Module Script Problems

[noble parcel]

UserInputService.InputBegan:Connect(function(input, processed)
    if input.KeyCode == Enum.KeyCode.B then
        BuildingMode = true

        --// Calling Module Functions

        PlacementHologramModule:HologramPartCreation()
        PlacementHologramModule:HologramPositionMovement(Mouse, BuildingMode)
        task.spawn(function()
            PlacementHologramModule:HologramOrientationMovement(BuildingMode)
        end)
        UserInputService.InputBegan:Connect(function(input, processed)
            if input.UserInputType == Enum.UserInputType.MouseButton1 then
                PlacementHologramModule:HologramPartDestroying()
                BuildingMode = false
            end
        end)
    end
end)

The BuildingMode function only comes up as false within the Module Script before B is pressed, after that it is always set to true for som reason. If you also see any other optimizations possible in my code, let me know as I am quite new.

hi sorry for the ping, so im passing "BuildingMode" as a param to my module script
in this script (not the module), the BuildingMode variable changes as it should (when MouseButton1 is clicked, as seen by the UIS)
however, the BuildingMode variable that is being passed to the module script is not being changed and is set to true after the player has pressed B and doesn't change even when the value of it inside this script changes

sorry if that doesn't make sense, if you tell me what part you dont understand i can clear it up for you

[shy hound]

well yeah, youre just sending it to the module script

the module script cant change variables on another scriñt

script*

the parameter acts as a new value

look into using return

[noble parcel]

no, the value is being changed here in this local script, and the new value is not being passed onto the module scripot

[shy hound]

can we see the module script?

[noble parcel]

i had some debugging prints inside and when

        UserInputService.InputBegan:Connect(function(input, processed)
            if input.UserInputType == Enum.UserInputType.MouseButton1 then
                PlacementHologramModule:HologramPartDestroying()
                BuildingMode = false
            end
        end)

this made the BuildingMode false, there was a print before the if BuildingMode and it printed true after the B key was pressed

sorry i should send as message

function PlacementHologramModule:HologramPositionMovement(Mouse, BuildingMode)
    if BuildingMode then
        Mouse.Move:Connect(function()
            Mouse.TargetFilter = HologramPart
            local Success, Error = pcall(function()
                if Mouse.Target == "Baseplate" or Mouse.Target.Name == "Baseplate" then
                    HologramPart.Parent = game.Workspace
                    local HologramPartPosititonX = math.floor(Mouse.Hit.X)
                    local HologramPartPosititonY = Mouse.Hit.Y + 1
                    local HologramPartPosititonZ = math.floor(Mouse.Hit.Z)
                    local HologramPartPosition = Vector3.new(HologramPartPosititonX, HologramPartPosititonY, HologramPartPosititonZ)
                        
                    --// Tweening Position Change
                        
                    local HologramPartPositionTween = TweenService:Create(HologramPart, HologramPartTweenInfo, {Position = HologramPartPosition})
                    HologramPartPositionTween:Play()
                end
            end)
        end)
    end
end

i'm not sure if it is because the BuildingMode = false is after the param is instantiated inside the module script, that could be a starting point but i'm not very familiar with module scripts

[shy hound]

well yeah thats true

youre always setting it to true

before running the function

if you change the variable in the script it wont change in the module script

because the module script parameter acts as a new variable

[noble parcel]

ohh, is there any way to get around that?

[shy hound]

like any other parameter

[shy hound]

js make a function for setting building mode to false

/true

and call it when you change the variable

[noble parcel]

alright thanks man👍

[noble parcel]

inside the module right?

[shy hound]

ye

[noble parcel]

sorry for the ping but would you know where I can find information on things like dot syntax and colons, init, self and that module stuff because when I look on docs i can't seem to find that stuff

[shy hound]

The . (dot) operator in Lua is used to invoke the method of an object, and it is a widely used operator in Lua. The :(colon) operator in Lua is used when you want to pass an invisible parameter to the method of an object that you are calling.
Self is the object that the method was called on:

apple:Epic()

function apple:Epic()
  --here, self is the "thing" the method was called on, hence apple.
end

--This is the same as

apple.Epic(apple)

function apple.Epic(self)
  --here, we pass the self as a parameter, hence apple.
end

heres some

if you want more info about dot , colon and self: https://docs.coronalabs.com/tutorial/basics/colonDotOperators/index.html

[noble parcel]

yoo thank you so much man, shame that the docs dont say this but that helped a lot man thank you i've just been using colon carelessly 😭

am i blind though or is there like nothing on docs about the other stuff like Init and that stuff in docs?

or is it just the same as external languages so I can learn it from anywhere?

[shy hound]

wdym by init lol

but hu

uh*

you'll probably find it on the lua docs instead

since it isnt luau or roblox-specific

[noble parcel]

i've seen people use stuff like Init in modules

[shy hound]

its just a variable name probably

[noble parcel]

nvm i found a devforum on it, don't worry

[shy hound]

the only thing that it reminds me of is table.find(haystack, needle, init)

where it starts a

oh ok

[noble parcel]

https://devforum.roblox.com/t/what-is-init-in-modules/2033832
yeah its the same as lua u were right

thanks a ton man

[shy hound]

nice
