What is the "!=" node in a Blueprint?

It’s “Not equal” comparison. Left and right pins are boolean ( true or false). It returns true when both variables from the left side are not equal, for example:

  • PIN1 - false
  • PIN2 - true

Output - true

But if both variables from the left side are the same (both true OR both false) then it returns false

In pseudocode you could write it as:

if( pin1 != pin2 ){
  // both variables are different
  // so let's do something
}
