Source URL’S can get pretty long and may need replacement. Luckily, you can shorten them into aliases. This is like a shortcut for any given source.
To start, you need to define an alias, for this example, we’ll make a sound called test
/openaudio alias test https://craftmend.com/mysound.mp3`
This means that every time we write a:test, we actually mean https://craftmend.com/mysound.mp3. You can use this alias as a source everywhere, regions, speakers, traincarts signs, play commands, you name it. Such an example play command is
/openaudio play @a a:test
