Im trying to make a minigame that only have 1 map for now and its speed run. The problem is it keeps saying a nil value until I have no idea. So I need a help here. Here is the dev console : [I use a link because I can't put my screenshot here by using trello] https://trello.com/c/owZ7gkSZ/27-a-nil-value-problem-screenshot

And the script :

01--start

04--variables
05Map1 = game.ServerStorage.Maps.Arena1
06NotificationBoard = game.Workspace.StatusBar.Text

Line 2 - It's not gonna work that way, You gotta bind a function to player added event buoyantair 123 — 9y

The problem is the line 61. See the dev console screenshot krisxxxz 45 — 9y

Anyway thanks for that tips. Because I just noticed that line 2 is a bit weird and glitchy before I edit the script into the script you see now. krisxxxz 45 — 9y

As I see it, your script is flawed that, even if we do give an answer... it will not work with the rest of your coding... as such, i suggest you try to make it so that everything is coherent... for example:

The map is still in ServerStorage, to move it you should use:

1local mapholder = Instance.new("Model", game.Workspace)
2mapholder.Name = "CurrentMap"
3 
4game.ServerStorage.Maps.Arena --[[ error ]]

Your map will now error because the map has a NumberValue in a line of code that has a String, as such you will need to use FindFirstChild()

1local mapholder = Instance.new("Model", game.Workspace)
2mapholder.Name = "CurrentMap"
3 
4local mapa = game.ServerStorage.Maps:FindFirstChild("Arena1")
5mapa.Parent = mapholder

I could keep going on, but I will instead recommend you to some ROBLOX wiki pages that you should learn:

http://wiki.roblox.com/index.php?title=Loops

http://wiki.roblox.com/index.php?title=Function_dump/Basic_functions&redirect=no#pairs

http://wiki.roblox.com/index.php?title=API:Class/Instance/FindFirstChild

After you have done this, you should start from scratch, and attempt to create a smooth code.. if you still cannot do this, pm me on roblox (Username: Taryo)

Edit:

Removed CFrame and Vector3 from recommended list, you can still view them here:

Thanks alot for the help. krisxxxz 45 — 9y

You're welcome... The issue was that even though some of your code worked... it wouldn't work with the rest of your code. I recommended you to some places, but also make sure to review functions here: http://wiki.roblox.com/index.php?title=Function Scarious 243 — 9y

And why do you give me about CFrames and vector 3? Is it about the teleporter? The teleporter doesn't work? Cause Im a bit confused that you give me that:/ krisxxxz 45 — 9y

Oops, I didn't mean to add CFrame to that list, that was for another person, also I added Vector3 because it is typically best to use them inside of CFrame. perhaps since I was thinking of CFrame I added it to the list? I'll edit it. Scarious 243 — 9y

oh ok. Thanks for editing it. krisxxxz 45 — 9y

And, I almost forget to ask you about the teleporter, about the Reciver Variable cause it look a bit weird and I have a bad feeling about it. krisxxxz 45 — 9y
