Add GameObjects to your scene
Select Add (+) to bring up the menu to add new GameObjects to your scene. You can choose from:
Property | Description |
|---|---|
| Empty Object | A blank GameObject, useful for grouping or as a starting point. |
| Primitives | Basic 3D shapes (Cube, Sphere, Capsule, Cylinder, Plane, Quad) for building or prototyping your scene. |
| UI | Add UI Canvas, Button, Text, InputField or Image elements to your scene. |
Hierarchy list
The list of GameObjects in the Hierarchy panel provides several useful features to help you manage and organize your GameObjects.
Scene visibility and selectability
If your scene has many objects, it can be difficult to manage all the items. Use these controls to make your workflow easier:
Property | Description |
|---|---|
| Toggle selectability | Locks an asset so you can’t select it in the Scene view. Useful to protect important objects from accidental edits. |
| Toggle visibility | Hides or shows objects in the Scene view without affecting their visibility during Play mode. This helps you focus on specific parts of your scene or work with complex projects. |
Select objects
Select the names of the GameObjects in the list to open their properties in the Inspector panel, or to manipulate the object in the Scene view.
Right-click the object(s) in the list to access further actions via the context menu.
Hierarchy editing
You can freely rearrange the internal hierarchy of imported 3D models. For example, you can reparent parts, move child objects to different positions, delete individual child objects, and create new child objects (such as empty objects or primitives) within a model’s hierarchy.
Parent your objects
Unity Studio uses a parent-child hierarchy to help you organize your scene. When you drag one GameObject onto another in the Hierarchy, you make it a child of the target object. This means:
- If you move, scale, or rotate the parent, it affects all its children.
- You can nest GameObjects for easier organization and transformation.
This is especially helpful if you want to keep related objects together. For example, to group parts of a machine or elements of a User Interface (UI).
