Core Principles and Functionality:

The HUD is mostly out of the way with only necessary information on the screen at all times.

HUD Elements

• Health & Status Indicators: 

  • Health is displayed in the form of a filled bar based on the player's health percentage. 

  • In the middle of the bar, the exact number of health is displayed. 

  • Any status effects the player receives will be shown below the health bar in the form of an icon and a time limit displayed over the status.

• Ammunition: 

  • Ammunition is displayed in the bottom right of the screen next to the icon of the equipped weapon in the form of a fraction of ammo/max ammo.

• Objective Markers: 

  • The key door to get out of each level will have a marker over it at all times, and any sub-objective will have a marker at its general location.

• Interaction Prompts: 

  • A button prompt with the E key will show up near any object that can be interacted with within 1 meter of the object.

Dynamic Elements

• The health bar and weapon UI will not be shown on the player's screen when the player is not in a combat area/has not taken damage within 1 minute.

• A slight but noticeable red flashing only appears when the player has 10% or less health remaining. It also makes a slight beeping noise.

• The Inventory Log only appears when an item is picked up.

Tutorial Message Area:

• On the right side of the screen, there is a section for pop-ups that occur when the player encounters a new object or enemy a short description of the subject and controls if applicable.
