How To Add Breadcrumbs To Custom Layout?

Hi, so I have a custom dispatch and custom tpl files that are working, for some reason. I also made a custom layout, and other blocks work there. But when I add the breadcrumb block it doesn't seem to appear.

I think I have to use the fn_add_breadcrumb function in the php controller file in order to add a node so that it will appear in the layout, but I'm not quite sure how the parameters of the function work or what the process is for using it. Can anyone help me?

Nevermind, I got it to work haha.
