I want to make a dynamically moving damage counter for my dungeon crawling game with clones, but I have no idea how and can't find a tutorial.
help would be VERY appreciated.

do you mean like a health bar that follows the player

no, I mean numbers that fly out when the player deals/takes damage, heals, etc.

if you've played castle crashers, you'll know what I mean

You could do this with a sprite that contains costumes for numbers 0-9. Hide this sprite and when you want a number to appear you could use a broadcast or maybe better still create a clone of that sprite. and have something like this

when I start as a clone
go to [player v]
switch costume to (health)
set size to (10) %
repeat (10)
change size by (10)
end
delete this clone

You could add ghost effect etc.

Hello, sorry to be the bare of bad news but there is no way to make a counter move

but there are many tutorials on how to replicate a moving counter using the scratch Pen Extension

*if you found this helpful please let me know

but to make a health damage that fly's out the player all you need is a costume list

make costume's numbering from 10 - 100

and if the tool that the player is using dose 20 damage, the 20 damage costume will offset above the players head
