Roblox Lua on player chatted

Roblox Lua is a programming language used to create games and experiences on the Roblox platform. When a player chats in the game, it is possible to write a script to detect and react to the chat message using the OnPlayerChatted event. This event is triggered whenever a player sends a message in the chat box.

Implementation

To use the OnPlayerChatted event in Roblox Lua, create a script and insert it into the ServerScriptService or LocalScript service. Here is the basic code skeleton to get you started:

local function onPlayerChatted(player, message)
	-- your code here
end

game.Players.PlayerAdded:Connect(function(player)
	player.Chatted:Connect(function(message) onPlayerChatted(player, message) end)
end)

This script creates a function onPlayerChatted which is called whenever a player sends a chat message. The player object and the message string are passed as parameters.

Reacting to chat messages

Once the chat message is obtained in the onPlayerChatted function, it is possible to perform various actions based on the message content. For example, a simple greeting message when a player joins the game can be implemented like this:

function onPlayerChatted(player, message)
	if message == "/hi" then
		local playerName = player.Name
		game:GetService("Chat"):Chat(game.Players:GetPlayers()[math.random(1,#game.Players:GetPlayers())], string.format("Hi %s!", playerName))
	end
end

This script checks if the chat message is equal to "/hi" and then retrieves the player's name using the player.Name property. The game:GetService("Chat"):Chat method is used to send a message to a random player in the game, greeting the player by name.

Conclusion

The OnPlayerChatted event is an important part of creating Roblox games and experiences. By detecting and reacting to chat messages, it is possible to add interactivity and engagement to the game. With the help of Roblox Lua, the possibilities are limited only by your creativity.
