Last week, we talked about binary serialisation and we saw how to store info on our current game session in binary files. We focused on how to go from C# objects to binary-formattable data. Today, it’s time to do the reverse: we will implement our deserialisation process to load the data back and restore our previous state!

A note about the reload logic

Before we dive into the actual implementation, we just need to think for a while about execution order and dependencies.

The overall idea is obviously to:

• check the game current UID
• load the matching data file if it exists (or else ignore the load part and use the defaults)
• use this info to setup the various scene parameters
