How to change Texts in Unity 5 using UI Texts?

Questions & Answers
1

Hello,

I’m doing the Roll a Ball Tutorial in Unity 5. Until the “Displaying Text” part it went pretty well but i can’t find any solution to change the text displayed by UI Texts with a script… (As i’m very new to Unity i’d like to know how to make basic things like this work in Unity 5 and not using GUIText as it is said in the tutorial).

I dug a lot in the documentation, on the forums and on Unity answers but i never managed to do it.

In the inspector it says Text (Script) so i assumed it was a script and searched how to change script variables from other scripts, it didn’t helped a lot so…

Here are the things (highlighted in yellow) i’m trying to interact with:

here is my script (attached to the Player game object) as it is right now and i think that the only thing missing in it is the damn method i’ve been searching everywhere these last three days.

using UnityEngine;
using System.Collections;

public class characterController : MonoBehaviour {
	public float speed;
	public float sprint;
	private int count = 0;
	private string Text;
	public Component scriptText; 

	void Start(){
		count = 0;
		scriptText = GameObject.Find ("/Canvas/CountText").GetComponent ("Text (Script)");
		setCountText ();

	}
	void FixedUpdate(){

		float moveHorizontal = Input.GetAxis ("Horizontal");
		float moveVertical = Input.GetAxis ("Vertical");
		sprint = Input.GetAxis ("Sprint");
		Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
		if (sprint!=0) {
			speed = 1500;
			GetComponent<Rigidbody> ().AddForce (movement * speed * Time.deltaTime);
			speed = 500;
		}
		else{
			GetComponent<Rigidbody> ().AddForce (movement * speed * Time.deltaTime);
		}
	}

	void OnTriggerEnter(Collider other){
		if (other.gameObject.tag == "pickup") {
			other.gameObject.SetActive (false);
			count++;
			setCountText();
		}
	}
	void setCountText(){
		string counts = count.ToString ();
		Text = "Count: " + counts;
		// change the text in the UI script Text
	}

}

You need to store a reference to that Text component.

private Text txtRef;
private void Awake()
{
    txtRef = GetComponent<Text>();//or provide from somewhere else (e.g. if you want via find GameObject.Find("CountText").GetComponent<Text>();)
}
//then where you need:
txtRef.text = "text";

Or you can make it public/[SerializeField] and assign it by drag&drop in Inspector view.

public Text txtRef;
//or
[SerializeField]
private Text txtRef;
//and then the same thing - where you need it:
txtRef.text = "text";

Use at the top of the script:

using UnityEngine.UI;

Then write beside other publics:

Public Text test;

Then Where you want to change:

test.text = "YOUR TEXT";
