How to add and customize a button in Unity?

Buttons are essential for creating interactive user interfaces in Unity. Learning how to add and customize buttons will allow you to drastically improve the user experience in your game or application. In this session, we explore how to create a button using Text Mesh Pro, make it more attractive by changing colors, and handle different visual states.

To start creating a button, follow these steps:

1. Right-click on your UI object within Unity.
2. Select the "Button with Text Mesh Pro" option from the UI menu.
3. A new button will appear with a default text. You can customize this text by setting its size to 200, enabling "Auto Size" and using bold text to make it stand out.

What settings does a button have?

The button component includes several settings that you can adjust:

• Interactable: allows you to enable or disable the interaction of the button. This is useful, for example, to display disabled buttons on locked levels.
• Transitions: A button has different visual states that indicate when the mouse is over it, when it is selected or pressed. You can change these colors to make the button react to the user in a visually appealing way.
• Button image: Unity uses a default image, but you can customize it by replacing it with your own image. Adjust the properties of the image element to display it as you wish.
• Fade: Adjust the fade duration between state changes.

Navigation settings are vital when working with multiple buttons and using arrow keys to navigate between them.

How does Unity's event system work?

Working with events is critical when a button is clicked. In Unity, you can easily configure what action will occur on a click:

1. Select the button and access the OnClick section.
2. Press the "More" button to add a new event.
3. Assign an object and select the function you want to execute when it is clicked.

For example, you can set a button to deactivate a GameObject when clicked. For this, use the SetActive function and test the behavior when running the scene.

Practical tips and recommendations

• Experiment with different transition modes such as Sprite Swap or animation mode if you are looking for more advanced effects.
• Use color settings to highlight critical or informative buttons.
• Implement the automatic navigation system to improve accessibility, especially when you want users to navigate with a keyboard.
• Test different button configurations and share your results with the community for feedback.

Keep exploring and customizing these features to enrich your projects. The world of Unity development is vast, and every tweak is a learning opportunity, so keep on creating!
