Minecraft setblock chest cannot use replace

minecraft-commandsminecraft-java-edition

I am aware that ordinarily in Minecraft one can use:

\setblock x y z minecraft:block0 0 replace minecraft:blockname1

to set a block with the ID name: block0 on the coordinate, but only if the block which was before has ID name: block1; this does however not seem to be the case if the block I desire to set is chest (or other blocks which can contain things, such as for instance hoppers). If I type

\setblock x y z minecraft:chest

it works fine

\setblock x y z minecraft:chest 0 replace

works as well; however

\setblock x y z minecraft:chest 0 replace minecraft:block1

(of course I don't write block1, I instead use any real blockname)

fails with the error message:

Data tag parsing failed: Invalid tag encountered, expected '{' as first char.

I have (obviously) attempted this:

\setblock x y z minecraft:chest 0 {} replace minecraft:block1

Which does cause chest to be placed, but it does however not only do if the block that was there before had ID name: block1.

My question: Is there a way to use the setblock command to set a chest (or other item containing blocks) but only if it replaces a specific other block?

/setblock does not support replacing specific blocks. The /fill command does:

/fill x1 y1 z1 x2 y2 z2 block1 0 replace block2 0

However, if "block1" is a tile entity, then you cannot replace a specific block and must instead supply NBT data. See this explanation by Searge:

Replacing blocks with tile entities is not supported, this is due to a limitation in the parsing of commands. It may be changed in the future, but not until after 1.8.

A chest is a tile entity, meaning you cannot use this to replace a specific block with a chest.

As a work-around, you could detect the existence of the particular block first using /testforblock:

/testforblock x y z minecraft:stone 0

And then use /setblock if that command succeeded:

/setblock x y z minecraft:chest

Minecraft – Using a command to replace wool blocks with command blocks which contain a command

This is pretty easy to do with 4 fill commands in command blocks: 2 for a fill clock (either a 20Hz clock or a single shot pair), and 2 to actually replace the wool. Add one more command block for a single tick button, and 2 more command blocks if your fill area contains air that you don't want command blocks in. I'll assume the latter, since it won't make a difference if there isn't any air blocks to fill initially. So, seven command blocks. This is what it looks like:

I'm using tilda notation in my command blocks to reference the 4x4x4 area with the wool, but it may be desirable to use absolute coordinates for production purposes. In any case, the commands in the command blocks are as follows:

fill ~2 ~1 ~ ~7 ~1 ~ minecraft:redstone_block (set the stone to redstone blocks)
setblock ~-3 ~ ~ stone_button 2 replace (quick reset the button, located on the right side of command block 1)
fill ~ ~ ~2 ~3 ~3 ~5 barrier 0 replace air 0 (replace the air with barriers, but there may be a better block to use, especially if players will be in the area)
fill ~-1 ~ ~2 ~2 ~3 ~5 air 0 replace wool 5 (replace green wool with air)
fill ~-2 ~ ~2 ~1 ~3 ~5 command_block 0 keep {Command:"setblock ~ ~ ~ wool 5 replace"} (replace the air with command blocks)
fill ~-3 ~ ~2 ~ ~3 ~5 air 0 replace barrier 0 (replace the barriers with air)
fill ~-5 ~1 ~ ~ ~1 ~ stone (reset the redstone blocks back to stone)

After hitting the button on block 1, we see the following:

As I said earlier, if your target area doesn't contain air blocks, then you can forego the two command blocks that set and reset the barriers. Simply remove them in that case.

Minecraft – Setblock for conditional command block

There is no tag for it. It's instead saved as the Damage value. See here for a list of values.

For your command, you'd add 8 to the Damage value, resulting in 11:

/setblock ~ ~-1 ~-3 minecraft:chain_command_block 11 replace {Command:"/testfor @p[score_Money_min=110]"}
