UI Tool Kit is the newly introduced user interface version in the latest Unity Engine. It is designed to enhance performance and ensure long-term improvements. It can also accommodate advanced use cases involving HTML and CSS. The Unity UI caters to game user interfaces with a moderate complexity. It minimizes the need for extensive updates across user interfaces, game projects, or game versions. The UI Tool Kit enhances the experience over time. This happens as you update the game project version in Unity. It offers significant advantages over its predecessor in usability. It also brings improvements and version compatibility. Unlike Unity UI, which is managed through the package manager, the UI Tool Kit is directly integrated with the Unity Engine. It is part of the engine version itself. It is not managed through the package manager. This integration guarantees that it will also be updated alongside the latest available Unity versions.

The UI Tool Kit supports HTML. It is an excellent choice for web developers looking to integrate this language. This tool kit is readily available for use. Additionally, CSS is utilized in the editor for naming and renaming user interface objects. These UI objects can be referenced within C# scripting. This occurs during programming on the job system. It can also occur on the Mono Behaviour main thread. Register the object names during initialization. This allows you to access them in C# scripting. You can call functions to change string text for labels displayed on screen. HTML can also facilitate the input for various objects like buttons, inputs, text fields, and toggles in scripts. For manual actions, you can drag objects within the UI Tool Kit editor to the desired transform flex. Web developers will find the scripting aspect more familiar.

At the moment I’m working with the UI Toolkit. The tools are still in early access. This means Unity developers will need to update their game projects following any new updates to the Unity game engine. The UI Toolkit is relatively new. It requires further enhancements. Yet, it holds promise for the future of the Unity game engine, especially beyond just the Unity user interface. There are several issues with the UI Toolkit. These issues affect how it interacts with the Unity user interface. This is particularly evident in the simulation or farming game. The dialog for the farm pet character necessitates game object instantiation in the world. Updating its world position is also required accordingly. This challenge has made me realize something important. Utilizing the Unity user interface alongside the UI Toolkit is crucial for effectively addressing these issues. I’m still uncertain about the role of the UI Toolkit, like updating label text. I do not know how it should reflect changes in world position during development. Additionally, the UI Toolkit cannot be destroyed post-instantiation unless the Unity user interface is employed. Let us look at the screenshots. They demonstrate the User Interface from both the previous and the new simulation or farming game. I have developed these interfaces.

Screenshot 1 displays the canvas scaler for the user interface in the main menu, allowing for screen resizing to different dimensions. At the top is the Unity user interface, while the bottom showcases the User Interface Tool Kit. Many functions are quite comparable between the two, particularly concerning reference resolution and scale mode. To integrate the User Interface Tool Kit, you must include the UI Document scripts and configure the panel settings, whereas for the Unity user interface, you need to add the canvas scaler along with the canvas.

Screenshot 2 displays the user interface buttons for both the UI Toolkit at the bottom and the Unity user interface at the top. To modify the transform of the Unity user interface, utilize the Rect Transform by adjusting the position, rotation, and scale within the hierarchy. The button interface can be configured either manually or through scripts to trigger an event when pressed. You can add an image to the button by selecting a specific sprite. The bottom image illustrates the UI Toolkit, which features attributes that allow for text manipulation on the button. The stylesheet uses CSS syntax, where you can specify the name of the hierarchy button object to be referenced in C# scripting, such as enabling or disabling the object. The position setting allows for transforming the location on the screen, while size adjusts the scaling of the user interface, and background enables the insertion of an image for the button. The UI Toolkit functions similarly, particularly the button, when compared to the Unity user interface.
