UI and UX design


The _user interface_ (UI) combines artistic visual design with communication-centric information design to produce menus, shop layouts, heads-up displays (HUDs) and other interfaces that players interact with. The _user experience_ (UX) relates to how players interact with the game, how they make their choices known, and how they move from one choice to the next. While UI and UX often work collaboratively, UX carries a more significant focus on interactivity and the player's experience rather than the visual and informational design of the UI.

Note

Optimize your interface by using Experiments to test how different button placements or HUD layouts impact player engagement. You can also use Configs to toggle platform-specific UI elements or seasonal themes instantly across all active servers to keep your game feeling fresh.

UI

The UI shares vital information like hit points, quest objectives, and prices that allow players to make decisions and navigate the game. Because it is often the primary way in which games communicate with the player, UI is critical to players' experience. Poorly designed UI can leave players confused and frustrated and lead to poor retention, while expertly designed UI can contribute to engagement and monetization. Effective designed UI employs the following principles:

Prioritization

Sharing the most significant information first is known as the Hierarchy of Information. This is particularly crucial in games where players frequently make instantaneous decisions based on a restricted set of information. When prioritizing the UI, identify what is essential or most relevant to the player's experience and ensure it's both accessible and easy to locate. Consider these questions:

Important information and features change depending on factors like the role the player assumes, their location in the 3D world, and the items they hold. The UI can be designed to present only what matters contextually – swapping out the buttons and information depending on what's useful in each context. This ensures that players always have what they need, without the clutter of everything that they don't.

Examples

Irrelevant elements can cause confusion and distraction. Spellbound RPG has a clean, minimalist UI that is particularly crucial for mobile interfaces, as small screens can easily get overwhelmed with excessive buttons, screens, and text.

In Super Striker League, player interactions vary based on whether they control the ball. Without the ball, players can Sprint and Tackle to regain control. Once in possession, the buttons switch to Deke and Pass, enabling players to dodge opponents and pass the ball. By alternating these buttons, the UI stays contextually useful, avoiding unnecessary distractions.

In The Survival Game, players need to be aware of their health and hunger status, and have quick access to their map, inventory, and tools. This information allows them to make decisions and prioritize actions for survival. If this information or tools are hard to find or missing, survival becomes more challenging and needlessly frustrating.

Attention

Despite a minimalist, prioritized, and contextualized UI, players might still need assistance locating what they need. UI designers can use several visual tools to capture and guide players' attention, such as:

Moderation is key with these tools. Excessive use of bright, moving elements might overwhelm and confuse players rather than aid them.

Examples

In Jailbreak's season pass UI, a stripe of golden yellow lies beneath the season pass-exclusive icons, drawing attention to the premium rewards and making them visually distinct from the free ones.

In Dragon Adventures, visual priority is given to the highest-value coin bundle by increasing its size and separating it with more padding, to distinguish it from smaller bundles.

Visual language

In addition to directing players' attention to the most important elements on the screen, UI designers develop a visual language to help players understand what they're seeing. A visual language is a set of deliberate and consistent design choices that provide information at a glance about an element's purpose, status, associations and relevance. The language is built from tools like shape, color, and style. Some of the uses for visual language include:

Icons

Icons can employ a visual identity that conveys meaning and associations. For instance, icons related to specific stats may share a color palette and similar shapes, enabling players to recognize and understand their function.

Buttons

As a prevalent form of player input, buttons must be easy to identify. Housing buttons in a container, such as a color surrounding the text or icon, distinguishes them from the background, making them appear interactive. Adding highlights or shadows can enhance their tactile appeal by suggesting 3D depth.

Text

Headers and titles containing significant high-level information should be larger and bolder than body text. Colors that are highly legible and contrast well against the background color they'll be displayed over should be considered. Stylistic choices like color and bolding can highlight important information like in-game items, stats, or abilities. Always prioritize legibility when choosing a font.

Once the visual language has been designed, it can be documented in a Style Guide, a set of rules and examples that help everyone on the team understand how to apply the language consistently across the game.

Conventions

Conventions are commonly-applied design choices that are seen across many different games. Some examples include:

Given their widespread use, players are typically familiar with such conventions. Leveraging this familiarity can make an interface more intuitive and lessen the need for game-specific instructions. Playing games within your target genre can help identify conventions players may recognize. A UI designer may opt for a unique approach to better fit their game, but knowing these conventions informs their decision-making process.

Consistency

Whatever decisions a UI designer makes, they should consistently apply them throughout the game. Consistency helps players learn to navigate the game more efficiently and prevents confusion and frustration.

Here are some examples of UI consistency in a game:

These choices are deliberate, aiming to facilitate player comprehension and navigation. By applying them consistently, they enable players to associate related elements, identify important items, develop muscle memory, make swift informed decisions, and spend more time immersed in the game.

UX

UX design relates to how players interact with the game, how they make their choices known, and how they move from one choice to the next. Although UX often works hand-in-hand with user interface (UI), it is more focused on interactivity and player experience than the visual and informational design of UI.

Understanding players

A primary goal of the UX designer is to create interactions and flows that are intuitive, unobtrusive and convenient for players to use. That process starts with an understanding of the players themselves, the intended audience for a game. When identifying players of a game, consider the following:

After considering these factors and selecting a target player group (or groups), get to know them by meeting them, playing with them, and learning about their goals and preferences to better inform design choices.

Design interactions

Interactions are features that allow players to experience and communicate their choices in a game. UX designers want those interactions to be intuitive, and require as little explanation as possible. To do this they utilize:

Conventions

Conventions are UX designs and principles that players may already be familiar with from other games.

"E" proximity prompt in Mermaid Life

Examples of conventions include:

Conventions become established when a particular implementation or design choice grows in popularity due to its ease of use. "C" to crouch, for example, is easy to remember due to it being the first letter in the word crouch, and is conveniently located next to WASD, the keys that players use to navigate. It is an easy interaction to perform quickly and under pressure, which is ideal since attempting to hide or flee from an approaching threat is a common use case for crouching.

Metaphors

Metaphors relate an abstract concept to a more familiar one, creating a shortcut to comprehension. In this example from Spellbound Wizard RPG, the act of casting magic spells is performed by drawing cards from a deck. The deck-based UI/UX grounds the abstract act of casting spells, which has no real-life expression, into something that players can relate to more easily and quickly understand.

Feedback

Communication from the game to the player is known as feedback. Feedback helps players understand that an action that they have taken. It can contribute to learning how the game functions and add an extra layer of polish that makes a feature more satisfying to use. Some examples of feedback include:

When feedback is missing or insufficient, players might not know what they've accomplished, understand whether the effects were good or bad, or even know whether the feature they're using is functioning correctly or experiencing bugs.

Design flows

Multiple interactions are often required for a player to complete a goal. UX designers are concerned with how players navigate from one action or UI screen or choice to the next and make sure that these paths are logical and convenient.

For example, to equip an item on an avatar in Berry Avenue RP, a player must:

Avatar customization flow in Berry Avenue RP

These steps taken together represent the avatar customization flow. This flow is simple and straightforward, with as few steps as possible needed to equip an item. Because players do not have to perform many actions or think too much about what they need to do, this flow is low in friction, a measurement of the effort required to reach a goal.

Designing efficient, low-friction flows requires careful consideration of use cases. Those use cases can be expressed as player goals such as:

These goals then guide the UI and UX design of the feature:

Designers can then begin to lay out the UI and plan the steps that players will take to complete the goal of modifying their avatars. This process can be aided by the use of a flow chart, which visually depicts the players' actions as they navigate the UI. These diagrams can help to identify overlooked steps, pain points where the steps are unclear or inconvenient, and excessive friction.
