So I want to add a gameObject to a list when the collider triggers. So I add other.gameObject to get the gameObject of the collider. But then it says that other.gameObject is of type UnityEngine.GameObject and my list is containing the type GameObject. What is the difference?

     List<GameObject> possibleItemsToPickup = new List<GameObject>();   
     if (other.gameObject.CompareTag("Item"))
     {
        possibleItemsToPickup.Add(other.gameObject);
        Debug.Log("added Item");
     }

This is just extracts of the code.

The problem is that you have defined your own class named “GameObject”. You should avoid using the same class / fie names as Unity uses for it’s built-in classes.

If you still want to do this, you have to specify the full class name everytime you want to use the GameObject class of Unity:

List<UnityEngine.GameObject> possibleItemsToPickup = new List<UnityEngine.GameObject>();
