Después de escribir este post mi buen amigo Iván aportó una grandísima idea, un diseño y me dió más tareas para el tren, mi lado friki sentía cosquillas por hacerlo con la API de dibujo de Flash, pero para variar un poco en esta ocasión lo he hecho en ActionScript 2.0 y en ActionScript 3.0 que realmente no es tan distinto para los que ya programan en AS2.

INTRODUCCIÓN

La idea es poner un coche en el circuito que ya hicimos en el anterior post, así que simplemente con rectángulos lo vamos a hacer. Para esto haremos uso de la API de dibujo de Flash en AS2 y AS3, las diferencias son pequeñas y en ocasiones grandes, pero con un poco de imaginación haremos que se parezcan más, :P.

DESARROLLO

ActionScript 3.0

En ActionScript 3.0 utilizaremos los métodos beginFill y drawRect de la clase Graphics.

ActionScript 2.0

En ActionScript 2.0 no tenemos una clase Graphics y menos aún el método drawRect, pero la solución es fácil, hacemos una función o método que haga lo mismo y listo :D.

function drawRect(_mc:MovieClip, _nX:Number, _nY:Number, _nW:Number, _nH:Number):Void
{
	_mc.moveTo(_nX, _nY);
	_mc.lineTo(_nX + _nW, _nY);
	_mc.lineTo(_nX + _nW, _nY + _nH);
	_mc.lineTo(_nX, _nY + _nH);
	_mc.lineTo(_nX, _nY);
}

CÓDIGO COMPLETO

A continuación el código en ActionScript 3.0:

package
{
	import flash.display.MovieClip;
	import flash.display.Shape;
	import flash.display.Sprite;
	import flash.events.Event;

	public class Car extends MovieClip
	{

			//Cristal trasero

			this.structure.graphics.drawRect(49, 7, 293, 68);

			//Retrovisor izquierdo
			this.structure.graphics.beginFill(0xFF0000);
			this.structure.graphics.drawRect(0, 65, 42, 21);

			this.structure.graphics.beginFill(0x70A9FE);
			this.structure.graphics.drawRect(3, 68, 35, 15);

			//Matrícula
			this.bar.graphics.beginFill(0xFFFFFF);
			this.bar.graphics.drawRect(157, 128, 78, 20);

			this.car.addChild(this.wheels);

			this.car.scaleX = 0.5;

		private function doOnEnterFrame(_oEvent:Event):void

Out Run

En un proyecto que participé hace poco tuvimos que hacer un circuito de carreras  y aunque parece increíble no encontré algo por ahí que me sirviera de base, así que al final me lo tuve que cocinar.

Dentro de los requisitos técnicos tenía que ser para Flash Player 7, con lo cual no podía utilizar la Clase BitmapData de AS2 y muchísimo menos utilizar AS3, así que la cosa se ponía más chunga, pero bueno, sino donde queda la gracia. :P

Teníamos en la mente el mítico juego Out Run y queríamos conseguir algo como eso. Aunque durante la investigación vimos las maravillas de AS3 o las posibilidades al utilizar la Clase BitmapData con el motor del modo 7, pero nada, donde manda capitán no manda marinero, así que a buscarse la vida.

El resultado fué el siguiente, bueno, este realmente no es, esta es una versión lite que programé en mis mañanas de tren, jejeje. Mi lado friki me obligó a hacerlo todo con programación, así que el código se puede copiar, pegar y compilar sin problema.

NOTA:

Utilizo la TweenLite así que no funciona tal cual, hace falta tener la librería TweenLite. :P
