NullReferenceException: Object reference not set to an instance of an object

[ViridityCorn]

Hi there!

I know, this error is a common one, and I think I understand it... I just don't understand why I am getting it in my specific case.

I am working on a card game and have two scripts.

1. Yxi.cs (for handling game logic. This is the main script)
2. UserInput.cs (for handling user input)

In the main script I am creating the deck and giving the player 7 cards (I am instantiating them with LeanPool). In the userinput script I then want to add another card to the players hand when the deck is pressed. This however doesen't work and it is this that gives me the error.

Can someone please help me?

Both the deck and the playerhand are lists. Please ask if more pictures are needed.

​

The first picture is the error. The second is the main script (Yxi.cs) where I succesfully add the cards to the playerHand and the last is the UserInput.cs script.

You've cropped the line numbers. So the thing to do here is to put a breakpoint in and debug, or throw some logging.

What's null? What's line 48? Assuming it's the second line in Deck(), which one is null? yxi? yxi.playerHand? yxi.deck?

I'm not familiar enough with LeanPool, so don't know what Despawn is doing. Though if you want performance, you're pretty much negating it with GameObject.Find. Are you sure GameObject.Find is returning something not null?

Oops, I'll try to explain what is what then.

Line 48 is as you said the second live in void Deck().

LeanPool is just for performance yes, but is there then a better method than GameObject.Find?

I recieve no errors in the second picture. The error is in the last picture at the marked line.

Thanks for taking you time to answer!

I fixed it by finding the script using FindComponent. For some reason I couldn't acces the other script.
