    public void StartTalking()
    {
        for (int i = 0; i < texts.Length; i++)
        {
            if (texts[i].text != "")
            {
                startTalking = true;
            }
        }
    }
}

I want that if one of the ui texts is not empty and not disabled to start talking by calling the StartTalking method. The game start when all the ui texts are disabled one of them is not empty but they are all disabled. And during the game they are turning disabled enabled in the game and get empty not empty. On the ui text is not empty.

The problem is in the Inspector I can't drag disabled ui texts to the array of the script.

All the ui texts are childs under their own parents that are childs of the prefab name Game UI Texts.

ui texts

This are the ui texts in the screenshot that should be dragged to the sccript on the right in the Inspector :

Scene Text , Description Text , and Long Distance Description Text

The main goal is to use one script to control automatic the talking with the text in the game. When there is a text in the game on the screen StartTalking and stop talking when there is no text on the screen.

  • \$\begingroup\$ First you need to change the 0 in blendshapescontroller script in the editor to 3. If you still can't drag and drop after that, you need to change the type of text to the one used by textmeshpro, which seems to be TextMeshPro \$\endgroup\$

If your current Text[] is still 0 as in the screenshot, you need to first increase the size of it to the amount you want to drag -> 3. You can drag them regardless if they are enabled or not.

Now you should be able to drag each of the texts into the text array. There is no need to change the type of the Array to a GameObject Array, Unity is able to find the matching component as long as there is only one Text component on the dragged GameObject.

\$\begingroup\$

The array is of type Text, which is the type of a component, but you're trying to drag an object which contains the Text component, which is of type GameObject. Make your array of type GameObject[] and then use GetComponent or GetComponentsInChildren on the stored objects to get to the text itself.

EDIT: given the new info, I've included the import and type of the array you need:

using TMPro;

and then define the array as:

public TextMeshProUGUI[] texts;

  • \$\begingroup\$ @ShamenRaze Ah, in that case, you can add the import, and then the type for it is TextMeshProUGUI. I'll update my answer so you can see the code properly \$\endgroup\$ Dec 31 '20 at 5:15
