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. When is this method useful? This method is effective when the component we are looking for is unique in the scene, if there is more than one component of the same type there is no guarantee of finding precisely the one we are looking for.

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.

It is not recommended to use this method inside update functions like Update because they imply to traverse in the worst case the whole hierarchy of the scene, find component unity.

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. The 5 objects are declared as private and are serialized, so they appear in the inspector as shown in the following figure. In the Start method there is a call to 5 methods that will find the references. The methods are incomplete. Our goal is to complete them and discover different ways to find the references. As you can see in figure 4, all objects are defined as private and serialized, but this is more than anything for us to see in the inspector, how to start the game we find the reference.
