Checking if a variable changed

Help and Feedback Scripting Support
#1

Basically, i have a setTime like 4 secs or smth. what i want to do is to wait for setTime's value such as wait for 4 secs. Then do sum stuff. Iam facing an issue tho.

I am using an if statement to check if a variable is tru or not and if it is it runs the wait(setTime) line. But i want to break the if statement value is changed mid-waiting.

So is there any better way to wait other than using the wait(). And also how do i check if the var is changed?

Code:

UserInputService.InputBegan:Connect(function(inputObject)
	if inputObject.UserInputType == Enum.UserInputType.MouseButton1 then
        breaking = true
        local secs = 4 --time to wait
	       if breaking then
	           wait(secs)
		      --do stuff here
end)

UserInputService.InputEnded:Connect(function(inputObject)
	if inputObject.UserInputType == Enum.UserInputType.MouseButton1 then
		breaking = false
end)

You could just check if the condition is still true after the waiting time.

breaking = true
task.wait(4)
if breaking then
     -- do stuff
end

But will it work, lets say while iam like 0.007 secs into breaking the block and then i leave my leftmousebtn. Will it still check?

#4

yes because the variable being checked is global (outside the connection).
So if it changes before the wait time is up, when you re-check for the variable it will see that it is false and not true.

#5

why task.wait tho?Can u explain the use of it? why use it instead of putting wait in the if statement?

#6

And also i want to wait inside the if statement thts y i asked if there is a diferrent way to do it.

Task Library

Eventually I think wait() will become deprecated for this instead. I suggest using task.wait() in the future.

#8

What iam trying to say is that i want to count from the time like 4 secs, if mid counting the var changed i want to break the if satatement? Any solutions?

#9

I would just do what @Dev_Ryan said. I thought you already had your solution.

You could do a while true do loop and check while breaking is true do your code, then break at the very end so it doesn’t repeat.

#10

Nvm abt the wait issue i solved it but it still doesnt stop the if statement even tho breaking is false.

#11

InputBegan:

if input.UserInputType == Enum.UserInputType.MouseButton1 then
	if not breaking then
		breaking = true
		local timeSpent = 0
		repeat
			timeSpent += 1
			task.wait(1)
		until not breaking or timeSpent >= 4
		if timespent >= 4 then
			-- do stuff
		end
	end
end

InputEnded:

if input.UserInputType == Enum.UserInputType.MouseButton1 then
	breaking = false
end
#12

use heartbeat increase your timer there. you can check breaking statement with every iteration. It is also
more performant against using tasks

#13

For checking the variable changed you could just make a value somewhere and maybe use this:

coroutine.wrap(function()
while wait() do
[value].Value = variable
[value]:GetPropertyChangedSignal(“Value”):Connect(function()
–code
end)
end
end)()

My opinion is that it’s very simple and effective!
