Hangman game

Questions & Answers

Hi everyone, its my first time writing here. I’m currently making a hangman game where it has categories and I’m using text asset for the puzzle thingy. I’m working on only one category since I could just copy and paste and modify the text asset anyway. Now my problem right now is that, in my game scene, it contains a back button and whenever I click on it, words from the text asset gets deleted. This also happens even if I haven’t answered properly or lose on purpose. However, I needed to delete the words from the text asset since whenever the player completes the puzzle category or loses, they will be directed to the scoring scene. I would appreciate if anyone would help me with this. Thank you in advance!

Here’s the game manager script:

If anyone have any questions regarding my game, feel free to ask.

To achieve this, you should separate the initialization of the game from deleting words in the text asset. Initialize the game only once at the start and then handle the back button and game over cases without modifying the words list. Let’s make some modifications to your code:

  1. Separate Initialization and Word Removal: We’ll remove the word removal logic from the Start() method and place it in a separate method called RemoveCurrentWordFromList(). This way, the words in the text asset won’t be deleted when the player goes back or loses the game.
  2. Handle Back Button: Modify the ResumeGame() method to handle the back button. When the back button is pressed, it should go back to the main menu or wherever you intend it to go, without deleting words.
