Everyone's been freaking out about that stupid "Flappy Bird" game being removed. So, your task is to crate a Flappy Bird Clone game. Its really simple. Here are the guide lines:

  • It can use either ascii art or real images
  • You can make your "bird" flap with either a click or a key press
  • It should try to be as short as possible, hence the tag.

Here's an example: http://www.reddit.com/r/learnprogramming/comments/1xiimx/i_couldnt_sleep_so_i_cloned_your_flappy_bird/

In order to be a "Flappy Bird Clone," your game needs to have the following:

  • A bird, or other character
  • The "bird" should move slightly up when a key is pressed or you click/tap
  • If there is no clicking/tapping/etc, the "bird" should rapidly move downwards
  • Pipes or other obstacles should move leftwards on the screen, creating the illusion that the bird is moving
  • The pipes should have a small gap for the bird to fly through.
  • Every time you pass through a gap between pipes, your score increases by 1.
  • If you hit a pipe or the ground, the game ends and your score is displayed.

It doesn't really need to be a "bird" or a "pipe," it can all be ascii. Here's a very minimal example of a flappy bird screen:

/-----[4]-----\
| ||      ||  |
| ||      ¯¯  |
| ||  O>      |
| ¯¯      __  |
| __      ||  |
| ||      ||  |

Javascript+jQuery (ASCII Art) - 571 524 491

Open Dev Tools (F12) and run the following code in this page (right now, go ahead!) to make the below demo functional.

l=$('#answer-23452 blockquote pre').click(function(){m=1}),o=[],d=0,e=4,m=1;setInterval(function(){t=Array(153);s=~~(d/10-0.99);d++;d%10?0:o[d+20]=~~(Math.random()*5)+1;for(i=-1;k=o[i+d],i<17;i++)if(k--)for(j=-1;c=j==k||j-k==4?'-':j-k>0&&j-k<4?0:'|',j<9;j++)i>-1?t[j*17+i]=c:0,i<16?t[j*17+i+1]=c:0;m-=.2;e-=m;if(e<0||e>10||t[~~e*17+8])e=4,m=1,d=0,o=[];t[~~e*17+8]='>';r='|-------['+s+']-------';for(i=0;z=t[i]||' ',i<153;i++)i%17?r+=z:r+='|\n|'+z;r+='|\n|-----------------|';l.html(r);},150)

Demo (make it work):

|    --  >     || |
|    ||        || |
|-----------------|

Known minor bugs:

  • If you get a double-digit score, it messes up the layout

  • It is NOT easy!!! (but the original wasn't either)

  • There's a tradeoff between efficiency and golfedness

Feel free to comment with your highscore.

Also, this is my first Code Golf post, so suggestions on compression, etc. will be welcomed

The game replace the question block of this page.
You have to click on the game frame to make the bird fly.

Ungolfed and commented version :

$('#question').children().hide();

$('#question').append('<div id="scene"></div>');
$('#scene').css({position:'relative',margin:'auto',border:'2px solid black',width:'200',height:'320'});

    pipes[i].rightpos += dt*pipevel;
    if (pipes[i].rightpos > 200) {
      pipes.shift();
      i--;
      score++;
      if (score>maxscore) maxscore=score;
      updateScore();
    } else if ((pipes[i].rightpos > 165 && pipes[i].rightpos < 185) && (x < pipes[i].holepos || x > pipes[i].holepos+holesize)) {

      init();
    } else {
      $('#scene').append('<div class="pipe" style="background-color:#000; width:1px;border:1px solid #000; position:absolute; bottom:0; right:'+Math.floor(pipes[i].rightpos)+'px; height:'+pipes[i].holepos+'px"></div>');

  $('#bird').css({bottom:Math.floor(x)-25});

  setTimeout(step, dt*1000);

  setTimeout(addPipe, pipefreq*1000);
}

init();

You can easily modify the configuration (gravity, pipe velocity...), have a look at commented version.

    \$\begingroup\$ With the current control scheme, it's too easy to accidentally misclick and then not be able to fall far enough to get to the next hole (and then being unable to do anything about it). \$\endgroup\$ – Joe Z. Feb 14 '14 at 16:53

    \$\begingroup\$ What I'm saying is that it's too easy to misclick somewhere in the middle, and it's also too hard to click properly because your punch always sets you to the same initial velocity regardless of how fast you've already gone down. \$\endgroup\$ – Joe Z. Feb 14 '14 at 19:05

Color Animation and Physics; Pure JavaScript, 457 (335) bytes

This is my first post in this forum; I made this code and retrospectively found this thread to post it in.
Here's the code encapsulated in HTML, ready to be copy/pasted in to an html file:

<body><script>A=120;B=280;d=document;y=180;x=v=n=s=0;f=140;c=d.createElement('canvas');p=c.getContext('2d');c.width=B;c.height=400;c.onclick=()=>{v-=6};p.font='50px Arial';d.body.appendChild(c);r=(h,t,k=0,i='#0f0',w=40)=>{p.fillStyle=i;p.fillRect(h,k,w,t)};b=setInterval(()=>{if(x==0){n=f;f=Math.floor(B*Math.random());x=160}x--;v+=.1;y+=v;r(0,400,0,'#08f',B);r(20,40,y,'#fc0');r(x-40,n);r(x+A,f);r(x-40,B-n,n+A);r(x+A,B-f,f+A);if(x==60)s++;p.strokeText(s,A,80);if(x>20&&x<100&&(y<n||y>n+80)){clearInterval(b);location.reload()}},15)</script><br>Made by Thomas Kaldahl</body>

It has pixel perfect collisions, accurate quadratic physics, and smooth color animations, all in 457 bytes worth of purely independent offline Javascript code, shown ungolfed here in greater detail and explanation:

<!--entire HTML shell is omitted in golf-->
<body>
    <script>
        //common numbers and the document are assigned shortcut letters
        A = 120;
        B = 280;
        d = document;

        y = 180; //y position of the top of the bird
        x = //x position of scrolling for pipes
        v = //vertical velocity of bird
        n = //y position of the top of the nearest pipe opening
        s = 0; //score
        f = 140; //y position of the top of the farther pipe opening
        c = d.createElement('canvas'); //canvas
        p = c.getContext('2d'); //canvas context
        //set canvas dimensions
        c.width = B;
        c.height = 400;

        c.onclick = () => { v -= 6 }; //apply jump velocity to bird when clicked
        p.font = '50px Arial'; //font for scoring (omitted in golf)
        d.body.appendChild(c); //add canvas to html page
        //draw a rectangle on the canvas
        r = (h, t, k = 0, i = '#0f0', w = 40) => {
            p.fillStyle = i;
            p.fillRect(h, k, w, t)
        };
        //main loop (not assigned to b in golf)
        b = setInterval( () => {
            if (x == 0) { //the x position is a countdown. when it hits 0:
                n = f; //the far pipe is now the near pipe, overwriting the old near pipe
                f = B * Math.random() //assign the far pipe a new vertical location
                x = 160; //restart the countdown back at 160
                //(score increments here in golf)
            }
            x--; //count down
            v += .1; // apply gravity to velocity
            y += v; // apply velocity to bird
            r(0, 400, 0, '#08f', B); //draw background
            r(20, 40, y, '#fc0'); //draw bird (non-default color is omitted in golf)
            r(x - 40, n); //draw first pipe upper half
            r(x + A, f); //draw second pipe upper half
            r(x - 40, B - n, n + A); //draw first pipe lower half
            r(x + A, B - f, f + A); //draw second pipe lower half
            if (x == 60)
                s++; //(this is done earlier on golf)
            p.strokeText(s, A, 80); //draw score
            // if the bird is in range of the pipes horizontally,
            // and is not in between the pipes,
            if (x > 20 && x < 100 && (y < n || y > n + 80)) {
                clearInterval(b); location.reload() //omit interval clear in golf
            }
        }, 15) //(reduced the frame delay to 9, a 1 digit number, in golf)

For fun, here's a 1066 byte version with fancier graphics:

<body style='margin:0'><script>var y=180,x=v=n=s=0,f=140,c=document.createElement('canvas'),p=c.getContext('2d');c.width=280;c.height=400;c.onclick=function(){v-=6};c.style='width:68vh;height:97vh';document.body.appendChild(c);p.font="50px Arial";p.shadowColor='#444';p.shadowBlur=9;p.shadowOffsetX=p.shadowOffsetY=5;function r(h,t,k=0,i='#0f0',j='#0a0',u=0,l=0,w=40){var g=p.createLinearGradient(h,l,h+40,u);g.addColorStop(0,i);g.addColorStop(1,j);p.fillStyle=g;p.fillRect(h,k,w,t);}b=setInterval(function(){if(x==0){n=f;f=Math.floor(280*Math.random());}x=x==0?159:x-1;v+=.1;y+=v;r(0,400,0,'#08c','#0cf',280,0,280);r(20,40,y,'#ff0','#fa0',y+40,y);r(x-40,n);r(x-50,20,n-20,'#0f0','#0a0',n+20,n,60);r(x+120,f);r(x+110,20,f-20,'#0f0','#0a0',f+20,f,60);r(x-40,280-n,n+120);r(x-50,20,n+120,'#0f0','#0a0',n+140,n+100,60);r(x+120,280-f,f+120);r(x+110,20,f+120,'#0f0','#0a0',f+140,f+100,60);if(x==60){s++;}p.fillStyle='#fff';p.fillText(s,120,80);if(x>20&&x<100&&(y<n||y>n+80)||y<0||y>360){clearInterval(b);location.reload();}},15);</script><br>Made by Thomas Kaldahl</body>

Also, is it cheating to use a compression system like DEFLATE?
Below is the ASCII85 code for a DEFLATEd version of the code:
By the way, compressed it is 335 bytes total.

C, 386 351 347 341 bytes (Windows, MinGW), 332 with a terminal emulator

enter image description here

Certainly not the prettiest entry, but it captures the core mechanics of flappy bird: The bird accelerates downwards, pressing a key makes him jump up, touching the pipes or the edges of the screen ends the game, score is the number of cleared pipes.

#import<windows.h>
#define T(x)P[v*10+x]=
char P[71];X,Y,W,s;main(v){srand(time(0));for(float y=1,t=0;!(v<0|v>6|(v<Y|v>=Y+W)&X>0&X<3);Sleep(99)){y+=t=kbhit()?getch(),-.9:t+.3;--X<0?X=8,Y=rand()%3+1,W=rand()%2+2:X-1||++s;memset(P,32,70);for(v=0;v<7;T(9)10,T(X)v<Y|v++>=Y+W?35:32);v=y;T(1)79;T(2)62;system("cls");printf("%s\nSCORE: %d",P,s);}}

It can be shortened to 333 bytes, if a POSIX terminal emulator is used (like Cmder):

#import<windows.h>
#define T(x)P[v*10+x]=
char P[71];X,Y,W,s;main(v){srand(time(0));for(float y=1,t=0;!(v<0|v>6|(v<Y|v>=Y+W)&X>0&X<3);Sleep(99)){y+=t=kbhit()?getch(),-.9:t+.3;--X<0?X=8,Y=rand()%3+1,W=rand()%2+2:X-1||++s;memset(P,32,70);for(v=0;v<7;T(9)10,T(X)v<Y|v++>=Y+W?35:32);v=y;T(1)79;T(2)62;printf("\033c%s\nSCORE: %d",P,s);}}
