I make a snake game but i dont know how to make it running after answer question in matlab app designer

this is my half coding, when i run, it keep on asked first question after i got correct answer

while (1)
    id = 0;
    s_old = s;
    %Update Head Position
    if(app.dir==0)
        s(1,1)=s_old(1,1)-1;
        s(1,2)=s_old(1,2);
    elseif(app.dir==1)
        s(1,1)=s_old(1,1);
        s(1,2)=s_old(1,2)+1;
    elseif(app.dir==2)
        s(1,1)=s_old(1,1)+1;
        s(1,2)=s_old(1,2);
    elseif(app.dir==3)
        s(1,1)=s_old(1,1);
        s(1,2)=s_old(1,2)-1;
    end
    %Update Body Position
    for i=2:1:length(nonzeros(s(:,1)))
        s(i,1) = s_old(i-1,1);
        s(i,2) = s_old(i-1,2);
    end
    %Limit area
    if(s(1,1)>dim||s(1,1)<0||s(1,2)>dim||s(1,2)<0)
        msgbox(strcat('Out of the limits, game ended! Score: ',int2str(app.score)),'End');
        break
    end
    %Touch body
    if(isempty(find(prod(s(1,1:2)==s(2:end,1:2),2)))==0)
        msgbox(strcat('Snake touch the body!, game ended! Score: ',int2str(app.score)),'End');
        break
    end
    %Eating
    if(s(1,[1 2])==f)
        s(length(nonzeros(s(:,1)))+1,1) = s_old(length(nonzeros(s_old(:,1))),1);
        s(length(nonzeros(s(:,2)))+1,2) = s_old(length(nonzeros(s_old(:,2))),2);
        f(1) = round(rand*dim);
        f(2) = round(rand*dim);
        app.score = app.score+1;
        v = v-0.02;
    end
    %Plotting
    app.SCOREEditField.Value = int2str(app.score);
    set(snake,'XData',nonzeros(s(:,1)),'YData',nonzeros(s(:,2)));
    set(food,'XData',nonzeros(f(:,1)),'YData',nonzeros(f(:,2)));
    pause(v)
    %question popped up
    if app.score==1
        question1 = 'Would you like a dessert?';
        title= 'Question 1';
        answer1= questdlg(question1, title, 'Ice cream','Cake','Cake');
        %answer1
        if strcmp (answer1, 'Ice cream')
            continue
        elseif strcmp (answer1, 'Cake')
            msgbox(strcat('Wrong answer, game ended! Score is ', int2str(app.score)),'End');
        end 
        break
    end 
    if app.score==2
        question2 = 'What is 1+1?';
        title= 'Question 2';
        answer2= questdlg(question2, title, '1','2','2');
        %answer1
        if strcmp (answer2, '2')
            continue
        elseif strcmp (answer2, '1')
            msgbox(strcat('Wrong answer, game ended! Score is ', int2str(app.score)),'End');
        end 
        break

在 MATLAB Online 中打开

Your 'break' statements are outside the blocks for wrong answer. The loop would break on any answer, whether its correct or wrong.

To ensure the 'break' command is only executed when the answer is incorrect, you need to move the 'break' statements into the 'else if' blocks as follows:

if app.score==1
    question1 = 'Would you like a dessert?';
    title= 'Question 1';
    answer1= questdlg(question1, title, 'Ice cream','Cake','Cake');
    if strcmp (answer1, 'Ice cream')
        % continue the game
    elseif strcmp (answer1, 'Cake')
        msgbox(strcat('Wrong answer, game ended! Score is ', int2str(app.score)),'End');
        break;  % end the game
    end 
end 
if app.score==2
    question2 = 'What is 1+1?';
    title= 'Question 2';
    answer2= questdlg(question2, title, '1','2','2');
    if strcmp (answer2, '2')
        % continue the game.
    elseif strcmp (answer2, '1')
        msgbox(strcat('Wrong answer, game ended! Score is ', int2str(app.score)),'End');
        break;  % end the game
    end 
end

Also, you can also use an 'else' statement instead of 'elseif' to mark any answer other than the correct answer as wrong. You won't need to define all the wrong answers, only define 1 correct answer and the rest can be wrong. :)
