InkScape As Level Editor

I have been working on creating a simple game engine for 2D games which would use pymunk (chipmunk) 2D physics engine and currently undecided tool kit for windowing. I was working on creating a simple loader for loading info from the svg file to create game objects. I have done this successfully you can see the code at http://code.google.com/p/noobix/source/browse/#svn/trunk/proto.

It's a no brainer that we have to add the meta data required for game engine to the objects in svg file, but adding all that Game Engine related info to the SVG objects can be a little tedious.. esp if you want to have many objects in a level. So I've been trying to look at making it a little less painful.. guess what.. inkscape extensions are pretty awesome for doing just that. I quickly put together a simple inx file which inkscape uses for creating gui for the extensions. Im' pretty excited about this now.. Really cool..

.. i have been trying to get the extension to work but for some weird reason it wouldn't... so guess what.. i just copied an extension which was already there.. and started editing it to make it mine :) ... and it worked!! oh well.. guess i missed something really trivial.. but its' working now and is up in the code base.. next i have to think about how to get the model info in there. for separating out rendering from the other stuff..

Flash animations in GoDot Engine

If you have not heard about GoDot game engine,.. you should check it out right away.. godotengine.org Last time, i wrote a blog post about my experience making a simple physics game to GoDot Engine. Though there are a bunch of free options announced during the GDC this year, i thought ill' contribute to the engine. The one piece that is most important for game dev is the pipeline for the engine. One of the most common tools used for 2D animations is Flash. I have been using a library called Super Animation for almost all the games we've made for android at TMG. It's a free tool which lets you convert swf files to .sam files. This file can then be loaded in Cocos2Dx using the Open source loader library https://github.com/raymondlu/super-animation-samples I thought it would be a good idea to port this cpp library to GoDot so that i understand how to write custom modules for the engine. This is the video of the module in action. I have expos...

Vehicle Physics (Godot 2D)

I've always been fascinated with the vehicle physics used in games. I played so many racing games / the hill climb games and every single time i would wonder wow that must be really hard to do. Thanks to the new generation of game development tools, developing physics based games has become almost a second nature to most people. I didn't want to be left out so i gave it a shot.. I tried setting up vehicle physics in GoDot Engine for a 2D vehicle. Here is what the vehicle scene looks like.. 2D vehicle setup in GoDot As you can see the body collision shape is not right but the rest of the stuff just works. The idea is simple think of what parts move along with the body vs what doesn't. I was kinda stuck setting up the pinJoint2D in GoDot, it actually clearly takes two nodes under the properties. This makes sure that the wheels are hinged to the DampingSpring2D. The Damping Spring2D takes two physics bodies(Body and the PinJoint2D) and makes it work like shock ab...

Gif Animation in Gimp

Ever wondered how to make a gif animation using gimp?? Hmm ofcourse you did.. well even if you did not.. it would be good to know how simple gif animations can be made in this Free image editing software. Here is a sample of what can be achieved. Yes it looks crude.. but i made it in less than 20mins.. so i guess its valid :) any way.. coming to how we do it.. open gimp, create a new image, press ctrl+l this will bring up the layers dialog. In this layers dialog you are provided options to create delete, move the layers. So keep adding layers, each with the next image in the animation sequence. Want to check how your animation looks?? go to filters->animation->playback this will launch a dialog box which has playback, rewind and step buttons on it. Click on playback button and you will see how your animation looks. Satisfied?? just save the animation with an extension ".gif" ..you have to note that while saving you will be asked if you want the different layers to be mr...
