1. Core Changes In version v52, we have refactored the underlying architecture of UNI's multiplayer system.

• Old Mechanism: All scripts were forced to execute on the client side.
• New Mechanism: Added a Server Execution option. Script execution effects can now be precisely controlled to either "synchronize across all players" or "take effect only on specific clients."

1. Execution Modes You can toggle the execution side via the button located above the Event Name.

A. Server Execution —— Default Recommended

• Logic: Script logic is processed centrally by the server, and results are forcibly synchronized to all players.
• Behavior: All clients see exactly the same effect.
• Use Cases:
  • Modifying player attributes (e.g., increasing movement speed).
  • Environment interactions (e.g., object movement, color changes).

B. Local Execution —— Differentiated Behavior

• Logic: The script runs only on the client (local) that triggered the event.
• Special Rules:

  • Set to Statements: Support differentiated states. You can configure whether this statement synchronizes or not. If set to not synchronize, attribute modifications are only visible locally (e.g., Player A sees a red block, while Player B sees the same block as green). This is highly useful for faction-based PvP games.

    

  • Execute Command Statements: Always Synchronized. Even within local events, logic triggered via commands will still broadcast to all clients.

• Use Cases:
  • Private interactions (e.g., a door opens only for the player who pressed the button, while appearing closed to others).
  • Faction/Character-specific visual effects.

1. Restrictions & Removals

• UI Event Lock: UI-related events only support Local Execution. This setting cannot be changed.
• Feature Removal: As the new functionality covers the original logic, the old Network Setting option has been removed.

1. Known Issues

• Debug Discrepancy: The current "Debug" functionality only runs locally and cannot simulate the server environment. Therefore, behavior observed during debugging may differ from the actual synchronized behavior during multiplayer gameplay.
• Plan: We will add a "Multiplayer Debug" feature in a future version.
