Pixel Tennis Changelog

Post by WongKit »

:idea: This topic serves as a kind of public changelog.

There was much more text here with me rambling about stuff that was not finished and that everything was work-in-progress. Well, several years later, I finally can get rid of it :D

Database
Verified a way to use the forum account credentials to log into the gameserver.

Networking P2P
Revised player state synchronization to reduce delays on the local client.

Gameplay
Score system implemented which determines points for the certain player. The score is currently handled internally and not visible as there is no UI. Fixed serve-ball-hit-ground-target-position

Network Gameserver
Complete network communication protocol rewritten. All changes lead to a 4x performance increase at about 1/10th of data usage!

The old logic worked still good enough for the game server, but...

Networking P2P
... Pixel Tennis multiplayer will switch from UNet peer to peer to a semi authoritative server. This means, that the server needs to process a lot more data making the mentioned network optimizations mandatory. You can read the reason for the switch here.

Networking P2P
Starting to develop custom replacement methods for UNet's build in functions. This includes, object spawn handling, message handling on object base and smooth player position synchronization across a match hosted on the semi authoritative server.

Although, this does not have any visual effect, it requires a lot work and refactoring (more than 500 lines of code added/changed in the past 2 weeks). Thanks Unity's UNET deprecation...

Networking P2P Gameplay
Switch from UNet peer to peer to a custom network implementation is mostly done. Pixel Tennis' match networking logic will now run through a dedicated server located in Germany.

Pros:
- Increased network compatibility as no direct connection (port forwarding + firewall madness) is required anymore
- Better protection against client manipulation
- Restored compatibility to future Unity Engine versions

Cons:
- Increased server load
- Players connecting far away from the server location will experience higher pings as before. However, additional dedicated servers at different countries can be established later if required.

I learned very much about message handling, serialization and networking in general. Although this task required so much work and did not bring new features, it was still a very important step towards Pixel Tennis' future.

Added exp and level distribution after match.

Network Gameserver
Prevent multiple logins with the same account.
Fixed chat messages in a room not reaching the first player
Added logic for sending/managing private messages between characters*

Menu Navigation / UI
Implemented nested prefabs to greatly improve UI structuring as Unity finally supports it in their LTS releases.
UI handling and instantiation rewritten based on a best practices menu system design. In numbers: These UI changes took about 20 hours to complete and resulted into a change of about 30k lines of (mostly generated) source files.
Remember logged in username between sessions
Fixed some UI elements being invisible on certain screen/window resolutions


Again, a big thanks @BoneD for helping out on the gameserver side!
