Problem by collision with OnCollisionEnter2D class

Question

Hey, I have problem with a simple spike script. I have attached the following script to the spike.

View it works also. The spikes are used in a jump down game. After the player has already jumped down several platforms the script is resolved even if the player does not touch the spikes.

 public class CollisionSpikes : MonoBehaviour
 {
     private void OnCollisionEnter2D(Collision2D other)
     {
         SceneManager.LoadScene(0);
     }
 }

Here is a picture of how the spikes and their BoxCollider2D are connected to each other. alt text I first suspected when all colliders touched each other that this would lead to this error. But the problem still occurred. Here is a video so you can get an impression of the error: https://www.youtube.com/watch?v=IouGpT0AwjI

Does anyone here have an idea how I can fix this problem? I am relatively new to Unity and C# and unfortunately I am stuck here.

Thanks for your help. :)

I have found the solution.

I forgot to query which object touches the collider. I have now changed this and now it works.

 private void OnCollisionEnter2D(Collision2D playerCollision)
     {
         if (playerCollision.gameObject.tag == "Player")
         {
             SceneManager.LoadScene(0);
         }
     }
