To add a component:

1. Adding components dynamically

1 // dynamically add related components or scripts 2 rigidbody RB = gameobject.addcomponent<rigidbody> ( );

2. Adding components by extension Editor [Requirecomponent]

Note: The code executed by the extended editor must be in the editor state

For example, to add a rigid component Rigidbody

        [Requirecomponent (typeof (Rigidbody)])  adds a rigid body when mounting a        script, not the public class that is added at execution time Newbehaviourscript2:monobehaviour {}

Execute in Edit state, add a rigid body component when adding a script
