Hello. How can i make an assignment on changes of a variable so that will run logic if it’s changed?

Quick solutions that come to my mind, either:

  1. Create a setter method that will set the variable’s value and fire the logic you want afterwards. For consistency, you’ll have to use this method everywhere you want to change a value. Creating Setters/Getters is a common practice in programming overall, and if you are using C++, there is even a property specifier that you can use instead: UPROPERTY(BlueprintSetter="abc") - All UPROPERTY Specifiers · ben🌱ui
  2. Make the variable replicated and use OnRep_ functionality. This will make this variable weight a little bit more, and you’ll have to make the owning actor replicated, but this works exacly how you wanted in the first place.
