Description

Script interface for light components.

Use this to control all aspects of Unity's lights. The properties are an exact match for the values shown in the Inspector.

Usually lights are just created in the editor but sometimes you want to create a light from a script:

function Start () {
	// Make a game object
	var lightGameObject : GameObject = new GameObject("The Light");

// Add the light component lightGameObject.AddComponent(Light);

// Set color and position lightGameObject.light.color = Color.blue;

// Set the position (or any transform property) after // adding the light component. lightGameObject.transform.position = Vector3(0, 5, 0); }
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Start() {
        GameObject lightGameObject = new GameObject("The Light");
        lightGameObject.AddComponent<Light>();
        lightGameObject.light.color = Color.blue;
        lightGameObject.transform.position = new Vector3(0, 5, 0);
    }
}
import UnityEngine
import System.Collections

public class ExampleClass(MonoBehaviour):

	def Start() as void:
		lightGameObject as GameObject = GameObject('The Light')
		lightGameObject.AddComponent[of Light]()
		lightGameObject.light.color = Color.blue
		lightGameObject.transform.position = Vector3(0, 5, 0)

Functions

BroadcastMessage Calls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTag Is this game object tagged with /tag/?
GetComponent Returns the component of Type type if the game object has one attached, null if it doesn't.
GetComponentInChildren Returns the component of Type type in the GameObject or any of its children using depth first search.
GetComponentInParent Returns the component of Type type in the GameObject or any of its parents.
GetComponents Returns all components of Type type in the GameObject.
GetComponentsInChildren Returns all components of Type type in the GameObject or any of its children.
GetComponentsInParent Returns all components of Type type in the GameObject or any of its parents.
SendMessage Calls the method named methodName on every MonoBehaviour in this game object.
SendMessageUpwards Calls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
GetInstanceID Returns the instance id of the object.
ToString Returns the name of the game object.

Static Functions

Destroy Removes a gameobject, component or asset.
DestroyImmediate Destroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoad Makes the object target not be destroyed automatically when loading a new scene.
FindObjectOfType Returns the first active loaded object of Type type.
FindObjectsOfType Returns a list of all active loaded objects of Type type.
Instantiate Clones the object original and returns the clone.

Operators

bool Does the object exist?
operator != Compares if two objects refer to a different object.
operator == Compares if two objects refer to the same.
