Instantiate the game object for the local player only

francvol

Greetings to all, sorry for my writing, but I am Italian and I have translated the text automatically.
I have a problem that I have not been able to solve for 4 days, I am here to ask for a little help.
I'm trying to get checkpoints to work, my problem is that I add checkpoints via PhotonNetwork.Instantiate, so far everything works fine, but when I try to show or hide the checkpoints, the command has global effect.
I have made many attempts with photonView.IsMine, but have not been successful.
The goal is to show each player only their own checkpoints and not those of others.
I thank anyone who wants to help me.

Hi @francvol,

Thank you for choosing Photon!

It's OK, most of us here are not native English speakers.

About your question: first of all why do you need to network instantiate if you need it only on the local client? use Unity's Instantiate then.

Otherwise, you may want to instantiate objects as hidden and unhide them locally then? or just do this via a script next to PhotonView and hide or show in Awake or Start?

The pleasure is mine, I thank you and the staff for this fantastic tool, sure of an excellent collaboration.

A to each checkpoint I assign a status, and this must necessarily be different between the players, for this reason I generate the same number of checks for each player

I solved my problem.
I was practically trying to instantiate prefabs as inactive, but this is not allowed by Unity which automatically brings them back to active status.
While I was trying to enable only my items, the system enabled all checkpoints including those of other players.
It was enough to disable the other checkpoints to make my logic work correctly.
I hope this information will be useful.
