Schematic export must be rewritten to support 1.13+

[Andrew-J-Larson]

When exporting a song, it works fine, however... with how Minecraft works, if you have a large enough song, some note blocks have sand and gravel, but are in the air... When playing the song, the sand or gravel (or any other gravity following block) will fall after the note block plays.

The fix? Include a solid block under any blocks that can fall.

Also, here's a schematic to test... it has some sand that will fall as soon as a note block is played (in the zip).

Are you sure there is always room for a block below the gravel/sand?

[Andrew-J-Larson]

Actually I'm not entirely sure, but I'm sure a check to see if a block is underneath it could be done, to prevent replacing another noteblock.

I have encountered similar problems.
Most of the time, there is a block of space under the sand and each time the note box is activated, it falls onto another note box.

[HielkeMinecraft]

Placing a block under the sand or gravel won't be a solution. When working with multiple layers, there are note blocks under the top ones. So placing a support block under the top ones would mute the lower note block's sound.

As you can see here: (bedrock = support)

This issue used to be not a problem, because clay would make the same sound as gravel/sand. But alas, here we are.

Only way to fix this is to write it in the note block's block state. This does persist after being powered by redstone, but it will reset when the block under it is broken. Not bad.

2 problems with this approach.

• Minecraft
  You can't store instrument type before Minecraft 1.13. So <1.13 you must set the block below the note block.
  We can fix this by just using clay when using Minecraft 1.12 and below.

• The .schematic format
  This format hasn't been updated in years, so it won't save stuff like block states >1.13.
  We can resolve this by ditching .schematic and switching over to the newer .schem format. This newer format is from worldedit itself and supports the latest versions.

Edit: Switching formats doesn't seem like a good option too.

Another way to fix this is by making the schematic file bigger and having more space between the note blocks. This is kind of a dirty fix and I don't think this is the best way to go.

You can try to sign.

[Andrew-J-Larson]

Instead of using solid blocks then why not use something like a sign to hold the sand in place? It would work and allow the blocks underneath to play. you would just have to make sure the block state of the sign is set to be on the side of the stone or whatever block is being used for the frame of the note blocks.

[Andrew-J-Larson]

Or another idea is having slime blocks being used to keep the falling blocks in place? (of course though I know this would limit older versions of the game)

[HielkeMinecraft]

Signs don't work. I placed a sign above a note block, and it still wasn't able to play.

And slime blocks don't work either, because falling blocks will fall even if they are attached to slime.

[Andrew-J-Larson]

Well... Looks like you're going to have to fix it the long way sometime then...

The bad part about switching formats is that the schematics won't work with MCEdit anymore...
But that's what you get when you don't update your program in years.

What's the problem with WorldEdit?

[HielkeMinecraft]

It only uses the .schematic format.

I've discovered that switching to .schem isn't an option anyway, because WorldEdit for older versions of Minecraft only support .schematic. Ugh.
This is getting real difficult.
