This feature reveals the HiddenWord “Wheel of Fortune” style. If the HiddenWord was “cakes,” it would be revealed as: c####, then c#k##, etc.

I included a new private declaration in the header file to store this:

FString PartiallyRevealedHiddenWord;

I then created this function that accepts the user’s guess w/ a fully-commented version below:

FString UBullCowCartridge::DetermineCorrectlyGuessedLetters(const FString& Guess) const {
    FString CorrectlyGuessedLetters = "";

    for(int32 i = 0; i < HiddenWord.Len(); i++) {
        if(PartiallyRevealedHiddenWord[i] != '#') {
            CorrectlyGuessedLetters += PartiallyRevealedHiddenWord[i];
        } else if(Guess[i] == HiddenWord[i]) {
            CorrectlyGuessedLetters += Guess[i];
        } else {
            CorrectlyGuessedLetters += "#";
        }
    }

    return CorrectlyGuessedLetters;
}

//returns an FString, accepting a reference to an FString that promises to not be modified, and promises to not mutate any member variables
FString UBullCowCartridge::DetermineCorrectlyGuessedLetters(const FString& Guess) const {
    //create an empty FString to build upon
    FString CorrectlyGuessedLetters = "";

    //for each letter in HiddenWord
    for(int32 i = 0; i < HiddenWord.Len(); i++) {
        //if the PartiallyRevealedHiddenword at the same index is already revealed, add it. 
        //This keeps Bulls revealed even if User guesses incorrectly on future tries.
        if(PartiallyRevealedHiddenWord[i] != '#') {
            CorrectlyGuessedLetters += PartiallyRevealedHiddenWord[i];
        //else if the user gets a Bull, add it
        } else if(Guess[i] == HiddenWord[i]) {
            CorrectlyGuessedLetters += Guess[i];
        } else {
        //else the user guessed incorrectly and keep the letter hidden
            CorrectlyGuessedLetters += "#";
        }
    }

    return CorrectlyGuessedLetters;
}

I chose to reveal the first letter of the hidden word to the player to make the game a bit easier, but I also included a round-system that cranks up the difficulty as the user guesses correctly. Round 1 starts the player with a 4 letter word, then increases by 1 for each round reached, up to a maximum of 5 rounds.

Okay thanks an awesome idea! How did you figure out how to make this?

First I thought about what I wanted the feature to do. Then I thought about the knowledge I already had and if I could accomplish it with that. This is a pretty simple feature so the few CS courses I took in college were enough to get me there logically. Any syntax or other issue I may have come across I just
Google-Fu until I find something that works.
