help with voice influenced npc?
I want to make a script where if you are a certain distance away from an NPC, like a maximum of 10 studs, and you say something like hi, it will say hi back. does anyone know how?
I know already how to do the chat
game:GetService("Chat"):Chat(script.Parent.Head, "Hello.", Enum.ChatColor.White)
and i have a door script to like recognize if you chatted
function onChatted(msg, recipient, speaker) local source = string.lower(speaker.Name) msg = string.lower(msg) if (msg == "hi") then

-- First comes our global variables.
local npc = script.Parent
-- Services
local chatService = game:GetService("Chat")
local plrs = game:GetService("Players") -- Define our player service.
-- Variables
local messages =
{
["hi"] = "Hello Player!",
}
--- Functions
function chat(part,msg,color)
chatService:Chat(part,msg,color or Enum.ChatColor.White)
end
function checkMessage(msg)
msg = string.lower(msg) -- lowercase our message
local response = messages[msg]
if response then
chat(npc.Head,response)
end
end
function playerAdded(plr) -- Define our function for when players join.
plr.Chatted:Connect(function(message,reciever)
if plr.Character then -- Check if the player has a character
if not reciever then -- Make sure it isn't a private message.
local plrPos= plr.Character:GetPrimaryPartCFrame().p
local npcPos = npc:GetPrimaryPartCFrame().p
local distance = (plrPos-npcPos).magnitude -- Define the distance from the character to our NPC.
if distance < 10 then
wait(1)
checkMessage(message)
end
end
end
end)

Hello Xeilot,
First, let's define a chat function for you to use:
local chatService = game:GetService("Chat")
function chat(part,msg,color)
chatService:Chat(part,msg,color or Enum.ChatColor.White)
end
This allows you to make any part you want chat. We define the chat service outside of the function so we don't have to get it every time we use the function.
After that, we'll create a checkMessage function to check valid messages, and have the NPC reply.
local messages =
{
["player message here"] = "NPC Response here",
}
function checkMessage(msg)
msg = string.lower(msg) -- lowercase our message
local response = messages[msg]
if response then
chat(npc.Head,response)
end
end
Next, we need to check for player chats. This one is a bit more tricky, but overall pretty easy.
local plrs = game:GetService("Players") -- Define our player service.
function playerAdded(plr) -- Define our function for when players join.
end
plrs.PlayerAdded:Connect(playerAdded)
Inside that function we can check when a player has chatted.
local plrs = game:GetService("Players") -- Define our player service.
function playerAdded(plr) -- Define our function for when players join.
plr.Chatted:Connect(function(message,reciever)
if plr.Character then -- Check if the player has a character
if not reciever then -- Make sure it isn't a private message.
local distance = (plr.Character:GetPrimaryPartCFrame().p-npc:GetPrimaryPartCFrame.p) -- Define the distance from the character to our NPC.
if distance < 10 then
checkMessage(message)
end
end
end
end
end
plrs.PlayerAdded:Connect(playerAdded)
Now that we have those three components, let's define our NPC.
local npc = script.Parent -- Change this if your script is in a different place.
We're done! Now we can combine it into one script:
-- First comes our global variables.
-- Services
local chatService = game:GetService("Chat")
local plrs = game:GetService("Players") -- Define our player service.
-- Variables
local messages =
{
["player message here"] = "NPC Response here",
}
--- Functions
function chat(part,msg,color)
chatService:Chat(part,msg,color or Enum.ChatColor.White)
end
function checkMessage(msg)
msg = string.lower(msg) -- lowercase our message
local response = messages[msg]
if response then
chat(npc.Head,response)
end
end
function playerAdded(plr) -- Define our function for when players join.
plr.Chatted:Connect(function(message,reciever)
if plr.Character then -- Check if the player has a character
if not reciever then -- Make sure it isn't a private message.
local plrPos= plr.Character:GetPrimaryPartCFrame().p
local npcPos = npc:GetPrimaryPartCFrame().p
local distance = (plrPos-npcPos).magnitude -- Define the distance from the character to our NPC.
if distance < 10 then
checkMessage(message)
end
end
end
end
end
-- Event listeners
plrs.PlayerAdded:Connect(playerAdded)
And we're done! The NPC now can detect when a player chats, check the distance between it and the player, and then reply!
If you've got any questions, feel free to ask me.
