I have a setup similar to this:

when gf clicked
set [var v] to [0.1]
go to x: (0) y: (3)
point in direction (90 v)
clear
set pen color to (0)
pen down
forever
  move (dir) steps
  turn cw (1) degrees
  if <(direction) = [90]>
    pen up
    change y by (6)
    pen down
    change pen color by (10)
    if <(var) = [2.1]>
      play sound[Pop v]
      stop script
    else
      change [var v] by (0.1)
    end
  end
end

but for some reason, the if block doesn't fire the code inside of it. Any ideas?
EDIT: Just a note, the say block is replaced by code to stop the script and play a sound, but the Scratchblocks BBcode didn't work on it for me for a weird reason.

Actually, the way you have the script, var is equal to 0.2. smile

Because your changing var by 0.1 forever. When it's changing forever, it goes on and on and on. Try this:

when gf clicked
set [var v] to [0.2]
forever
 if (var) = [2.1]
 say [var is more than 2.1!]
 end
end

*facepalm* I should put my script PROPERLY.

It repeats the loop until var is equal to 2.1, but for some reason the []=[] block seems to only work sith STRINGS.
EDIT: It doesn't even work when comparing to a variable that's set EXACTLY THE SAME!

Hmm. Does anyone know at all? Scratch seems to think 2.1 isn't 2.1

Show the variable and see if it ever reaches 2.1

Wes64 · 2012-12-19 16:00:44

if nothing else works, just do (var)>2 instead

I've already tried that. I've also tried the single stepping mode, and Scratch just skips the if block it's in.

Yes, it worked. Mabye it's because Scratch is changing the value BEFORE checking, even though I set it to not do that.

Firedrake969 · 2012-12-20 11:42:42

It only fires off if the direction = 90. Maybe it's because of that?

No, it's not. Go to my latest project and download it, That's the problem I had it with.

The problem might base on loss of precision related to floating point arithmetic.
Try to use integer variables for loop control.

Var is set to 2.1 but the <[] = []> block returns false when checking?
