Weld not a valid member even though it is

Help and Feedback Scripting Support
#1

Hello!

I’m attempting to make a script where it finds a random part and deletes it’s welds. The issue is, it states that Weld is not a valid member, even though it does exist. I tried to put a WaitForChild, but it infinite yielded. Other posts weren’t relevant or didn’t work. Any help is appreciated!

local Model = workspace.Grassland

local function DeleteRandomPart()
	local ChildrenOfModel = Model:GetChildren()
	local PartToDelete = ChildrenOfModel[math.random(#ChildrenOfModel)]
	local Weld = PartToDelete:WaitForChild("Weld")
	if Weld then
		if PartToDelete.Name == "LandPart" then
			Weld:Destroy()
		end
	end
end

for count = 1, #Model:GetChildren() do 
	DeleteRandomPart()
	wait(.1)

	if not #Model:GetChildren() then
		Model:Destroy()
		break
	end
end
#2

Try

local Weld = PartToDelete:FindFirstChildOfClass("Weld")
if Weld and PartToDelete.Name == "LandPart" then
	Weld:Destroy()
end
#3

Didn’t work, in fact broke the whole script.

#4

Are there any errors in the output?

#5

No errors, the script somehow stopped.

#6

Your script iterates all children of the model. If not all parts of the model have welds or are named “LandPart” then the script will just skip over them with a 0.1 second wait. Try removing the wait(.1) and see if it breaks all welds

#7

Nothing’s happening. I only want the script to break the welds of certain parts.

local Model = workspace.Grassland

local function DeleteRandomPart()
	local ChildrenOfModel = Model:GetChildren()
	local PartToDelete = ChildrenOfModel[math.random(#ChildrenOfModel)]
	local Weld = PartToDelete:FindFirstChildOfClass("Weld")
	if Weld and PartToDelete.Name == "LandPart" then
		Weld:Destroy()
	end
end

for count = 1, #Model:GetChildren() do --repeats the line below for the number of children in the model
	DeleteRandomPart()
	wait(1)

	if not #Model:GetChildren() then
		Model:Destroy()
		break
	end
end
#8

You could try something like this

local Model = workspace.Grassland
local Parts = {}

-- store all parts named LandPart in array
for i, Part in pairs(Model:GetChildren()) do
	if Part.Name == "LandPart" then
		table.insert(Parts, Part)
	end
end

-- delete part from the array of stored parts
local function DeleteRandomPart()
	local PartToDelete = table.remove(Parts, math.random(#Parts))
	local Weld = PartToDelete:FindFirstChildOfClass("Weld")
	if Weld then
		Weld:Destroy()
	end
end

for i = 1, #Parts do
	DeleteRandomPart()
	if #Parts <= 0 then
		Model:Destroy()
		break
	end
	wait()
end
#9

Nope, nothing. No errors at all.

#10

Can you show the hierarchy of “Grassland” and the parts and welds inside?

#11

Screenshot (3)

That’s only a portion of the model, it’s the same thing

#12

Okay try this and lmk what it says in the output

local Model = workspace.Grassland
local Parts = {}

-- store all parts named LandPart in array
for i, Part in pairs(Model:GetChildren()) do
	if Part.Name == "LandPart" then
		table.insert(Parts, Part)
	end
end

print("Number of parts:", #Parts)

-- delete part from the array of stored parts
local function DeleteRandomPart()
	local PartToDelete = table.remove(Parts, math.random(#Parts))
	local Weld = PartToDelete:FindFirstChildOfClass("Weld")
	if Weld then
		Weld:Destroy()
		print'Destroyed Weld'
	end
end

for i = 1, #Parts do
	DeleteRandomPart()
	if #Parts <= 0 then
		Model:Destroy()
		print'Destroyed Model'
		break
	end
	wait(0.2)
end
#13

Number of parts: 323 (((((((((((((((((((((((((

#14

Does it print “Destroyed Weld”? Maybe it just takes a while for you to notice it deleting any welds since it’s 323 parts

#15

It sayd “Destroyed Weld” even though the welds are still there.

#16

With wait(0.2) it would take 64.6+ seconds to delete all welds, are you sure it’s not deleting any welds at all?

#17

When it said “Destroyed Weld”, the welds were still there. I waited a few more seconds, welds weren’t deleted.

#18

If this is what I think it is, you can do a for loop to delete the welds of a random part

for _,v in pairs(randompart:GetChildren()) do
if v:IsA(“Weld”) then
v:Destroy()
end
end)

#19

Nope, didn’t work either. Only the original script works?

#20

It’s deleting the welds fine for me. Remove the wait() completely and see if the welds are still there
