Help with a value checker

Help and Feedback Scripting Support
#1

How do I make a function that constantly checks until a value is true? Then if the value is true it does something.

#2

Sounds like you want a while loop. Here is a code example below:

ValueIsTrue = false   

function TrueCheck()
     
    While ValueIsTrue == false do
        task.wait()
    end

    -- Add code here for when value is true
end

TrueCheck()

More info on while loops can be found here: Introduction to Scripting | Roblox Creator Documentation

#3 
repeat
task.wait(0.5) --you can change this on how often it checks
until ThisValue == true

--Code to run after it's true.
#4

This would enable a script timeout and kill the script. There needs to be a task.wait() inside the loop. This will run a million times instantly without the task.wait().

I see you added wait() to your script. This should be task.wait() because wait() is being deprecated.

#6

Saying this value is an instance or an attribute there are appropriate events for them, you can check on their respective page.

If this is regarding a variable, you would so something like

local RunService = game:GetService("RunService")
local Variable = False
task.spawn(function()
   while not Variable do
       RunService.Heartbeat:Wait() -- you can also task.wait()
   end
   --your code to run here
end)

Reason for spawning is not stopping the whole code when waiting for it to change.

Thanks for letting me know! I found the post about task.wait().

Shouldn’t you use a changed event instead?

OP did not specify if it was a variable or an instance value.

wouldn’t a while true loop work best?

OP didn’t specify if it was an IntValue or a variable.
