Scratch does not have the ability to define reporter blocks, but they can be simulated using variables.
Creating the Custom Block and Variable
define . . . // Change . . . to the description you want. Add required parameters if needed. . . . :: grey set [return v] to (. . . :: grey)
Example
// create a custom multiplication block define Multiply (n1)(n2) set [return v] to ((n1) * (n2)) stop [this script v] when flag clicked ask [What is the first number?] and wait set [num1 v] to (answer) ask [What is the second number?] and wait set [num2 v] to (answer) Multiply (num1)(num2) say (return)
You could also create a boolean:
define does (n1) equal (n2)? set [return v] to <(n1) = (n2)> stop [this script v]
Then you could insert it into an if statement
if <(return) = [true]> then Do something :: grey end
