An array isnt being duplicated when using the duplicate(true) func

Question

Here is a video link to my problem that I have uploaded to youtube: https://www.youtube.com/watch?v=_8Pa_wz4bfk

    if dropable:
    if Input.is_action_just_pressed("right_click"): 
        if inventory[dropable_index] != null: # If input and slot isnt empty add and remove 1
            if inventory[dropable_index].amount < inventory[dropable_index].max_amount:
                if hand_array[0].amount > 1:
                    inventory[dropable_index].amount += 1
                    hand_array[0].amount -= 1
                    update_slot(dropable_index)
                    update_held_item()
        else:
            if hand_array[0].amount > 1:
                var saved = hand_array.duplicate(true) # A dup that SHOULDNT TOUCH THE ORIGNAL ARRAY
                saved[0].amount = 1 # sets it to one ONCE
                print(hand_array[0].amount) # GETS TOUCHED ANYWAY
                inventory[dropable_index] = saved[0] # Setting the new inventory slot to new item
                hand_array[0].amount -= 1 # Removes one to make it look like its dropping a item
                update_slot(dropable_index)
                update_held_item()

for what ever reason this website cant format my code correctly...

anyways I am trying to duplicate an item in the array between two different arrays one being the inventory and one being the held item array but for what ever reason it keeps touching the held item array when I SPECIFICALLY TOLD IT, ITS A DUPLICATE and it still touches the array like its still referencing it when i told it, it shouldn't!

Answer 1

I can't see any problem with your code. But I had an idea: maybe your handarray is referencing some object that is pending an update on the next frame? If that is a cause of the problem then calldeferred may be a solution. Calling the update code later.

Actually figured it out with some help from Reddit, the issue is that the data stored is a custom class that doesn't get stored but referenced which is why this happens.

Thanks for the comment though!
