- Closing: The ultimate model of the responsive UI, which you’ll be able to run and play instantly.
As well as, this tutorial requires you to have primary data of Godot Engine and GDScript. The next tutorials can get you up to the mark:
File Overview

The starter model doesn’t assist responsive dealing with, and chances are you’ll discover some UI issues while you resize the window.
You’re objective is to show this easy 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 could have totally different gadgets with totally different display resolutions.
Listed here are some widespread display resolutions on totally different platforms:
- Desktop: 1920×1080, 1366×768, 1280×1024, 1024×768
- Cellular: 667×375, 736×414, 800×360, 844×390

- UI parts could seem too small.
- UI parts are positioned off the display.
- UI parts are unfilled or overlapping.
Responsive UI goals for a constant, gratifying expertise on all screens.
Fundamental Data of Person Interface Design
Earlier than you construct a responsive UI, it’s essential to be taught 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 putting bins on a canvas.
These bins are the UI parts, like labels and buttons. The canvas is your sport display. Design decision refers back to the goal dimensions of the canvas, which helps decide the width and top of UI parts to fulfill the design necessities.
Side Ratio
Side ratio is one other essential consider UI design. It’s calculated by dividing the width of the display by its top. By evaluating the side ratios of your design and the display, you’ll know if the display is wider, narrower, or the identical.
Right here’s a comparability of varied display sizes and design resolutions:
Orientation
The final essential issue is orientation.
There are two sorts of orientation:
- Portrait: The display width is shorter than the display top.
- Panorama: The display width is longer than the display top.
Selecting the proper orientation within the early growth section is essential. It dramatically impacts the consumer interface design. For instance, desktop-first video games sometimes use panorama orientation, whereas it’s widespread for mobile-first video games to make use of portrait orientation.
Understanding the Strategies For Dealing with the Responsive UI
There’s two widespread approaches to creating responsive UI.
In method one, you retain the side ratio and scale all UI parts to suit the brand new decision. Any remaining areas that don’t match the display received’t be rendered and can present as a black background.
In method two, you modify the side ratio and scale to suit the display through the use of the display’s side ratio. On this method, you should deal with two situations:
- Outline the alignment of UI parts.
- Deal with the distortion of the graphical UI parts.
Subsequent, you’ll learn to apply these two approaches in Godot.
First Strategy: Maintain Side-Ratio
First, you’ll be taught the “hold the side ratio” method 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.
When rerunning the sport, you’ll see that the UI is aware of the display measurement change.
Right here’s the consequence:
The UI is now now not caught to the top-left nook of the display.
Nevertheless, if you happen to hold transferring in the identical course, you’ll discover the participant character strikes out of view.
You’ll learn to tackle this situation shortly.
