Text-Adventure si arresta inaspettatamente dopo una determinata linea.

Question

Ho lavorato a un'avventura testuale e tutto procede senza problemi finché non raggiunge una riga di codice. Il mio amico che è molto bravo a programmare non è riuscito a capire cosa c'era che non andava, così ha fatto alcuni test e ancora nessun risultato positivo. Ho bisogno del tuo aiuto perché il suo non era il massimo. Ecco il codice fino ad ora. Prova a testarlo finché non incappi nel bug dove non accetta più input. All'inizio scegli l'ascia, poi scegli l'aiuto, poi si, poi continua, poi smette di accettare.

Il principale Codice classe:

Answer 1

Sei semplice arrivare alla fine del programma. Non c'è nessun altro getInput() o print dopo questo:

print("You swing you sword at the vine,\n It falls to the ground, dead. Do you \n(Continue) To chop wood, or (Go back)\n And confront the old man?"); 

modo che il metodo delle principali uscite, ma non ha ucciso la finestra.

Answer 2

Il motivo per cui si blocca è perché il codice è scritto male :)

Sì, la causa è probabilmente che si dispone di un bug da qualche parte. Ma questo è solo un sottoprodotto del vero problema, che è che il tuo codice è troppo confuso da seguire.

Quello che vorrei suggerire di fare è scrivere in un file di testo o meno così:

{ 
    "1": { 
     "question": "Now, for your first task, choose either (Sword), or (Ax). \n (Make sure you use correct spelling. \n and type only what is in the()s)", 
     "choices": { 
      "Sword": 2, 
      "Ax": 1 
     } 
    }, 
    "2": { 
     "question": "Nice choice. You went for Brute Force, instead of agility.\n Your Quest now begins, with an old traveler that needs your help. \n \"Young traveler. I need you to help me gather wood with your \n new looking Axe.\" Would you like to (Help)? Or Would you like to (Walk Away)?(Remember, Repeat the options exactly,\n or it wont work)", 
     "choices": { 
      "Help": 3, 
      "Walk Away": 4 
     } 
    }, 
    "3" : ...etc... 
} 

poi cercare di capire come ottenere il vostro programma per leggere (Questo è JSON) e utilizzarlo per guidare il gioco.

NOTA: Questo è proprio fuori dalla mia testa, quindi sentitevi liberi di modificare questa risposta se è possibile trovare una soluzione migliore.

Answer 3

La struttura del programma è come un albero, con ogni nodo avere una descrizione e alcune decisioni ramificazione da esso:

  /walk away 
    /ax - help 
start 
     \ sword - race 
       \ face his wrath 

Ad ogni passo abbiamo bisogno di una descrizione e una serie di opzioni

class Situation { 
    String description; 
    Decision[] options; 
} 

Dove ogni decisione ha bisogno di qualche input e conduce ad una conseguenza

class Decision { 
    String expectedInput; 
    Situation consequence; 
} 

Poi la logica del gioco potrebbe essere qualcosa di simile

while (currentSituation.moreToDo()) { 
    currentSituation.describe(); 
    choice = InputHandler.getInput().toLowerCase(); 
    currentSituation = currentSituation.consequence(choice); 
} 

Il metodo describe sarebbe stampare la descrizione ed il ciclo attraverso le opzioni per visualizzare l'ingresso previsto.

Il metodo delle conseguenze controllerebbe la scelta rispetto all'input previsto di ciascuna opzione e seguirà la conseguenza della corrispondenza o visualizzerà un messaggio e tornerà alla situazione corrente.

Il vero divertimento sarà ottenere tutte le descrizioni e le opzioni in quegli oggetti. È meglio leggere da un file che è possibile modificare rapidamente e facilmente (almeno in modo più rapido e semplice rispetto alla modifica del codice).
