[Solved] Set random Array index equal to other Array index?

Unity Engine

Hello guys,

I have a problem related to arrays and it’s indexes.
The code:

public string [] myName = new string[5];
public Texture2D [] myTexture = new Texture2D[5];
private string curNameString;
private Texture2D curNameTexture;

    // Initialization
    void Start () {
        agent = GetComponent<NavMeshAgent> ();
        curNameString = myName[Random.Range(0, myName.Length)];
        curNameTexture = myTexture[Random.Range(0, myTexture.Length)];
    }

I am trying to make the index of curNameTexture equal to the index of the myName array.

Look - we use myName to choose a random name of our array. Works fine.
Each person has also a picture (Texture2D) attached to that specific array.
So if I would do the following:

curNameTexture = myTexture[Random.Range(0, myName.Length)];

…it doesn’t stay equal to the random chosen number of the myName-array.:face_with_spiral_eyes:
What am I doing wrong over here?
Please, no if statements if possible since I’m going to largely expand this array in the future.

I am a bit confused!

You want curNameString to be equal to curNameTexture.
Well, after you set curNameString to be random, you can say curNameTexture = curNameString and vice versa.
Maybe I didnt understand what you want, but if this is what you are looking for, it is as simple as that

Almost there - I wanted the curNameTexture to be equal to curNameString.
“curNameTexture = curNameString” and vice versa isn’t working that way since you can not connect a Texture with a String.

Below is a simplistic explaining of what should go on, just to clarify:

I solved it by adding two lines. It appears that if you create a third integer and use this one as the Random.Range-thing, you can you use this for both (Texture2D and String) indexes:

//Users Setup:
public string [] myName = new string[5];
public Texture2D [] myTexture = new Texture2D[5];

    private int curNameNumber;
    private string curNameString;
    private Texture2D curNameTexture;

    // Use this for initialization
    void Start () {
        curNameNumber = Random.Range(0, myName.Length);
        curNameString = myName[curNameNumber];
        curNameTexture = myTexture[curNameNumber];
    }

Now it will always show the right Texture to show what the person looks like.

:)Thanks for helping me out. It’s not a false alert, but it bugged me for days.
Now arrays seem to get a bit more logical to me.
