In this Game picture, you can see “Score : 22”. when start ‘play’, change into “Score : 0”
When I push the ‘s’ on keyboard, the Score must add ‘+5’ but still Zero.
Here is the script about it. ( 3 each )
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class UIManager : MonoBehaviour
{
public static UIManager Instance;
public Text scoreText;
void Awake()
{
Instance = this;
}
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
public void UpdateScore (int score)
{
scoreText.text = "Score : " + score;
}
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameManager : MonoBehaviour
{

public float scrollSpeed;
public float length;

// Use this for initialization
void Start ()
{
StartCoroutine (MoveBackground ());
}
// Update is called once per frame
void Update ()
{
}
IEnumerator MoveBackground()
{
Vector3 startPosition = backTransform.position;
moveOn = true;
while (moveOn)
{
float newPosition = Mathf.Repeat(Time.time * scrollSpeed, length);
backTransform.position = startPosition + Vector3.left * newPosition;
yield return null;
}
}

“Object reference not set to an instance of an object”
This message have been seeing.
I just typed the examples by studying.
But that error message is now shown.
Please help me.
