User Interface Design
Every game has some form of user interface — even if it’s just the title screen.
The UI is what helps the player see, understand, and control what’s happening in the game.
User interfaces are usually linked to game mechanics — for example, when a player takes damage (a game mechanic), the health bar (a UI element) shows their remaining health.
What is a User Interface?
A user interface (UI) is everything the player sees and interacts with on the screen. It helps them:
-
Understand what’s going on
-
Make choices
-
Control the game
A good UI is clear, simple, and useful.
What can a UI show a player?
A UI can do lots of different jobs in a game. Here are some common uses:
-
Measure a player’s health – e.g. health bar, hearts, life icons
-
Show the score – e.g. number counter, scoreboard
-
Display the time – e.g. countdown timer or clock
-
Track progress – e.g. level completion bar or mission status
-
Give the player feedback – e.g. “Level Up!”, “Wrong Answer”, visual effects
-
Control the game – e.g. pause menu, buttons, inventory, dialogue choices
-
Help the player navigate – e.g. minimap, compass, objectives marker
Combining a variety of user interface elements can lead to a smoother, more engaging, and more enjoyable player experience. Too much UI can overwhelm the player, but too little and they won’t know what’s happening — the best games find the right balance.
