Animation couleur et physique; JavaScript pur, 457 (335) octets
Ceci est mon premier message dans ce forum; J'ai créé ce code et trouvé rétrospectivement ce fil pour le publier.
Voici le code encapsulé en HTML, prêt à être copié / collé dans un fichier html:
<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>
Il a des collisions de pixels parfaits, une physique quadratique précise et des animations de couleurs fluides, le tout en 457 octets de code Javascript hors ligne purement indépendant, montré ici sans plus de détails et d'explication:
<!--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)

</body>
Pour le plaisir, voici une version 1066 octets avec des graphismes plus sophistiqués:
<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>
Est-ce aussi de la triche d'utiliser un système de compression comme DEFLATE?
Ci-dessous se trouve le code ASCII85 pour une version DEFLATEd du code:
Soit dit en passant, il est compressé au total à 335 octets.
