Make a bossbar which is assigned to multiple mobs.

[twilit plover]

You see the Raid bossbar during minecraft Raid? Its assigned to every raider mob. I can only create a bossbar for single mob in minecraft but I want to create single bossbar for multiple mobs.

[jade belfry]

Do you want to set the number of mobs in the boss bar?

[twilit plover]

yes

but i am not really sure what that means

[wooden geode]

take the health of all the mobs as scores, add them together, store it on the bossbar with execute store result bossbar

[jade belfry]

execute store result bossbar <id> value if entity <selector>

[twilit plover]

OK, what i cannot do is, "add"

how to add healths

like

[wooden geode]

you can use scoreboard players operation ENTITY1 SCOREBOARD += ENTITY2 SCOREBOARD to add two scoreboard objectives together and output the result in ENTITY1’s scoreboard value

[twilit plover]

ok += operator

[jade belfry]

why their health?

[twilit plover]

i will try to make one now

[wooden geode]

I mean you can also do the amount of entities if you want but then it will only go up/down when one is killed

This goes up or down when one is damaged

[jade belfry]

Well, if you want to count your health, do it. mobs are counted in vanilla

[twilit plover]

i want it to empty a little, when one is damaged or killed, and want it to fill back up if you heal the mobs assigned to bossbar

[wooden geode]

yeah then you’re want to count their health

[twilit plover]

i will try what silabear said

+= operator

[jade belfry]

is the number of your mobs the same and the amount of maximum health will always be the same for different waves of mobs?

[twilit plover]

wait, what if the entities are dynamic in count? Do i make more scoreboards?

[wooden geode]

You could loop through them

[twilit plover]

its not fixed how many entities are assigned to bossbar

[wooden geode]

so for each entity, set it’s current health to some value on a scoreboard, and add it to the original value

do that for each entity and you’ll have the health of all the entities combined :P

[twilit plover]

no, max health is unfixed, nothing is fixed, i just want mobs with {Tags:["bossbar"]} to be assigned. Doesnt matter how many or how much health

[jade belfry]

then will you indicate the maximum amount of health in the bossbar at the beginning of each wave?

[wooden geode]

you’ll also need to set the max value of the bossbar to the max health of the mobs combined, you can do that by adding all their health when they are all at full health (start of battle maybe) and then store that to the max value of the bossbar (again with execute store result bossbar)

[twilit plover]

no, the bossbar will just be filled up completely when the wave of mobs spawn, and when you start killing/damaging one by one, the bossbar will go down

[twilit plover]

store* i think

[wooden geode]

yeah mb

[twilit plover]

hold on, how to know max health of a mob if its health is not full

[wooden geode]

could you maybe get their base max_health attribute?

[twilit plover]

oh yes attribute command

right

[jade belfry]

start_wave function

summon zombie 96 13 19 {Tags: ["bossbar"]}
summon spider 54 15 86 {Tags: ["bossbar"]}

...

scoreboard players set *amount_health main_score 0
execute as @e[tag=bossbar] run function namespace:add_amount_health
execute store result bossbar <bossbar_id> max run scoreboard players get *amount_health main_score

tick function

scoreboard players set *amount_health main_score 0
execute as @e[tag=bossbar] run function namespace:add_amount_health
execute store result bossbar <bossbar_id> value run scoreboard players get *amount_health main_score

add_amount_health function

execute store result score *temp main_score run data get entity @s Health
scoreboard players operation *amount_health main_score += *temp main_score

[twilit plover]

/attribute @s generic.max_health base get

[wooden geode]

useful, but try not to spoonfeed

[jade belfry]

I helped with the code

[twilit plover]

damn, genius

[twilit plover]

thats really useful tbh

[wooden geode]

i agree

but spoonfeeding isn’t good

[jade belfry]

note that you can use the names of fake players and store them on the same objective
*temp main_score

[twilit plover]

its not spoonfeeding, its the right way of doing it

[jade belfry]

you can replace main_score with your scoreboard for fake players

[wooden geode]

im not gonna argue but it is, #💬┃general if you want to discuss it

[twilit plover]

yeah, use illegal characters like * . ( etc in fake player names

[twilit plover]

later

leme try doing that first

[jade belfry]

if you use # at the beginning of the fake player's name, then it will not be displayed in the sidebar, so it is usually used #

[wooden geode]

I suggest using a .

Viewing it in the sidebar is very useful

[twilit plover]

thats really useful information, thank you so much ❤️

[twilit plover]

i do use a .

namespace.scorename (while also trying to adjust it till 16 or less characters)

[jade belfry]

it seems to me that in this case it is necessary to show what the code looks like, then the person will try to make loops with fake players himself

[wooden geode]

as I said this isn’t the place to discuss it

[jade belfry]

it is not useful for optimization 😄
tellraw @a [{"score":{"name":"#temp","objective":"main_score"}}] is very useful

[wooden geode]

for debugging lol

[jade belfry]

yes

for debugging

[wooden geode]

Why would I care about optimising it if I’m debugging?

[jade belfry]

ah, if you immediately change the name after debagging to #, then good. it's just that when I write the code, it's very large and I initially use # so that I don't get confused with the replacement later

[wooden geode]

I keep it as . so people who download/fork can also debug

[jade belfry]

I suggest we stop there

[wooden geode]

finally

[twilit plover]

I would close this thread with a simple project bcoz the information you both provided really means alot to me and I would like to prove it.

but if it's disallowed, I can close it rn

[twilit plover]

Ok, done with the project
