Find component unity

Thank you for helping us improve the quality of Unity Documentation.

The purpose of that is to have the reference of that component inside our Script and to be able to use it according to our needs. For example if we want to call a function that is defined in another Script we are going to need the reference of the instance of that other Script to be able to do it. The method that we are going to see consists of using a code instruction that checks each GameObject of the hierarchy and its components until it finds the component of the type that we indicate, if there is a component of that type present in the scene the instruction will return it as the execution result and we will be able to store that component in a variable or to use it immediately to execute some simple action on the component that we found. If on the other hand there is no component of that type in any GameObject of the scene , the instruction will return Null and that could lead to an error of type NullReferenceException. To keep in mind, if we have more than one GameObject that has assigned the component we are looking for, Unity will return the first component that it finds in its register, in this case ambiguities could arise, we could obtain the reference of a different object to the one we want.

T A reference to a component of the type T if one is found, otherwise null. Gets a reference to a component of type T on the same GameObject as the component specified. The typical usage for this method is to call it from a MonoBehaviour script which itself is a type of component , to find references to other Components or MonoBehaviours attached to the same GameObject as that script. In this case you can call the method with no preceding object specified. In this case, the GameObject to which that component is attached is searched. Therefore, if there are more than one of the specified type that could match, and you need to find a specific one, you should use Component. GetComponents and check the list of components returned to identify the one you want. To find components attached to other GameObjects, you need a reference to that other GameObject or any component attached to that GameObject. You can then call GetComponent on that reference. See the Component and GameObject class reference pages for the other variations of the GetComponent family of methods.

When is this method useful?

Suggest a change. The typical usage for this method is to call it on a reference to a different GameObject than the one your script is on. Parameters type The type of Component to retrieve. This version of GetComponent is not as efficient as the Generic version above , so you should only use it if necessary. Is something described here not working as you expect it to? T A reference to a component of the type T if one is found, otherwise null. To find components attached to other GameObjects, you need a reference to that other GameObject or any component attached to that GameObject. Parameters type The name of the type of Component to search for. GetComponent because the script itself is a type of component, but the result is the same as if you had referenced the GameObject itself. The purpose of that is to have the reference of that component inside our Script and to be able to use it according to our needs.

In this article we are going to study different ways to find, from a Script, the GameObjects that are in the hierarchy in Unity. The function of this station is to return objects that are disturbed to the resting state.

In this instance, you are actually calling Component. It is recommended to use this method in some initialization function like Awake or Start. Is something described here not working as you expect it to? For some reason your suggested change could not be submitted. Suggest a change. GetComponents and check the list of components returned to identify the one you want. Is something described here not working as you expect it to? GetComponents and check the list of components returned to identify the one you want. We'll assume you're ok with this, but you can opt-out if you wish. Returns T A reference to a component of the type T if one is found, otherwise null. The typical usage for this method is to call it from a MonoBehaviour script which itself is a type of component , to find references to other Components or MonoBehaviours attached to the same GameObject as that script. Scroll to Top. To find components attached to other GameObjects, you need a reference to that other GameObject or any component attached to that GameObject. Description The non-generic version of this method. GetComponent because the script itself is a type of component, but the result is the same as if you had referenced the GameObject itself.
