What does ‘add comment’ is for?
In the code

In your code, you can add notes for other people that explain what a certain part of your code is doing. These are called comments.
There are also comments outside of the project, which are used for people to talk to each other, but those are unrelated to the ones in your code, and just have the same name.

Thanks

For example:

go to x: (0) y: (0) //this is a comment

Thank you

Not just for others. If you come back to code you did months or years ago it's easier to understand what's going on if you commented it.

Ok, just sent you a PM, crazy_games_maker, thanks.
