Questions & Answers

Hi. I want to use GUI Text to display a score, but it needs to change. Can I please have a basic code snippet to change the displayed text from a variable?

Thanks!

Check out the docs for GUI Text. You'll specifically be interested in the text variable of a GUI Text.

First put using UnityEngine.UI; then do the following and attach this script to UI TEXT Control.

     using UnityEngine;

     using UnityEngine.UI;

      using System.Collections;

     public class DisplayScore : MonoBehaviour {

 Text txt;
 private int currentscore=0;

 // Use this for initialization
 void Start () {
     txt = gameObject.GetComponent<Text>(); 
     txt.text="Score : " + currentscore;
 }
 
 // Update is called once per frame
 void Update () {
     txt.text="Score : " + currentscore;  
     currentscore = PlayerPrefs.GetInt("TOTALSCORE"); 
     PlayerPrefs.SetInt("SHOWSTARTSCORE",currentscore); 
 }

}

Like Elliot said:

guiText.text = "New Text";

You didn't tell us what language you use, but fortunately this line is the same in JS or C# (i guess you don't use Boo? right?) ;)

edit

To change the GUIText of another GameObject you can put a public variable at the top of your script and drag the desired GameObject/GUIText onto the variable in the inspector.

// JS
var targetGuiText : GUIText;

function Start()
{
    targetGuiText.text = "Hey ya!";
}

To find the GUIText object, you can also use GameObject.Find, like so:

guiText = GameObject.Find("GUI_TEXT_NAME").guiText;

For effieciency, do this in the Start() function and save it to a private GUIText variable.

As of Unity 2.0, you can also use the GUI.Label function.

Here what I used. I tried a few other methods that gave me some issues, this seems to work great with the yourText GUI Text Object dragged into the inspector:

public class WhateverScript : MonoBehaviour {

	public GUIText yourText;

void Update (){

	yourText.text = "Coins " + currentCoins + "/" + maxCoins;

The old UI has been decomissioned.

However is does not show how to assign dynamically value to the text only explains how to use Richtext editor.

As said by gregolio, there is a new UI system.
