Epic Boss Music

In the mob procedure section, you can have a procedure that executes when the mob first spawns.  For your procedure, you can find the play sound block in the world management section.  However, I don't know if there is a way to stop or replay your music once the boss is killed, or if they aren't killed yet.

Oh, you also have to go to resources/sound files and import your epic boss music.

Here's how one could use boss music when it comes to mobs, both start and stop.

On initial mob spawn
- Use this block:

Play at X:(x) Y:(y) Z:(z) level:(Num) pitch:(Num) sound:(Sound)

 If it's a custom sound, I believe the sound is played based on what category it is in, such as master, ambient, player, neutral, hostile, block, record, and music.

When mob dies
- There's not necessarily an official stopsound block, however you could use this block:

Execute command /

 and use this command:

stopsound @a <sound category> <sound>

This should work for what you want to have happen, but I could be wrong.

oh my god thats useful for me too

How i Put the block in initial mob spawn

its not a block its a trigger in the mob mod element

how do i make the music loop? Since it just stops at one point

first, you have to know how many seconds long your song is. in minecraft, one second = 20 ticks, so multiply the song length in seconds by 20, so <song length> × 20.

heres an example:

song length = 3:21 minutes ÷ 60 = 201 seconds

201 seconds × 20 = 4020 ticks

now you know how many ticks your song plays for, so you can now use the [wait <ticks> , then on server-side:] block to trigger the song again. you should also put an if-statement to check if the boss is still alive.
