How can I make peers make changes to a scene and have it syncronized?

UnknownUser

Hello there, I got into networking recently and its all a bit new to me. I was thinking of making something to mess around with a friend and I wanted to make some sort of system where a host or a peer can spawn an object and everyone will be able to see it or a host or a peer can delete an object and the object will be deleted for everyone.

I was wondering how you can do that, do you have to sync everything with RPC? I tried syncing and stuff but it didn't work. Hopefully someone can answer me as I googled this and didn't get many results.

I also have not really done any networking with Godot beyond some basics, but I there is a networking demo on the Godot demo repository that may be helpful. From what I remember, the bombs in the demo are spawned by one player and visible on all connecting machines.

Thank you, TwistedLeg. Hopefully this works in 3D too, it should, I'll test it.

Hello, TwistedLeg, I played around with rpc remote functions and created a box in a scene that you can delete by doing something and they work when the player has joined after the host, and the host or peer calls the function. But it doesnt work before the peers connect, as the box will be there.

Got any ideas?

Hmm, not sure right off. Maybe have the host hold a list of deleted objects (or some other reference, like their names) in the scene, and then when a new peer connects, send the list to the peer so it can delete the nodes if they have not already been deleted?
