## Breaking Changes
Incoming packet registration signature has changed to:
```cs
delegate* void OnReceiveCallback(NetState state, SpanReader reader, int packetLength);
IncomingPackets.Register(int packetID, int length, bool ingame, OnReceiveCallback onReceive);
```
For example, an incoming packet handler signature would now look like this:
```cs
public static void SomeIncomingPacket(NetState state, SpanReader reader, int packetLength)
{
// Parse the data
}
```
## Summary
Updates the network Pipe class to use a mirrored memory technique. This technique involves mapping the same physical memory to two contiguous virtual memory spaces so the byte buffer appears duplicated. This allows writing to a double-sized array to wrap around without the need for the `CircularBuffer` classes.
In practice this allows us to use `Span<byte>` as if the buffer was a regular array.
### Bug Fixes
- [X] Fixes bad fixed length string parsing
### Summary
- Removes Fastwalk system
- Removed the following settings:
- `movement.enableFastWalkPrevention`
- `movement.fastwalkExemptionLevel`
- Adds movement throttle system.
- Adds the following settings:
- `movement.throttleReset` - Default value is `1000` (1 second).
- `movement.throttleThreshold` - Default value is `400` (400ms).
### Movement Throttling
This new system will trigger if a player requests 400ms (configurable) worth of movements quicker than wall clock time. When this happens, the player is throttled (all incoming packets to the server are halted) until wall clock time catches up with the requests. Upon each throttle, the player receives enough credit to handle up to 400ms of "lag" as a grace/catch-up.
### Developer Notes
We use two throttle queues to prevent an infinite loop.
- [X] Fixes several bugs
- [X] Updates more ordinal issues
- [X] Cleans up the code a bit
- [X] Turns classes static that should have been
- [X] Changes TcpServer.Instances to a HashSet
