Are their anyways of making a timer going on while a script is going on?

There are a couple.

I don't know why you would want to use any of these other methods, but I'll go over them anyways.

• First Method,

The first idea is using the Delay Function. Here's the link to the wiki page about the delay function. An example would look like this,

script.Parent.Touched:connect(function(part)
    delay(1,function()
        part:Destroy()
    end)
end)

Here's a short gif of this script in action.

• Second Method,

Another is to use the Spawn Function. This works similarly to the first method, but you can't pass the amount of time you want to wait into the function. This can easily be done with a wait, but it's worth noting.

script.Parent.Touched:connect(function(part)
    spawn(function()
        wait(1)
        part:Destroy()
    end)
end)

I hope that gives you some insight, and that this answer was what you wanted.

Good Luck!

If I helped, please don't forget to accept my answer!

I have not used this function personally, but from what I've read on the wiki, delay is what you are looking for. Use it like this:

delay(time, func)

Where time is the time in seconds and func is the function to run.
