How to make everything invisible expect things that contain Humanoid?

[NoobyRequiem]

		local Chars = {}
		for _, Humanoid in ipairs(game.Workspace:GetDescendants()) do
			if Humanoid:IsA("Humanoid") then
				table.insert(Chars, Humanoid.Parent)
			end
		end

		for i,v in pairs(game.Workspace:GetDescendants()) do
			for i,char in pairs(Chars) do
				if v:IsA("Part") or v:IsA("Texture") or v:IsA("Decal") or v:IsA("SpawnLocation") then
					if v:IsDescendantOf(char) then
					else
						task.spawn(function()
							originTransparency[v] = v.Transparency
							game.TweenService:Create(v,TweenInfo.new(0.5),{Transparency = 1}):Play()
						end)
					end  
				end
			end
		end

This will work

local tween = game:GetService("TweenService")
local plrs = game.Players

local function checkifplayer(plrlist,v)
	local IsDescendantOfPlayer = false
	for _,plr in pairs(plrlist) do
		if v:IsDescendantOf(plr.Character) then IsDescendantOfPlayer = true end
	end
	return IsDescendantOfPlayer
end

local function FadeAllExceptPlayer()
	local PlayerTable = plrs:GetPlayers()
	for _,v in pairs(workspace:GetDescendants()) do
		if (v:IsA("Part") or v:IsA("MeshPart")) and not checkifplayer(PlayerTable,v) then
			tween:Create(v,TweenInfo.new(1,Enum.EasingStyle.Quad,Enum.EasingDirection.InOut),{Transparency=1}):Play()
		end
	end
end

task.wait(5)
FadeAllExceptPlayer()

Edit: This will only fade all parts and meshparts considering that’s mainly we use, if you want more you can add more v:IsA(“”)s to the if statement or just do a pcall to check if the part has property “Transparency”, details below:
Check if object has certain property

Intended or not, this just detects if the instance is part of a player character, and not all humanoids.

local TweenService = game:GetService("TweenService")

local Info = TweenInfo.new(0.5)

local function ApplyTween(instance)
    TweenService:Create(instance, Info, {Transparency = 1}):Play()
end

for _, v in workspace:GetDescendants() do
    if not v:IsA('BasePart') then
        continue
    end
    
    local Character = v:FindFirstAncestorWhichIsA('Model')

    if not Character then
        ApplyTween(v)
        continue
    end

    local Humanoid = Character:FindFirstChildWhichIsA('Humanoid')

    if Humanoid then
       continue
    end

    ApplyTween(v)
end

What do you mean by this? I think my script do check if the part or meshpart is a descendant of any player character, though it do ignore npc humanoids

@soprosostupid

though it do ignore npc humanoids

yeah thats my point, the op says that he wants everything to be invinsible, except for things that contain humanoid, not just players

[soprosostupid (carbonsoda)]

My bad. Also I think you may have to make the meshids of meshparts to “” so it’s actually invisible. Though how to restore them is another thing.

Btw,

@Artzified

for _, v in workspace:GetDescendants() do

I think you missed in pairs? nvm, I never knew that!

Anyways thanks a lot! Have been searching for an effective method to check this.

No, it works fine, I’ve heard that its actually better to not use any iterator functions
