UMG
UMG, or Unreal Motion Graphics UI Designer, is Unreal Engine 4's main tool for creating UI for things such as menus, in-game HUD elements such as health bars, and other user interfaces you may want to present to the player.
In the SuperSideScroller game, we will only be using the Text widget to construct our Coin Collection UI in Exercise 15.04, Creating the Coin Counter UIÂ HUD Element. We'll learn more about the Text widget in the next section.
