Public GameObject prefab // This is our prefab object that will be exposed in the inspector Public class PopulateGrid : MonoBehaviour
Open the script in your IDE of choice. On the Add Component window, type PopulateGrid and create a new C# script. Click the “Content” object in the hierarchy and choose add component. Now, we want to create a C# script that will handle populating our grid with image prefabs. You can delete the Image from the hierarchy window. Once you’ve done that, you should see the “Image” prefab listed in the Assets folder of your project explorer. Drag and drop the Image object from the hierarchy into your project explorer to create a prefab. The image will just look like a white rectangle on your screen. We’ll leave the Image settings default. Now, we want to create a UI image that we can populate our grid with. If you want to know more about the Content Size Fitter, refer to Unity’s documentation. This will allow the height of our Content Rect to change dynamically if the number of UI elements populating the grid exceeds the current Rect transform’s height boundary. On the Content Size Fitter, set the “Vertical Fit” option to “Preferred Size”. On the Grid Layout Group script, change the X and Y spacing to 5. Now, your content object should have the following components: In the Add Component window, type “Content Size Fitter” and add the Content Size Fitter component. Add another component to the Content object. Type “GridLayoutGroup” and press “ENTER”. With the Content object selected, go into the Inspector and click “Add Component”. The scroll view works by allowing you to scroll vertically or horizontally in the Content object Rect area, even if that area is larger than the area of the scroll view. You can modify the size of this Rect by using the Rect tool to change the width and height. The Content object is what the scroll view scrolls through. The content object is where we will be attaching our GridLayoutGroup component. Then expand the Viewport hierarchy to reveal the Content object. Depending on your game’s aspect ratio, you may want to adjust this to your liking. I am going to resize my ScrollView Rect to be 400×400. If you are curious about the details of these options, refer to the Unity Documentation. You’ll notice the ScrollView object has a custom Scroll Rect script attached to it with a number of options. Right-click on the newly created Canvas in the Hierarchy window and choose UI → Scroll View. With your new project open, create a new Canvas object from the Game Object→ UI → Canvas. You do not need to import any assets unless you want to. #Unity 2019 tutorial how to#
I will not be covering basic concepts, such as creating a project, adding Game Objects, or how to use the Inspector. A Scroll View component in Unity is similar.įirst, I am going to assume you have a basic understanding of Unity. You can scroll up or down and reveal more information by doing so. It acts as a sort of UI panel that you can store UI elements on and scroll through them using a mouse or touch input. Scrolling Window: A scrolling window is a component that’s built into Unity. If you want a more general tutorial about creating UI’s in Unity, refer to my blog post on the basics of creating a UI in Unity 3D. The goal is to create a window that the user can scroll up and down, which contains a grid layout of a basic image. In this post, we’ll look at how you can use Unity 3D to create a scrolling window and a grid-based layout for UI elements. In a video game, a UI makes it easier for you to interpret data (hit points, currency, items), interact with a visual world, or alter video and sound settings, for example.

Without a UI, the software would have to be used with nothing but text and command lines. A UI is one of the most important features of software because it is the element of your program that the user will usually be interacting with the most. A concept that’s often talked about in software development and game design is User Interface, commonly known as “UI”.
