I am looking for how to use some code for my health bar. It is a green yellow red bar with three health settings and when it reaches zero it disappears. The problem is I don't know how to code it and I don't want to use variables. Here is the current code:

when green flag clicked
go to x: (50) y: (0)
when I receive [message]
switch costume to ((backdrop #) - (1))

Also, it doesn't change the costume number.

when green flag clicked
say [Hi!] for (2) secs
say [Good Morning/ Afternoon/ Evening!] for (2) secs

So to recap, you're looking for:
three health settings
disappears when it reaches zero.
you don't want to use variables.
it doesn't change the costume number

So, your first two points are relatively easy to pull off on their own, but this would be a bit more difficult without variables. There are other solutions, however, your last note makes this even harder.
If you're not looking to use complicated code, you probably should just make a new sprite, so it can change costume number, but if that's not an option, you may want to consider putting the health bar costumes in the backdrop or using cloning in the sprite. Cloning is a great solution and the abstraction definitely can help compact your work, but it kind of only works best with variables.

If you figure out which one of these you'd like to use (or if you don't like any of these options, which is fine too) just let me know and I'll happily try to help you figure it out from there!

It's fine if the costume number changes. I was saying that it is not changing the costume number

when green flag clicked
say [Hi!] for (2) secs
say [Good Morning/ Afternoon/ Evening!] for (2) secs

Oh, that's an easy fix! You have to take out the block that looks like this:

(backdrop #)

and replace it with this:

(costume #)

(you can find this replacement block in the “looks” section of your sprite.)
The reason your previous one didn't work was because the code you wrote was made to change the costume of the backdrop, not the costumes of sprite itself. It's an easy mistake to make, since the two blocks look so similar- I've made the same mistake myself many times haha-
Anyways, I hope this helps, and sorry for misinterpreting earlier!

I gotch you fam

when I receive [update_healthbar v]
clear // it's "Erase all" in Scratch 3.0 blocks
set pen size to ((size) / (25))
pen up
change y by (((b) * (0.65)) * ((size) / (100)))
change x by (((a) * (-0.5)) * ((size) / (100)))
set pen color to [#ff0000]
pen down
change x by ((a) * ((size) / (100)))
pen up
change x by ((-a) * ((size) / (100)))
set pen color to [#3fff00]
if <((volume) / (100)) < [0.67]> then
set pen color to [#ffff00]
end
if <((volume) / (100)) < [0.34]> then
set pen color to [#ff0000]
end
pen down
change x by (((a) * ((volume) / (100))) * ((size) / (100)))
pen up
change y by (((b) * (-0.65)) * ((size) / (100)))
change x by (((a) * ((0.5) - ((volume) / (100)))) * ((size) / (100)))
if <not<(volume) > (0) >> then
clear // it's "Erase all" in Scratch 3.0 blocks
end

WHAT THIS DOES:
it creates a healthbar over the sprite with the size of the healthbar fluctuating with the costume and size of the sprite, using volume as the health. It will erase itself after health drops below zero
NOTE:
-“a” is NOT a variable, as you specifically requested no variables. It is the WIDTH of the costume. Since you do not want to use variables, you have to input this manually. You find the WIDTH of your costume by going to costumes, finding where it displays a mini-version of your costume, looking under the costume name at the WIDTH x LENGTH numbers, then inputting the right one.
-“b” is NOT a variable, as you specifically requested no variables. It is the LENGTH of the costume. Since you do not want to use variables, you have to input this manually. You find the LENGTH of your costume by going to costumes, finding where it displays a mini-version of your costume, looking under the costume name at the WIDTH x LENGTH numbers, then inputting the right one.
-this will not work with clones since the VOLUME is the same for BOTH clones and the original sprite.
Hope this helps
