You can use prefabsAn asset type that allows you to store a GameObject complete with components and properties. The prefab acts as a template from which you can create new object instances in the scene. More info
See in Glossary to reuse 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
See in Glossary configurations in multiple places in a sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary or across different scenes in your project. The prefab system keeps all copies of a GameObject in sync, so when you make changes to a prefab asset, Unity updates all instances of that prefab automatically. This allows you to update multiple GameObjects without needing to edit each copy individually.
Common uses for prefabs include:
You can nest prefabs inside other prefabs to create complex hierarchies of objects that you can edit at multiple levels. However, not all prefab instances need to be identical. You can override settings on individual prefab instances if you want some to differ from others. You can also create prefab variants to group a set of overrides into different variations of a prefab.
Prefabs are also useful when you want to instantiate GameObjects at runtime that don’t exist in your scene at the start. For example, you might spawn in-game items, special effects, projectiles, or NPCs during gameplay.
When you select a prefab, its InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary window contains an Asset Preview pane which displays a preview of the prefab. If the prefab is smaller than 8 MB, the preview is interactive, and you can rotate the prefab in the pane.
If the prefab is larger than 8 MB, the Asset Preview displays a static image by default. To view an interactive preview for larger prefabs, click anywhere inside the Asset Preview pane.
