Hello!
Very new to unity and have run into null reference exception: object reference not set to instance of an object.
I have just been following a tutorial and cannot seem to get this to work. Below I have attached the code and image file below!
Thank you!
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class ColorController : MonoBehaviour
{
public Material[] wallMaterial;
Renderer rend;
// Appears in the Inspector view from where you can assign the textbox
public Text displayText;
// Start is called before the first frame update
void Start()
{
// Assigns the component's renderer instance
rend = GetComponent<Renderer>();
rend.enabled = true;
displayText.text = "";
}
// Called when the ball collides with the wall
private void OnCollisionEnter(Collision col)
{
// Checks if the player ball has collided with the wall.
if (col.gameObject.name == "player-ball")
{
displayText.text = "Ouch!";
rend.sharedMaterial = wallMaterial[0];
}
}
// It is called when the ball moves away from the wall
private void OnCollisionExit(Collision col)
{
if (col.gameObject.name == "player-ball")
{
rend.sharedMaterial = wallMaterial[1];
displayText.text = "Keep Rolling...";
}
}
}
