How does state synchronization work in a game?
The basic idea is that, somewhat like deterministic lockstep, we run the simulation on both sides but, unlike deterministic lockstep, we don’t just send input, we send both input and state. This gives state synchronization interesting properties.
Can a GameObject be sent through object synchronization?
Typically, rooms and players have some attributes that are not related to a GameObject: The current map or the color of a player’s character (think: 2d jump and run). Those can be sent via Object Synchronization or RPC, but it is often more convenient to use Custom Properties.
How to synchronize game objects in photon engine?
PUN (and Photon in general) offers several tools for updates and keeping a state. This page will explain the options and when to use each. With PUN, you can easily make certain game objects “network aware”. Assign a PhotonView component and an object can sync the position, rotation and other values with its remote duplicates.
How are RPCs different from object synchronization in Minecraft?
Unlike Object Synchronization, RPCs might be buffered. Any buffered RPC will be sent to players who join later, which can be useful if actions have to be replayed one after another. For example a joining client can replay how someone placed a tool in the scene and how someone else upgraded it.
How is state synchronization different from snapshot interpolation?
This lets us approach state synchronization differently to snapshot interpolation. Instead of sending state updates for every object in each packet, we can now send updates for only a few, and if we’re smart about how we select the objects for each packet, we can save bandwidth by concentrating updates on the most important objects.
What happens to State Update packets in real world?
What happens in the real world is you’ll typically receive two packets one frame, 0 packets the next, 1, 2, 0 and so on because packets tend to clump up across frames. To handle this situation you need to implement a jitter buffer for your state update packets.
