      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

2d Game Development - World of Goo physics required

5 posts in this topic

Hi,

I'm a teacher who has a history in programming. I want to begin writing a game which needs the physics of world of goo but not the 3d capability of Unity etc.

If you were to use a development platform like Unity, (or a free one) which would be a good place to start.

It needs to be physics orientated but also able to use / create good graphics.

Thanks for any advice.

So you want a game engine, free, in 2D, with physic capabilities?
Do you want access to the engine code or simply using the embedded editor / scripting language is enough? If not, do you prefer one in C/C++, Java, C#, Python? The language is usually very important as a choice for people.

Wikipedia has a good list of free and open source game engines (also check the freeware section down): [url="http://en.wikipedia.org/wiki/List_of_game_engines"]http://en.wikipedia....of_game_engines[/url]

But to be honest, in 2D I don't know what to recommend. LÖVE seems nice at quick glance but I never heard of it.
Most 2D games actually use a 3D engine and limit action to one plane. Unity and even UDK can be used to create 2D games, but it's obviously not optimal.
What I would personally do is take a 2D graphic library (SDL, SFML, Allegro) and create a quick and simple entity system and also link everything with a physic library (Box2D, etc). Of course, it's a lot more work than using an already existing engine, but it's more dedicated to your needs at the end.

Just for the information, World Of Goo is using SDL for rendering and ODE for the physics, but I just learned that ODE could do 2D physics. He didn't use a pre-made game engine, he made it's own.

Or maybe what you are looking for, as a teacher, if you don't want to teach programming but simply show things, use an already existing commercial game called [url="http://www.algodoo.com/wiki/Home"][u]Algodoo[/u][/url]. It's MADE for education, there's even a special education package. It provide you with a framework to create anything in 2D related to the physic without even writing a line of code! Of course, it's not free, but probably the best choice for you. Check [url="http://www.youtube.com/watch?v=GMrkF47eBlg"]this[/url] presentation video, at least it convinced me :).

For 2D game you can use the Gadget2D engine(http://roswellgames.com/gadget2d/) and use Box2D(http://box2d.org/) for your physics. That should be all you need to attain your goal. All the best. [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]

Thanks for you advice people this is excellent and showing me resources I'm un-aware of.

A little more detail.... I'm hoping to get kids designing games for mobiles (android / iPhone) so want a system that'll easily package up for distribution on those platforms...

Any more advice is very greatly received.

Thanks - Nick

FYI, my old blog (in my sig) details the steps I took to make a game using SFML and chipmunk-physics (another great 2d physics engine). Take a look at it and see if it will help you.

If you want free tools to get kids programming, which will allow them to be able to also deploy to mobile devices, your options on "ease of use" are pretty low. Here are some tools that are free that will provide the first two, free and allows distribution to a lot of platforms, but will have a bit of a learning curve to successfully deploy to a mobile device -

[url="http://www.flashdevelop.org/"]http://www.flashdevelop.org/ [/url]- FlashDevelop is an open source IDE for writing ActionScript code, and includes mobile deployment templates.
[url="http://www.adobe.com/devnet/flex/flex-sdk-download.html"]http://www.adobe.com/devnet/flex/flex-sdk-download.html[/url] - Open source SDK from Adobe for writing/building ActionScript code
[url="http://flixel.org/"]http://flixel.org/[/url] and [url="http://flashpunk.net/"]http://flashpunk.net/[/url] - Take your pick, they're both open source ActionScript libraries that makes making games easier.
[url="http://www.getpaint.net/"]http://www.getpaint.net/[/url] - Paint.NET is basically a free, scaled down version of Photoshop. It rocks.
