Hello, I’m trying to make an array in array, so that when I pick one component, I get the corresponding attributes. I only want strings. Like this:

It’s for a school project and I’m pretty stuck now :stuck_out_tongue:
Is there a way to do this in C#? I’m a big noob with Unity at the moment…

What’s the coding course that’s asking people to make question and answer games if you don’t mind me asking? It’s a common enough beginner question that there has to be some large-scale teaching institution that’s decided that having students create a question and answer game in Unity is a great idea.

Looks like you want a custom class containing your data, something like:

public class Question {
    public string questionText;
    public string feedback;
    public string[] answers;
}

And then you can just have an array of those things:

Question[] questions;

Thank you for you quick response! It is working now!

For our school project we have to make a game for primary school students where they learn about safety on social media. Our game is based on flappy bird where they have to choose between two gaps of pipes to fly through and choose an answer.

Just for completeness sake, 2D arrays can be done like this:

string[][]

and 2D lists can be done like this:

List<List<string>>

but for your use case, custom class for clarity is way better

Technically that’s a jagged 2D array. :slight_smile:

A true 2D array is this:

string[,]

C# supports both, but you’re right: it looks like OP’s use case is more for jagged arrays.
