I created a regular interface only using two widgets: 1 is just a screen;
2 is just a strip of progress;
2 I connect 2 widget in the first. I will create a mashed controller for the character (and added it to the game controller).
And in the character controller I create logic so that you can calculate progress there. So the NOD 1 widget I can not connect with 2 - widget. Because I can’t make a public 2-widget (click on the eye in the variable) this function is not included. In version 4.27, I can open it there, and in the 5th version of the engine I never found information or inclusion functions
