[stable goblet]

no i cant find any on google :/ idk what its accualy called

hold on

[whole mulch]

Closest is chat with /tellraw which is top left, or scoreboard display list

[dim grotto]

The only way is with a texture pack or as they said, the closest thing would be scoreboard sidebar display

[stable goblet]

damn it

[stable goblet]

how would i make it so if someones score is less than 0 or more than 3 it defaults back to said numbers?

kind of like this i mean

[whole mulch]

you can check if its less than greater than or in a range of numbers using
scores={objective=..0,objective2=0..,objective3=0..3}

[stable goblet]

what

[whole mulch]

i gave you the 3 possibilites in orders like i said:
less than objective=..0
greater than objective2=0..
range objective3=0..3

[whole mulch]

and for this you could use a range but inverse it, so @a[scores={objective=!-1..4}]
