My Rock Monster is not Working

Help and Feedback Scripting Support
#1

I want a rock monster to follow the player when they enter a certain area and damage the player when the monster touches the player. Kinda like zombies in zombie attack but with a rock instead. I spent an hour trying to figure out why this error is happening:

Somebody please help, here’s the script:

local char = script.Parent
local humanoid = char:WaitForChild("Humanoid")
local hrp = char:WaitForChild("HumanoidRootPart")

local walkAnim = script:WaitForChild("Walk")
local walkTrack = humanoid.Animator:LoadAnimation(walkAnim)

local dmgAnim = script:WaitForChild("Damage")
local dmgTrack = humanoid.Animator:LoadAnimation(dmgAnim)

local targetPlayer
local dmgAmt = 10

local RunService = game:GetService("RunService")

local triggerPart = workspace.StarterD.Park.Base.RockSpawn

humanoid.Running:Connect(function(speed)
	if speed > 0 then
		if not walkTrack.IsPlaying then
			walkTrack:Play()
		end
	else
		if walkTrack.IsPlaying then
			walkTrack:Stop()
		end
	end
end)

function findNearestPlayer()
	local closestDistance = math.huge
	local touchingParts = triggerPart:GetTouchingParts()
	local plrTouch
	for i, player in pairs(game.Players:GetPlayers()) do
		for i, v in pairs(touchingParts) do
			if game.Players:GetPlayerFromCharacter(v.Parent) then
				plrTouch = true
			end
		end
		local distance = (hrp.Position - player.Character.HumanoidRootPart.Position).Magnitude
		if distance < closestDistance and plrTouch then
			closestDistance = distance
			targetPlayer = player
		end
	end
end

function damagePlayer()
	if targetPlayer then
		local playerHumanoid = targetPlayer.Character:FindFirstChildOfClass("Humanoid")
		if playerHumanoid then
			playerHumanoid:TakeDamage(dmgAmt)
			dmgTrack:Play()
		end
	end
end

RunService.Heartbeat:Connect(function()
	findNearestPlayer()
	if targetPlayer then
		humanoid:MoveTo(targetPlayer.Character.HumanoidRootPart.Position)
		if (hrp.Position - targetPlayer.Character.HumanoidRootPart.Position).Magnitude <= 3 then
			damagePlayer()
		end 
	end
end)

humanoid.Died:Connect(function()
	local newChar = char:Clone()
	newChar.Parent = char.Parent
	char:Destroy()
end)

The script is a little long, hope you dont mind :sweat_smile:

Try to replace player.Character.HumanoidRootPart.Position to player.Character.PrimaryPart.Position,
The primary part of the character should be the HumanoidRootPart.

Also, check if the character exists by adding an if condtion.

if player.Character then
    --Your Script...
end

Now the rock just stays there and doesnt follow the player

Instead of :

try :

local touchingParts = game:GetService("Workspace"):GetPartsInPart(triggerPart)
#5

Nope, still doesn’t work, Should I remove the if plr.Character then that you earlier mentioned?

#6

No need to remove the if plr.Character then, Can you show me what the console says now?

#7

It doesn’t give any output from the script. I dont think there is a plr.Character because there is no error but the rock isn’t following the player.

#8

Update: I used a few print statements and the entire code is working fine but there seems to be a problem with this one line
local distance = (hrp.Position - player.Character:WaitForChild("HumanoidRootPart").Position).Magnitude

#9

You may try :

local hrp = char.PrimaryPart

and replace again :

local distance = (hrp.Position - player.Character.PrimaryPart.Position).Magnitude 
-- Instead of "local distance = (hrp.Position - player.Character:WaitForChild("HumanoidRootPart").Position).Magnitude"
#10

The error says Attempt to index nil with WaitForChild()

Still doesn’t work, no error

#11

Check your Rock Model and make sure that it has a Primary Part, you can set it through the properties :

Note that the primary part should be in the model…

#12

I already checked and yes, it has a primary part and the all the parts except the HumanoidRootPart are not anchored. I also tried using print statements near the .Hearbeat function and I think there’s a problem with humanoid:MoveTo(targetPlayer.Character.HumanoidRootPart.Position)

#13

Oh, because you should not anchor the HumanoidRootPart…

#14

Oh, It works! Thanks! Although the tutorial I used for making custom rigs said you should anchor the HumanoidRootPart :roll_eyes:
