (unbeknownst to me) really picking up steam at that time. For the sake of simplicity and maintainability, it was important that the server-side game code be the same as the game code that ran in the browser. The server-side scoring mechanism was simply to run the game while taking the actions dictated by the user’s log.

Furthermore, there was no way to cheat your way to a high score without having access to a legitimately good game log.

There were typically only a few (<100) of these entries in a given session, and they defined the outcome of the game. The log entries, when decoded, told a story like “at game frame 73, user placed a red tower at coordinates (5, 8)”. The solution I eventually came up with was to send, not just the score, but a log of the user’s actions to the server, and then to score the game in the unperturbed server environment. Any player with designs on cheating needed only to open the browser’s Javascript console to inspect the source code and mess with the game’s internals. In order to block spurious entries, it was necessary to validate the scores submitted from the browser. Picnic Defender had a globally viewable leaderboard. Had I known then what I know now (2014), I would have made better use of non-canvas DOM elements. I employed various tricks to improve drawing performance, such as layering several canvases (so that the background would never have to be redrawn, for example) and only drawing at integer pixel coordinates to avoid unintended (and unconfigurable) anti-aliasing. Hardware acceleration of the canvas element has improved steadily since then, but canvas performance was always a concern when I was working on Picnic Defender. With Firefox 4 and Chrome ~10, web browsers were just starting to come into their own, and canvas was just barely supported. At that time, I had only a cursory knowledge of Javascript, so the project also represented an opportunity to learn the language. It was particularly exciting that I could make a web game while avoiding Flash, with its Adobe spyware, security holes, tendency to steal keyboard focus from the browser, etc. I’ve always liked tower defense games, but there were (are?) no good ones on the web, so I decided to flesh out the project. In the course of an evening, I made some rotating shapes, and then some keyboard-controlled objects moving around, and then a very basic tower defense game. In 2011, I started to hear about the HTML canvas, so I experimented with it. Features which rely on a server (high scores, achievements, multiplayer) are all disabled, but the single player gameplay is fully intact. This is a slightly stripped-down version of the game. For more information, see the project page. My chapter was a tutorial for creating a real-time multiplayer game using websockets in the browser and node.js on the server. I was solicited to write a chapter in the book HTML5 Games Most Wanted when the publisher saw Picnic Defender on Chrome Experiments. Picnic Defender was featured on Chrome Experiments, where it was well-received (rated 4.5 out of 5 with over 150 votes). As an HTML5 application using the Phaser 2 framework it can be played on all common desktop and mobile browsers.Picnic Defender was a browser-based tower defense game making heavy use of HTML5 technologies, including canvas, audio and websockets. Zeppelin Studio managed and executed the technical development of the game. “Data Clash” was designed by the specialists for learning games and gamification Ijsfontein Interactive Media in collaboration with Target Games GmbH and Zeppelin Studio.

Playful education of a complex but highly relevant topic.

Fun, straight forward and fast paced tower defense action.

Data Clash is part of the nationwide information campaign “Your Data – Your Rights” by Digitale Gesellschaft e.V. The browser game Data Clash gives you a compact, simple, and foremost fun overview of all the new consumer rights and the competent management of their data. However, the sheer volume of 11 chapters and 99 articles naturally leads to a lot of confusion for citizens and companies alike. As the name suggests, it is supposed to ensure the rights to protect one’s data and privacy. The so-called General Data Protection Regulation (GDPR) became effective in Europe on. Defend your data packages from tech giants and data kraken and fight for the top spot in the global leader board. Puzzled by all the talk about the GDPR? Make use of your rights to protect your privacy in the fast paced tower defence browser game Data Clash.
