PUN 2 UWP Build Errors

rowlandjonathan

I am using Unity 2019.4.10. I am able to import PUN 2 and no errors are displayed after importing. But when I try to build for UWP then I am getting 113 errors.

Some errors include :

1. Assets\Photon\PhotonChat\Code\ChatPeer.cs(16,11): error CS0246: The type or namespace name 'ExitGames' could not be found (are you missing a using directive or an assembly reference?)
2. Assets\Photon\PhotonChat\Code\ChatPeer.cs(46,25): error CS0246: The type or namespace name 'IPhotonPeerListener' could not be found (are you missing a using directive or an assembly reference?)

Using PUN 2 (2.22 version)

Hi @rowlandjonathan,

Thank you for choosing Photon!

If you don't use Photon Chat try removing it completely and rebuild.
Remove whole folder "Assets\Photon\PhotonChat".

Hi @JohnTube I have deleted the Photon Chat folder and now its reduced to 70 errors. I don't think I can delete files to solve any more errors. Here are some of the errors

1. Assets\Photon\PhotonRealtime\Code\Room.cs(25,23): error CS0246: The type or namespace name 'ExitGames' could not be found (are you missing a using directive or an assembly reference?)
2. Assets\Photon\PhotonRealtime\Code\Player.cs(23,11): error CS0246: The type or namespace name 'ExitGames' could not be found (are you missing a using directive or an assembly reference?)

Hi @JohnTube I just found this link https://doc.photonengine.com/zh-tw/pun/v2/troubleshooting/known-issues. Since I am using Unity 2019.4.10 (LTS) it automatically uses the IL2CPP scripting backend but how do I make sure that the "Photon3Unity3D.dll is used from /Assets/Photon/PhotonLibs/ directory" ?

rowlandjonathan

Solved the errors by changing the Photon/PhotonLibs/Metro/Photon3Unity3D.dll's import setting. Changed the scripting backend as 'IL2CPP' with only WSAPlayer platform selected.

Hi @rowlandjonathan,

Thank you for sharing your fix.
I think we were assuming that when IL2CPP is used, we automatically target .NET 4 and then "Photon/PhotonLibs/netstandard2.0/Photon3Unity3D.dll" will be used instead.
We will review.

I was having exactly the same issue. How did you solve it

ylhubeiwuhan

How can I solve this problem

rowlandjonathan

I think the new versions automatically sets the right import setting . I didn't have to change settings with new version. @ylhubeiwuhan

Tobias

Yes, PUN 2.23 should have this fixed. It's easier you update, as you don't seem to know how to fix the export settings.

Joaquin

wow, 2023 and this bug is back

We can't build for UWP in IL2CPP, i've tried changing the export settings, the placeholder, everything... no luck
