You can create a prefab by selecting Asset > Create Prefab and then dragging an object from the scene onto the “empty” prefab asset that appears. However, although its behaviour is superficially similar, the asset is not a prefab, so you won’t be able to add components to it or make use of the other prefab features described below. Note: When you drag an asset file (eg, a Mesh) into the scene, it will create a new object instance and all such instances will change when the original asset is changed. Any edits made to a prefab asset are immediately reflected in all instances produced from it but you can also override components and settings for each instance individually. The prefab acts as a template from which you can create new object instances in the scene.
Generally, you want all instances of a particular object to have the same properties, so when you edit one object in the scene, you would prefer not to have to make the same edit repeatedly to all the copies.įortunately, Unity has a Prefab asset type that allows you to store a GameObject object complete with components and properties. Simply copying the object will certainly produce duplicates but they will all be independently editable. This can create problems, however, when you have an object like an NPC, prop or piece of scenery that is reused in the scene several times. It is convenient to build a GameObject in the scene by adding components and setting their properties to the appropriate values.
