You want to override the tell command, that has also the w and msg aliases by default. The class that will override these commands is MyTellCommand (extends PluginCommand).

To do this, you've to set the original command in a state that allows it to be overriden. Also, aliases will be registered directly, but since all the work was done for the first registration, it's pretty simple.

//We are in the context of a plugin

MovePlayerPacket sends weird yaw values

• Step 1: Rotate the head in one direction multiple times
• Step 2: Get MovePlayerPacket with yaw > 360, example: 6407.0166015625
• This can cause rounding errors after too many rotations

NULL UpdateBlockPacket is sent by the client randomly

• Step 1: ??? (happens in vanilla and PocketMine)
• Step 2: Get an UpdateBlockPacket with x, y, z, blockId, blockData all 0 (null)
• This packet is not meant to be sent by clients, it's only Server -> Client
