When the client or host copy paste the recipe on another building, it is not synced properly on remote players.

Client State:

Host State:

When two players connect at the same time, they will not see each other and the "Loading" message will freeze on the Host side:

The proof of concept was sending the player position and animation update as fast as possible. But this will be too much for the server. So instead I need to limit the position update to 20 times per seconds and add client side interpolation.

During our playthrough, a client was able to stack 6 labs even if the the limit was 3.

Once #76 is merged, I should update the wiki to reflect the changes done to the project setup.

Currently with the changes introduced by #74 belts do not connect when placed, there is just a round dot on the ground.

This only happened so far when i played with a friend over the network (so kinda the real world scenario).
I will work on a fix asap.

During our playthrough:

1. Client create and stack research labs
2. Client set the bottom lab recipes
3. Host only have the recipes set for the bottom lab the other one on top are not linked together

Currently when a user joins and the factory is loaded, the mesh of the planet is not transferred - this means that various parts of the factory appear to be underground to non-host players.

This is an issue to track the work on players names appearing over their heads

I am creating this for tracking purposes since I am started to work on it.

To do:

• Initial synchronization of all items that were being dropped when a player connects.
• Realtime synchronization of items removal (expiration, player pick it up)
• Real-time synchronization of items being dropped.

Since the "host" refactor, the local player colors does not seems to be applied anymore. I looked at it quickly, the method that sets the colors is called and it looks like it is modifying the material but it must be reverted after is game loaded because there is no color change for the local client. Remote clients looks to be fine.

1. Click join game while you have no server running
2. There is no "connecting" message
3. After 10 seconds you get timeout message
4. Click "Quit"
5. You get stuck in a bad game state

We should not display the reconnection message if you haven't connected successful with the host first.

As suggested by #resinate on discord, we could add a setting when you host your game to make new players spawn at a random planets, it will need to be a planet that as all the resources needed for a "first planet".

With the advent of #74, we now have a good first pass at synchronizing entity creation. We should now look at synchronizing removing entities.

The project does not come with the game DLLs, so you need to copy the game DLLs to the Libs/ folder. Then you need to drag all the Unity related DLLs to the DowgradeDll.exe executable that is in the Lib/ folder. Else you will have a lot of issues when running the code in the actual game.

To be able to host a mid / late game for our test we should add a "host game" button in the esc game menu.

When it's dark and two player are standing beside each other, they don't receive lighting from each other, making the other player very dark.

Steps i did beofre this happened:

• client travels to the planet, then leaves again into space. (this way FactoryData is received and stored locally)
• host travels there, places building (not sure if its only triggered by ILS)
• client comes back, tadaa

This may be caused by FlattenTerrain() which ic called when the building is placed.

To clean up the code, I should add a proper playerJoin packet that will make each client spawn the remote player model.

In the wiki, on the "Setting up a decelopment environment" the git clone command says:

git clone https://github.com/your-github-name/nebula.git --recursive

while it should be:

git clone https://github.com/hubastard/nebula.git --recursive

Right now, when the client quit the game gracefully (esc menu -> Quit button). The client is prompt with an unexpected disconnect popup that ask if you want to reconnect or quit. This popup should only be shown for server disconnection issues not when the client wants to quit the game.

If you change the ProtocolVersion to 1 in the HandshakeRequest server denies the client to connect but does not resume the loading screen and does not send notification packet to the other clients to resume.

Below is also an exception that is raised on the server-side:

When the host pauses the game (by pressing ESC) the game tick will stop which causes desync on all clients, since their game tick will continue increasing. I think it is needed to sync the game pause or completely remove pausing the game when navigating to the menu.

I am opening this issue for tracking purposes. I have started to work on this.
Basically, it is the synchronization of GameHistoryData class.

Progress:

• Initial research synchronization (getting finished techs from the host)
• Initial mecha stats/bonuses synchronization
• Real-time research synchronization [progress - when player contribute to the research from the mech inventory]
• Real-time research synchronization [unlocking of techs]
• Sync of features (if sailing or warping is enabled / can design Dyson sphere)
• Sync of available recipes
• Sync of bonuses from techs
• Sync of tech queue
• Real-time sync of tech queue
• Real-time sync of pausing and resuming tech queue
• Sync of pinned stars / planets
• Real-time sync of star / planet pinning

When a client builds an entity, the item is not substracted from their inventories.

If one player places a building other players need to see the same and need to be able to interact with it as if they had build it by them self.

Current status:

• buildings get placed for each player on the same planet
• terrain is flattened for each player on the same planet if needed
• miners connect to the same veins.
• power generators register as generators to the power system, consumer register as consumer.

video preview

Currently factories are requested as-needed from the host.

However, they are only ever loaded, and never unloaded, even if the player were to leave the system/planet.

Therefore, we need to implement a system to unload the factories when it is no longer required for a non-host player to have them loaded in. This can include cessation of events etc being sent/received once implemented.

Steps to reproduce:

• start mining something (not a vein, some trees, rocks or even the starting pot)
• abort before finished
• mine something else completely
• first item you started to mine will get removed for remote players

Afaik this is due to loading the PlanetFactory from the server. It does not happen for Player 1 (the hosting one) or if you disable this feature for the others.

The error that pops up in the corner is fixed by this patch

• It seems like the weird planet movement starts when ArrivePlanet() or RequestLoadPlanetFactory() (this is where we patch and the request gets triggered) gets called.
• It seems like planet comes back to normal after LoadingPlanetFactoryMain() finished atleast one of its steps (not sure if it comes back sometime after the last step or sometime inbetween).
• ModelingPlanetMain() is only called once when you load the game, so its unlikely that the cause is in there.
• uPosition of player and planet do not change significantly between the weird movement of the planet.
• GameMain.mainPlayer.transform.position does change from 0 0 0 before the request to some coordinates after the request, but does not change when the planet comes back to normal. I dont think its related to this either.

Tested on master branch.

dsp save file is very heavy

I think the analysis of the save file

using (BinaryWriter binaryWriter = new BinaryWriter(fileStream))
			{
				binaryWriter.Write('V');
				binaryWriter.Write('F');
				binaryWriter.Write('S');
				binaryWriter.Write('A');
				binaryWriter.Write('V');
				binaryWriter.Write('E');
				binaryWriter.Write(0L);
				binaryWriter.Write(4);
				binaryWriter.Write(GameConfig.gameVersion.Major);
				binaryWriter.Write(GameConfig.gameVersion.Minor);
				binaryWriter.Write(GameConfig.gameVersion.Release);
				binaryWriter.Write(GameMain.gameTick);
				binaryWriter.Write(DateTime.Now.Ticks);
				if (GameMain.data.screenShot != null)
				{
					int num = GameMain.data.screenShot.Length;
					binaryWriter.Write(num);
					binaryWriter.Write(GameMain.data.screenShot, 0, num);
				}
				else
				{
					binaryWriter.Write(0);
				}
				GameMain.data.Export(binaryWriter);
				long position = fileStream.Position;
				fileStream.Seek(6L, SeekOrigin.Begin);
				binaryWriter.Write(position);
			}

next i see GameData.Export

    public void Export(BinaryWriter w)
{
	w.Write(2);
	w.Write(this.gameName);
	this.gameDesc.Export(w);
	w.Write(GameMain.gameTick);
	this.preferences.CollectComplete();
	this.preferences.Export(w);
	this.history.Export(w);
	w.Write(this.hidePlayerModel);
	w.Write(this.disableController);
	this.statistics.Export(w);
	w.Write((this.localPlanet == null) ? 0 : this.localPlanet.id);
	this.mainPlayer.Export(w);
	w.Write(this.factoryCount);
	this.galacticTransport.Export(w);
	for (int i = 0; i < this.factoryCount; i++)
	{
		this.factories[i].Export(w);
	}
	w.Write(this.dysonSpheres.Length);
	for (int j = 0; j < this.dysonSpheres.Length; j++)
	{
		if (this.dysonSpheres[j] != null)
		{
			w.Write(1);
			this.dysonSpheres[j].Export(w);
		}
		else
		{
			w.Write(0);
		}
	}
}

and view GameDesc .Export

public void Export(BinaryWriter w)
{
	w.Write(2);
	w.Write(this.galaxyAlgo);
	w.Write(this.galaxySeed);
	w.Write(this.starCount);
	w.Write(this.playerProto);
	w.Write(this.resourceMultiplier);
	int num = this.themeIds.Length;
	w.Write(num);
	for (int i = 0; i < num; i++)
	{
		w.Write(this.themeIds[i]);
	}
}

sync the important visual and sound effects.

• #33 blocks part of tests that need to be done to complete this

Current status:

• sparkles are synced
• thrusters are mostly synced
• thruster audio effect synced on planet and space
• mining electric audio effect synced
• footsteps visuals and audio synced
• vegetation collide sound effect synced
• landing sound effect synced
• warp visuals/audio (needs some optimization)

Whats missing:

• clean up code

Right now when the host disconnect, all the clients crashes.

Sync the Dyson sphere and all its components when a player joins the server.

Current status:

• Initial Dyson Sphere synchronization
• Real-time Synchronization of Dyson Swarm orbits planning (Finished, PR ready)
• Real-time Synchronization of Dyson Sphere structure planning (Finished, PR ready)
• Synchronize Realtime Sail Bullets (Finished, PR ready)

I am creating this just for tracking purposes since I just start to work on it.

This is really hard to reproduce, but sometimes when I disconnects with the client while running I will get this error on the host:

rotation is still applied but the stick together until localPlanet of atleast one of them gets non-null again.

I am creating this for tracking purposes since I have started to work on it.

The following needs to be finished:

• Every player will generate key pair for identification.
• Host will store the last position and color of the player.
• Host will store player's inventory.
• Host will store other info such as (mecha energy, sand count, etc.)
• Host will create a separate .server save-file with info about all players.

I am opening this for tracking purposes since I have started to work on this.

The following needs to be implemented:

• Player should request statistic data when statistic window is opened.
• Server should send periodical updates to the client.
• When a player closes the window, the server will stop sending the updates.

Following statistics data needs to be synchronized:

• Production of products
• Consumption of products
• Power generation
• Power demand
• DysonSphere construction
• Research hashing

When a client joins a game where the landing pod is already destroyed, a landing pod is still created for the client the is joining the game.

This exception is thrown every FixedUpdate() call to the player who has joined the game. Seems to be caused by the stations.

Steps to reproduce:

1. You can use mine savegame
2. Launch the game normally as a single-player and from [Esc] game menu host the game.
3. Join the game with the second player and observe the error.

I am creating this for tracking purposes since I have started to work on it.

To Do:

• Initial Storage sync, when player click on the storage
• Sending real-time updates of the storage that is currently opened for the user.
• synchronize icons of the storages
• synchronize events from other players

I am creating this for tracking purposes since I have started to work on it.

ToDo:

• Assembler interactions
• Furnace interactions
• Research station interactions
• Rafinery interactions
• Particle collider interactions
• Railgun interactions
• Launching silo interactions
• Receiver interactions
• Splitter interactions
• Power Generator interactions
• Inserter interactions
• Miner interactions
• Fluid storage interactions
• Power Exchanger interactions

During our playthrough:

1. Client starts a research
2. Host enqueue another research
3. First research completes
4. The research progress panel break and still display the first research resources

During our playthrough:

1. The create the game
2. Client 1 connects
3. Client 2 connects
4. Both client 1 and 2 add a couple of buildings
5. Host starts to receive prebuild id that is not tracked in the prebuildRequest dictionnary.

You will see a warning like this on the host that will repeat overtime since the client will try to BuildFinally the prebuild forever:
BuildEntityRequest received does not have a corresponding PrebuildRequest with the id 20 for the planet 104

When you host a game and join the game with the second game instance before the first one could fully load the game one of the players gets teleported to the sun.

Not sure if that only happens to me so it would be good if someone could confirm this, tested on the master branch.

Currently, the project is using the default langversion (C# 3), but the langversion can be upgraded to at least C# 7.3 without any problems at least, and this includes the ability to use ref locals.

With ref locals you can avoid the penalty of struct copies and other stack copies, that could add up in the context of a multiplayer computation.

This should be as simple as adding <LangVersion>7.3</LangVersion> to the csproj files.

The LocalPlayer.SetReady() should be called only once the local player that is syncing is done loading the game. Right now it is called immediatly while processing the HandshakeResponse packet so the game is unpause while the client is in the loading screen.

Also, we should pause the syncing player once the player is done loading the game before he calls the LocalPlayer.SetReady(), that way he would receive the "SyncComplete" packet at the same time as the other players when the server knows that every syncing players are done loading the game (because there could have more than 1 player loading at the same time)

I'm reworking the entity placement code to be able to syncronize the entitypools / prebuildpools indices.
