Script not working on Npc

Help and Feedback Scripting Support
#1

I made a script. The npc is supposed to be invisible and not. It repeats
But the issue is that it’s not working

Here is the script:

local npc = game.Workspace.TeddyAI

while true do
	wait(1)
	npc.Humanoid.Transparency = 0.4
	wait(1)
	npc.Humanoid.Transparency = 1
	wait(1)
	npc.Humanoid.Transparency = 0.4
	wait(1)
	npc.Humanoid.Transparency = 1
	wait(1)
	npc.Humanoid.Transparency = 0.4
	wait(1)
	npc.Humanoid.Transparency = 1
	wait(1)
	npc.Humanoid.Transparency = 0.4
	wait(1)
	npc.Humanoid.Transparency = 1
end

I am a beginner , I took inspirations so don’t expect me to have a correct script.

Try replacing Humanoid with HumanoidRootPart

Use for loops to change every part’s transparency.
Example:

for _, Object in ipairs(NPC:GetChildren()) do
	if Object:IsA("BasePart") then
		Object.Transparency = 0.5
	end
end

This is what it should look like in your script:

local Npc = script.Parent

function ChangeTransparency(Transparency)
	for i, Object in ipairs(Npc:GetChildren()) do
		if Object:IsA("BasePart") then
			Object.Transparency = Transparency
		end
	end
end

while task.wait(1) do
	ChangeTransparency(0.4)
	task.wait(1)
	ChangeTransparency(1)
	task.wait(1)
	ChangeTransparency(0.4)
	task.wait(1)
	ChangeTransparency(0)
end

If you want to use tweens to make it look smooth it’ll look like this:

local Npc = script.Parent
local TweenService = game:GetService("TweenService")
local Speed = 1

function ChangeTransparency(Transparency)
	for i, Object in ipairs(Npc:GetChildren()) do
		if Object:IsA("BasePart") then
			TweenService:Create(Object, TweenInfo.new(Speed), {Transparency = Transparency}):Play()
		end
	end
end

while task.wait(1) do
	ChangeTransparency(1)
	task.wait(1)
	ChangeTransparency(0)
end

These scripts should be parented in the NPC.

If you want to make the NPC invisible, use something that’s called a for loop

What this loop does, is it basically goes through an Array (Or group of objects) and you can check to see if those Objects would be BaseParts

Humanoid Instances don’t have a Transparency property, and additionally you can create a custom Number variable to check how transparent you want to make the NPC

local NPC = workspace:WaitForChild("TeddyAI")
local Visibility = 0 -- 0 is visible, 1 is invisible

while true do
    wait(1)
    if Visibility == 0 then
        Visibility = 1
    else
        Visibility = 0
    end

    for _, Part in pairs(NPC:GetChildren()) do
        if Part:IsA("BasePart") then
            Part.Transparency = Visiblity
        end
    end
end
