How do I fix this if then statement?
So this if then statement is supposed to detect a certain value. However, I want it to do something else when the value changes.
01 | local Hit = script:waitforchild("Random") |
02 |
03 | while wait() do |
04 | if Hit.Value == true then |
05 | print('Hi') |
06 | end |
07 | if Hit.Value == false then |
08 | print('Goodbye') |
09 | end |
10 | end |
I want the script to do something else once the value changes. How would I make the script do this? Can someone please help me?

It is suppost to be WaitForChild. Caps do matter in Lua. woodengop 1134 — 10y

Continent is correct, you should be using WaitForChild and not waitforchild.
To catch when an Value object is changed, use the Changed event. You can also make that if statement more efficient by using else instead of a second if!
1 | local Hit = script:WaitForChild("Random") |
2 |
3 | Hit.Changed:connect(function() |
4 | if Hit.Value == true then --the `== true` can be omitted here, since `if true == true then` --> `if true then` |
5 | print("Hi") |
6 | else --If it's not true, it must be false! |
7 | print("Goodbye") |
8 | end |
9 | end) |
If you want to add more variables to check:
01 | local Hit = script:WaitForChild("Random") |
02 |
03 | Hit.Changed:connect(function() |
04 | if Hit.Value and someOtherValue.Value then |
05 | print("Hi -- someOtherValue is true!") |
06 | elseif Hit.Value then |
07 | print("Goodbye -- someOtherValue is false!") |
08 | else |
09 | print("someOtherValue is unknown!") |
10 | end |
11 |
12 | --or, just add another `if` tree: |
13 |
14 | if someThirdValue.Value then |
15 | print(1) |
16 | else |
17 | print(2) |
18 | end |
19 | end) |

Let's say there were two variables involved, how would I get that to work? Would I have another ".Changed:Connect(function()" line? CoolJohnnyboy 121 — 10y

No need! You can simply add more `if` trees inside the connected function. I'll edit my answer to include an example. adark 5487 — 10y
