Mac端使用MonoDevelop实现Unity菜单关卡加载功能的方法求助

Hey there! Let's get your level loading script working on your Mac—this is a common mix of small code tweaks and setup checks, so we'll walk through it step by step.

First: Fix the Code Errors #

Looking at your snippet, there are two syntax issues that would break the script no matter which editor you're using:

1. Case sensitivity: C# is case-sensitive, so Public should be lowercase public.
2. Typo: LoadlLevel has an extra lowercase L—it should be LoadLevel.

If you're using a newer Unity version (5.3+), Application.LoadLevel is also deprecated. Here's the corrected, up-to-date code:

using UnityEngine;
// Add this line for newer Unity versions
using UnityEngine.SceneManagement;

public class MainMenu : MonoBehaviour
{
    public void OnClick(int level)
    {
        // For Unity 5.2 and older:
        // Application.LoadLevel(level);
        
        // For Unity 5.3+ (recommended):
        SceneManager.LoadScene(level);
    }
}

Next: Check MonoDevelop & Unity Setup on Mac #

Even with correct code, misconfigured editor links or event bindings can stop things from working. Let's verify these:

• Set MonoDevelop as Unity's default script editor

  1. Open Unity, go to Unity > Settings > External Tools (on Mac, it's in the top menu bar).
  2. Under "External Script Editor", select MonoDevelop from the dropdown. If it's not listed, click "Browse" and navigate to /Applications/MonoDevelop.app.
  3. Close and reopen Unity to apply the change.

• Verify Script Compilation

  1. Open your script in MonoDevelop. Look for red underlines—these indicate syntax errors. Fix any you see, then save the file.
  2. Switch back to Unity and check the Console window (Window > General > Console). If there are compilation errors, Unity won't run your script—fix these first.

• Recheck Button Event Binding

  1. Select your UI Button in the Unity Hierarchy.
  2. In the Inspector, scroll to the OnClick() section.
  3. Make sure you've dragged the GameObject with your MainMenu script into the object field.
  4. Click the dropdown, select your script (MainMenu) then the OnClick(int) method.
  5. Enter the correct level number in the integer field (make sure this matches the build index of your scene in File > Build Settings).

Final Checks #

• Ensure your target scene is added to the Build Settings: Go to File > Build Settings, drag your level scenes from the Project window into the "Scenes In Build" list. The index number here is what you'll pass to LoadScene().
• If MonoDevelop still isn't syncing with Unity, try right-clicking your script in the Project window and selecting Open With > MonoDevelop to force the connection.

That should get your main menu working! Let me know if you hit any snags along the way.
