Hi,
I am making a simple hangman game for a project. I am currently stuck on replacing a "_" and printing the correct letter in place. Can someone please help, parts of my code are below:
wordlength = strlength(word);
hide = repmat(' _ ', 1, wordlength);
fprintf('%s\n', hide);
fprintf("\nThere are %d letters in this word.\n", wordlength);
incorrect = 0;
left = 7;
while (incorrect < 7)
letter = input("Please guess a letter (1 lowercase letter): ", 's');
consists = ismember(word, letter);
if ~any(consists)
incorrect = incorrect + 1;
left = left - 1;
fprintf("\nSorry this is incorrect, you have %.0f guesses left.\n", left);
else
fprintf("This is right!");
hide(consists) = letter
end
end
if (left == 0)
fprintf("\nGAME OVER! YOU LOSE\n");
end
Example:
Lets say there are 6 letters in the word, and the word is 'wizard'. It will print " _ _ _ _ _ _ ".
It then asks for a letter, lets say i type 'w'. It says "This is right!" and shows: hide = 'w_ _ _ _ _ ' . However, It should replace the first '_'.
when it asks for another letter, lets say i type in 'i'. It says "This is right!" and shows: hide = 'wi _ _ _ _ _ ' .
then the third time i type 'd', it says "This is right!" and shows: hide = 'wi _d _ _ _ _ ' .
Thanks.

because
' _ '
are three characters and not 1. first index is space, 2nd is dash and 3rd is space again
what you need is replace the dashes and not the space
for example
if i have
' _ _ _ _ '
The first dash occurs at 2nd index and 2nd dash occurs at 5th index and goes on with 3 index difference
Currently you ve logical index (consists) change them to array index (using find)
For example
A = [1 0 0 1]
B = find(A)
B =
1 4
Or you can replace ismember with strfind
Once you have the index multiply them with three to access every third index and you ve to subtract 1 from them because dash is at 2,5,7,..
PS: Please add a condition for correct answer in your code i.e. if a person guess all the letters stop the game

You don't need to change that aspect, just how you store your data. "If you separate the data storage from the data displaying your code will be much simpler." Take that advice to heart.

I am not sure how to do what you have said above, because I don't have a lot of experience with Matlab, but i think what I have right now is good enough because it works and i need to finish this soon. If i had more time, i certainly would have tried to do what you have said but due to time limitations i'll stick to this.
Thanks for the help.
