![]() Which can cause an issue with object parameters as, if you do accidentally target a prefab, instead of its clone, changing any of its variables basically changes the prefab’s default values. ![]() This happens because it’s possible to modify a prefab from code, while the game is running in play mode.Īnd while Unity will stop you from causing any serious damage, such as accidentally deleting a prefab by destroying it, for example, it’s still possible to turn components on or off, or to change data in the prefab’s scripts. Instantiating a prefab is also much safer than simply copying another object in the scene, as, if the original object is destroyed, trying to use it with the Instantiate function will cause an error.īy keeping a reference to the object prefab in your script, it’s possible to accidentally make changes to the prefab asset itself, instead of the object clone that you create. This will create a clone in the scene based on the object prefab, which can be useful for creating new objects in your game that are managed as assets in your project. To create a specific object, drag the prefab you want to instantiate into the game object reference on the script. Which is why the object that you reference when using Instantiate is referred to as the original, while the object that’s created will be marked as a clone. This basically works in the same way as manually duplicating an object in the hierarchy while the game is running in play mode, where the object that’s being created will inherit the same properties and position as the object it’s being cloned from. Like this: public GameObject objectToSpawn It works by passing in a reference to an existing game object which is then duplicated as a clone. Instantiate in Unity is a function of the Object Class that allows you to spawn new objects in your scene, from code, as your game runs. ![]() Let’s get started… How to instantiate an object in Unity How to reuse objects in Unity (using an object pool).How to instantiate an object at timed intervals.How to instantiate an object as a child.How to set the rotation & position of a new object.In this article, you’ll learn all of the different ways to use instantiate, how to clone existing prefabs and create new empty game objects, and how to use and reuse spawned objects efficiently. However, while the Instantiate function can be very straightforward, there are a lot of different ways to use it and, because creating new objects can be an extremely resource-intensive process, how you create and destroy objects can have a big impact on the performance of your game. Luckily, it can be very simple to spawn an object in Unity by using the Instantiate function, which allows you to create new objects in your scene based on existing objects in your project. While it’s possible to create big parts of your game manually, it’s extremely likely that, at some point, you’re going to need to create an object from code, as your game runs.įor example, you might want to create a bullet firing from a gun, generate waves of new enemies over time, or drop collectable objects and loot as the game is played. Chances are, a lot of the objects in your game will have been put there by you, ahead of time, in the Unity Editor.
