New UI: change text

Hey! I would like to change text on mouse pressed. I have a canvas and text parented to it. I’ve looked at API:

and wrote a simmiliar code, but it doesn’t work. In particular, in line: instruction.text = “this is text”; .text is highlighted red. Could you please help me? Thank you!

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

public class countscript : MonoBehaviour {

	public Text[] instruction;

	// Use this for initialization
	void Start () {
		instruction = GetComponentsInChildren<Text> ();	
	// Update is called once per frame
	void Update () {
		if (Input.GetButton ("Fire1")) {
			instruction.text = "this is text";

Your ‘instruction’ var is an array.
You probably want to use GetComponentInChildren instead of GetComponentsInChildren.

Since you have declared instruction as:

public Text[] instruction;

your instruction is an array of Text elements.

So you can access elements inside an array using an index like:

instruction[0].text = "this is text";

to access the first element in the array.

Or using a for loop:

for (int i = 0; i < instructions.Length; i++)
    instruction*.text = "this is text";*
