How to use a function when a value "Changes"?

Asked by

So, I made a map loading script, and the problem is that the script, is ment to pick one of the 5 maps randomly, it works, the porblem is that it does it too many times, it's only ment to do it once. Well, I know what to do to fix it, I just don't know how... I mean I know I have to use it as a function, not a while wait.. And I know that theres a way to do the function whenever a value changes... I just don't know how! Help?

RoundStart = game.Workspace.RoundStart
Room1 = game.ServerStorage.Room1
Room2 = game.ServerStorage.Room2
Room3 = game.ServerStorage.Room3
Room4 = game.ServerStorage.Room4
Room5 = game.ServerStorage.Room5

while wait() do
    wait(1)
    if RoundStart.Value == true then
        RandomRoom = (math.random(5))
        if RandomRoom == 1 then
            Map1 = Room1:Clone()
            Map1.Parent = game.Workspace
        end
        if RandomRoom == 2 then
            Map1 = Room2:Clone()
            Map1.Parent = game.Workspace
        end
        if RandomRoom == 3 then
            Map1 = Room3:Clone()
            Map1.Parent = game.Workspace
        end
        if RandomRoom == 4 then
            Map1 = Room4:Clone()
            Map1.Parent = game.Workspace
        end
        if RandomRoom == 5 then
            Map1 = Room5:Clone()
            Map1.Parent = game.Workspace
        end
    end


end

Um what? If you only want it to happen once then don't put it in a loop. Or if you want put it in a function so you can call it multiple times. NotsoPenguin 705 — 9y

Yeah, I know the point is, I want to put it in a function, I just don't know what... Event?.. To use to use that function when the bool value "RoundStart" Changes.. lucas4114 607 — 9y

I think you SHOULD make all of your Map1 =... be a local Map1 alphawolvess 1784 — 9y

The reason it isn't picking random number is because you didn't give it a range, which it requires. So do:

RandomRoom = math.random(1,5) or math.random(5)

also I noticed your script says:

while wait() do
    wait(1)

which isn't necessary, you can just do

while wait() do
--or
while wait(1) do
--the difference is "1" is every second, and () is much faster

NOW TO ANSWER THE MAIN PART OF YOUR QUESTION To connect when a value changes use

game.Workspace.RoundStart.Changed:connect(function()
    --do whatever
end)

You're incorrect in regards to his attempt of picking a random number - math.random(5) would work exactly the same if he did math.random(1,5) - If the random number he wanted wasn't between 1 and 5, but rather 5 and 10, he would need to dictate "a range". DataStore 530 — 9y

Yeah, the random thing DID work for me my way too... lucas4114 607 — 9y
