"make me a script tha tmakes that when a player is nearby this npc the npc gets closer to him and when the npc touches th eplayer the player g ets damaged and the npc plays an animation when damaging the player"

Sure, here's a script that does that. You'll need to insert this script into the NPC's humanoid:

```lua
local humanoid = script.Parent
local root = humanoid.Parent.PrimaryPart
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local damageAmount = 10
local attackAnimationId = "rbxassetid://1234567890" -- replace with your animation ID

-- Create the attack animation
local attackAnimation = Instance.new("Animation")
attackAnimation.AnimationId = attackAnimationId
local attackTrack = humanoid:LoadAnimation(attackAnimation)

-- Function to find the nearest player
function findNearestPlayer()
	local playerList = Players:GetPlayers()
	local nearestPlayer = nil
	local distance = nil
	local direction = nil 
	
	for _, player in pairs(playerList) do
		local character = player.Character
		if character then
			local distanceVector = character.PrimaryPart.Position - root.Position
			if not nearestPlayer then
				nearestPlayer = player
				distance = distanceVector.Magnitude
				direction = distanceVector.Unit
			elseif distanceVector.Magnitude < distance then
				nearestPlayer = player
				distance = distanceVector.Magnitude
				direction = distanceVector.Unit
			end
		end
	end
	
	return nearestPlayer, distance, direction
end

-- Function to damage a player
function damagePlayer(player)
	local character = player.Character
	if character and character:FindFirstChild("Humanoid") then
		character.Humanoid.Health = character.Humanoid.Health - damageAmount
	end
end

-- Connect to the RunService heartbeat event
RunService.Heartbeat:Connect(function()
	local nearestPlayer, distance, direction = findNearestPlayer()
	if nearestPlayer and distance < 10 then -- replace with your desired distance
		humanoid:Move(direction)
		if distance < 2 then -- replace with your desired touch distance
			damagePlayer(nearestPlayer)
			attackTrack:Play()
		end
	end
end)
```

This script will make the NPC move towards the nearest player if they are within a certain distance. When the NPC touches the player, it will damage the player and play an attack animation. You'll need to replace the `attackAnimationId` with the asset ID of your attack animation. You can also adjust the `damageAmount`, `distance`, and `touch distance` to fit your needs.
