Multiple part moving from point A to point B, at a random rate

Hello !

I’m working on an obby stage, and I want that my part (called “log”) come from the left, and move to the right, so people can jump on it to go through the stage.

But only 1 part will be long and boring, so I want that there is a random amount of part going through.

I know I should use Tween Service, but when I put multiple part, they all go through at once, then there is nothing for a few second, until they all comeback.

Sorry if my english isn’t perfect, and sorry if you can’t understand what I try to say, I don’t know how to explain :confused:

You can use coroutine in that case. From what your explanation says about what you want to achieve, this probably is the best option.

Thank you, but I don’t know how to do that. I will continue reading the coroutine.
