I've come to a spot where I need Else or an Else If and there are no such blocks in Scratch. Has someone created an addition with those blocks in them?

There's If and If Else, but no Else or Else If ... is there a way for me to add Else blocks to Scratch easily or is it fairly complex and not worth the effort?

I think I can help you; I'll get back to you once I've finished. big_smile

You can alway's stack If-else blocks inside each other. But no, Scratch doesn't support this yet. It has been suggested Here before though.

JeanTheFox · 2010-07-29 15:29:00

It doesn't seem like it works too well. sad

For now I think you should just go with what you already have.

Extremely complex (but possible) and not worth the effort at all. Just put an 'if' into the bottom space in an 'if else.'

If you really want to make an else if block, reply back.

I'd also like to see some While blocks .... do those exist somewhere?
Does one of those things like BYOB or Panther or that other one have these sort of blocks?

Instead of While, Scratch has Repeat Until. Just put the condition you need inside a "Not" block. So

Code:

While (condition)
    Do whatever
EndWhile

In Scratch would be:

Code:

Repeat until NOT(condition)
    Do whatever
EndRepeat

Just one of those things with a simple workaround.

Uh, a while block is just the forever if block. No workarounds needed.

Nope, because
1) Forever if constantly checks for the given condition once it is executed.
2) Other scripts can't be placed under it.

While/repeat until checks for the given condition only as it reaches that point, and when the condition is no longer true, moves on to the scripts after it and stops checking. Forever if is actually equivalent to

Code:

Forever
    If (condition)
        code
    EndIf
EndForever

You always find a flaw in my theorizing.

Hey, I'm just sayin' tongue

Wait, is that a bad thing, or you mean I'm helpful at catching mistakes? I hope it's the second, I don't mean to be mean.

It was more meant to be a joke. (I should have added a tongue )

:p

I'm stuck already.
Pretty bad at Scratch, heh.
Klik & Play is easier.

Thanks for advice on the While thing ... it sorta confuses me though, wonder why they didn't just include a while ... <shrugs>

Oh, I have another question ... how can I make it so when pointing in a direction, the sprite does not flip upside down?
Do I have to make a left facing sprite and a right facing sprite and use extra code?
Or is there a better way?

Yes, there is a better way. On the top of the script panel, above the tabs for scripts, costumes and sounds, there is a picture of the sprite. On the left of it are 3 buttons. Click the second button down and you should be all set!

EDIT: 14 posts and I'm at 1000! big_smile

It depends. Do you want it to face only left/right, or just spin 360 degress around, but not be upside down? If the former, then use ScratchReallyROCKS's suggestion. If the latter, then yes, make another costume that is upside down (copy the original costume and use the vertical flip button in the sprite editor), and use something like this:

Code:

When Green Flag Clicked
Forever
If <Direction < 0>
    Switch to costume upside_down
else
    Switch to costume normal
EndIf

Sweet! .. I didn't notice those buttons were there.
Thank you ScratchReallyROCKS!

Kewl, that could come in handy later on.
Thank you Harakou!

You guys are great smile
