Solved PacketPlayOutSpawnEntity

I am currently playing around with PacketPlayOutSpawnEntity. However in game the block above my head is stone when I need it to be a diamond block. I am not sure if i am setting the "k" value correctly? Am I missing something or am I doing something wrong?

Any help would be appreaciated.

protip:

open gravel and sand blocks source code and check how they spawn fallingblock.

you will instantly get answer.

 

I will instantly get an answer? What am I looking for?

 

I reread the wiki.vg/protocol article on your packet again, and it seems that it is not the one you would want. I would instead recommend this one:

http://wiki.vg/Protocol#Spawn_Object

Comphenix is usually a god with packets. He could probably give you more help with this than I could ever.

 

It's the same packet. I know what I'm doing when it comes to packets, it's just debugging I'm not too sure about

 

Ah, I see - you're not actually spawning a falling block (like a sand entity) - you're spawning an item stack entity.

In that case, try setting the item material using an ENTITY_METADATA packet (here using ProtocolLib + PacketWrapper):

Code:java

public class ExampleMod extends JavaPlugin {
    private int entityId = Short.MAX_VALUE;
 
    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (sender instanceof Player) {
            Player p = (Player) sender;
            spawnFloatingItemStack(p, new ItemStack(Material.DIAMOND, 1));
        }
        return true;
    }
 
    private void spawnFloatingItemStack(Player p, ItemStack stack) {
        WrapperPlayServerSpawnEntity block = new WrapperPlayServerSpawnEntity();       
        block.setEntityID(entityId++);
        block.setX(p.getLocation().getX());
        block.setY(p.getLocation().getY());
        block.setZ(p.getLocation().getZ());
        block.setType(2);
        block.sendPacket(p);
 
        WrapperPlayServerEntityMetadata metadata = new WrapperPlayServerEntityMetadata();
        metadata.setEntityId(block.getEntityID());
        metadata.setEntityMetadata(
            Arrays.asList(new WrappedWatchableObject(10, stack))
        );
        metadata.sendPacket(p);
    }
}

 

Thank you! I will try this when I get back from school
