Deactivating GameObjects

You can mark a GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info

In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

See in Glossary and uncheck the checkbox next to the GameObject’s name (see image below), or use the activeSelf property in script.

Deactivating a parent GameObject

When you deactivate a parent GameObject, You also deactivate all of its child GameObjects.

The deactivation overrides the activeSelf setting on all child GameObjects, so Unity makes the whole hierarchy inactive from the parent down. This does not change the value of the activeSelf property on the child GameObjects, so they return to their original state when you re-activate the parent.

Note: This means that you can’t determine whether or not a child GameObject is currently active in the Scene by reading its activeSelf property, because even though it is set as active, one of its parents might be set as inactive.

Instead, if you need to determine whether it’s currently active in the scene, you should use the activeInHierarchy property, which takes the overriding effect of its parents into account.
