Unity C#保险问答游戏跳题问题排查求助

Hey there! Let's break down why your questions are skipping ahead—this is a super common logic misstep, so you're not alone here.

The Root Cause #

Looking at your SetTextLeft and SetTextRight methods, the problem is that you're using two separate if statements instead of making them mutually exclusive. Here's what happens when you click a button for the first time (when i = 0):

1. The first if (i == 0) block runs: you increment i to 1, update the UI to show the marriage question.
2. Immediately after that, the code checks the next if (i == 1) block—since i is now 1, this block runs too, incrementing i to 2 and switching the UI to the kids question.

You're essentially doing two state updates in a single button click, skipping the i = 1 state entirely. That's why it feels like you're jumping from question 1 straight to question 3/4.

Quick Fix for Your Current Code #

Change those separate if statements to if...else if so only one block runs per button click. Here's how to adjust your methods:

public void SetTextLeft(string text) { 
    if (i == 0 ) { 
        i++; 
        LeftText.text = "Yes"; 
        PlaceholderText.text = "Are you married?"; 
        RightText.text = "No"; 
    } 
    else if (i == 1){ 
        i++; 
        PlaceholderText.text = "Do you have any kids?";
        // Don't forget to update your button texts here if needed!
        // LeftText.text = "Yes";
        // RightText.text = "No";
    }
}

public void SetTextRight(string text) { 
    if (i == 0) { 
        i++; 
        LeftText.text = "Yes"; 
        PlaceholderText.text = "Are you married?"; 
        RightText.text = "No"; 
    } 
    else if (i == 1){ 
        i++; 
        PlaceholderText.text = "Do you have any kids?";
        // Update button texts here too if required
    }
}

A More Scalable Approach #

Since you're building a quiz, it's better to structure your questions in a reusable way instead of hardcoding each state. This makes adding new questions way easier and avoids logic bugs like this in the future. Here's a refactored version:

First, create a serializable class to hold question data (you'll be able to edit these directly in the Unity Inspector):

[System.Serializable]
public class QuizQuestion {
    public string questionText;
    public string leftOption;
    public string rightOption;
}

Then update your main script:

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class ClickingButtons : MonoBehaviour { 
    public Button LeftButton; 
    public Button RightButton; 
    public Text LeftText; 
    public Text RightText; 
    public Text PlaceholderText; 

    // Add your questions in the Inspector!
    public List<QuizQuestion> quizQuestions;
    private int currentQuestionIndex = 0;

    void Start() {
        // Show the first question when the game starts
        DisplayCurrentQuestion();
    }

    void DisplayCurrentQuestion() {
        if (currentQuestionIndex < quizQuestions.Count) {
            QuizQuestion currentQuestion = quizQuestions[currentQuestionIndex];
            PlaceholderText.text = currentQuestion.questionText;
            LeftText.text = currentQuestion.leftOption;
            RightText.text = currentQuestion.rightOption;
        } else {
            // All questions are done!
            PlaceholderText.text = "Quiz Complete!";
            LeftButton.interactable = false;
            RightButton.interactable = false;
        }
    }

    public void OnLeftButtonClicked() {
        // Add logic here if you need to save the left answer
        currentQuestionIndex++;
        DisplayCurrentQuestion();
    }

    public void OnRightButtonClicked() {
        // Add logic here if you need to save the right answer
        currentQuestionIndex++;
        DisplayCurrentQuestion();
    }
}

With this setup, you just add new QuizQuestion entries in the Unity Editor, no more messing with incrementing i and nested conditionals.
