Making the player's launcher crash

How would one go abouts making a player's client launcher crash (and display some java error) intentionally? I need this because I plan on having the player's client crash if he says a certain word.

 

@Neilnet There are plenty of ways. Personally I have always sent a blockcrack particle packet with an invalid id, but its up to you.

 

Amazing, I just looked up sending packets. It's like this:

1. ((CraftPlayer)player).getHandle().playerConnection.sendPacket(packet);

I've worked with packets before in my own networking programs, but how would I send a blockcrack particle packet?

Or is it just like this:
player.getLocation().getWorld().playEffect(player.getLocation(), Effect.STEP_SOUND, ID) ?

 

@Neilnet Look at the list of particle effects on the wiki and PacketPlayOutWorldParticles constructor.

 

Create an inventory that doesn't exist and force the player to open it. Simple way of doing it in about 2 lines of code

 

Player player = e.getPlayer();
Inventory inv = null;
player.openInventory(inv);

Gives a console error, doesn't work. NPE.

 

@Neilnet Use packets.

 

Don't make it null. Make it non-existent using an integer that is not a multiple of 9 or that is superior to 99(Not sure what the highest # of inventory slots are).

Inventory inv = Bukkit.createInventory(player, 999);

 

e.setCancelled(true);
Player player = e.getPlayer();
PacketPlayOutWorldParticles asd = new PacketPlayOutWorldParticles();
((CraftPlayer)player).getHandle().playerConnection.sendPacket(asd);

Works, but it doesn't crash to the launcher.

 

@Neilnet Send a blockcrack effect with an invalid id.

 

@Skionz
The constructor is PacketPlayOutBlockChange(int i, int j, int k, World world),
I really am clueless as to what i, j and k are.

 

@Neilnet Gotta love packets for that!

 

@Neilnet I never said anything about the PacketPlayOutBlockChange class.

 

Inventory inv = Bukkit.createInventory(player, 999);
player.openInventory(inv);


@Neilnet

 

@Vamure
Doesn't work, just creates an inventory that overlaps in the latest version.


@Skionz
Could you show me an example please?

 

@Neilnet Ive told you how... Just create a PacketPlayOutWorldParticles instance with an invalid blockcrack id.

 

PacketPlayOutWorldParticles asd = new PacketPlayOutWorldParticles();

Doesn't let me add arguments of any kind.

 

@Neilnet The class has multiple constructors.

 

(String name, float x, float y, float z, float xOffset, float yOffset, float zOffset, int amount, int data)

 

Code:

public PacketPlayOutWorldParticles(EnumParticle paramEnumParticle, boolean paramBoolean, float paramFloat1, float paramFloat2, float paramFloat3, float paramFloat4, float paramFloat5, float paramFloat6, float paramFloat7, int paramInt, int[] paramArrayOfInt)

 

Locked.
