## Description Closes #296 - Redesigned the packet decoder to return packet _frames_ which are just the packet ID + data in raw form. - Made packet frame decoding happen in the client's tokio task. This has a few advantages: - Packet frame decoding (decompression + decryption + more) can happen in parallel. - Because packets are parsed as soon as they arrive, an accurate timestamp can be included with the packet. This enables us to implement client ping calculation accurately. - `PacketEvent`s are now sent in the event loop instead of a giant match on the serverbound packets. This is good because: - Packets can now be handled from completely decoupled systems by reading `PacketEvent` events. - The entire packet is available in binary form to users, so we don't need to worry about losing information when transforming packets to events. I.e. an escape hatch is always available. - The separate packet handlers can run in parallel thanks to bevy_ecs. - The inventory packet handler systems have been unified and moved completely to the inventory module. This also fixed some issues where certain inventory events could _only_ be handled one tick late. - Reorganized the client module and moved things into submodules. - The "default event handler" has been removed in favor of making clients a superset of `PlayerEntityBundle`. It is no longer necessary to insert `PlayerEntityBundle` when clients join. This does mean you can't insert other entity types on the client, but that design doesn't work for a variety of reasons. We will need an "entity visibility" system later anyway. ## Test Plan Steps: 1. Run examples and tests. |
