Unity3D答题游戏关卡显示问题：代码放置位置咨询

Hey there! Let's get that level counter working properly. You're on the right track with your levelValue += 1 and UI update code—here's exactly where to place it, plus a few tweaks to make it persist across scene reloads (since you're reloading the scene after each question).

Step 1: Fix Level Persistence (Critical for Testing) #

Right now, your levelValue resets to 0 every time the scene reloads because it's a local instance variable. To keep the level between scene loads, use PlayerPrefs to save and load the value. Update your Start method first:

void Start()
{
    // Load saved level value (default to 0 if no save exists)
    levelValue = PlayerPrefs.GetInt("CurrentLevel", 0);
    // Initialize the level UI immediately
    Level.text = "Level:" + levelValue.ToString();

    if (unansweredQuestions == null || unansweredQuestions.Count == 0)
    {
        unansweredQuestions = questions.ToList<Question>();
    }
    SetCurrentQuestion();
}

Step 2: Add the Level-Up Logic in the Right Place #

Since you want to level up every time a question is completed (regardless of right/wrong for testing), you should trigger the level update right after the user submits their answer. To avoid repeating code, create a helper method first:

private void UpdatePlayerLevel()
{
    levelValue += 1;
    // Update the UI text (string interpolation is cleaner than concatenation)
    Level.text = $"Level: {levelValue}";
    // Save the new level to PlayerPrefs so it persists across scene reloads
    PlayerPrefs.SetInt("CurrentLevel", levelValue);
    PlayerPrefs.Save();
}

Now call this method in both your UserSelectTrue and UserSelectFalse methods, right before starting the transition coroutine:

public void UserSelectTrue ()
{
    animator.SetTrigger("True");
    if (currentQuestion.isTrue)
    {
        Debug.Log("CORRECT!");
    }else
    {
        Debug.Log("WRONG!");
    }
    // Trigger level up after answer is submitted
    UpdatePlayerLevel();
    StartCoroutine(TransitionToNextQuestion());
}

public void UserSelectFalse()
{
    animator.SetTrigger("False");
    if (!currentQuestion.isTrue)
    {
        Debug.Log("CORRECT!");
    }
    else
    {
        Debug.Log("WRONG!");
    }
    // Trigger level up after answer is submitted
    UpdatePlayerLevel();
    StartCoroutine(TransitionToNextQuestion());
}

Why This Works #

• The UpdatePlayerLevel method centralizes your level logic, making it easy to adjust later (like changing to only level up on correct answers).
• Placing it after the answer validation ensures the level increments after the user completes the question, which aligns with your test requirement.
• Using PlayerPrefs ensures the level doesn't reset when the scene reloads, so you can actually see the level increase as you complete questions.

Future Adjustments #

When you're ready to refine the logic (e.g., only level up after 3 correct answers), just modify the UpdatePlayerLevel call: move it inside the Debug.Log("CORRECT!") blocks, or add a counter for correct answers that triggers the level up when it reaches a threshold.
