"make a npc script that moves to a random spot and able to jump and talk randomly along with not being able to fall off the map also make the npc have ai that can respond to other players and dont use comments"

Creating such a complex NPC would require a large amount of code and would be quite complex. However, I can provide you with a basic example of how you might start creating such an NPC.

```lua
local PathfindingService = game:GetService("PathfindingService")
local Players = game:GetService("Players")
local npc = script.Parent
local humanoid = npc.Humanoid
local rootPart = npc.HumanoidRootPart

local function moveToRandomLocation()
    local randomX = math.random(-500, 500)
    local randomZ = math.random(-500, 500)
    local targetPosition = Vector3.new(randomX, 0, randomZ)
    local path = PathfindingService:CreatePath()
    path:ComputeAsync(rootPart.Position, targetPosition)
    local waypoints = path:GetWaypoints()
    for _, waypoint in ipairs(waypoints) do
        humanoid:MoveTo(waypoint.Position)
        if waypoint.Action == Enum.PathWaypointAction.Jump then
            humanoid.Jump = true
        end
        humanoid.MoveToFinished:Wait()
    end
end

local function talkRandomly()
    local phrases = {"Hello!", "How are you?", "Nice weather we're having."}
    local randomPhrase = phrases[math.random(#phrases)]
    npc.Chat:Chat(npc.Head, randomPhrase, "SayMessage")
end

local function respondToPlayer(player)
    local phrases = {"Hi, " .. player.Name .. "!", "Nice to meet you, " .. player.Name .. "!", "How's it going, " .. player.Name .. "?"}
    local randomPhrase = phrases[math.random(#phrases)]
    npc.Chat:Chat(npc.Head, randomPhrase, "SayMessage")
end

Players.PlayerAdded:Connect(function(player)
    player.Chatted:Connect(function()
        respondToPlayer(player)
    end)
end)

while true do
    moveToRandomLocation()
    talkRandomly()
    wait(5)
end
```

This script will make the NPC move to a random location on the map, jump when necessary, and chat random phrases. The NPC will also respond to players when they chat. However, this script does not prevent the NPC from falling off the map, and it does not give the NPC advanced AI capabilities. Those features would require much more complex scripting.
