wordpress/buddypress uses the template file ( ie footer.php ) in the child theme directory if it exists, otherwise it uses the parent’s file.
*.php files are simple text files and normally everything means something. Most things have opening and closing tags which you need to be aware of, but in general, what you put in the child theme’s file will then be used…
functions.php and style.css are loaded after the parent theme’s versions.
The only file a child theme needs is a style.css which will overwrite rules in the parent’s css
