SVG as level description file

If you ever wanted to use svg as a level editor for your HTML5 games.. here is the basic code you can use. Obviously you have to make sure that your svg file is using only rects instead of any other type if you want to use this code as is.. But its' a good basic start for getting you started. I've used the color of the rects in svg to determine how it behaves in game.. you could offload it to the editor (i.e inkscape in my case) to add properties to the rects which can be read and used to determine properties.

$.get("drawing.svg", function(res){
//loading the data from an svg file.
blocks = [];
user = null;
ball = null;

var $layer = $(res).find('g').first();
//get all the rectangles in the level and create the list.
$layer.find('rect').each(function(){
//string operations to get the color set for the block.
var fillstyle = $(this).attr("style").split(';')[0].split(':')[1];
var x, y, w, h;
x = parseInt($(this).attr('x'));
y = parseInt($(this).attr('y'));
w = parseInt($(this).attr('width'));
h = parseInt($(this).attr('height'));
if(fillstyle == "something"){
}else if(fillstyle == "something"){
}
});
});

ps:///$.get() is the jquery call, so you need jquery to run this as is.. or you could handle the xmlhttp request thing ..

Epic Games Store on Steam Deck

EGS ( Epic Games Store ) like it or hate it, has been giving away free games and if you like free games you would have picked up atleast a couple of them. So given that some of those games are Deck Verified / Playable, its fair to assume you would like to install the EGS on the Deck. Installing EGS on Steam Deck Switch to Desktop Mode on your Steam Deck Download the EGS installer for windows from the Epic Store website: https://store.epicgames.com/en-US/download (using your web browser of choice) Open Steam in the desktop mode and add the installer as a non-steam game In the browse window, switch from .desktop files to All files. Select EpicInstaller-xxx.msi and add it to steam library. Find EpicInstaller in your steam library and open its' properties by hitting the "Gear" icon on the right ...

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...
