Setting current page class in a loop of post names

Hello,
Can anyone help me with this or give me some advice?

I have a loop that is listing all the names of a custom post type in a certain category linking to their specific page (creating a menu). I’m trying to figure out a way, in the loop to set a class of “current” to one of the names when you’re on that page.

Something like this, but I want it to add it to one item in the loop for the current page, whatever that may be.
if ( is_single( "post_name" ) ) { echo ' class="current_page_item" '; }

I can probably just create a menu of the posts, but I wanted this to be dynamic so when a post is created it automatically gets added to the menu.

My loops is working fine to list all the post names, but I just want that class “current” to get added to the one you’re on.

Any help is appreciated.
