What is this?

Easy Packets (EP) is an Unity asset which makes it more convenient to send and handle messages in your Unet HLAPI applications. Unet RPC's make everything ugly and complex, and standard messages lack a lot of convenient functionality, which is why I made this asset. I've been using it for quite a while, and I can't imagine working with Unet HLAPI without it.

This packet is not something BIG that you add to your games - it's something extremelly small, simple, and makes it a lot more enjoying to write networking code.

Why would you use it?

• Can be used as framework/base for building your networked applications
• Allows replying to messages directly (main reason why I wrote this)
• Messages can be created on the fly (written directly to writers)
• On the server, it is easy to see who sent a message (which peer) and modify it's state
• Uses same transportation method as Unet HLAPI messages
• It makes your code beautiful (check out the examples)
• It's small, robust and performant

Introduction/history (not necessary to read, but in case you're interested )

For the past year, I have been working on a few multiplayer games with UNet. What I found was that it was a very common use-case to reply to messages, sent by users - for example, when a client sends a request to buy something, server needs to respond about the status of purchase.

As projects grew bigger, it became a huge hassle to use standard Unet messaging API (inheriting MessageBase) or RPC's (creates bunch of spaghetti code). To remedy that, I wrote a few small wrapper scripts and other convenient methods, which became a base for any Unet app that I write.

As time went by, I found myself copying these wrappers to use from one project to another, as work without them became very tedious. I shared it with some of my collegues, and they kept insisting - "why don't you make it into an asset? I'm sure there are more people who could use this".

So here I am, sharing this as my first asset, hoping to make a few extra bucks on the way, haha

 

Hey there, just picked this up and am excited to try it out.

 

Hey!

Thanks! Let me know how it goes or if you have any problems or suggestions

 

Hey! I can’t understand why you are ignoring the email, it’s quite possible that the question is too dumb, but this is just one question. I can’t continue to work on the project because of this problem for 2 weeks.

And I can not ask this question to anyone else, because for this I will have to somehow show the rest of the bunch of Multiroon-expample-Epackets code. It is unlikely anyone will want to figure this out.

Therefore, I ask this question here hoping for luck.

My project works well until I made the implementation of the "character selection" before the game.

I did it like that:

Code (CSharp):

1.  
2. /////////////[server side]////////////////////////////////////////////////////////////////
3. protected virtual IEnumerator GameLoop()
4.         {
5. //...........Other_Code.................//
6. StartCoroutine(PickedPresident(user_array));
7.             //just need wait all pick, then continue game loop
8.  
9.             while (!_allpick) yield return null;
10.             StopCoroutine(PickedPresident(user_array));
11. //............Other_Code................//
12.         }
13.  
14.  
15. private protected virtual IEnumerator PickedPresident(User []user_array)
16.         {
17.             int checker = 0;
18.             Ep.Server.SetHandler(1, message =>
19.             {
20.                 var peer = message.Peer;
21.                 string president = message.Reader.ReadString();
22.                 message.Respond(ResponseStatus.Success, "Picked");
23.                 for (int i = 0; i < _roomSize; i++)
24.                 {
25.                     if (peer == user_array[i].id_in_room)
26.                     {
27.                         if (user_array[i].president == null)
28.                         {
29.                             user_array[i].president = president;
30.                             checker++;
31.                             if (checker == _roomSize)
32.                             {
33.                                 _allpick = true;
34.                             }
35.                         }
36.                     }
37.  
38.                 }
39.  
40.             });
41.             yield return new WaitForSeconds(1f);
42.  
43.         }
44. /////////////////////////////////////[client side]/////////////////////////////////////////////////////////////////////////
45. public void ClickedToPick()
46.         {
47.            //.....Other_Code....//
48.             Ep.Client.Send(1, writer => writer.Write(president), response => { Debug.Log("Response received: " + response.Status + " " + response.ToString());});
49.         }
50.  

And everything works as it should, as long as there is only one room on the server. But when you want to create another room, it is not created and the following error is displayed.

 

I use mirror version 30.5.3,and then this package log err,plz help to fix it. Assets\SpaceApple\EasyPackets\Scripts\ByteMessage.cs(9,32): error CS0619: 'MessageBase' is obsolete: 'Implement NetworkMessage instead. Use extension methods instead of Serialize/Deserialize, see https://github.com/vis2k/Mirror/pull/2317'

 

Why do I get this error? Assets\SpaceApple\Networking.Core\NetWriter.cs(385,21): error CS0103: The name 'LogFilter' does not exist in the current context

Now do I fix that?

 

I get an error. Assets\SpaceApple\Multiroom.PvP\Editor\Scripts\QuickBuild.cs(5,32): error CS0234: The type or namespace name 'UIElements' does not exist in the namespace 'UnityEngine.Experimental' (are you missing an assembly reference?)

I change using UnityEngine.Experimental.UIElements;
to using UnityEngine.UIElements;

seen to work

 

Did you end up finding the fix for this?

 

from a clean install with unity 2019 and last mirror version
