Tags are a powerful tool in Unity 3D that allow you to organize and categorize game objects, making it easier to find and manipulate them later on. In this article, we will cover the basics of tags in Unity, including how to create, edit, and use tags in your projects.
What are Tags?
Tags are a way to assign metadata (data about data) to game objects in Unity. They allow you to organize game objects based on their function or type, making it easier to find and manipulate them later on. For example, you might create tags for different types of enemies, vehicles, or collectibles in your game.
Creating Tags
- Select the game object you want to tag from the Hierarchy view.
- Right-click on the selected game object and choose “Tag” from the context menu.
- In the “Tag” window that appears, enter a name for your tag in the “Name” field. Make sure the name is unique and descriptive.
- Click the “Create” button to create the tag.
Editing Tags
- Select the game object you want to edit from the Hierarchy view.
- Right-click on the selected game object and choose “Tag” from the context menu.
- In the “Tag” window that appears, find the tag you want to edit and click the pencil icon next to it to open the edit dialog.
- Make any necessary changes to the tag name or description, then click the “OK” button to save your changes.
Using Tags
To use tags in Unity, you can filter game objects by their tags in the Hierarchy view. To do this, follow these steps:
- In the Hierarchy view, click on the dropdown menu next to “Filter” at the top of the window.
- Choose “Tags” from the list of filters.
- Select the tag you want to filter by from the list of available tags.
- Unity will now display only game objects that have been assigned the selected tag.
Summary
Tags are a powerful tool in Unity 3D that can help you organize and categorize your game objects. By creating and using tags, you can easily find and manipulate game objects later on, making your development process more efficient and streamlined. With this quick start guide, you should now have a solid understanding of how to use tags in Unity and be well on your way to using them effectively in your projects.
