I found some time to mess with the code today. I still am so confused about the whole authority thing. I have a body being generated by the spawner, and according to the prints they are being named correctly. All clients (host included) see all bodies but only the host moves (the clients arent moved by the host now though). The camera of the clients moves automatically to the host. I put in an ingame chat to see what is going on with the whole authority thing.
add operator:1
operator ID:1
Operator added with name:1and authority ID:1
1
add operator:750019725
operator ID:750019725
Operator added with name:750019725and authority ID:750019725
1
add operator:1367095416
operator ID:1367095416
Operator added with name:1367095416and authority ID:1367095416
1
add operator:1885263129
operator ID:1885263129
Operator added with name:1885263129and authority ID:1885263129
1
my prints basically are taken multiple points throughout just to confirm that the process is working. What is weird is that the bodies are being set correctly, but the bodies are unable to move?
In fact when I was using the chat box with the ID attached to the chat it was empty (empty text : random text here) comprated to the host (1:random text). The host then would change to 750019725:text, then 1367095416:text, etc. The host seems to take the authority instead of the clients? while the bodies which I thought was getting the authority didn’t.
Got a new fun error which basically tells me Authority isnt being set:
E 0:00:30:0495 on_replication_start: The MultiplayerSynchronizer at path “/root/Origin/GatheringHub/gathering_hub_spawner/97566485/PlayerInputSynchronizer” is unable to process the pending spawn since it has no network ID. This might happen when changing the multiplayer authority during the “_ready” callback. Make sure to only change the authority of multiplayer synchronizers during “_enter_tree” or the “_spawn_custom” callback of their multiplayer spawner.
<C++ Error> Condition “pending_sync_net_ids.is_empty()” is true. Returning: ERR_INVALID_DATA
<C++ Source> modules/multiplayer/scene_replication_interface.cpp:244 @ on_replication_start()
Basically its saying my input synchronizer is wrong? but I cant find it.
I am posting the full code, It is probably barely functioning with how much I deleted, and readded things. So some parts might not be needed/functional. I appreciate your help on this so far, I imagine If I don’t have it working by the end of the week, im just gonna abandon the multiplayer part and move on the the next thing to experiment on.
