trying to delete a gameobject after a different gameobject collision - c# unity difficulty in regard to a function for destroying all items with a tag

Question

i am trying to make a game and this includes a fence that the player can only go through once they located the key. the fence is a trigger so can be walk through but there is an object behind acting as the barrier. i am trying so that if the player has the key and collides with the fence, the barrier will disappear on all fences.

i am getting the errors "Assets\playerController.cs(18,17): error CS1002: ; expected" and "Assets\playerController.cs(18,30): error CS1519: Invalid token ';' in class, record, struct, or interface member declaration" ,but if i add the semi colon it still gives me the "Assets\playerController.cs(16,28): error CS1519: Invalid token ';' in class, record, struct, or interface member declaration" error.

Answer 1

The line after

public List<string> items;

You wrote

public GameObject[];

All fields must have their own names, like 'items', this line you declared a field without a name.
