Game saving #126

Closed frnsys closed 2 years ago

frnsys commented 2 years ago

Just a simple save system in case e.g. someone closes the browser or something accidentally.

[x] At the end of each planning phase serialize the game state to local storage
[x] At new game/game over/game end, clear that local storage key
[x] On load, check if that local storage key has data; if so, resume game
[x] Requires that we can deserialize a JSON state back to Rust/Wasm
- [x] World
- [x] Industries
- [x] Projects
- [x] Processes
- [x] NPCs

So this is actually more complicated than I thought, since the engine was designed around one way serialization (we originally didn't intend to have game saves).

Possible workaround: use serde_json and define a Saveable trait that has a save method which returns a JSON value and a load method which takes a JSON value and modifies the struct's data accordingly.
