Open:
|
||||
- Rework State implementation for easier cloning/deserialization
|
||||
- Insecured websocket server implementation
|
||||
- Refactor input messages for more than one player
|
||||
- Insecured websocket server implementation
|
||||
- Cloneable RNG that goes in state (use MurmurHash3 finalizer in counter mode?)
|
||||
- remove all random() calls
|
||||
|
||||
Done:
|
||||
- Rework State implementation for easier cloning/deserialization
|
||||
- Test Lockstep/rollback
|
||||
- Smarter typings for Join/Lookup functions
|
||||
- Parcel scripts
