Spawn Buttons but now?

Hi everyone, so I've done a script for my menu game and I spawned all the buttons level. Now I have a problem, how I can make start the right level when the player taps on a button?

eg. I what to start the level 2 pushing the uttun of the level 2.

Any ideas? this is the spawn code :

Code (CSharp):

1. for (int i = 1; i <= 20; i++)
2.         {
3.             button = Instantiate(icona) as GameObject;
4.             button.transform.SetParent(panel.transform);
5.            }
6.  

thank you

 

Code (CSharp):

1. button.onClick.AddListener(() =>
2. {
3.     // I assume 'i' is the index of your scene
4.     SceneManager.LoadScene(i);
5. });

Didn't test it. Maybe there's a syntax error somewhere, but this is what will work.

 

Doesn't work cause each button load scene 20...

 

Code (CSharp):

1.  SceneManager.LoadScene (SceneManager.GetActiveScene ().name);
2.  

 

it loads the scene of the menu level...

"Doesn't work cause each button load scene 20..."

"eg. I what to start the level 2 pushing the uttun of the level 2."

Your question isn't very clear. So do you mean by "uttun" a button? And you want to assign each button a number, so button 1, 2 and 3 will load scenes with index 1, 2 and 3?

If you want to assign some int value to each of your button listener anonymous method, you can't do that simply using variable i in your for loop. You'll have to have a local variable in your for loop, to which you assign/capture the value of i.

Otherwise you'll end up with all buttons having the last value of i in for loop.

Do a google about C# closures and for loops.

 

there should be a way to attach

Okay, Thank you. Yes, I did a type error, "uttun" means button.

So I looked at some stuff but I really don't know where to start.

 

" I really don't know where to start."

Did you actually read all the above answers and my answer?

 

yes duh.... I looked about closures but I don't understand how to use it

 

But did you actually try to create a for loop similar to what @Dextozz described...?

It alone won't work, but I tried to explain how to fix the issue.

Anyway. Instead of saying you don't understand, could you show your current best effort code.

 

I can't cause I didn't understand how to use the closures!!

 

But did you read what I wrote?

"If you want to assign some int value to each of your button listener anonymous method, you can't do that simply using variable i in your for loop. You'll have to have a local variable in your for loop, to which you assign/capture the value of i."

 

Yes. I also came across this a few months back. I was wondering if this was going to be an issue in my example above. Anyhow, this should completely fix any issues you have.
