Unity Script Reference – GameObject.AddComponent

GameObject.AddComponent

function AddComponent (className : string) : Component

Description

Adds a component class named className to the game object.

Use this function to change behaviour of objects on the fly. You can also add script to game objects by passing in the name of the script class.

Some components require other components to exist in the same game object as well. This function automatically adds any required components as well eg. if you add a HingeJoint this will automatically add a Rigidbody as well.
