public function AddComponent(className: string): Component;
public Component AddComponent(string className);

Parameters

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.

	// Adds the sphere collider to the game object
	var sc : SphereCollider;
	sc = gameObject.AddComponent ("SphereCollider");
	// Adds the sphere collider to the game object
	SphereCollider sc = gameObject.AddComponent("SphereCollider") as SphereCollider;

public function AddComponent(componentType: Type): Component;
public Component AddComponent(Type componentType);

Parameters

Description

Adds a component class of type componentType to the game object. C# Users can use a generic version.

	// Adds the sphere collider to the game object
	var sc : SphereCollider;
	sc = gameObject.AddComponent (SphereCollider);
	// Adds the sphere collider to the game object
	SphereCollider sc = gameObject.AddComponent<SphereCollider>();

Note that there is no RemoveComponent(), to remove a component, use Object.Destroy.


public function AddComponent(): T;
public T AddComponent();

Description

Generic version. See the Generic Functions page for more details.
