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

BroadcastMessageCalls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTagIs this game object tagged with /tag/?
GetComponentReturns the component of Type type if the game object has one attached, null if it doesn't.
GetComponentInChildrenReturns the component of Type type in the GameObject or any of its children using depth first search.
GetComponentInParentReturns the component of Type type in the GameObject or any of its parents.
GetComponentsReturns all components of Type type in the GameObject.
GetComponentsInChildrenReturns all components of Type type in the GameObject or any of its children.
GetComponentsInParentReturns all components of Type type in the GameObject or any of its parents.
SendMessageCalls the method named methodName on every MonoBehaviour in this game object.
SendMessageUpwardsCalls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
GetInstanceIDReturns the instance id of the object.
ToStringReturns the name of the game object.

Static Functions

DestroyRemoves a gameobject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadMakes the object target not be destroyed automatically when loading a new scene.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsOfTypeReturns a list of all active loaded objects of Type type.
InstantiateClones the object original and returns the clone.

Operators

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