Roblox Script Generated by ScripterAI

"create a script that changes a mouse cursor when hovered over any NPC inside a folder in workspace called NPCs and you can input a random cursor image. and tell me where to put this script and how to set it up."

To achieve this, you'll need to create a LocalScript inside the StarterPlayerScripts folder. This script will handle changing the mouse cursor when the player's mouse hovers over any NPC inside the NPCs folder in the workspace.

Here's the script:

```lua
-- LocalScript inside StarterPlayerScripts

local Players = game:GetService("Players")
local player = Players.LocalPlayer
local mouse = player:GetMouse()

local npcsFolder = workspace.NPCs

local function onNPCMouseEnter(npc)
    mouse.Icon = "http://www.roblox.com/asset?id=YOUR_CURSOR_IMAGE_ID" -- Replace with your cursor image asset ID
end

local function onNPCMouseLeave(npc)
    mouse.Icon = "" -- Reset the cursor to default
end

local function setupNPCMouseListeners(npc)
    npc.MouseEnter:Connect(function() onNPCMouseEnter(npc) end)
    npc.MouseLeave:Connect(function() onNPCMouseLeave(npc) end)
end

for _, npc in ipairs(npcsFolder:GetChildren()) do
    setupNPCMouseListeners(npc)
end

npcsFolder.ChildAdded:Connect(setupNPCMouseListeners)
```

Replace "YOUR_CURSOR_IMAGE_ID" with the asset ID of the cursor image you want to use.

To set up the script:

1. In the Roblox Studio, click on the "StarterPlayer" object in the Explorer.
2. Right-click on "StarterPlayerScripts" and select "Insert Object" > "LocalScript".
3. Copy and paste the script above into the new LocalScript.
4. Save and test your game.
