Unity Multiple Toggle Buttons Reversing

Question

I am making a unity project. The situation is that I have two toggle buttons (actually more than two) toggle1 and toggle2 and two gameobjects cube1 and cube2. On start both the toggles are unchecked and gameobjects are SetActive(false). What I want is if both buttons toggle1.isOn && toggle2.isOn then cube1 SetActive and if toggle2.isOn && toggle1.isOn then cube2 SetActive according to toggle orders i.e. which toggle is selected first. Now the problem is that When I Checked toggle1 then toggle2 in order both cubes appears and when I Checked toggle2 then toggle1 then again both cubes appears....

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


public class ToggleToggle : MonoBehaviour {

    public Toggle toggle1;
    public Toggle toggle2;
    public GameObject cube;
    public GameObject cube2;

    // Use this for initialization
    void Start () {
        cube.SetActive (false);
        cube2.SetActive (false);
    }

    // Update is called once per frame
    void Update () {


        // Toggle1 Selected First then Toggle2
        if (toggle1.isOn && toggle2.isOn) {
            cube.SetActive (true);
        }

        // Toggle2 Selected First then Toggle1
        if (toggle2.isOn && toggle1.isOn) {
            cube2.SetActive (true);
        }
    }
}

If I understand well, you want to enable only one GameObject based on multiple Toggles. The first ticked determines which GameObject.

So you have to store the first ticked Toggle.

Here is an example :

public class ToggleToggle : MonoBehaviour {
/*
    public Toggle toggle1;
    public Toggle toggle2;
    public GameObject cube;
    public GameObject cube2;
*/

    public Toggle[] toggles;
    public GameObject[] cubes;

    public static Toggle firstTickedToggle;

    void Start ()
    {
        for (int i = 0; i < cubes.Length; i++)
        {
            cubes[i].SetActive(false);
        }
    }

    public void OnToggleClick(Toggle toggle)
    {
        if (toggle.enabled)
        {
            if (firstTickedToggle == null)
                firstTickedToggle = toggle;

            int toggleIndex = 0; // Index of the first clicked toggle

            // Check if all toggles are ticked
            for (int i = 0; i < toggles.Length; i++)
            {
                // If one is not ticked
                if (!toggles[i].enabled)
                    return;
                if (toggles[i] == firstTickedToggle)
                    toggleIndex = i;
            }

            // Here all toggles are ticked
            cubes[toggleIndex].SetActive(true);
        }


        else
        {
            for (int i = 0; i < toggles.Length; i++)
            {
                // If one toggle is still ticked, don't do anything
                if (toggles[i].enabled)
                    return;
            }

            // If all toggles are unticked, remove the reference to the first ticked
            firstTickedToggle = null;
        }
    }
}

All toggles need a OnValueChanged

The error in your program is you forget to notify the first button pressed:

public int first;
void Start () {
    cube.SetActive (false);
    cube2.SetActive (false);
    first = 0;
}

    // Update is called once per frame
void Update () {
    if (!toggle1.isOn && !toggle2.isOn) {
        first = 0;
    }

    if (first == 0 && toggle1.isOn) {
        first = 1;
    }        

    if (first == 0 && toggle2.isOn) {
        first = 2;
    } 

    if (first == 1 && toggle2.isOn) {
        cube.SetActive (true);
    }

    if (first == 2 && toggle1.isOn) {
        cube2.SetActive (true);
    }
}
