Unfortunately i did something stupid while making the map and now it's in a non-stop crash. So i had to start all the way back to preview #2. So the full release has been delayed by a long amount of time. Like a month or so. I'm sorry
I know a way to make this way more complicated by using armorstands to recreate the real undertale battles, it's hard though and you'd need a lot of commandblocks for it (your soul is an armor stand wich detects for any other armorstands close to it wich are the blocks, but i won't bother ya with that.
I also got 1 morr simple tip for ya: you can replace bedrock wifh barriers (/give @p minecraft:barrier)
Also when you are done making this, i'd like the texture pack you used for the sounds and try to make an advanced version (of course i'll credit you for the texture pack and undertale for making the music)
I got the barrier and it looks nice, but the /playsound record.mall @p isn't working, as in i can't here anything, if you can, tell me how to fix it. Just a side note, the record does play when put in the jukebox, but not with commandblocks
