Gui text

Greg DAlessandro · Apr 2015

Does anyone know how to solve this problem?

Assets/Scripts/CoinCounter.cs(12,25): error CS0120: An object reference is required to access non-static member `UnityEngine.GUIText.text'

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

public class CoinCounter : MonoBehaviour 
{
	public int coinCount = 0;
	
	// Update is called once per frame
	void Update () 
	{
		GUIText.text = "x" + coinCount;
	}
}

I can't figure out why it is giving me this error.

GUItext is just a class. You need to make an instance of the class before setting it's text.

GUIText myText;
myText.text = "my text here";

Or it might be a mono behaviour so you'll have to add a GUIText component to your object and get a reference to it.

Text is working, but there is a new issue:

NullReferenceException: Object reference not set to an instance of an object
CoinCounter.Update () (at Assets/Scripts/CoinCounter.cs:12)

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

public class CoinCounter : MonoBehaviour
{
    public int coinCount = 0;
    Text text;
    // Update is called once per frame
    void Update ()
    {
        text.text = "x" + coinCount;
    }
}

You are declaring your Text as a variable. But in C# variables are set to private by default. And you are not putting anything in, so it can't find anything in there and throws a NullReferenceException.

What you could do is put public in front of your variable so it becomes visible in the inspector. Then just drag your UI text into it.
