We are writing a basic function to simulate the game 2048 and I need help with basic code for the up and down functions. Please in SIMPLE/BASIC matlab writing. We are working with moving rows and columns. I need similar tiles above or below one another to combine and move up or down until they reach a spot in the matrix that is full with a number. Here's our code thus far, if you can incorporate the up and down code writing to fit into our existing script.

A=zeros(4,4);

%% r=randi([1,4],1); c=randi([1,4],1); while A(r,c)~=0 %if the number doesn't=0, generate a new row and column number r=randi([1,4],1); c=randi([1,4],1); end A(r,c)=2;

while A(r,c)~=0 r=randi([1,4],1); c=randi([1,4],1); end A(r,c)=2; disp(A) %% gameover=0; while gameover == 0 B=menu('Direction for movement', 'Up','Down','Left','Right','Quit'); %up=1 down=2 left=3 right=4 Quit=5 %% end

%% %Left if B==3 for row=1:4 for column=1:4 if A(row,column)>0 for sumattempt=1:4-column if A(row,(column+sumattempt))>1 if A(row,(column+sumattempt)) == A(row,column) A(row,column)=A(row,column)*2; A(row,column+sumattempt) = 0; end break end end end end end for row=1:4 Arow = A(row,:); row2 = Arow(Arow ~= 0); [V1,V2] = size(row2); if V2==0 end if V2==1 Arow = [row2(1),0,0,0,]; end if V2 == 2 Arow = [row2(1),row2(2),0,0]; end if V2 == 3 Arow = [row2(1),row2(2),row2(3),0]; end if V2 == 4 end A(row,:) = Arow; end end %% %Right if B == 4 for row = 1:4 for column = 1:4 if A(row,5-column)>0 for sumattempt = 1:4-column if A(row,(5-column)-sumattempt)>1 if A(row,(5-column)-sumattempt) == A(row,5-column) A(row,5-column)=A(row,5-column)*2; A(row,(5-column)-sumattempt) = 0; end break end end end end end for row = 1:4 Arow = A(row,:); row2 = Arow(Arow ~= 0); [V1,V2] = size(row2); if V2 == 0 end if V2 == 1 Arow = [0,0,0,row2(1)]; end if V2 == 2 Arow = [0,0,row2(1),row2(2)]; end if V2 == 3 Arow = [0,row2(1),row2(2),row2(3)]; end if V2 == 4 end A(row,:) = Arow; end end

%Down %Up

%% %Ending the game if B == 5 gameover=2; end %% disp(A) if gameover==0 if A(r,c)==2048 gameover=1; end end

%% %Adding new numbers i=randi([1,2],1,1); if i==1 while A(r,c)~=0 r=randi([1,4],1); c=randi([1,4],1); end A(r,c)=2; elseif i==2 while A(r,c)~=0 r=randi([1,4],1); c=randi([1,4],1); end A(r,c)=4; end disp(A)

%% if gameover==1 disp('You win') end if gameover==2 disp('You lose') end
