Lua Function to Reconnect to Server on Specific Chat Message

This Lua script is designed to monitor chat messages in SA-MP (San Andreas Multiplayer). When the message "CONNECTION REJECTED Unacceptable NickName" appears, it will automatically attempt to reconnect to the server. Below is the code snippet, followed by a usage example.

Code Implementation

-- Function to handle reconnection in SA-MP
--@param chat_message: string - The message retrieved from the chat
function checkChatMessageAndReconnect(chat_message)
    -- Import necessary modules
    require "sampfuncs"  -- SA-MP specific functions library
    require "sampapi"    -- SA-MP api library

    -- Validate the input
    if type(chat_message) ~= "string" then
        error("Invalid input: chat_message should be a string")
    end

    -- Check for the specific chat message
    if chat_message == "CONNECTION REJECTED Unacceptable NickName" then
        -- Reconnect to the server
        reconnect()
    end
end

-- Function to handle reconnection logic
function reconnect()
    -- Disconnect from the server if connected
    if sampIsConnected() then
        sampDisconnectWithReason("Reconnecting due to unacceptable nickname")
    end

    -- Wait for a short period before reconnecting
    wait(5000) -- wait for 5 seconds

    -- Attempt to reconnect to the server
    local connectResult = sampConnectToServer("127.0.0.1", 7777) -- replace with your server's IP and port
    -- Check if reconnection was successful
    if connectResult then
        print("Successfully reconnected to the server.")
    else
        error("Failed to reconnect to the server.")
    end
end

Usage Example

You can integrate this function into your SA-MP script to automatically handle the reconnection process when the specified chat message occurs.

-- This is where you would capture the chat messages and call the function
function onChatMessageReceived(chat_message)
    -- Use the function to check the message and potentially reconnect
    checkChatMessageAndReconnect(chat_message)
end

-- Simulate chat message for testing
onChatMessageReceived("CONNECTION REJECTED Unacceptable NickName")

Explanation

1. Imports: The script imports sampfuncs and sampapi, which are essential for interacting with SA-MP.
2. Input Validation: The checkChatMessageAndReconnect function ensures the chat_message parameter is a string.
3. Chat Message Check: It checks if the chat message is "CONNECTION REJECTED Unacceptable NickName".
4. Reconnection: If the message matches, it calls the reconnect function to handle the server reconnection process.
   • It first checks if the player is connected, then disconnects and waits for 5 seconds before attempting to reconnect to the server.
   • The server address 127.0.0.1 and port 7777 should be replaced with actual server details.

This example highlights a robust approach to automatically reconnect to a SA-MP server on receiving a specified chat message. This architecture ensures smooth handling of connection issues related to nicknames and enhances playability experience.
