Update Server-Client Example to Support Latest Mirror Framework

[shiva30122]

Hi PlayFab team,

I’ve been trying to integrate the latest version of the Mirror framework (v96.0.1, as of April 2025) with the server-client example project in this repository ( the MpsSamples/UnityMirror/ ), but I’m running into multiple errors. It seems the example hasn’t been updated in over 3 years (since around 2021-2022), and it’s incompatible with the current Mirror version due to outdated dependencies and APIs.

Mirror has evolved significantly since then—adding client prediction, better performance, and Unity 6 support—making it a powerful choice for multiplayer games in 2025. However, the lack of updates here makes integration a headache, especially for devs like me aiming to scale projects (e.g., targeting 1M+ monthly active users).

Could you please update the server-client example to work seamlessly with the latest Mirror framework? This would help the community leverage PlayFab’s multiplayer servers with modern tools. Alternatively, a new sample or updated documentation pointing to a working setup would be awesome.

Thanks for your time and support! Let me know if I can assist with testing or details.

Best,

thanks for the report @shiva30122
I'd be more than happy to take a look at upgrading the sample, but unfortunately I haven't played with Mirror since, well, I did the existing sample so I'd love any help! I can start looking soon but if you're aware of any upgrade guide or anything whatsoever that can help us accelerate this work, please share.

Hi @dgkanatsios,

Thank you for your response! I’m finding the PlayFab server deployment process quite challenging. My company uses Azure as our backend, and they’ve asked me to explore PlayFab servers for this project. Unfortunately, I keep encountering issues where deployments go to an unhealthy state. The lack of clear video tutorials or updated guides for uploading new servers makes it even tougher.

I’m also unsure if there are logs available on the server-side VM to help debug these issues. For instance, with Azure Functions, I can easily view incoming player data and processing details in the logs, but I’m not sure how to access similar logs for PlayFab’s server VM to pinpoint what’s going wrong. Are there logs on the VM, and if so, how can I check them?

If you’re updating the sample, I believe just providing server build code might not be sufficient.

Many developers like me would greatly benefit from visual references, such as video tutorials or detailed walkthroughs. Documentation alone often makes it harder for developers to adopt.

I’m happy to continue testing on my end, but could you provide guidance on accessing and debugging server logs on the PlayFab server , along with any debugging tips? For context, I’m working on a simple multiplayer setup with authentication (using player name or ID) and a feature that prints “hello world” + the player’s ID or name for all connected players when someone joins. I’ve built a local multiplayer game before, so I’m familiar with server-client communication, RPCs, and client-server data processing. For this project, I updated the existing PlayFab authentication sample project with the Mirror package to include this logic (with some ChatGPT assistance to implement the authentication and print functionality). Locally, it runs Logic , but I’m running into issues with the line private const string GsdkConfigFileEnvVarKey = "GSDK_CONFIG_FILE";. I’m unsure what this variable should contain. If I don’t comment it out ( // ) locally, my server.exe quits, but I uncomment ( // ) it when building the server to push to PlayFab. On PlayFab server , the deployment still fails, likely due to the unhealthy state.

Thank you for your support, and please let me know if there’s anything I can test or provide to help move this forward!

hi @shiva30122 and thank you for trying PlayFab!

The lack of clear video tutorials or updated guides for uploading new servers makes it even tougher.

Have you seen the videos here? https://github.com/PlayFab/MpsSamples/blob/main/videos.md

Are there logs on the VM, and if so, how can I check them?

Two ways

• accessing logs from past game servers (game server process terminated either gracefully or crash): https://learn.microsoft.com/en-us/gaming/playfab/features/multiplayer/servers/archiving-and-retrieving-multiplayer-server-logs
• SSH into the VM https://learn.microsoft.com/en-us/gaming/playfab/features/multiplayer/servers/directly-debugging-game-servers

Also, I'd highly encourage you to check our LocalMultiplayerAgent utility, this can help debug GSDK issues before you upload your game server on PlayFab, thus saving on $$$.

private const string GsdkConfigFileEnvVarKey = "GSDK_CONFIG_FILE";. I’m unsure what this variable should contain

This sounds like issues with GSDK integration. I'd recommend you test your game server binary first with LocalMultiplayerAgent, to make sure the GSDK has been configured properly.

If you’re updating the sample, I believe just providing server build code might not be sufficient.

Updating the Mirror sample is on my backlog, hope to get to it fast.

Again, thanks for using PlayFab and let us know how we can help!
