Different TickComponents

There are multiple TickComponents in different contexts, each with a slightly different purpose:

• GameState: This is the primary TickComponent which every other component refers to. It describes the actual Tick of the simulation (you can also say Frame-number) and gets incremented on every Tick

• Input: Whenever you want to execute a command, you have to specify at which tick it should be executed on

• Snapshot: A 'lookup' to find for which tick a snapshot exists (for example: if a rollback for tick 50 is requested, it will look for which ticks a snapshot exists. If a snapshot was created in tick 42, then the simulation will rollback to tick 42 and fast-forward to tick 50)

• Game: There is no direct TickComponent in the game-context. However, the backup-component stores a reference to a tick. The reference indicates for which tick the backup was created (same as snapshot)
