GetChildren function not working?

Asked by 9 years ago
local Open = false
local Joe = script.Parent.Parent.Close:GetChildren()
local Bob = script.Parent.Parent.Open:GetChildren()

function Click ()
    if Open == false then
        if Joe.name == "Part" then
            Joe.Transparency = 1
            Joe.CanCollide = false
        end
        if Joe.name == "Window" then
            Joe.Transparency = 1
            Joe.CanCollide = false
        if Bob.name == "Part" then
            Bob.Transparency = 0
            Bob.CanCollide = true
        end
        if Bob.name == "Window" then
            Bob.Transparency = 0.5
            Bob.CanCollide = true
        end
        end
        Open = true
    elseif Open == true then
        if Joe.name == "Part" then
            Joe.Transparency = 0
            Joe.CanCollide = true
        end
        if Joe.name == "Window" then
            Joe.Transparency = 0.5
            Joe.CanCollide = true
        end
        if Bob.name == "Part" then
            Bob.Transparency = 1
            Bob.CanCollide = false
        end
        if Bob.name == "Window" then
            Bob.Transparency = 1
            Bob.CanCollide = false
        end
        Open = false
    end
end

script.Parent.ClickDetector.MouseClick:connect (Click)

I click the button and the output shows nothing, this script it also not working, first time trying the GetChildren() function so I hope that's the problem. The function is supposed to find two doors, both having two separate windows in them. When the button is clicked it's supposed to open the door.

The problem here is that the GetChildren function returns a read-only TABLE of the function. You cannot do script.Parent.Parent.Close:GetChildren().Transparency = 1 because it's not that simple. You have to use a for loop to go through each child in Close and perform the action as such.

local Open = false
local Joe = script.Parent.Parent.Close:GetChildren()
local Bob = script.Parent.Parent.Open:GetChildren()

function Click ()
    if Open == false then
        for _, child in pairs(Joe) do --I assume you are familiar with generic for loops
               if child.Name == "Part" then --Capitalize Name, it is the name of a property
                child.Transparency = 1
                child.CanCollide = false
            elseif child.Name == "Window" then --Use elseif instead of multiple if statements
                child.Transparency = 1
                        child.CanCollide = false
            end
        for _, child in pairs(Bob) do
            if child.Name == "Part" then
                child.Transparency = 0
                child.CanCollide = true
            elseif child.Name == "Window" then
                window.Transparency = 0.5
                window.CanCollide = true
        end
    Open = true
    elseif Open == true then
            --You get the point by now
    end
end

script.Parent.ClickDetector.MouseClick:connect (Click)

If you are not familiar with generic for loops, check out this article on the Roblox Wiki for help. If you had any problems understanding these concepts, just ask me and I'll edit my response. I hope my answer was helpful! You can upvote and accept it if you thought so.
