Hello, I need help with a problem I am getting in my Unity project. I am making a phone game and I use photon to connect.
I connect from my unity project and my phone and it works to connect but then when it starts, I see different things happening on both screens. I have been working to figure out how to synchronize both games but no success.

I am also using ai to help figure out what is going on and still not fixed.

Does anyone know if this is a problem with me using Photon for a phone game or something else?

Thanks

You'll have to be more specific than that. Photon libraries definitely work on mobile. One of them is primarily designed for mobile.

Sounds like you might be running as host on both devices and they are not actually connecting

What should I say to be more specific?

Oh, that is a good point, I will check that in the project.

lavish compass What should I say to be more specific?

Desync can take on many forms and happen for a variety of reasons. Just saying "I use Photon and I see different things on both screens" is not enough detail for anyone to help you.

#

Ideally you would try to debug your issue further so you can provide more detail about the problem.

Also, desync implies things were synced at some point

I am also learning how to communicate the problem since I am new to this. Sorry for not knowing yet how to describe the problem better

They are synced at the begging of the game. It shows correctly and spawns correctly the champs. Also the team positioning is good.

#

I will try to see if both devices run as host as you said.

#

Well if they are both running as host, then you wouldnt be seeing other player at all. They would be in 2 different sessions

#

I don't use Photon and don't know exactly how their shared authority works if you are using that

It makes sense what you say and that might be the issue based on what I am experiencing. Thank you.

Once I get a change to change that will update

Seems like it's not the same host but that helped me find a different approach to figure out what is going on.

Right now I am checking to see if the games start in the same room or different rooms.

#

So I have at least a next step until I figure out why I don't see the same things.

Somehow it does not recognize as the same room. Having Ai review the implementation of the photon network function to figure out where stuff went wrong.

So far tho, the games connect and it show there are 2 players in the game, one of them is host, still characters go different ways in the game. So have to find out why I see different things in the unity app and phone that are connected in multiplayer.

Update.
It does work to connect to the same room but I think my problem is the movment of the champions. So once I get that fixed, it should give me a better ideea of what is happening or if there was any problem in the first place.
