I haven’t implemented the death screen, scene transitions or respawn button as I just want the player to instantly respawn after death. The only issue is, upon death the animation plays and the player is just lying there infinitely. I’m not sure where the code isn’t linking.

I just checked my console and have this message if it helps at all. NullReferenceException: Object reference not set to an instance of an object. RespawnPoint.OnTriggerEnter2D (UnityEngine.Collider2D _other) (at Assets/Respawnpoint.cs:23)

The NullReferenceException you’re encountering indicates that your code is trying to access a variable or object that has not been initialized. This commonly happens when you try to use an object reference that is null.

To help you debug this, let’s take a look at a few common causes and how to resolve them:

1. Check the Line of Code: Look at line 23 of your Respawnpoint.cs script. Identify which object is being accessed at that line. It could be a variable that is supposed to be assigned in the Unity Inspector or in code but is currently null.

2. Inspect Your Variables: Ensure that all variables you are accessing on line 23 are properly initialized. This includes any GameObjects, components, or scripts you are trying to reference.

3. Trigger Logic: If you are using the OnTriggerEnter2D method, make sure the _other parameter is not null and that it is indeed the object you expect to collide with your respawn point. You might want to add a check for the tag or type of the object to ensure it is what you expect.

4. Setting Up in Unity: If you have public variables that need to be set in the Unity Inspector, make sure they are assigned to their respective objects in the Unity Editor.

5. Sample Debug Code: You can add some debug logs to see what exactly is null:

   void OnTriggerEnter2D(Collider2D _other)
   {
       if (_other == null)
       {
           Debug.LogError("_other is null");
           return;
       }
   
       // Example of accessing another component
       var player = _other.GetComponent();
       if (player == null)
       {
           Debug.LogError("Player component is null");
           return;
       }
   
       // Your logic here
   }

By following these steps, you should be able to pinpoint the cause of the NullReferenceException and fix it. If you can share the relevant part of your code, I may be able to provide more specific advice!

Can you share your RespawnPoint script? Let’s try and fix your NullReferenceException first and see if that resolves the rest of your issues.
