I think the Ambient Block could do with even more sounds. NPC sounds like the Werewolf, Dryad, Orc, Spider could be great additions to the Ambient Block. On top of that idea why not short music pieces that are combinable to an extent you could make your own music in the game? All these thing could possibly add alot of options to players.
#More sounds for the Ambient Block and maybe more
golden eagle
harsh bane
Also to be able to locally play a sound on a player without his coordinate would be great
wooden pebble
I agree with this post, I think there should be more sounds. For example if a map maker wanted to script a door that slides open/closed, it would be useful to have a sliding door open/close sound that plays to give the illusion that the door is actually sliding open or closed.
