Just now configured my blog with Twitterfeed.
So this is post just to test the setup. :)

EDIT : Yup..its working !!

Biggest day of my life (until now) !!!

Hi everyone !!

Today I am so so happy and want to share this news with you all. As I mentioned in one of my previous posts, our game RICKSHAW BRAWL won an award for Best ART n DESIGN in Intel Level Up 2010 - India Series and the final result for the International Series was due for 15th December.
Well, the results are out and have just now received a mail from Intel saying,

"Congratulations! Rickshaw Brawl has been chosen as the student winner for the Judges’ Choice award for the “Best Graphics Performance” in the Intel Game Demo Challenge: Level Up 2010. We had over 847 games registered from 32 countries this year."



Yes...you guessed that right. RICKSHAW BRAWL once again bags an award internationally, competing with 847 games and this time for the BEST GRAPHICS PERFORMANCE :D

Student category winners list

And whats the icing on the cake ??? We get a Boxed Intel® Core™ i7-940 Processor. Yippeeeee !!!!!

This is how our first 3D game makes a mark in the gaming world. Really excited about this. And hopefully, RICKSHAW BRAWL will continue its journey to evolve into a full version game and become one of the best game titles :)

Three cheers for our team !!
Hip Hip Hurray! Hip Hip Hurray! Hip Hip Hurray!

A dream trip to the NASSCOM Animation & Gaming Conclave 2010

Hello friends! I would like to share with you one of my biggest achievements so far. RICKSHAW BRAWL, as I mentioned in my earlier post, was selected among the top 10 finalists in the Intel Level Up 2010 India series and was invited to be showcased at one of the biggest events for game developers and animators in India – NASSCOM Animation & Gaming Conclave 2010 in Hyderabad. And yes, I was able to make it to the event after crossing so many hurdles :P thanx to my friend Ankit :)



The first day of the summit was for Animators. Unfortunately I couldn’t attend it. Nevertheless, we were there on the 2nd Day. The day was packed with lots of interesting presentations by speakers from leading organisations like Ubisoft, Adobe, Intel, Kreeda Games and many more. We attended many of them and it was really great to hear such inspiring minds. Though, we were in the game lounge playing games most of the time :)

The final event – “The Gaming Super Pitch”, where I had to present our game RICKSHAW BRAWL in front of the Judges, started at around 5:30 pm. After all the game presentations and a lot of questioning by the judges and audience, it was finally time for the results. And I am really happy to announce that RICKSHAW BRAWL won the prize for THE BEST ART & DESIGN. We won a laptop from DELL. So well done DC Animations. You guyz really did a great job. Wish you were there with me.






It was such an awesome experience for me. I got to talk with some really great people from EA, KREEDA GAMES, INTEL and many more. I had never got such an exposure and this event turned out to be a great opportunity for me to showcase my work and interact with such cool people from all over India.

Once again thanx to Intel for the wonderful opportunity, thanx to Ankit for coming with me. And last but not the least, well done team. Awesome work !!

RICKSHAW BRAWL ROCKS !!!

Bouncy - Silverlight Version

Heres a Silverlight version of the game BOUNCY. I made just to get the feel of Silverlight, Blend and C#.

Rickshaw Brawl done for Intel Level Up 2010

Hello all! Blogging after such a long time. The past month was really tight packed with lots of tasks to do, one of which was the INTEL LEVEL UP 2010. Well, for those of you who don't know what that is...Its a game development competition held by Intel every year. And fortunately one of the Idea that I submitted, got selected for the Demo Round. Credits to Sagar bhaiya for the awesome idea. That game is - RICKSHAW BRAWL.



I, along with my animator friend Ravi and his team, have been busy developing the game for the past 1 month. This has been my first experience with 3D Game development (actually finished a game :P) after thinking of jumping to 3D Game dev from Flash for a long time. And I must say, it was pretty good for a first one. :)

Moreover, as a boost-up, our Game Rickshaw Brawl has been selected among the TOP 10 games in the LEVEL UP - India Series and invited to be showcased at the NASSCOM Animation & Gaming Summit 2010 in Hyderabad. Cheers to the whole team for that !!
Well, its still a question if I'll be able to attend it or not :P Lets see.

The Game would be available for download in the coming days, probably on my new site. So keep watching the Blog for further announcements.

The final international results for the LEVEL UP will be out in December. So pray for us :)

And Happy Diwali !! (a little late here)

Box2D Experiment

I have been exploring BOX2D physic engine for past few days. Its really great to work with once you understand its basic working. I made up this small demo showing some of the basic features of BOX2D.

Enjoy the physics :D

My first experience with PAPERVISION 3D!

Hello all !

I am back with something new..and this time its PAPERVISION 3D - The awesome 3D library for flash. This is what I created to explore it.

My first tutorial - How to make a simple ball game in AS 3.0

Here it is guyzz !! The much not !(awaited) tutorial by me on my blog. This tutorial is basically for all those people who are passionate about game development, specially in Flash, but did not knew how to start off. Doing this game tutorial will expose you to the basic flow of a game and how the elements of the game interact with each other.
Well without much talk lets start off the business.


What are we going to develop ?

In this tutorial we'll go through the procedure to develop a basic game similar to my game BOUNCY.


What are the pre-requisites ?

1. Adobe Flash CS3 or higher


2. Basic knowledge of Actionscript 3.0


3. Basic understanding of OOPS concepts

But how how how ?

So here starts the real game development. This tutorial is divided into 2 parts:
PART 1 and PART 2.

PART 1

The first part will discuss the basic ball movement and collisions.

Fire up your Flash IDE and open a new AS 3.0 file

Create 2 Movieclips for Ball and Ground each. You can name them anything you like.

Draw simple shapes for the 2 movieclips (circle for ball and rectangle bar for ground). Finally drag them
to your stage from the library and name them ball_mc and ground_mc.

Now create 2 Actionscript files : Game.as and Ball.as and SAVE YOUR WORK.

Game.as Code :
Open the Game.as file and put the following code :

/*
Game.as
*/

package{
 import flash.display.MovieClip;
 import flash.display.Sprite;
 import flash.events.*;
 import flash.geom.Point;
 
 public class Game extends MovieClip{
  var GRAVITY:Number = 0.5;
  // elasticity coefficient
  var E:Number = 0.7;
  var EPSILON:Number = 0.7;  
  
  // ctor
  public function Game(){
   addEventListener(Event.ENTER_FRAME, gameLoop);
  }  
  
  function gameLoop(e:Event):void{
    var radius = ball_mc.width/2;
    var forecast_x = ball_mc.x+ball_mc.speed_x;
    var forecast_y = ball_mc.y+radius+ball_mc.speed_y;
    
    // relection of ball from left and right sides   
    if((forecast_x-radius < ground_mc.x-ground_mc.width/2) || (forecast_x+radius > ground_mc.x+ground_mc.width/2)){
     ball_mc.speed_x = -(ball_mc.speed_x*E);
    }
    
    // calculate the contact point
    var pnt:Point = new Point(ball_mc.x, forecast_y);
    // convert it to stage cordinate system
    pnt = this.localToGlobal(pnt);
    // check collision of ground and ball contact point
    if(ground_mc.hitTestPoint(pnt.x, pnt.y)){
     ball_mc.speed_y = -(ball_mc.speed_y*E);
     // if y-speed is very small...stop it
     if(Math.abs(ball_mc.speed_y) < EPSILON){
      ball_mc.speed_y = 0;
      // add friction as ball rolls on ground
      ball_mc.speed_x *= 0.85;
     }
    }
    else{
     ball_mc.speed_y += GRAVITY;
    }
    // move the ball after making all calculations
    ball_mc.move();     
  }  
 }//eof class
}//eof package

Code Explanation :

1. 
   This class is the Document class of our game. Just incase you dont know how to attach a Document class :
   [ To attach a Document class : Click anywhere on empty stage and open property panel. Put the class name in the Document Class: text box. ]
   
   We declare 3 variables :
   GRAVITY : As the name suggests, it is the amount to add to ball's y-speed while in air.
   E : This variable defines the elasticity co-efficient for the collision between ball and ground.
   EPSILON : Its the smallest amount of y-speed that ball can attain before coming to rest.
   


2. 
   Next we define the class constructor. Here we add an event listener for every frame (MouseEvent.ENTER_FRAME).
   
   The listener function is called gameLoop().
   


3. 
   Now comes the core function of our Game class..gameLoop().
   The first 3 lines calculates few things. The radius of ball, the ball's next x coordinate (current x + x-speed) and similarly its next y coordinate (current x + x-speed + radius).
   
   Notice that we add radius while calculating forecast_y so that we get
   the bottom contact point instead of center of ball.
   


4. 
   

   
   // relection of ball from left and right sides   
   if((forecast_x-radius < ground_mc.x-ground_mc.width/2) || (forecast_x+radius > ground_mc.x+ground_mc.width/2)){
    ball_mc.speed_x = -(ball_mc.speed_x*E);
   } 
   

   
   We then check the collision of ball(Ball_mc) with the left and right boundaries. In this case we take the boundaries as the end of our ground. The collision is a simple check that if the x coordinate of the leftmost point of the ball goes , beyond the left and right extremes of the ground, we reverse the x-speed of the ball. Simple...isn't it ?
   



5. 
   

   
   // calculate the contact point
   var pnt:Point = new Point(ball_mc.x, forecast_y);
   // convert it to stage cordinate system
   pnt = this.localToGlobal(pnt);
   

   
   To calculate the collision between ball and ground we check if the lowermost point of the ball is hitting the ground or not.
   The function that serves our purpose is hitTestPoint(p:Point) which takes in a Point class object.
   
   But the thing to notice here is that this function needs coordinates in the global space i.e. in the Stage coordinate system. So we transform the point (ball_mc.x,forecast_y) to stage coordinate system through the function localToGlobal().
   [ localToGlobal() : This function takes in a Point Class object and return the cordinates in the coordinate system of the calling object. ]
   
   We get the point to check in variable pnt.
   



6. 
   

   
   // check collision of ground and ball contact point
   if(ground_mc.hitTestPoint(pnt.x, pnt.y)){
    ball_mc.speed_y = -(ball_mc.speed_y*E);
    // if y-speed is very small...stop it
    if(Math.abs(ball_mc.speed_y) < EPSILON){
     ball_mc.speed_y = 0;
     // add friction as ball rolls on ground
     ball_mc.speed_x *= 0.85;
    }
   }
   else{
    ball_mc.speed_y += GRAVITY;
   }
   

   
   This is actual code where we check the collision between the ground and ball's lowest point that we now have in pnt. The hitTestPoint() called from ground_mc takes in the coordinates of the point to check for collision.
   
   If the hitTestPoint() returns true (Collision occured), we simply reverse the ball's y-speed after multiplying it with E (cooefficient of restitution).
   
   Note here that as E is less than 1, multiplying it to the y-speed decreases it. After several such bounces the y-speed becomes lesser and lesser and the ball kind of vibrates on the ground due to very small y-speed.
   The situation is shown below. To see more clearly, RClick on the swf, Zoomin on the contact point.
   
   
   
   To correct this problem, we put a restriction on the bouncing through an if condition. We check if the magnitude of y-speed of the ball has reached a predefined amount defined by EPSILON (a small number) variable.
   When the y-speed becomes less than EPSILON, we stop the ball.
   
   Also we add friction to the ball when the ball stops by just decreasing the x-speed of ball (by multiplying with cooefficient of friction).
   



7. 
   Finally, we call the ball's move() in order to move it. The move() function of ball will be defined later in this part.
   

Ball.as Code :
Open the Ball.as file and put the following code :

/*
Ball.as
*/

package{
 import flash.display.Sprite;
 import flash.events.*;
 
 public class Ball extends Sprite{
  
  var speed_x:Number;
  var speed_y:Number;
  
  // ctor
  public function Ball(){
   speed_x = 0;
   speed_y = 0;  
  }
  
  function move():void{
   this.x += speed_x;
   this.y += speed_y;
  }  
  
 }//eof class
}//eof package

Code Explanation :

1. 
   This is a very simple class for the ball in our game.
   
   Firstly we declare 2 variables : speed_x and speed_y. Their use is simply what they mean. Not much here.
   
   Next is the constructor which initialises the two speeds to 0.
   



2. 
   Lastly, we define a function called move() which was called from within the Game.as as we saw before. This function just updates the position of the ball by adding the speeds to the current position.
   
   Dats all !
   

This is all we need to do to embed collision and basic movement of ball in our game.

Now save your work and run your flash movie (CTRL + Enter).
You should see something like this :



What to expect in PART 2 ?
Well, PART 2 is not much of a tutorial. Its a small part of the game that is left as an exercise for you guyzz. The only thing remaining in our game is to code the ball's mouse interaction. Our ball (ball_mc) should bounce when we click on it.

The readers are recommended to write this code themselves. And incase you are not able to do it, don't panic. I'll be posting the solution snippet in the coming days. Till then try to play with the codes given here and make it more of a complete game by putting elements like :

1. Scoring system


2. Game Menus


3. Better graphics

Your comments are most welcome. They'll help me to write better tutorials in future.

Happy Flashing !!

Awesome people. Inko dekh k hi feel aati hai >:D

AVENSIS 2010

Avensis 2010 - our technical fest ended day before yesterday. Ye pehla fest hoga 3 saalon mein jismen maine itna kaam kiya hai :P Well this fest thought a lot of things. Most importantly I learned some skills of MaNaGeMeNT (One thing I hate the most). Reason - I along with my friends Ankit,Anshul,Nishant and Shobhit organised the first ever online event in MSIT's technical fest this year. And yes we named it BRAINSTORM >:D



BRAINSTORM ran for 9 long days involving participation of 300+ students from various colleges. Those 9 days were really a great experience for me and I guess for my friends too :)
We had quite a fun doing it. Posters print karana, college main idhar-udhar chipkana, internet pe prachaar karna (Marketing is really a tough job :S), 9 days constantly web system ko monitor karna, forum update karna, bugs and problems handle karna...pheww. Not to forget one thing which really kept us busy for a few days........DESIGNING QUESTIONS for BRAINSTORM. Humari sach main watttt lag gayi thi doin that :D

Apart from BRAINSTORM, one more thing this fest gave me is a 3rd Win (though not 1st position this time :D hehehe) for my best game till date.......CHEF OF WAR (COW). I won the 3rd prize for COW in SOFT-IMPACT at Avensis. And that was my 1st presentation i guess o_O

Finally all ended with the closing ceremony and pakodaaass :) Will suffer for one more year waiting for AVENSIS 2011 :D Till then hope COW wins 3-4 more times.hahhehehe

Back from TECHFEST 2010 @ IIT-B

Hi all. I m bak from the Asia largest technical festival. Yes, I m talking abt IIT-Bombay's TECHFEST. This year it was much much bigger than last time. More food, more stunt shows, more technoholix, more events, more food, more friends and still more food.[Foods gotta be the main attraction of any place..rite :)] So lets begin the 3 Techfest days.
DAY 1
We were alloted the best place in complete IIT-B campus ->> The SERVANT QUATERsss :D The specification are as follows : 24 hour running water from a tap (literally), 2 rooms with mattresses in them, bathroom with no water facility :P All thanks to our 12 hour late running train, other hostels were full. Chalo jaise taise we managed the 1st night. Subah-2 hum nah-dhoke nikle to check out the wonderful IIT and techfest. We went to recieve our jugadoo frnd kartikay who arrived der by flight just to do NOTHING :) Humne kisi tarah use accommodation dilayi humare saath hi and the we spent the day eating and roaming here and der. Finally the technoholix night 1 came and as usual yeeeeeeeee lambiiiii line :P but thanx to kartikay we entered technoholix thru a secret entrance and managed to see the awesome event dat night. The mountain bikers were really cool. Then we went to the nearby food court and had some stuffff after which we went bak to ouur cool room at abt 2am.

DAY 2
The day 2 started with me waking up at 9. Anurag (btw I went to bombay with my frnd anurag) was still sleeping. I got ready and left for the 10am flash gaming competition. We had to play gravity masters der and I stood 1st in it :) though I didnt got anything for it as they ran short of prizes :P. Then after having breakfast me and anurag went for our VIRTUALPRO competition where we gave the presentation on our 3 games after which we went to eat. BTW, before thhe competition we were at aqua zone where kartikay stood 1st in a pool coin game...hahaha. he was just awesome in the pool :) After resting for a while kartikay and anurag left IIT to see some outside places. I stayed and saw the technoholix night 2 from outside though :P. Finally I met my frnd ROHIT from IIT-BHU at hostel 6 with his other frnds out of which 2 were IITians (IIT-b) and guess what..??? Der ranks were 50 and 73 :D De were Himanshu and PARO :) Really nice guys. We all (arnd 12 guyz) went out, had real fun, gupshup ki, ate a lot, party ki and finally at arnd 4 am we went bak to our cool room to have a lil sleep.
DAY 3
Day 3 started with the wait for the VIRPRO results and yes I WON. CHEF OF WAR won again :)
We had some food and left for the place where we were given our certies and prize. We came to our room kept our stuff, packed our bags and left for anurag's cousin's house in powai itself. At night we went out with his big bro for an outing and had dinner. And so ended our DAY 3.
Next day hum subah uthe MALL main shopping karne gaye vapas aaye and left for dadar station jahan train chutne se just 10 min pahunche pe hume pata chala ki train 8 ghante late hain :P Will kya tha...8 ghante khate peete waiting room main guzara. and then main yahan hun :)

This 1 week experience is what will keep me goin the whole damn year which is to come. Yahi wo time hai jab aap really TECHNOLOGY ko kareeb se dekh sakte hain bundled with fun, food and awesome people.
I hope I b a part of TECHFEST 2011 too.
This is chang signing off. BYEE.
