How to check what block the player is looking at?

[martiblq]

The version is 1.15. I want something to happen when the block the player is looking at is the same as whatever block. So it would be somethis like this

if(the block the player is looking at == Blocks.a block)

{

}

I just don't know how to check.

Entity#pick may be the method you want to use; it emits a ray that collides with blocks in the world. The first parameter is the range, the second is the "partial ticks" (you can just put a value of 1), and the third is if it should work on fluids.

The returned RayTraceResult will tell you what kind of thing it hit, as well as its position. From there, you can get the block at that position.

What are you even trying to do?

If you're trying to interact with a block you can just override onBlockActivated in your block class.

Read the vanilla code for the crafting table.

I want  to get an item in my inventory when i rightclick a specific block with a specigic item. I did the item part with an if in an event class. Can i put another if inside the first one that checks if the block is the right one?

If at least one of those is something you added raytracing is redundant.

If the block you're trying use is your own block, just override onBlockActivated as I mentioned and put in the code to check the item in your hand.

If the item you're using is your own item, override the item's onItemUse function.

If neither of them are your own, use the PlayerInteractEvent$RightClickBlock event.

Spoiler

if(event.getPlayer().getHeldItem(Hand.MAIN_HAND).getItem() == Items.NETHER_STAR)
        {
            
        }

this is the code for the held item. i can't just paste it in the block

Of course you can't,
