[1.15.2] Unable to compare RegistryObject<Item> to Item


Recommended Posts

Posted

I'm trying to model an item after the book and quill. The goal is to open a GUI in which the player can write stuff, and when a button is pressed use NBT to store it. To make things easier on myself I'm limiting it to one page and no signing feature. 

In the packet handler, I'm creating a method (called processEditScroll, obviously a copy of processEditBook from ServerPlayNetHandler) that checks if the item in hand is the scroll (again, like processEditBook). What I believe to be the relevant code is here:

public void processEditScroll(ScrollPacket packetIn) {

    ItemStack itemstack = packetIn.getStack();
    if (!itemstack.isEmpty()) {
        if (MessageScrollItem.isNBTValid(itemstack.getTag())) {
            ItemStack itemstack1 = this.player.getHeldItem(packetIn.getHand());
            if (itemstack.getItem() == ModItems.MESSAGE_SCROLL)

I'm aware I can't compare ItemStacks to Items (since I did try and look into it before posting, and that's the only related problem that pops up) so I use itemstack.getItem. The issue I'm having is that Intellij says 

Quote

Operator '==' cannot be applied to 'net.minecraft.item.Item', 'net.minecraftforge.fml.RegistryObject<net.minecraft.item.Item>

In case it's at all relevant, I'm using the DefferedRegistry system.

Have you tried ModItems.MESSAGE_SCROLL.get()?
The method comment for RegistryObject::get is:

Quote

/**

* Directly retrieves the wrapped Registry Object. This value will automatically be updated when the backing registry is updated.

* Will throw NPE if the value is null, use isPresent to check first. Or use any of the other guarded functions.

*/
