"part that follows you and if you dont use a tool to hit it back it kills you"

To create a part that follows a player and can be hit back with a tool, you'll need to write a script that handles the following behavior and the interaction with the tool. Here's an example of how you might script this in Roblox using Lua:

```lua
-- Server Script
local part = Instance.new("Part", workspace)
part.Name = "FollowPart"
part.Size = Vector3.new(2, 2, 2)
part.Position = Vector3.new(0, 3, 0)
part.Anchored = false
part.BrickColor = BrickColor.new("Bright red")

local toolName = "HitTool" -- The name of the tool that can hit the part back

-- Function to make the part follow the nearest player
local function followPlayers()
	while part:IsDescendantOf(workspace) do
		local closestPlayer = nil
		local minDistance = math.huge
		for _, player in pairs(game.Players:GetPlayers()) do
			if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
				local distance = (player.Character.HumanoidRootPart.Position - part.Position).magnitude
				if distance < minDistance then
					closestPlayer = player
					minDistance = distance
				end
			end
		end
		if closestPlayer then
			local targetPosition = closestPlayer.Character.HumanoidRootPart.Position
			local direction = (targetPosition - part.Position).unit
			part.Velocity = direction * 10 -- Adjust the speed as needed
		end
		wait(0.1)
	end
end

-- Function to handle the interaction with the tool
local function onHit(hit)
	if hit.Parent:FindFirstChildWhichIsA("Tool") and hit.Parent.Tool.Name == toolName then
		part.Velocity = -part.Velocity * 2 -- Adjust the force as needed
	end
end

-- Connect the Touched event to the onHit function
part.Touched:Connect(onHit)

-- Start following players
followPlayers()
```

For the part to kill the player if they don't hit it back with the tool, you can modify the `followPlayers` function to include a check that damages the player if the part gets too close:

```lua
-- Add this inside the followPlayers function, within the if closestPlayer then block
if minDistance < 2 then -- Adjust the kill distance as needed
	closestPlayer.Character.Humanoid:TakeDamage(100) -- Adjust the damage as needed
end
```

Please note that this script assumes you have a tool named "HitTool" that players can use to hit the part back. You'll need to create this tool separately and ensure it's available to players in the game.

Remember to adjust the values for speed, force, kill distance, and damage according to your game's requirements. This script should be placed in a Script object within the ServerScriptService or Workspace.
