You’re purpose is to show this straightforward UI right into a responsive one that appears good on all window resolutions.
Why Construct Responsive UI
Responsive UI is essential as a result of gamers might have totally different gadgets with totally different display screen resolutions.
Listed below are some frequent display screen resolutions on totally different platforms:
- Desktop: 1920×1080, 1366×768, 1280×1024, 1024×768
- Cellular: 667×375, 736×414, 800×360, 844×390

Responsive UI goals for a constant, pleasurable expertise on all screens.
Primary Data of Person Interface Design
Earlier than you construct a responsive UI, it’s essential to study a bit about UI Design.
Subsequent, you’ll find out about design decision, side ratio, and orientation.
Design Decision
When designing a consumer interface, think about inserting packing containers on a canvas.
These packing containers are the UI components, like labels and buttons. The canvas is your recreation display screen. Design decision refers back to the goal dimensions of the canvas, which helps decide the width and top of UI components to fulfill the design necessities.
Side Ratio
Side ratio is one other essential think about UI design. It’s calculated by dividing the width of the display screen by its top. By evaluating the side ratios of your design and the display screen, you’ll know if the display screen is wider, narrower, or the identical.
Right here’s a comparability of varied display screen sizes and design resolutions:
Orientation
The final essential issue is orientation.
There are two sorts of orientation:

Understanding the Strategies For Dealing with the Responsive UI
There’s two frequent approaches to creating responsive UI.
In strategy one, you retain the side ratio and scale all UI components to suit the brand new decision. Any remaining areas that don’t match the display screen gained’t be rendered and can present as a black background.
In strategy two, you regulate the side ratio and scale to suit the display screen through the use of the display screen’s side ratio. On this strategy, it is advisable to deal with two situations:
- Outline the alignment of UI components.
- Deal with the distortion of the graphical UI components.
Subsequent, you’ll discover ways to apply these two approaches in Godot.
First Strategy: Hold Side-Ratio
First, you’ll study the “hold the side ratio” strategy to dealing with responsive UI.
Open the Venture Settings and choose the Show > Window setting. Then, go to the Stretch part, set the Mode property to canvas_items and set the Side property to hold as its default setting.
