How to Create Time and Score Summary Board when the game ends

Hello

I’m creating a fighting game. Use the blueprint system.And I have a condition of the game.

When the game starts

  1. The game will count down the time. And display time while playing the game.

When the game is over

  1. The game will display the number of rivals that win.

  2. The game will display the remaining time.

  3. The game will display the calculate and display percentage of the fight…

How do I use the method?

** What keywords will I use to do the above?**

I appreciate the advice.
