Bone Rush (PyWeek26)

I've been a regular participant in the pyweek contest. The last time i participated, i tried to use cocos-creator to work as editor for cocos2d (python) and was fairly successful in creating a clone of Reigns (a mobile game about making choices).

This time i wanted to replicate the rush fight game, where the faster you tap the faster the game moves. It's pretty fun mechanic and would fit well with the theme "flow". So i got to work with the same workflow i had before, create characters in inkscape and create sprites to be used in game. For a while i pondered about supporting skeletal animation using cocos-creator setup but was not sure if i was going to find time to do it, so i choose to go with sprite animations instead.

Creating the sprites was a big deal as i was not sure if i wanted to setup the character in blender / cocos-creator / Inkscape for capturing the animation images. Inkscape quickly fell apart as an option as there was no way i could keep track of all the animations and modify and create multiple files to be modified later. I had to choose between blender / cocos-creator.. i thankfully ran into another tool called dragon bones. This was pretty good as i could iterate over the animations and generate the sprite frames from the tool itself.

I later used the cocos-creator to setup the scene and played around with fonts and stuff but was able to quickly able to tweak the scene as much as i wanted. I wanted to add additional particle effects etc but was strapped for time and couldn't get it done in time.
The game is called Bone Rush and the above is a video of the game in action.

Unity Game (WebGL) as a Firefox Extension

Firefox is known for its' extensions. That's in fact one of the main reasons people still use it. They had to take a bunch of bold steps in the recent times to stay relavant, like ending support for older extensions, changing the security model and the api.

Firefox  announced a new contest for addons, The Firefox Quantum Extensions challenge. I thought ill' give it a shot. I quickly looked up the documentation for creating an extension and looked pretty simple, there was this game for 2048 i was super excited to put games as extension, quick access short games might workout  i thought.. I wanted to check if i could use my existing game dev tools to create an extension.. hence Unity for FF Extension.

I quickly exported unity game as WebGL and tried loading it as an extension. I ran into issues with something called CSP i don't remember seeing it before but here it was preventing me from loading the unity webgl game as firefox extension. After a bunch of mucking around and not finding any straightforward answer i was able to get it working here it is for anybody else who might be looking for the same.

Three important parts for this (Get the starter code from GitHub)
  • Move the inline script from index.html to a separate file
  • Create a background script for FF addon that will open a new window through "BrowserAction"
  • Allow "blob:" support in the  security policy through manifest.json

Modify the index.html exported by UnityWebGL
The inline script is moved to a separate file called game_loader.js
The next thing to do is to add the right security policy to the manifest.json so that the unity loader can load the script blob.

The background script popuptest.js should be handling the browser action click event to launch a new window and load the games' index.html

With these things done, you should be able to load a unity game exported as webgl should be usable as a firefox extension.

StarLord pen sketching

I was trying my hand at creating famous characters in this new style of characters i've been drawing. Kinda fun exercise to improve this style.

PS: Figured how to embed the pintrest stuff in blogspot.. think it looks good :D

Animating Fights

I love fighting games, love the GodOfWar style action games, aspire to make such a game some time in the future.. have no clue how to though.. a couple of years ago i started writing a python game engine to build an action game using sita sings' blues art style, got a basic demo running but never went any further.

I started to think i should understand the fighting game character animation better.. so started sketching some kicks / punches / weapon attacks.. will probably keep doing this for a while..

All of these done on phone..  once i get a hang of it, should be able to make stuff for a game :D

Animation 18-01-2018


 i found this app called folioscope featured on the appstore. I've always been a fan of tools that let you do traditional animation digitally.

My first experience with this was Pencil2D an opensource QT based tool which was available for mac/windows/linux and can export videos and lets' you overlay on videos and stuff. I tried contributing to that project got a few pull requests merged but that project quickly died out.

The second tool that i came across was blender's grease pencil. This is pretty awesome and has gotten even better in the latest release.

Anyway folioscope, is pretty easy to use and has an amazing set of social features built in i started using it made a bunch of small animations..

 As you can see probably not the best ones but this got me really interested in persueing it further to create more complex / interesting ones.. I even ended up buying a stylus just for this. 

These are some of the more complex animations i created using folioscope.

VUI's impact on Development

Ever since the introduction of computers GUI (Graphical User Interface) has dominated the HCI (human computer interaction) space. This basically required that your development team had a developer + an artist this has been consistent across all development platforms Desktop / Web / mobile.
For the first time in a while we might be seeing that configuration change to a developer + musician or a voice actor to address the new and up coming VUI (Voice User Interface). This just struck me as an interesting change because for most developers art has been a limiting factor, with voice user interface and the voice assistants being able to change their tone / voice on the fly a developer might be enough to deliver an engaging experience for the user.

In other news, my first alexa skill has gone live.. not sure how it will perform as discovery is already a big problem for alexa skills but here is hoping for the best.  Here is the link to my skill on alexa skills store if you are interested "Friend or Foe"

I'm thinking about working on a few other skills hopefully it will be unique enough to get visibility.
