Resolved [2D Top Down Game] Trying to make the tree & bush sprites fade when the player is behind it

Errors: NullReferenceException: Object reference not set to an instance of an object
PlayerMovement.OnTriggerEnter2D (UnityEngine.Collider2D collision) (at Assets/Player/PlayerScripts/PlayerMovement.cs:77)
NullReferenceException: Object reference not set to an instance of an object PlayerMovement.OnTriggerExit2D (UnityEngine.Collider2D collision) (at Assets/Player/PlayerScripts/PlayerMovement.cs:86)

Player Script:

Code (CSharp):

1. private void OnTriggerEnter2D(Collider2D collision)
2.     {
3.         if (collision.tag == "Environment")
4.         {
5.             EnvironmentTransparent Script = collision.GetComponent<EnvironmentTransparent>();
6.             Debug.Log("Bruh");
7.             Script.FadeOut();
8.         }
9.     }
10.  
11.     private void OnTriggerExit2D(Collider2D collision)
12.     {
13.         if (collision.tag == "Environment")
14.         {
15.             EnvironmentTransparent Script = collision.GetComponent<EnvironmentTransparent>();
16.             Script.FadeIn();
17.         }
18.     }

Sprite fade script:

Code (CSharp):

1. public class EnvironmentTransparent : MonoBehaviour
2. {
3.  
4.     public SpriteRenderer sprite;
5.     private Color defaultcolor;
6.     private Color fadedcolor;
7.  
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.         sprite = GetComponent<SpriteRenderer>();
12.  
13.         defaultcolor = sprite.color;
14.         fadedcolor = defaultcolor;
15.         fadedcolor.a = 0.7f;
16.     }
17.    
18.     public void FadeIn()
19.     {
20.         sprite.color = defaultcolor;
21.     }
22.  
23.     public void FadeOut()
24.     {
25.         sprite.color = fadedcolor;
26.     }
27. }
28.
