How to move from scene to scene? Beginner looking for help.

Hi!

Im beginner with Unity (user for 2 years..) Im making this simple RollABall type of game where you collect pieces to progress. Much like this tutorial:

I need help scripting the scene to chance when you have collected all the pieces. So simple script to move from lvl 1 to lvl 2.

 

Hello,

When all the coins are collected, you can simply use "SceneManager.LoadScene"

You must add your two scenes "lvl 1" and "lvl 2" via File > Build Settings and "Add Current"

Hope it helps.

PS: if you want to keep the score through the scene, you can use "DontDestroyOnLoad" See: http://blog.christianhenschel.com/2013/05/16/how-to-pass-data-between-scenes-static-variables/

 

Hi!

Thx for the reply! Yes this is just what i need. Im just learning C# and JS so i dont really know how to write this down.. Do you have any help on that?

 

You just have to save two scenes, for example "scene" and "scene2", add them in the build (File > Build Settings and "Add Current").

You should have something like this:



And then in your script after you check if all the pieces was collected (in the tutorial, it's in PlayerController class, in the setCountText function, in the if statement) , you can put "SceneManager.LoadScene("scene2");" (dont forget to add "using UnityEngine.SceneManagement;" at the beginning of your script).

 

Ok thx for the help! I'll try this tomorrow. Hope i get it to work.

 

Don't bother with JS because they just dropped code autocomplete in the editor.
My guess is that eventually it'll be tottaly dropped in favor of C#.

 

Hey, so im beginner in C# so these might look stupid..

But here is my PlayerController script:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using UnityEngine.SceneManagement;

public class PlayerController : MonoBehaviour
{

public float speed;
public Text countText;
public Text winText;

private Rigidbody rb;
private int count;



void Start()
{
rb = GetComponent<Rigidbody>();
count = 0;
SetCountText ();
winText.text = "";
}

void FixedUpdate()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");

Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

rb.AddForce(movement * speed);
}


void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag("PickUp"))
{
other.gameObject.SetActive(false);
count = count + 1;
SetCountText ();
}

}
void SetCountText ()
{

countText.text = "Count: " + count.ToString();
if (count >= 8)
winText.text = "You Win!";
SceneManager.LoadScene("Roller_lvl2");
}
}


Im getting 6 errors. "SceneManagement does not exist in the namespace 'UnityEngine'".
I did build the 2 scenes.

 

Any help guys?

 

Someone wanna help me with this? Just trying to advance to the next lvl. What am i doing wrong? (I have the latest v. of unity) Thx.

I did chance the script a little so here is it now:

using UnityEngine.SceneManagement;
using UnityEngine;
using UnityEngine.UI;
using System.Collections;


public class PlayerController : MonoBehaviour
{

public float speed;
public Text countText;
public Text winText;

private Rigidbody rb;
private int count;

public object SceneManager { get; private set; }

void Start()
{
rb = GetComponent<Rigidbody>();
count = 0;
SetCountText ();
winText.text = "";
}

void FixedUpdate()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");

Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

rb.AddForce(movement * speed);
}


void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag("PickUp"))
{
other.gameObject.SetActive(false);
count = count + 1;
SetCountText ();
}

}

void SetCountText ()
{

countText.text = "Count: " + count.ToString();
if (count >= 8)
{
winText.text = "You Win!";
SceneManager.LoadScene("Roller_lvl2");
}
}
}


Remember that im a beginner so i may or may not have done something important to make this work.

AND HERE ARE THE ERROR'S IM GETTING:

 

You have defined a public object using the name SceneManager. Try changing that into SceneManager_OBJ if you are to place an object in there to do .. stuff.
The name is throwing off the compiler i think because it's something being used by unity.

 

You mean like this:

using UnityEngine.SceneManager_OBJ;
using UnityEngine;
using UnityEngine.UI;
using System.Collections;


OR LIKE THIS :

void SetCountText ()
{

countText.text = "Count: " + count.ToString();
if (count >= 8)
{
winText.text = "You Win!";
SceneManager_OBJ.LoadScene("Roller_lvl2");
}
}
}


???

 

No, i'm talking about the

Code (CSharp):

1. public object SceneManager { get; private set; }

.
Also, use the code tags when posting code to make it readable.

 

Hey, i dont really understand what i have to do.. Im sorry. Have chanced my script too many times and i dont know what it does anymore.. It's just not working. Anyway here is my script:


using UnityEngine.SceneManagement;
using UnityEngine;
using UnityEngine.UI;
using System.Collections;


public class PlayerController : MonoBehaviour
{

public float speed;
public Text countText;
public Text winText;
public object SceneManager { get; private set; }
private Rigidbody rb;
private int count;



void Start()
{
rb = GetComponent<Rigidbody>();
count = 0;
SetCountText();
winText.text = "";
}

void FixedUpdate()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");

Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

rb.AddForce(movement * speed);
}


void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag("PickUp"))
{
other.gameObject.SetActive(false);
count = count + 1;
SetCountText();
}

}

void SetCountText()
{

countText.text = "Count: " + count.ToString();
if (count >= 8)
{
winText.text = "You Win!";
SceneManager.LoadScene("Roller_lvl2");
}
}
}

Thx for the effort!

 

You have a line that says "public object SceneManager { get; private set; }"
I've never used that myself. I think you should change the SceneManager into something else, and it should be GameObject. not object.

 

For me, you just have to delete the line "public object SceneManager { get; private set; }".

I've just made a quick test, it's works fine (Unity 5.3.0):

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using UnityEngine.SceneManagement;
4.  
5. public class TestLoadScene : MonoBehaviour {
6.     void OnGUI() {
7.         if (GUI.Button(new Rect(30, 90, 150, 30), "switch")) {
8.             SceneManager.LoadScene("Roller_lvl2");
9.         }
10.     }
11. }

 

Can i please have like a full script would be easyer to understand. Can you just corret mine and well see if it works?

using UnityEngine.SceneManagement;
using UnityEngine;
using UnityEngine.UI;
using System.Collections;


public class PlayerController : MonoBehaviour
{

public float speed;
public Text countText;
public Text winText;
private Rigidbody rb;
private int count;



void Start()
{
rb = GetComponent<Rigidbody>();
count = 0;
SetCountText();
winText.text = "";
}

void FixedUpdate()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");

Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

rb.AddForce(movement * speed);
}


void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag("PickUp"))
{
other.GameObject.SetActive(false);
count = count + 1;
SetCountText();
}

}

void SetCountText()
{

countText.text = "Count: " + count.ToString();
if (count >= 8)
{
winText.text = "You Win!";
SceneManager.LoadScene("Roller_lvl2");
}
}
}

 

As screenname_taken said, please use the code tags when posting code to make it readable.

You wrote "other.GameObject.SetActive(false);", it should be "other.gameObject.SetActive(false);"

It's the only issue I can see.
I can't test the whole script, I don't have the project.

If you still have compilation error, please post a screenshot with the error message.

 

I still get errors here they are:

 

Can you replace "SceneManager.LoadScene("Roller_lvl2");" by "Application.LoadLevel("Roller_lvl2");"?

 

I dont know whats going on anymore... It's all messed up...

 

Here

 

Can you upload the Assets folder of your project?

 

There is only Materials, Prefabs (PickUps) Scenes (Roller_lvl1 and 2) Scripts

 

Scripts: CameraControl, PayerController and Rotator

 

I'll check your scene, the prefabs and all the scripts. Can you please upload you folder Asset in a zip file?

 

There you go

 

In Player in Hierarchy, you must set in the Instpector Count Text and Win Text.

Count Text is in the Hierarchy Canvas>Count Text.
Win Text is in in the Hierarchy Canvas>Win Text.

I check the change scene once you pick all the coins: it works.

 

It still says The type or naame 'SceneManagement' does not exist in the namespace 'UnityEngine' Are you missing an assembly reference. I loosing my mind with this...

 

Seems that you don't have the last version of Unity ...

Delete the first line of the script PlayerController. So delete "using UnityEngine.SceneManagement;"
Clear the console, and run the scene. Should work.

 

That worked... Thank you so much for help! Im sry that this took so long...

 

Only thing is that the second scene (Roller_Lvl2) has different lighting than lvl1. Its a lot darker.
