BuenAS:
Más que este ejemplo (que me suena de algo
) si lo que quieres es que interactúen las burbujas, echa un vistazo a:
Box2DBox2D descargar código y ejemplosy para facilitar un poco su utilización:
Quick Box2Dya que además de arrastrar las burbujas necesitarás un motor de físicas que las haga interartuar.
Un saludo.
Lukànicos le he tomado la palabra he descargado una libreria, cuya clase comienzo a entender pero aun tengo muchas dudas, podria por favorrrrrr ayudarme y explicarme un poco mas de su funcionamiento por favooor.
la clase en cuestion es:
Código :
package{
import flash.display.Sprite;
import flash.events.Event;
// Classes used in this example
import Box2D.Dynamics.*;
import Box2D.Collision.*;
import Box2D.Collision.Shapes.*;
import Box2D.Common.Math.*;
public class HelloWorld extends Sprite{
public function HelloWorld(){
// Add event for main loop
addEventListener(Event.ENTER_FRAME, Update, false, 0, true);
// Creat world AABB
var worldAABB:b2AABB = new b2AABB();
worldAABB.lowerBound.Set(-100.0, -100.0);
worldAABB.upperBound.Set(100.0, 100.0);
// Define the gravity vector
var gravity:b2Vec2 = new b2Vec2(0.0, 10.0);
// Allow bodies to sleep
var doSleep:Boolean = true;
// Construct a world object
m_world = new b2World(worldAABB, gravity, doSleep);
// set debug draw
/*var dbgDraw:b2DebugDraw = new b2DebugDraw();
var dbgSprite:Sprite = new Sprite();
addChild(dbgSprite);

}Quisiera poder agregar otros Mc y a traves de un array introducirlos a la escena de manera aleatoria a traves del evento mouseclick, por favorrrrrr despeje mis dudas y disculpe tantas molestias.
