Scratch

I want sprite one to control the action of sprite 2. First the script for sprite 1, then for sprite 2.

when gf clicked
set size to (100) %
go to x: (-160) y: (90)
set [sound_exist] to [0]
repeat (20)
   move (7) steps
   next costume
   move (7) steps
end
if <touching [sprite 3] ?>
   go to x: (160) y -90)
   set size to (50) %
end
broadcast [sound_exist]
play sound [Pink-Get This] until done
change [sound_exist] by (1)
broadcast [sound_exist]
glide (10) secs to x: (-160) y: (90)
stop script
[/scratchblocks]

when I receive [sound_exist]
show variable [sound_exist]
switch to costume [jodi1]
go to x: (-130) y: (-13)
set size to (100) %
repeat until <[sound_exist] = [1]
   switch to costume [jodi2]
   wait (0.25) secs
   switch to costume [jodi1]
   wait (0.25) secs
end
go to x: (-167) y: (-63)
set size to (50) %
stop script

the problem is the repeat loop never ends. I am under the impression that when the variable evaluates true that the loop is broken. Where am i going wrong? Thank you for your help.

and again!

when gf clicked
set size to (100) %
go to x: (-160) y: (90)
set [sound_exist] to [0]
repeat (20)
   move (7) steps
   next costume
   move (7) steps
end
if <touching [sprite 3] ?>
   go to x: (160) y: (-90)
   set size to (50) %
end
broadcast [sound_exist]
play sound [Pink-Get This] until done
change [sound_exist] by (1)
broadcast [sound_exist]
glide (10) secs to x: (-160) y: (90)
stop script

when I receive [sound_exist v]
show variable [sound_exist v]
switch to costume [jodi1 v]
go to x: (-130) y: (-13)
set size to (100) %
repeat until <(sound_exist) = [1]>// Is this right
   switch to costume [jodi2 v]
   wait (0.25) secs
   switch to costume [jodi1 v]
   wait (0.25) secs
end
go to x: (-167) y: (-63)
set size to (50) %
stop script

Ahh Fixed

Music is 3 minutes 14 seconds

Let me try and duplicate the operator block I am getting:

<[sound_exist] = [0]>

let's see if I understand how this works.

Nope, still no pointy ends! I'm gonna go get a pizza!

Closer, but I still don't get the pointy ends...Maybe I need a space between the greater than symbol and the bracket.

< [sound_exist] = [0] >

let's see what happens now

Try using normal brackets like this,

<(sound_exist)=[0]>

Which makes

<(sound_exist)=[0]>

instead of square brackets like this

< [sound_exist] = [0] >

Which makes

< [sound_exist] = [0] >

I hope I helped, letmethink

When you write the code out in the forum the operator looks correct when you post, but when I fill in the square white boxes of the = operator in the Scratch program the block has pointy ends and a square white rectangle with the string in it.
Also, I don't know if the second broadcast block is needed. I assumed when the value changed that I had to re-broadcast to effect the change since the script stops after the next block. Once the broadcast block is triggered by the script does it broadcast continuously and reflect changes in value when they occur or does it broadcast just once with the value the variable is at when triggered?
And, I'd be glad to send you the project file. What's the best way to do so? E-mail it to you as an attachment? Or is there some way to post it here besides writing out the scripts for all three sprites? I am going to write out the script for one of the sprites with the offending operator in it to see what it looks like when I post it. If it looks as it should when posted I may have a bug in my Scratch program. If so, it would reflect the story of my life! Thank for your help!

This is what it should look like in my scratch program's scripts panel, but doesn't! The green operator has pointy ends and sound_exist is in a white rectangle. Is there any way of checking the bbcode in my Scratch program?

yes I did. do you drop the variable block into the operator block? or type the variable name into the operator block, which is what I did.

I happy I could help, I thought your typed variable looked suspicious.
