[ClientRpc]

[ClientRpc] attribute is used when the server calls a function on all clients. It is used to notify all connected clients about changes in the server's state.

Key Features

• Can only be called from the server to all clients.
• Executed on the client.
• The function name must begin with the Rpc prefix.
• Executes on all connected clients.

Use Examples

Basic Use

public class GameManager : NetworkBehaviour
{
    [Server]
    private void StartGame()
    {
        // Game start logic
        RpcNotifyGameStart();
    }

    [ClientRpc]
    private void RpcNotifyGameStart()
    {
        // Client-side logic executed when game starts
        // UI updates, sound playback, etc.
    }
}

Passing Parameters

public class PlayerStatus : NetworkBehaviour
{
    [Server]
    public void TakeDamage(int damage)
    {
        // Damage handling logic
        RpcUpdateHealth(currentHealth);
    }

    [ClientRpc]
    private void RpcUpdateHealth(int newHealth)
    {
        // Update health status on the client side
        // UI updates, visual effects, etc.
    }
}

Synchronizing Multiple Information

public class WorldState : NetworkBehaviour
{
    [Server]
    private void UpdateWeather(WeatherType weather, float intensity)
    {
        // Weather change logic
        RpcSyncWeather(weather, intensity);
    }

    [ClientRpc]
    private void RpcSyncWeather(WeatherType weather, float intensity)
    {
        // Update weather on the client side
        // Particle effects, sounds, etc.
    }
}

1. The [ClientRpc] attribute is used to notify all clients about changes on the server.
2. The function name must begin with Rpc to ensure proper recognition as a remote procedure call.
3. It is typically used to communicate game state changes, event notifications, or environmental updates to all connected clients. :::
