Application Load Level Issue

Unity Engine
1

For the life of me I can’t get Application.LoadLevel(int or string) to load the next level when a button is pushed.

int lvlLoad = 1; // holds the integer value of the level to load (0 = login, 1 = char create, 2 = char select, etc)
					Debug.Log("Loading Level: " + lvlLoad);
					Application.LoadLevel(lvlLoad);

after which the following is returned:

Loading Level: 1

But… alas, nothing loads :frowning:

PS - the index’s are taken from Build Settings also.

Is there a level 1? Those numbers mean nothing until the build configuration is done and they have been indexed. You can also load a level by name with a string.

3

Yes of course.

Edit: Just tried this method as well:

					if (lvlLoad == 0)
						Application.LoadLevel("LoginScreen"); 
					else if (lvlLoad == 1)
						Application.LoadLevel("CharacterCreation");
					else if (lvlLoad == 2)
						Application.LoadLevel("CharacterSelection");

as well as just: Application.LoadLevel(“LevelStringName”);

There could be several reasons for this to happen. I assume you added the scene to the build settings? Does the scene have anything in it?

Do you get any console errors at all?

5

No console errors.

They are in the build settings.

All 3 scenes have something in them, and I can play each scene individually and it works just fine, but the LoadLevel, with string or int - NEVER load :frowning:

I made a test project and I had no trouble switching levels with a button. Do you get the same problem in another project?

7

No.

Would it have anything to do with me using MySQL? I doubt it should, just curious.

Make sure you build your game up with all levels included in the build, this code works for me:

using UnityEngine;
using System.Collections;

public class LevelMaster : MonoBehaviour {

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
	
	}
	
	void OnTriggerEnter(Collider other)
	{
		Debug.Log(other.gameObject.tag + "  " + Application.loadedLevelName);
		switch(Application.loadedLevelName)
		{
			case "Scene1":
			Application.LoadLevel("Scene2");
			break;
			case "Scene2":
			Application.LoadLevel("Scene1");
			break;
		}
	}
}

However, my levels are called Scene1 and Scene2, replace that with the name of your levels, I used cubes as my level switch triggers.

Ok so I commented out all the coding in my button, and just used Application.LoadLevel("Level2"); // Level2 is just an example

and that works fine… quite strange. Are there any certain functions, or bugs I should be worried about if I’m using MySQL?

EDIT:

Solved! In my “MySQL” C# script I was using a public void Close(), changed it to sqlClose() and now it works!

Thanks.

In my current project I am communicating with MySQL by sending a WWWForm to a PHP script. After submitting the form I have no trouble loading levels.

How do you communicate with MySQL? Nothing as far as I know should stop a level from loading unless it causes the program to freeze, or maybe it is waiting/yielding for something?

I actually am using Connecter.NET (well something similar, no PHP files are needed, if you want to take a look PM me some way to get a hold of you, preferably AIM/MSN/etc)

if you do direct connects to DBs just keep in mind that you expose your whole db to any enduser cause the webplayer / standalone runs on their system not your website thus it needs wildcard accounts …
