Hi,
I have a script to simulate this classic game. The question is: How can I play many rounds? I was thinking that was using for loop, but I could not find the correct way to accomplish that.
Here the script without repetition:
disp('Stone, Paper and Scissors')
disp('Stone (1)')
disp('Paper (2)')
disp('Scissors (3)')
n=input('Which choice?: ')
pc=[1,2,3];
switch(n)
case 1
MATChoice=datasample(pc,1)
if c1==1
return
end
if MATChoice==2
display('MATLAB win; Player LOSE')
return
end
if MATChoice==3
display('MATLAB lose; Player WIN')
return
end
case 2
MATChoice=datasample(pc,1)
if MATChoice==1
disp('MATLAB lose; Player WIN')
return
end
if MATChoice==2
return
end
if MATChoice==3
disp('MATLAB win; Player LOSE')
return
end
case 3
MATChoice=datasample(pc,1)
if MATChoice==1
disp('MATLAB win; Player LOSE')
return
end
if MATChoice==2
disp('MATLAB lose; Player WIN')
return
end
if MATChoice==3
return
end
otherwise
error('Choose 1,2 or 3')
return
end
return
end
Could you help me, please?
Thank you.

Try this:
numberOfTrials = 30; % Whatever you want...
for k = 1 : numberOfTrials
choices = {'Rock', 'Paper', 'Scissors', 'Quit'};
userChoice = menu('Which choice?: ', choices)
if userChoice == 4
break;
end
computerChoice =randi([1,3])
message = sprintf('You chose %s and computer chose %s', ...
choices{userChoice}, choices{computerChoice})
switch userChoice
case 1
switch computerChoice
case 1
message = sprintf('%s\nTie', message);
case 2
message = sprintf('%s\nComputer wins.', message);
case 3
message = sprintf('%s\nYou win', message);
end
case 2
switch computerChoice
case 1
message = sprintf('%s\nYou win!', message);
case 2
message = sprintf('%s\nTie', message);
case 3
message = sprintf('%s\nComputer wins', message);
end
case 3
switch computerChoice
case 1
message = sprintf('%s\nComputer wins.', message);
case 2
message = sprintf('%s\nYou win!', message);
case 3
message = sprintf('%s\nTie', message);
end
case 4
break;
end
uiwait(helpdlg(message));
end

Use a for loop
numberOfTrials = 15; % Whatever you want...
for k = 1 numberOfTrials
% your existing code.....
end

I thought that too, but when I do that, the script does not ask me again, after one round, about the n option: 1, 2 or 3.
Do you know why is this happening?
Thank you.
