Multiplayer

Multiplayer integration with Photon Fusion and PUN2

State Machine 2 provides built-in support for multiplayer games using Photon Fusion or Photon PUN2.

Requirements

To use multiplayer features, you need one of the following modules installed:

Module	Networking Solution
Fusion Module	Photon Fusion
Photon Module 2	Photon PUN2

The multiplayer features in State Machine 2 appear automatically when either module is detected.

Per-Node Network Settings

Each node in a state machine can have individual networking configuration:

1. Select a node in the Graph Editor

2. Expand Network Settings in the Inspector

3. Configure the sync options

Network Options

Option	Description
Run on All	Execute on all clients
Run on Owner	Execute only on the owning client
Run on Master/Host	Execute only on the host/master client
RPC	Send as a Remote Procedure Call

State Synchronization

State Machine 2 automatically handles state synchronization for networked games:

Node State Sync

• Active node states are synchronized across clients

• Transitions are replicated to maintain consistency

• Late-joining clients receive the current state

Variable Sync

State Machine variables can be synchronized:

1. Open the Blackboard

2. Select a variable

3. Enable Network Sync (requires Fusion/Photon Module)
