[1.18.2] how to check what item is on the ground

[tobywig]

im trying to make it so if an iron is hit by lightning it turns into a different item, but can't figure out how to actually detect what the ItemEntity is

[warjort]

ItemEntity.getItem()

[tobywig]

yeah but how do i check if that item for instance is an oak_boat?

also ItemEntity.getItem() gives me an error: the method getItem() is undefined for the type item

You really need to teach yourself how java works.

This is very basic stuff.  You need to be able to understand what the compiler is telling you.

You can't just post the error message here and expect others to fix it for you.

Especially when you don't even show the java code.

Anyway (untested pseudo code):

Entity entity = // from wherever
if (entity instanceof ItemEntity itemEntity) {
    ItemStack itemStack = itemEntity.getItem();
    if (itemStack.getItem() == Items.IRON_INGOT) {
        // Do stuff
    }
}

Usually it is better to define an item tag rather than hard wiring items in your code.

Also note an ItemEntity contains an ItemStack of items, not just 1 item.
