Avatar sync	WIP

Caution

Multiplayer avatar sync is implemented but not yet fully stable. Pallet transfers over the network are not supported yet.

How It Works

The mod uses full replacement with multiplayer synchronization:

1. When a player spawns, the mod hides the game’s character meshes
2. A DH avatar is instantiated and parented under the active character
3. Pose mirroring copies animations from the game’s Animator to the DH avatar using HumanPoseHandler
4. The DH avatar is auto-scaled to match the game character’s proportions using humanScale

Avatar barcodes are synchronized across all players using custom HLAPI network messages. When a remote player is using an avatar from a pallet you don’t have locally, the mod can request the pallet data from that player via the network.

In-Game Configuration

Config file: BepInEx/config/io.mltn.digitalheaven.ror2.cfg

Setting	Section	Default	Description
PlayerAvatar	[DigitalHeaven]	""	Barcode for the player avatar

Example Configuration

[DigitalHeaven]
PlayerAvatar = io.example.my-avatar:avatar.dh-avatar

Development Setup

The mod project lives at Games/DigitalHeaven.Games.RiskOfRain2/ and is included in the main DigitalHeaven.sln solution under the Games folder.

Local Configuration

Copy DigitalHeaven.Games.RiskOfRain2.csproj.user.example and remove the .example extension. This file configures your local game install path and is git-ignored:

DigitalHeaven.Games.RiskOfRain2.csproj.user

<Project>
  <PropertyGroup>
    <RoR2Dir>D:\SteamLibrary\steamapps\common\Risk of Rain 2</RoR2Dir>
  </PropertyGroup>
</Project>

By default, RoR2Dir is used to locate both BepInEx and the game’s managed assemblies. You can override them individually:

Property	Default	Description
RoR2Dir	(see .csproj)	Base game path. Controls everything if the other properties are not set.
RoR2ManagedDir	$(RoR2Dir)\Risk of Rain 2_Data\Managed	Directory containing the game’s managed assemblies (Unity engine, RoR2, Assembly-CSharp, etc.).
BepInExDir	$(RoR2Dir)\BepInEx	BepInEx root directory containing core\ and plugins\ folders.

Building

The project references BepInEx DLLs from $(BepInExDir)\core\ and game assemblies from $(RoR2ManagedDir). After building, a post-build target automatically deploys the mod and its dependencies to $(BepInExDir)\plugins\DigitalHeaven\.

The project targets netstandard2.1 and references DigitalHeaven.Core, DigitalHeaven.Unity, DigitalHeaven.Overlay, and DigitalHeaven.Unity.Overlay as project dependencies.
