I am currently working on a custom modular factory system where it’s purpose is every “tick” it calls the function :TransferItems() now this function is required to check if the next machine has a “inDirection” attachment that has to face the same way as the “outDirection” on the current.
For some reason it gives me wild lookvectors and acts strangely.
I can see on the Axis property of them that one of them is -1,0,0 and the other is 1,0,0 but they are facing the same way?
and the other difference is that when I try to change the Axis to be the same as the current one, it makes the rotation in the Y axis to 180 while making it face the wrong way.
Now I do know that they might be facing a weird way already, but for some reason it worked rotating them 45 when I was making the object checking system to check if the conveyor was infront of the DropoffZone belt
My system works with a FactoryManager that holds all players factories, while scripts can add other machines to it which it runs the :TransferItems() and :ProcessItems() functions.
So in short what im trying to do is check if both lookvectors are the same, but they are supposed to be the same but isn’t.
It could be because attachments have both a CFrame property, as well as a WorldCFrame property.
Could you post some code snippets - but my first though would be to use WorldCFrame rather than CFrame (assuming you are currently using CFrame)
Something like
attachment.WorldCFrame.lookVector
Yes alright, the system I have been working on has individual modulescripts for each machine / belt and one modulescript for the FactoryManager. This code is from the DropoffZone belt modulescript.
-- On creation of this object
function DropoffZone.new(object)
local self = setmetatable({}, DropoffZone)
self.object = object
self.PrimaryPart = object.PrimaryPart
self.items = {} -- items currently in the drop-off zone
return self
end
-- inside :transferItems(factoryManager, userId)
-- Check if the DropoffZone has a PrimaryPart
if not self.PrimaryPart then
warn("DropoffZone does not have a PrimaryPart")
return nil
end
-- Check for a connected machine
--[[for _, machine in pairs(factoryManager.machines) do
if machine ~= self and machine.PrimaryPart then
local endPosition = attachment.WorldPosition + attachment.WorldCFrame.LookVector * 3 -- Assuming 3 units long zone
local machineAttachment = machine.PrimaryPart:FindFirstChild("Attachment")
if machineAttachment and (machineAttachment.WorldPosition - endPosition).Magnitude <= 1 then
return machine
end
end
end]]
-- Check for a connected belt
for _, belt in pairs(factoryManager.belts) do
if belt ~= self and belt.PrimaryPart then
--warn("DEBUG DROPOFFZONE")
--print(belt.object)
--print(belt.PrimaryPart.Position)
local isCorrectObject = false
local isAllowed = false
local selfOuts = {}
local selfIns = {}
local beltOuts = {}
local beltIns = {}
for _,att in pairs(self.PrimaryPart:GetChildren()) do
if not att:IsA("Attachment") then
continue
end
if att.Name == "inDirection" then
table.insert(selfIns, att)
end
if att.Name == "outDirection" then
table.insert(selfOuts, att)
end
end
for _,att in pairs(belt.PrimaryPart:GetChildren()) do
if not att:IsA("Attachment") then
continue
end
if att.Name == "inDirection" then
table.insert(beltIns, att)
end
if att.Name == "outDirection" then
table.insert(beltOuts, att)
end
end
if #beltIns == 0 then
continue
end
local chosenNum
local chosenAtt
if #selfOuts > 1 then
chosenNum = math.random(1,#selfOuts)
chosenAtt = selfOuts[chosenNum]
else
chosenAtt = selfOuts[1]
end
if not chosenAtt then
continue
end
local endPosition = chosenAtt.WorldPosition + chosenAtt.WorldCFrame.LookVector * 3 -- Assuming 3 units long zone
local chosenInAtt
for i,v in pairs(beltIns) do
print(v)
print(v.WorldCFrame.LookVector)
print(chosenAtt.WorldCFrame.LookVector)
if v.WorldCFrame.LookVector == chosenAtt.WorldCFrame.LookVector then
print("is allowed!!")
chosenInAtt = v
isAllowed = true
end
end
if chosenInAtt == nil then continue end
print(chosenInAtt)
local distance = (chosenInAtt.WorldPosition - endPosition).Magnitude
--print(beltAttachment.WorldCFrame.LookVector)
debugObject(endPosition)
--warn(distance)
if chosenInAtt and distance <= 1 then
isCorrectObject = true
print("IS WITHIN REACH")
--print(distance)
return belt
end
print(isAllowed)
print(isCorrectObject)
if isAllowed and isCorrectObject then
warn("IS GOOD!")
return belt
end
--warn("--------------------------")
end
end
return nil
This is quite a complex project for me apologies if its got stuff in it that’s not being used.
It can have both in and out attachments or only one of them depending on the machine / belt
Little update to the post, I figured out that it would not cause the issue when I placed it, but the moment I left the game and rejoined and that is when my data loaded back up again.
