In Articulate Engage, the term "player" refers to the interface that appears around the perimeter of your interaction.
The player holds the navigation buttons and things like a title, seekbar, and volume controller.
It's easy to use Engage's Player Properties to make the player look the way you want. You can even customize the player with specific colors. To view the player settings, click the first tab on the Engage ribbon (its name corresponds to the type of interaction you're building) and then select Player.
The Player Properties window will appear where you can customize just about any part of the player, or even switch to a different player. The following tutorials will show you how:
Choosing Player Features
Changing the Player Colors and Font
Changing the Player's Text Labels
Changing the Browser Settings and Player Size
Changing the Player's Resume Behavior
Enabling Right-to-Left Language Support
Saving Your Player or Switching to a Different One
