set [old value v] to (value)
forever
if <(variable) = ((old value) - (1))>
change [variable 2 v] by (-1)
end
set [old value v] to (value)
end

That wouldn't work the same way.

Please explain how your block would work.

I believe this block can be created using this script:

set [oldval v] to (whatever)
wait until <[0] = [0]>
if <not <(oldval) = (whatever)>>
 whatever you want to happen
end

That would detect any change at all.

This script would detect a specific change:

set [oldval v] to (whatever)
wait until <[0] = [0]>
if <(oldval) = ((whatever) + (input))>
 whatever you want to happen
end
