[Netcode, Playmode] How to check if Playmode is started as server or client

Hi, im new to Unity and Netcode and i have a question:
With netcode i can choose if the playmode is starting as client, server or both over "Multiplayer" -> "PlayMode tools", how can is check in a c# script if im running as server or client?
The "UNITY_SERVER" definition is set when i build the game and then run it, is there something similar in playmode?

 

Well, a workaround would be to check the worlds that got created. If there is a server world, the game also runs the server. On the other hand: why do you want to check this?

 

I took a look into the package sources and inside "ClientServerBootstrap" i found the following line:

Code (CSharp):

1. public static PlayType RequestedPlayType => (PlayType) UnityEditor.EditorPrefs.GetInt("MultiplayerPlayMode_" + UnityEngine.Application.productName + "_Type");

I assume you could use the same code to determine the playtype, but don't forget to surround it with

#if UNITY_EDITOR

and

#endif

, because otherwise it'll work in the editor but not in a build.

 

I am using a NetworkUtility class:
(note: i am only using the Simulation Gorups)

Code (CSharp):

1. public static class NetworkUtility
2. {
3.     public static World GetServerWorld()
4.     {
5.         return GetWorld<ClientSimulationSystemGroup>();
6.     }
7.  
8.     public static World GetClientWorld()
9.     {
10.         return GetWorld<ClientSimulationSystemGroup>();
11.     }
12.  
13.     private static World GetWorld<TWorld>() where TWorld : ComponentSystemGroup
14.     {
15.         foreach (var world in World.All)
16.         {
17.             if (world.GetExistingSystem<TWorld>() != null)
18.             {
19.                 return world;
20.             }
21.         }
22.         return null;
23.     }
24.  
25.     public static bool IsClientWorld(World world)
26.     {
27.         return world.GetExistingSystem<ClientSimulationSystemGroup>() != null;
28.     }
29.  
30.     public static bool IsServerWorld(World world)
31.     {
32.         return world.GetExistingSystem<ServerSimulationSystemGroup>() != null;
33.     }
34. }

 

@Flipps: your

GetServerWorld

and

GetClientWorld

do the exact same thing. I guess the server one is supposed to use the

ServerSimulationSystemGroup

, isn't it?

 

Thanks both of you!
Richard, your solution works fine.
Thanks Flipps for your solution, i'll try that one, but first i'll have to read more about SimulationGroups etc.

EDIT: i want to check this, because i have one project for the client and the server and i have a empty scene to start with in which i check if i have to load a "menu scene"(if started as client) or if i can directly load the real game scene.

 

You are right, thanks for the hint!

 

I didn't do it myself, but the documentation mentions that you can implement your own bootstrapper with your own, custom logic (and your own configuration).

and @Flipps code is basically my first suggestion. Since you probably want to create your own bootstrapper, it looks more like a workaround to me tbh.
