1K Breakout challenge

Attempt 2: 887 876 bytes

Slight minification of my previous version, but the same functionality. Also put into one-liner.

Code: Select all

function S()W,H=G.getDimensions()P,R,T,U,V={x=W/2,y=H-5,w=W/8,h=10},{x=W/2,y=H-18,w=16,h=16},1,0,0;B={[-1]=P,[0]=R}for x=W/20,W,W/10 do for y=10,100,20 do B[#B+1]={x=x,y=y,w=W/10,h=20}end end end;L,Z=love,math;G,K,a,m,M,r,L.resize=L.graphics,L.keyboard.isDown,Z.abs,Z.min,Z.max,Z.random,S;S()function L.draw()if K'a'then P.x=M(W/20,P.x-10)end;if K'd'then P.x=m(W-W/20,P.x+10)end;if K's'and T then T,V,U=nil,-r(4)-4,r(4)-2 end;R.x,R.y=T and P.x or R.x+U,R.y+V;for i=1,#B do b=B[i]X,Y=a(R.x-b.x)-8-b.w/2,a(R.y-b.y)-8-b.h/2;if Y<0 and X<0 then if X>Y then U=-U else V=-V end;B[i]=B[#B];B[#B]=nil;if #B<1 then S()end break end end if R.y>H-15 and a(R.x-P.x)<R.w/2+P.w/2 then V,U=-a(V),m(M(-8,U+r(2)-1),8)end if R.x<5 then U=a(U)elseif R.x>W then U=-a(U)end if R.y<0 then V=a(V)elseif R.y>H+9 then S()end for i=-1,#B do b=B[i]G.rectangle('fill',b.x-b.w/2,b.y-b.h/2,b.w,b.h)end end

As a side note, I wonder if anybody is able to implement some sort of continuous collision detection in the their entry. That would be really cool and make the games more playable (no weird bounces).

Thanks undef for the catch on some extra space!

Nice!
Below 900 bytes, you forgot to delete some spaces next to braces though!

V2 (aka shamelessly stealing ideas from others )

changes:
- no dt
- update merged into draw
- drawing and updating bricks in one loop
- only resizable with conf.lua
- inline one a few variables
- controlled with A and D instead of arrows
- more interesting map
- remove newline from the last line (does it counts?)

count: 845 805 (without conf.lua)

Alright, I stripped down my version.

Extra credit done:

• should scale and be playable on different resolutions (with a conf.lua not included in the script)
• locals

Non minified (1165):

  b = G[2]
  p = G[1]

  function b.c(a,o)
    return a.x + a[1] > o.x and a.x < o.x + o[1] and m.abs(a.y - o.y) < objheight
