GetComponents()

GetComponents<type>()

What if we want to get ‘n’ number of component of same type in a gameobject?

What if you have a player having its body parts distributed as Legs, Arms, body and head?

And you want to get all the mesh rendered or colliders of the gameobjects?

In this type of scenarios we will use GetComponent<type> insist of GetComponents<type>.

GetComponents is majorly use when we have a hierarchy like structure of gameobjects each having the component to be used.

So let’s start and firstly make a model of player in unity using simple 3D objects.

Like This:

 

Getting Components

Step1: Add more than 1 box Collider to gameobject named as player.

Step2: Create a script and attach it to your player gameobject.

Step3: Write the following code:

Step4: Save the script and scene you will notice a BoxColl named field will appear with an arrow sign with label size in it. This are arrays which are used to store multiple values of same time.

Run the game and it will automatically get filled by the desired Box Colliders.

Getting Components in Parent

When we want to get the components of Parent gameobject we will do it as follows

Step1: Write the following code:

Save the script and run the game you will notice that colliders are filled starting from the parent gameobject "leftleg" than the parent.

Getting Components in children

When we want to get the components in children gameobject we will do it as follows:

Step1: Write the following code:

Save the script and run the game you will notice that 6 colliders are filled starting from the parent gameobject which is Player in our case.

In Next Post we will learn about getting properties of the component and setting properties.
