FindGameobjectsWithTag -> get values from toggles and sliders

Unity Engine
1

Hi
I am getting a group of gameobjects and need to get the values the user sets for sliders and toggles.

I haven’t got very far and need some help if possible, please!

 var objects = GameObject.FindGameObjectsWithTag("formfield");
        Debug.LogWarning("how many? " + objects.Length);

        foreach (var obj5 in objects)
        {
                  Debug.Log("object name:" + obj5.name);    //this works a treat
            //   int valueBool = Convert.ToInt32(obj5.isOn); //this doesn't. How do i get the value of the toggle or slider.  
            
        }

I have done numerous searches and can’t find anything; but think that is probably because I don’t know how to encapsulate this question in a search!

Since you need the sliders and toggles, find the sliders and toggle instead of the GameObjects… Sincerely not sure which of these would have a better performance but you could:

        var selectables = GameObject.FindObjectsOfType<Selectable>();      
        for(int i = 0; i < selectables.Length; i++)
        {
            if(selectables[i] is Toggle)
            {
                  (selectables[i] as Toggle).//Your action
                  return;
            }
            if(selectables[i] is Slider)
            {
                  (selectables[i] as Slider).//Your action
            }         
        }

        var toggles = GameObject.FindObjectsOfType<Toggle>();      
        var sliders = GameObject.FindObjectsOfType<Slider>();      

        for(int i = 0; i < toggles.Length; i++)
        {
        }
        for(int i = 0; i < sliders.Length; i++)
        {
        }

Anyway, if it’s posibble to have the sliders serialized or stored at any variable at runtime without using FindObject methods it would be better.

I won’t know what they are as have multiple scenes with different numbers of sliders and toggles. If I serialise won’t I have to hard code? My aim is to do this dynamically as different scenes have different make up of sliders and toggles and don’t want a script for each scene

Will try your solution - thanks very much for helping me out

tried to implement but still don’t understand how i get the value of the slider or the toggle!
sorry to be a pain but can you explain?
thanks

Both of the API references for those show the values, I suggest you read the API reference for this sort of queries.

there is a “value” field.

yes but it isn;t available - that is why i posted this question. I can’t access isOn or value for toggle and slider respectively

ok so I have made a bit of progress

foreach (var obj5 in toggles)
        {
            Debug.Log("is it on" + obj5.isOn);
        }
        foreach (var obj6 in sliders)
        {
            Debug.Log("is it on" + obj6.value);
        }

but that gives me the minimum value of the slider, not the amount it is set to

using update() seems to be a workaround but doesn’t feel very efficient!

ok so to wrap up this post, this is what I ended up with

To get values from DB and populate scene:

//get the results ffrom your db and return it to the c# script

            string json = wwwa.downloadHandler.text;
            UserHabits loadedPlayerData = JsonUtility.FromJson<UserHabits>(json);
            var toggles = GameObject.FindObjectsOfType<Toggle>();
            var sliders = GameObject.FindObjectsOfType<Slider>();
            Debug.Log("111. record count: " + loadedPlayerData.data.Count);

            //sliders
            foreach (var sliderIs in sliders)
            {
                var slidervalue = sliderIs.value;
                  var nameofslider = sliderIs.name;
                int numbernameofslider = Convert.ToInt32(nameofslider);

                for (int i = 0; i < loadedPlayerData.data.Count; i++)
                {
                   
                    if (loadedPlayerData.data[i].Habit_ID == numbernameofslider)
                    {
                       sliderIs.value = loadedPlayerData.data[i].amount;
                    }
                }
            }

//then get the values from the scene and write back to DB: 
 var toggles2 = GameObject.FindObjectsOfType<Toggle>();
        var sliders2 = GameObject.FindObjectsOfType<Slider>();

        //get the values of each slider
        //get the label for each slider
        //set the obj to loop until count is finished
        //set the the global variable for next scene
         UserHabitsPut obj = new UserHabitsPut();
           foreach (var sliderIs2 in sliders2)
        {
            var habitValue = sliderIs2.value;
            habitValue_U = Convert.ToInt32(habitValue);
            var habitID = sliderIs2.name;
            habitID_U = Convert.ToInt32(habitID);
        

            //add to JSON
            obj.data1.Add(new habitinfoput()
            {
                Habit_ID = habitID_U,
                amount = habitValue_U,
                label = "slider"
            });
           
        }

This required me to change the names of the form controls to correspond to the DB ID. I imagine there is a way to assign a variable to the object so this isn’t necessary… but I couldn’t find how!
