Update text component¶

In this section we are going to programmatically add / change text.

First, under Hierarchy window we are going right click and select Create Empty game object, call it Game.

Best practice is also to reset it's coordinates to (0;0;0). Then, while in the Inspector window, we can click on Add component -> New Script and name it AdventureGame, open it in Visual Studio.

We are going to use UI namespace and add text component.

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


public class AdventureGame : MonoBehaviour
{

    [SerializeField] Text textComponent;

    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }
}

By using the [SerializeField], it will add the field to our inspector.

Then, we can click on the little circle icon and select an element we want to reference. We select Story Text (text) element.

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


public class AdventureGame : MonoBehaviour
{

    [SerializeField] Text textComponent;

    // Start is called before the first frame update
    void Start()
    {
        textComponent.text = "Hello World!";
    }

    // Update is called once per frame
    void Update()
    {

    }
}

Now, when we run the game, the text changes:
