What’s the difference?

If your project grows, this would make it easier to maintain.

I just need to assign the result of dividing two numbers to a variable.

Is your Widget Blueprint inheriting from your class? Does the Progress Bar have the same name ‘Bar’?

You can change the Parent Class in your Widget Blueprint > Graph > Class Settings > ( Details ) Parent Class.

I need the health bar to correspond to the value of the Health variable, which is constantly changing. How to do this in C++?

The easiest way would be for you:

  1. Create the UserWidget in C++.
  2. Store the variable created by the function.
  3. Create a public function in UHealthBar to set the progress value.
  4. Call this function from your other class.

I don’t have examples in C++, before I did, but now I find it easier to leave the visual part in Blueprint.

Creating User Widget:

You need to store the variable returning from this function ( C++ or Blueprint ) to change its values.
