Updated to include improved prefab features - Nested Prefabs and Prefab Variants added in 2018. The player’s main character - the player prefab might be placed at the starting point on each level (separate Scenes) of your game. We’ve made several improvements to the Prefab system based on your feedback In the latest Unity 2022.2 Tech Stream release, you can now easily replace one o. Projectiles - for example a pirate’s cannon might instantiate a cannonball Prefab each time it is fired. They may differ (using overrides) in the speed they move, or the sound they make. Non-player characters (NPCs) - for example a certain type of robot may appear in your game multiple times, across multiple levels.
With that out of the way: Setup: I have a component SpriteList that lives on a prefab SpritesPrefab. Some common examples of Prefab use include:Įnvironmental Assets - for example a certain type of tree used multiple times around a level (as seen in the screenshot above). Saving a nested prefab via script in Unity Ask Question Asked today today Viewed 2 times 0 For context, I'm using Unity 2019.4.40 so a few of the PrefabUtility changes are not available to me. You should also use Prefabs when you want to instantiate GameObjects at runtime that did not exist in your Scene at the start - for example, to make powerups, special effects, projectiles, or NPCs appear at the right moments during gameplay. The Apply All button in the Overrides drop-down window only allows applying the override to the outer Prefab - the Table in. If on this instance, a property on Vase is overridden, there are multiple Prefabs this override could be applied to: the Vase or the Table. You can also create variants of Prefabs which allow you to group a set of overrides together into a meaningful variation of a Prefab. A ‘Vase’ Prefab nested inside a ‘Table’ Prefab. You can override settings on individual prefab instances if you want some instances of a Prefab to differ from others. However, this does not mean all Prefab instances have to be identical. You can nest Prefabs inside other Prefabs to create complex hierachies of objects that are easy to edit at multiple levels. When Unity imports a Model from a 3D modeling application such as Autodesk® Maya®, Unity creates a Model Prefab, which is a read-only representation of the FBX files contents. This is better than simply copying and pasting the GameObject, because the Prefab system allows you to automatically keep all the copies in sync.Īny edits that you make to a Prefab Asset are automatically reflected in the instances of that Prefab, allowing you to easily make broad changes across your whole Project without having to repeatedly make the same edit to every copy of the Asset. In Unity, Nested Prefabs allow you to create Prefabs inside other Prefabs, and Prefab Variants allow you to save a variation on an existing Prefab. When you want to reuse a GameObject configured in a particular way – like a non-player character (NPC), prop or piece of scenery – in multiple places in your Scene, or across multiple Scenes in your Project, you should convert it to a Prefab.
The Prefab Asset acts as a template from which you can create new Prefab instances in the Scene. Unity’s Prefab system allows you to create, configure, and store a GameObject complete with all its components, property values, and child GameObjects as a reusable Asset.
