Could you please add a

previous costume
previous backdrop

Blocks?
To make a previous costume/backdrop, you would need to do

switch costume to [((costume #) - (1)) v]
switch backdrop to [((costume #) - (1)) v]

Or if you want to make a loop(go 321987654), you would need to make a VERY complicated program.
It would very good for programs where you rewind something, or when you need to animate a sprite(a lot of costumes) to a special state and then animate it back to normal.

I think this block will be fery useful for new scratchers.

Also, this is my first forum.

You've shown the workaround in your suggestion, and considering how simple it is, I don't think a previous block is needed.

You meant this:

switch costume to ((costume #)-(1))
switch backdrop to ((backdrop #)-(1))

I don't exactly understand what you mean, but I think that if I understood, I would disagree.

Just use the workaround.

I agree.
It would be fery, fery, fery useful for new Scratchers, because it would be better if they figured it out themselves, or asked about it in the forums. That way, they would learn something new instead of just using the pre-made block and continuing to live without the knowledge of the forums or operator blocks.

I don't support because of the reason @CatsUnited described above. I know that some of you are ready to say "Then why does the

change x by ()

block exist?“ Well, because it is a basic feature in Scratch programs, and the ”previous costume" isn't that basic.
Oh, and notice the difference between “change by ()” and “next”. The former one is “change by any value”, while the latter is always “change by 1”.

I meant like from costume 2 to cost. 1 to cost. 9 (last costume. this number could change in your programs) and then to 8 and so on.

Just use the workaround.

What workaround?

P.S. also, fery is actually spelled very
P.P.S. The blocks glitched out when I did the workaround

no support. just do:

switch costume to [previous costume v]
switch backdrop to [previous backdrop v]

So like

switch costume to [2 v]
forever
switch costume to ((costume #) - (1))
end

? I'd say that's a pretty simple workaround.

A previous backdrop block technically already exists - it's one of the drop-down options for the existing switch backdrop block:

switch backdrop to [previous backdrop v]

alongside next backdrop and random backdrop.

And as for previous costume, it appears that this block has been suggested before in this topic.
In which case, please resume the discussion there so we can keep suggestions organized and in one place. Thanks!

Okay then… I'll* report this, so that the Scratch Team can close this.
*Four vertical lines, the second one 3 times shorter than the others… I don't like this font as much as before.
