uMMORPG Official Thread

Please check out the mirror documentation to get comfortable with it

 

Looks like you did not get it. Server's connection to Server is always null. And if I give authority over bot to null - bot does not have authority to execute commands.

 

@vis2k Why uMMORPG does not use any object pooling techniques for monsters, projectiles and visual effects?

 

@vis2k
Since SpatialHashing needs to react on bots and they must be able to execute Commands, this is the way of doing that:

1. Server needs to have LocalConnection authenticated
2. Server needs to ActivateHostScene
3. Server's NetworkClient should be ready
4. Ownership over bots should be given to server's local client.

So I added that to NetworkManager.cs and call it from my script with OnStartServer

Code (CSharp):

1. public void AddHost()
2. {
3.     if (NetworkServer.active && !NetworkServer.localClientActive)
4.     {
5.         OnStartHost();
6.         // FinishStartHost has NetworkServer.SpawnObjects
7.         // which we alerady executed on StartServer
8.         // Lets call ConnectHost and StartHostClient manually
9.         NetworkClient.ConnectHost();
10.         StartHostClient();
11.     }
12. }

Later on in Update I call

Code (CSharp):

1.  if (NetworkServer.active && isServer && NetworkServer.localClientActive)
2.     {
3.         if(NetworkClient.connection.isReady)
4.         {
5.             // Spawn bots to NetworkServer.localConnection
6.         }
7.         else
8.         {
9.             if(NetworkClient.connection.isAuthenticated)
10.             {
11.                 NetworkClient.Ready();
12.             }
13.         }
14.     }

All of that equals to Host (Server + Client) mode. Except that NetworkClient is set Ready manually in Update (Because in standard case it is set Ready only when player character is selected from menu and it bugs out if I set it ready in my AddHost() function because it happens before authentication).

Unfortunately it looks like this is the only way.
And no, Mirror documentation does not say anything about that.

UPD: It works without errors until bot calls for Player.localplayer.

 

I want to modify the ui of the party on the left side of the interface. But I can't find where it is. Where can I find the corresponding code?

 

Canvas->HealthMana UI

 

Where can I use "AoE Skills"?

 

You can use the ScriptableSkill system to implement any type of skill that you like.

 

where do I get a good ubuntu server host? i ent to namecheap but that seems outdated.

Or just a good server to host in general. I'd really prefer windows than that commandline stuff

 

Google cloud is easiest imho.
Can just rent / remove any time without stupid contracts.

 

Didnt you used to sale an asset that was a different type of play style. That wasn't a MMO. where you had a character that had to fight through stuff.

 

Yes, uSurvival

 

Can mmorpg games use sqlite database?

 

Yes. uMMORPG already does.

 

Thank you so much

I was looking to make a hearthstone script but I didn't succeed and I need help.

 

Can I apply this asset to VR games by replacing the player controller or use other VR assets to this asset? for example, VR Interaction Framework

 

Any controller that you want to use needs to work with Mirror.
For VR you probably need first person controller.
So in that case, my other asset uSurvival might be better, it has first person.
AFAIK my character controller is the only one for Mirror. It's quite difficult to make, I don't think anyone else made one.

 

If I have already bought uMMORPG Remastered - MMORPG Engine, will I have to buy Easy Character Movement 2 (80$) as well?

https://assetstore.unity.com/packages/tools/physics/easy-character-movement-2-193614


Can I use movement with your Engine?

 

just replied to your dm already

 

Could you briefly go over the pros and cons of usurvival versus ummorpg? Is there a link already made? I'm debating on what package I should purchase.

 

uMMORPG is based on uSurvival, it's almost the same architecture.
uSurvival has character controller & first person.
uMMORPG has skills, quests, etc.

 

Clean download to unity 2019.4.37
and The uMMORPG has this errors.

Assets\uMMORPG\Plugins\NavMeshComponents\NavMeshComponents\Editor\NavMeshAssetManager.cs(276,46): error CS0246: The type or namespace name 'PrefabStage' could not be found (are you missing a using directive or an assembly reference?)

 

Please use at least Unity 2020 LTS .
Ideally 2021 LTS.

 

Hey guys! Does anybody know if it’s possible to use the collisions with Tilemap using RuleTile? When I press “bake” he’s ignoring it ...

 

Navigation2D only works with Unity's built in Collider2D/Tilemap/etc.

 

Hi there @vis2k !
Hopefully you are doing well, I'm posting here because I'm not entirely sure how to properly solve this since the newest mirror changes.
On line 1246 in NetworkManager.cs the OnClientConnect() method invokes a NetworkClient.Ready() method.
Now the OnClientConnect() method will be called when a player logs-in to view their character previews.
Which seems fine, however the issue is in the class UICharacterSelection.cs on line 43 it also calls NetworkClient.Ready() when you click the "Start" button.

This double calling of NetworkClient.Ready() is giving me a a mirror runtime error telling me to not call Ready() method more than once.
Which makes sense, however do I simply just remove the Ready() method call in the Characer Selection since it will be called in the OnClientConnect() method or do I need to make sure not to call Ready() until the character is out of preview stage and actually in the game?
Because a player shouldn't be getting any packets/syncvar/etc when they are just in the preview stage correct?

Thanks!

 

I'll update to latest Mirror asap.
Best not to worry about it, let me worry about it for you

 

Okay thanks, also I am very worried about Unity's server build with ummorpg right now.
I just built a test build of both Server and Client and when running the server it shows a lot of "mesh" and "shader" stuff for supposedly running on "server mode" which should not worry about any graphics or materials.....
I am using Unity LTS 2021.3.0f1
Do you know why it's doing this? And or what's going on... I'm just worried about these messages.
Links: https://i.ibb.co/1rb3fnB/s2.png + https://i.ibb.co/HdjDn67/s1.png

 

@vis2k To addition to my last post, does the latest mirror need any specific unity version?
Because honestly... I am having the urge to download the project to like the 2019 LTS or 2020 LTS where Unity didn't fack around with the "dedicated server build" mode.

 

Mirror works with 2020+ LTS.
Looks like the server build performance issue is only apple silicon.
Fakebyte tested it in discord, and it's same perf as desktop on windows.

 

Great, thanks for the info!

Also if I can get a tiny bit of help to solve this issue with my small change to uMMMORPG.
I am attempting to delete all "character selection" feature. Just login and your in your one character/account.

So I have all this going on:
When client types user and pass, it sends LoginMsg.

Server's LoginMsg receiving:

Code (CSharp):

1. void OnServerLogin(NetworkConnectionToClient conn, LoginMsg message) {
2. // checks if user + pass is good
3. conn.Send(new LoginSuccessMsg());
4. OnServerAuthenticated.Invoke(conn);
5. GameObject go = null;
6. if (Database.singleton.CharacterExists(message.account)) {
7.     go = Database.singleton.CharacterLoad(message.account, playerPrefab, false);
8. } else {
9.     go = manager.CreateCharacter(playerPrefab.gameObject, message.account, message.account).gameObject;
10. }
11. NetworkServer.AddPlayerForConnection(conn, go);
12. }

However when I test this, I get this error message from Mirror:

No ready connection found for setting player controller during InternalAddPlayer

What am I missing to do on the client side to make this connection ready?
I see there is a method called NetworkClient.Ready() however, where would I issue that? And if that is even the fix?
Thanks!

 

@vis2k

I found a little buggy.

• Missing [GM] Tag on players name, even though they're marked with GM Status. Seems like the code was removed for this in the player.cs file. I've reverted it back unless theirs a actual reason for this.

 

@vis2k I'm running the demo world in uMMORPG Remastered, but when my character goes into the little rock crevice where the dungeon teleporter is, nothing happens. How can I get this teleport to work correctly?

 

You need to be in a party with other players

 

allowing for single player "missions" might be a good thing

 

You can disable the party requirement in the script, there are two InParty() checks that you can comment out.

 

uMMORPG and DOTSNET are on sale.
I think it's -40% but occasionally -95%.
For me it jumped to -95% after a few seconds.

 

Running a dedicated server within wsl, clients can't connect to it (it is working fine when running the same exact build on native ubuntu). Any ideas why this might be happening?

 

Any errors in the console on client?

 

It times out with this message:

KCP: Connection timed out after not receiving any message for 10000ms. Disconnecting.
UnityEngine.Debug:LogWarning (object)

Mirror.NetworkLoop:NetworkEarlyUpdate () (at Assets/uMMORPG/Plugins/Mirror/Runtime/NetworkLoop.cs:194)

 

Didn't you say you use wsl / websockets?
The above log is for kcp, which is for UDP sockets.

 

Meant Windows Subsystem for Linux

 

I see. Sounds like some kind of firewall issue then.
Kcp transport is used in production by a lot of projects, and generally works

 

Seems to be a problem related to wsl and mirror (maybe wsl handling of udp doesn't work with mirror?). You're right though, production should work fine (working fine with native ubuntu). Problem only exists in test environment using wsl.

 

Is there a way to provide an API to the uMMORPG Inventory system ?

@vis2k

To add an item / remove / fetch items to a user?
