Allow More Chat Component in NBT Tags (e.g. CustomName)

I recently realized that NBT tags like CustomName and Lore only supports "text" as its base. If you do "selector", it'll use the target selector (e.g. @p[tag=bananas]) as the text itself. If you use something like "score", it gives nothing.

 

It might cause lag if the components update every tick, but take a look at signs. It supports all chat components mentioned above. Even if the sign only updates its dynamic values on creation or when /data modify runs that specific line again, it's sufficient for items and entities as well. Of course, it shouldn't be able to run events like "clickEvent".

 

 

Here's an example:

/summon zombie ~ ~ ~ {CustomName:'[{"score":{"objective":"health","name":"@s"}}," / ",{"nbt":"Attributes.[{Name:"generic.maxHealth"}]","entity":"@s"}]'} In recent system, it will summon a zombie with no name. My described behavior is to let the zombie have the name "20 / 20" shown (in this command, it will only be " / 20" (P.S. It's just an example, as a command block expe*cough*, I can fix that. But I have to show variations) ).

Then, to update the name, we can do, /execute as @e[type=zombie] run data modify entity @s CustomName set value '[{"score":{"objective":"health","name":"@s"}}," / ",{"nbt":"Attributes.[{Name:"generic.maxHealth"}]","entity":"@s"}]'. This can allow the zombie's name change every time /data modify is called.

 

This is a suggestion, and I'd / we'd like to see it implemented.

    (I wrote this here cuz the post would exceed 1500 words)

    This suggestion has some potentials for map making. For instance,

    1. string concatenation in general

    2. showing scoreboard score on tooltip (pairing up with https://feedback.minecraft.net/hc/en-us/community/posts/360011485651-String-type-for-execute-store-command)

    3. health bar for non-custom mobs

    4. custom durability bar

    5. a whole keyboard input system

    No comment on the suggestion itself, but in case you are unaware, you can modify a sign to the desired text component (using selector/score/whatever), and then use /data modify to copy it to the desired mob. So at least there is a workaround for now

    You can actually do it (even if it's not the simplest way to do it) by copying those data into a sign, then those data are translated into fix JSON Compound, and you can copy them into entity's CustomName.
