NetworkBehaviour namespace could not be found

Hi, I'm having a problem with using NetworkBehaviour even though I have added the required namespaces my visual studio doesn't recognize NetworkBehaviour.
Here is a picture:

NetworkBehaviour has been deprecated in 2019.1. See blog post here: https://blogs.unity3d.com/2018/08/0...65.1606307406.1556038404-136028431.1556038404

Deprecated, not removed...so why can't we use it still?

 

You can use it, add the proper package to your project through package manager and you can use it. VS recognition is not necessary to use it. It is deprecated, do not expect support for this package.

 

which package should we use

 

Also me I would like to know it

 

The package is "Multiplayer HLAPI"

 

I'd go with Mirror instead of installing the HLAPI package.

 

Or MLAPI if you want Unity-backed solution.

https://docs-multiplayer.unity3d.com/

 

What do I use instead of NetworkBehaviour. I am using Mirror API but the tutorial I was following is using HLAPI.

 

Mirror and the Unet HLAPI are very similar. This is because Mirror actually is a fork of the Unet HLAPI original code. So in most cases instructions or tutorials for Unet work almost unchanged with Mirror. You can see the specific differences in the Mirror migration guide:
https://mirror-networking.gitbook.io/docs/general/migration-guide

 

using UnityEngine;
using UnityEngine.Networking;

public class PlayerSetup : NetworkBehaviour {

[SerializeField]
Behaviour[] componentsToDisable;

void Start ()
{
if (!isLocalPlayer)
{
for (ints i = 0; i < componentsToDisable.Length; i++)
{
componentsToDisable.enabled = false;
}
}
}

}

 

pls can someone also help im having the same problem

 

Did you even read the first response?!!!!! Here, I'll copy it for you:

It's more than halfway through 2022. That entire subsystem is probably long gone by now.

And please don't necro-post. Start your own post. When you post, keep this in mind:

How to report your problem productively in the Unity3D forums:

http://plbm.com/?p=220

This is the bare minimum of information to report:

- what you want
- what you tried
- what you expected to happen
- what actually happened, especially any errors you see
- links to documentation you used to cross-check your work (CRITICAL!!!)

If you post a code snippet, ALWAYS USE CODE TAGS:

How to use code tags: https://forum.unity.com/threads/using-code-tags-properly.143875/

 

so instead of network behaviour what can i use

 

These guys might have some info:

https://forum.unity.com/forums/multiplayer.26/

 

Actually, Netcode for GameObjects package uses the class

NetworkBehaviour

.
https://docs-multiplayer.unity3d.com/netcode/current/basics/networkbehavior

If you use the Netcode for GameObjects package and VS doesn't recognize the NetworkBehaviour class. Then regenerate the csproj files.

 

Why arent any of you telling what to just type instead of network behaviour after using Mirror;

 

Because odds are you don't have to type something instead of NetworkBehaviour. Its still used by Mirror, Fish-Net, Netcode, and likely other networking solutions. If you IDE is not showing it as valid you likely need to go to preferences make sure an external script editor is loaded and regenerate project files.


Hope that helps anyone else finging this as the top search result.
