The WCK framework is something I used recently on the Blackberry Playbook version my Susie Starfish app. Moving into the world of physics is a big step for any flash dev and I feel the WCK framework is a good way to get up to speed on some of the basics.
Moving onwards I wanted to be able to appreciate how the framework works a little more so I could begin to program aspects myself through pure code in a way that was more familiar to me than the Box2DAS port. My reasoning is that I just wanted to be a little more in control for when I come to memory management and the general interactivity of the project. The following code snippet is a quick example of a box falling onto the ground and firing off the events related to such an activity.
package
{
import Box2DAS.Common.b2Base;
import Box2DAS.Dynamics.ContactEvent;
import flash.display.Sprite;
import flash.events.Event;
import shapes.Box;
import wck.WCK;
import wck.World;
public class Level1 extends Sprite
{
public var world:World;
public function Level1()
{
world = new World();
this.addChild(world);
b2Base.initialize();
var box:Box = new Box();
box.graphics.beginFill(0xff0000);
box._bubbleContacts = true;
box.graphics.drawRect(0,0,100,100);
box.graphics.endFill();
world.addChild(box);
var floor:Box = new Box();
floor._bubbleContacts = true;
floor.graphics.beginFill(0xff0000);
floor.graphics.drawRect(0,0,1000,100);
floor.graphics.endFill();
floor.type = "STATIC";
floor.y = 600;
world.addChild(floor);
box.reportBeginContact = true;
box.reportEndContact = true;
box.reportPreSolve = true;
box.reportPostSolve = true;
box.addEventListener(ContactEvent.BEGIN_CONTACT, onBlockContact, false, 0, true);
box.addEventListener(ContactEvent.END_CONTACT, onBlockContact, false, 0, true);
box.addEventListener(ContactEvent.POST_SOLVE, onBlockContact, false, 0, true);
box.addEventListener(ContactEvent.PRE_SOLVE, onBlockContact, false, 0, true);
}
protected function onBlockContact(event:ContactEvent):void
{
trace("ContactEvent");
}
}
}
