My Slider GameObject has a GUIText child. I am writing a C# script that should change the text component in the GUIText, but instead of this I am getting:

error CS1061: Type UnityEngine.GUIText[]' does not contain a definition fortext' and no extension method text' of typeUnityEngine.GUIText[]' could be found (are you missing a using directive or an assembly reference?)

 public Slider timeSlider;
 int i = 5;

 timeSlider.GetComponentsInChildren<GUIText>().text = 'Some Text' + i;
 //timeSlider.transform.GetComponentsInChildren<GUIText>().text = 'Some Text' + i; // doesn't work either

From the documentation I understand that GUIText should have a 'text' variable - Would anyone know why ().text is invalid?

Thank you!

How the hierachy is:

You are using GetComponentsInChildren, which as the error message tells you, returns an array of Unity.GUIText objects. That array doesn't have a text property. So you will probably want to iterate over the objects returned or use a different method for accessing the component(s).

  • \$\begingroup\$ Good point. I just tried with timeSlider.GetComponentInChildren<GUIText>().text= "Some Text"; and get a NullReferenceException... would you have a suggestion for accessing the GUIText component (exact hierarchy in question)? \$\endgroup\$

Script needs to run on the parent. Then use this:

  transform.FindChild("child name").GetComponent<GUIText>().text = "some Text";

Now why would you use GUIText and not just Text that is part of the new UI system is beyond me.
