Among the first things that needs to be improved (appart from the graphics!) is the key handling... specificaly, the wait should be cut in sub waits with key checking to allow more movements per 'cycles'... ```DoesNotFit(game, piece, p) // return true if piece does not fit begin local j; if game(im(p), re(p)) then return 1; end; for j:=1 to size(piece) do p:= p+piece(j); if game(im(p), re(p)) then return 1; end; end; return 0; end; EXPORT Tetris() BEGIN local game= makemat(J=1 or J=12 or I=1 or I=25,25,12), pause=0.200, score= 0; local shapes= {{(1, 0), (0, 1), (-1, 0)}, {(1, 0), (0, 1), (1, 0)}, {(-1, 0), (0, 1), (-1, 0)}, {(1, 0), (1, 0), (0, 1)}, {(-1, 0), (-1, 0), (0, 1)}, {(1, 0), (1, 0), (-1, 1)}, {(1, 0), (1, 0), (1, 0)}}; // Bar while 1 do local piece=shapes(randint(6)+1), p=(5,2), i, j; // get a random piece if DoesNotFit(game, piece, p) then return score; end; // test if we lose // create background dimgrob_p(G1, 320, 240); dimgrob_p(G2, 320, 240); line_p(G1,99, 0, 99, 232, #FF); line_p(G1, 99, 232, 202, 232, #FF); line_p(G1,202, 232, 202, 0, #FF); for i:=1 to 23 do for j:=1 to 10 do if game(i+1,j+1) then rect_p(G1, j*10+91, i*10-9, j*10+100, i*10, #0); end; end; end; while NOT DoesNotFit(game, piece, p) do // Draw the background on back buffer blit_p(G2, G1); // draw the piece i:=p; rect_p(G2, i*10-(-81,19), i*10-(-90,10), #0); for j:=1 to size(piece) do i:= i+piece(j); rect_p(G2, i*10-(-81,19), i*10-(-90,10), #0); end; // draw backbuffer on screen blit_p(G2); // pause wait(pause); // keys? if IsKeyDown(37) then if NOT DoesNotFit(game, piece, p-1) then p:= p-1; end; end; if IsKeyDown(39) then if NOT DoesNotFit(game, piece, p+1) then p:= p+1; end; end; if IsKeyDown(33) then local rotate= piece*(0, 1); if NOT DoesNotFit(game, rotate, p) then piece:= rotate; end; end; // try to go down... if DoesNotFit(game, piece, p+(0,1)) then break; else p:= p+(0,1); end; end; // put piece in game! game(im(p), re(p)):= 1; for j:=1 to size(piece) do p:= p+piece(j); game(im(p), re(p)):=1; end; // remove lines? for i:=24 downto 2 do if game(i)=[1,1,1,1,1,1,1,1,1,1,1,1] then for j:=i-1 downto 2 do game(j+1):= game(j); end; game(2):= [1,0,0,0,0,0,0,0,0,0,0,1]; score:= score+1; i:= i+1; end; end; // faster! pause:= pause-0.001; end; END;``` Edited: 20 Nov 2013, 2:54 a.m. Re: Simple Tetris. free for you to improve on - Erwin Ried - 11-20-2013 Is this a demo how to hang the Prime? Trying to run it I get invalid input, and it reboots the calculator when stepping (also crashes the emulator) Re: Simple Tetris. free for you to improve on - Mic - 11-20-2013 J'ai une erreur entrée non valide à l'exécution. Re: Simple Tetris. free for you to improve on - Erwin Ried - 11-20-2013 By the way... I added txt support in my small utility, full hpprgm support, multiple file upload :) so this tetris is a perfect example for the little video... but since it does not work :/ https://www.youtube.com/watch?v=FxG-R0QZ-qI
