Type Boolean

The () = () block is an Operators block and a Boolean block. The block checks if the first value is equal to the other value. If the values are equal, the block returns true; if not, false. This block is not case-sensitive.

In Scratch 1.3 and before, it only accepted numbers as values.

Example Uses

If an action must be performed if a variable equals certain amount, this block can be used.

Some common uses for the () = () block:

  • Pausing a script until a variable reaches a certain amount
when flag clicked
wait until <(score) = [10]>
say [Good job!]
when green flag clicked
ask [Was my joke funny?] and wait
if <(answer) = [yes]> then
  say [Thank you!] for (2) secs
end
  • Checking if boolean values are the same:
when gf clicked
if <<mouse down?> = <touching [sprite 1 v]?>> then //fast way
say [Either you are clicking and I am on sprite 1, or you are not clicking and I am not on sprite 1.]
end
if <<<mouse down?> and <touching [sprite 1 v]?>> or <not <<mouse down?> or <touching [sprite 1 v]>>>> then //Harder way
say [Either you are clicking and I am on sprite 1, or you are not clicking and I am not on sprite 1.]
end
  • Comparing different values
if <(x position) = (size)> then
say [The sprite size and x position are equal.] for (5) secs
else
say [The sprite size and x position are not equal.] for (5) secs
end
  • Doing something when there are 0 lives left
when green flag clicked
forever
if <(lives) = [0]> then
say [uh oh...]
end

Workaround

Main article: List of Block Workarounds

The block can be replicated with the following code:

<not <<(a) > (b)> or <(a) < (b)>>>

The following also works:

delete (all v) of [list v]
add (a) to [list v]
if <[list v] contains (b)> then
set [result v] to [true]
else
set [result v] to [false]
end
