    Hi everyone

    A real pleasure to announce that Multiplayer Play Mode v0.1.0 is now available as an experimental package.

    Multiplayer Play Mode (MPPM) enables you to test multiplayer functionality without leaving the Unity Editor. You can simulate up to four Players (the Main Editor Player plus three Virtual Players) simultaneously on the same development device while using the same source assets on disk. You can leverage MPPM to create multiplayer development workflows that reduce the time it takes to build a project, run it locally, and test the server-client relationship.

    Requirements:
    • Unity Engine: 2023.1.a22 or above
    • Install the Unity Engine version here: https://unity.com/releases/editor/alpha
    • Install the package by name `com.unity.multiplayer.playmode` (version 0.1.0 or later)
    Known Issues:
    • Player windows cannot be reopened if they are closed during Play Mode
    • Virtual Players can remain in Play Mode after the Main Editor has exited in certain circumstances, such as if script changes are made during Play Mode and the “Stop Playing and Recompile” option is active.
    • Entering Play Mode with multiple scenes open is not currently supported
    • Virtual Players lose some Game View settings, such as Aspect Ratio, when exiting and entering Play Mode
    • Opening a Virtual Player with unresolved script updater issues will cause an API Update prompt to appear
    • Scripts will not be reloaded correctly in Virtual Players with “Enter Play Mode” settings set with “Reload Domain” disabled
    • In some cases, an error may appear in Virtual Player windows indicating that assets were imported when they were not supposed to be
    • Non-prefab assets like Scriptable Objects are not synced to Virtual Players unless you save your scene or invoke the Save Project command
    • Authentication with UGS will not work without manually overriding configuration values at runtime
    • Documentation is live: https://docs-multiplayer.unity3d.com//tools/current/mppm
    Feedback:

    Please open new threads on the Multiplayer Netcode for GameObjects subforum. Make it clear in the title that you are referencing MPPM. Alternatively, please use the #multiplayer-tools channel on the Multiplayer Discord Server: https://discord.gg/unity-multiplayer-network.

    Thanks on behalf of the Multiplayer Tools Team,
    Chris

    Awesome! This is one of the biggest game-changers for Multiplayer game development in Unity! It used to be very cumbersome to do any rapid testing.

    Thanks! By any chance will this be ported to 2022.2-3 versions?

    Better late than never.

    Any chance this will be backported to at least 2022.x?

    The package is experimental and might be not stable.
    For this reason, it does not appear in the package manager by default.
    If not done yet, could try to enable "enable Pre-Release packages" in the project settings ?

    Unfortunately not at this time. The engineering team made changes to the engine which were needed to enable this workflow.

    So if we are developing in 2022.X we will be forced to update without chance of sticking to 2022 lts...

    @joan_stark @m0guz if you're on 2022 or lower, you can still use ParrelSync. Even if it's not an official Unity product it works pretty well (I use it in production projects) and covers MPPM's use case

    @RikuTheFuffs-U How does one go about reading the tags you set in MultiPlayer Play Mode? (for Main Editor, Player 2, etc) .. How can you figure out which one to do StartHost() on and StartClient() on?

    Nevermind found it. Unity.Multiplayer.Playmode.CurrentPlayer.Tag :)

    @RikuTheFuffs-U Do you have to deactivate / reactivate a player every time you make a code change? Mine seems to only update when I do that. It's pretty slow doing that, am I missing something?

    ParrelSync open clone editor too slow, user experience is not good.

    ParrelSync cloned projects open the same speed as any other editor instance after the initial copy was made. However if you only have 8gb of memory then surely two unity editor instances will slow things down quite a bit.

    On the documentation, there is this mention:
    "There’s no restriction on where you can keep these scripts that work with Player Tags, but you must attach the scripts to a NetworkObject (such as the Player)."

    1. The link to NetworkObject seems to be broken.
    2. Does that mean we need to use one of Unity's multiplayer package in order to use tags (Netcode for X)? For example, my project uses Photon Bolt.
