Detect which block an item stack is touching

[Strahlend]

I want to be able to detect if an item stack is touching a block and which block its touching when the player drops it. I am overloading the dropped by player event on this item. How can I get what the stack is touching / if its falling? Thanks!

Edit: I am using Forge Version 1.18.2

You can override IForgeItem.onEntityItemUpdate()

This is called from the ItemEntity.tick() method for your Item.

Within that same method you can see it doing position based checks like if it is water or closer to your requirements, getting the friction of the block beneath the item.

Your answer showed me that I had a bit more to learn but I was able to figure it out! Here is the finished result. Thank you! 

 

@Override
    public boolean onEntityItemUpdate(ItemStack stack, ItemEntity entity) {
        if (entity.isOnGround()) {
            entity.level.explode(entity, entity.getX(), entity.getY(0.0625D), entity.getZ(), 4.0F, Explosion.BlockInteraction.BREAK);
            entity.kill();
        }
        return super.onEntityItemUpdate(stack, entity);
    }

You made a hand grenade. 🙂

 

That method is called on both the client and the server.

You should really only be creating explosions on the server, check the entity.level.isClientSide

Lol yes! Thank you for the tip! I am looking into making an exploding arrow next and noticed that abstract arrows are only created server side as well. I have a lot to learn. 😵
