Understanding Variable Scope in Figma Prototypes

In Figma prototypes, variables can be used to store values that change during interactions. Which statement best describes the scope of a variable defined in a prototype?

A Variables are local to the frame where they are defined and cannot be accessed outside it.

B Variables are global and accessible across all frames and components in the prototype.

C Variables are shared only between components nested inside the same parent frame.

D Variables exist only during a single interaction and reset after it completes.

💡 Hint

Think about how variables help maintain state across different screens in a prototype.

In Figma prototypes, variables are global by default, meaning they can be accessed and updated across all frames and components, allowing consistent state management throughout the prototype.

Using Variables to Control Prototype Flow

Consider a Figma prototype where a variable step controls which screen is shown. Initially, step = 1. After clicking a button, step increments by 1. What is the value of step after clicking the button twice?

Figma

Initial step = 1
On button click: step = step + 1

A 1

B 2

C 4

D 3

💡 Hint

Each click increases step by 1 starting from 1.

Starting at 1, the first click sets step to 2, the second click sets it to 3.

Fixing Variable Reset Issue in Prototype

A designer notices that a variable score resets to 0 every time the user navigates to a new frame, losing the accumulated value. What is the most likely cause?

A The variable <code>score</code> is defined as a local variable inside each frame instead of a global variable.

B The variable <code>score</code> is not initialized before use.

C The prototype does not have any interactions updating the <code>score</code> variable.

D The variable <code>score</code> is set to reset on every frame load by default.

💡 Hint

Consider how variable scope affects persistence across frames.

If score is defined locally in each frame, it resets when navigating to a new frame. Defining it globally preserves its value across frames.

Visualizing Variable Changes in a Prototype Dashboard

You want to create a dashboard in your Figma prototype that shows the current value of a variable progress as a percentage bar. Which visualization approach is best practice?

A Use multiple fixed rectangles stacked vertically to represent progress steps, without linking to the variable.

B Display the <code>progress</code> value as plain text only, without any graphical element.

C Use a rectangle shape with width dynamically linked to the <code>progress</code> variable value, ranging from 0% to 100%.

D Change the background color of the entire frame based on the <code>progress</code> variable.

💡 Hint

Think about how to visually represent a percentage value clearly and intuitively.

Linking the width of a rectangle to the progress variable creates a clear, intuitive progress bar that updates dynamically.

Designing a Multi-User Prototype with Shared Variables

You are designing a Figma prototype simulating a multi-user environment where users can update a shared variable status. Which limitation must you consider?

A Figma prototype variables are local to each user session and cannot be shared in real-time across multiple users.

B Variables in Figma prototypes automatically sync across all users in real-time without extra setup.

C Variables can be shared only if users are collaborating in the same frame simultaneously.

D Figma prototypes support server-side variables for multi-user synchronization.

💡 Hint

Consider how Figma prototypes handle variable state in multi-user scenarios.

Figma prototype variables exist only in the current user session and do not sync across users in real-time, limiting multi-user shared state simulation.
