Unity Transport for Netcode for GameObjects

Added

  • Support for Unity Relay (#887)
  • New SetConnectionData function that takes in a NetworkEndpoint

Changed

  • No longer use coroutines when connecting to relay
  • Consolidated the Send/Recv queue properties as they always needed to be the same.
  • Consolidated the Fragmentation/Queue size as they always needed to be the same.
  • Updated Unity Transport package to 1.0.0-pre.6

Fixed

  • Possible Editor crash when trying to read a batched packet where the size of the packet was larger than the max packet size.
  • Removed the requirement that MaxPacketSize needs to be the same size as the batched/fragmentation buffer size.
