A TickData describes one Tick (Block). It contains all important information a Computor needs to calculate the Tick.

To query the TickData, send a RequestedTickData Packet with the type set to 16.

Request Header

• Size: 12
• Type: 16
• DejaVu: any Random int

Request Payload

• unsigned int tick: The Tick for which you want to receive the TickData

Response Header

BROADCAST_FUTURE_TICK_DATA
