Fixing common multiplayer issues
Solutions to common problems with networked state machines.
Problem: Nodes don't execute on other clients.
Checklist:
Verify the networking module is installed correctly
Check that Network Settings are configured on the node
Ensure the PhotonView/NetworkObject is on the same GameObject
Verify the client is connected to the network
Problem: Clients show different states.
Causes:
Non-deterministic logic (random values, time-based conditions)
Different state machine asset versions
Race conditions in transition logic
Solutions:
Use seeded random with a synced seed
Ensure all clients have the same asset version
Add proper synchronization points
Problem: Players joining mid-game have incorrect state.
Solutions:
Store important state in synced variables
Use the current node state, not transition history
Initialize UI based on current variable values
Problem: Game slows down with many networked state machines.
Solutions:
Reduce the number of networked nodes
Use Run on Master for heavy AI calculations
Sync results instead of processes
Batch actions into fewer nodes
Problem: "RPC target not found" or similar errors.
Causes:
PhotonView/NetworkObject not properly set up
Target client disconnected
Incorrect authority settings
Solutions:
Verify network components are on the same GameObject
Add null checks for disconnected clients
Review authority configuration
Problem: Can't see network settings in node inspector.
Solutions:
Verify Fusion Module or Photon Module 2 is installed
Restart Unity after installing the module
Check for console errors during import
Problem: Nodes running on wrong client.
Checklist:
Verify PhotonView ownership is correct
Check NetworkObject authority settings
Ensure Run on Owner is set for player-specific logic
