Added difficulty progression, hidden word length change with correct guess

Unreal Courses Show
,
#1

In my implementation the array of valid words is not limited in the number of characters only that the entries are isograms. When each hidden word is chosen the game tests each potential word randomly from the valid array until it gets to one that is 2 plus the player score in length. Each correct guess increments the players score by 1.

At 10 letters long the game tells the player that they have won the game and does not progress further.

If anyone is interested in the detail of how any of this was done respond to the message and I will post my code.

I would love to see your code :grinning_face_with_smiling_eyes:

My code (the text about the dragon is because I imported a dragon mesh into my scene):

	FFileHelper::LoadFileToStringArrayWithPredicate(Words, *WordListPath, [](const FString& Word) {return TestIfIsogram(Word); });

	Score = 0;

	SetupGame();
}

void UBullCowCartridge::OnInput(const FString& Input) // When the player hits enter
{
	ClearScreen();
	PlayerTestWord = Input;

	ProcessGuess();

}

void UBullCowCartridge::EndGame()
