Javascript Box2DWeb-在世界范围内添加和删除车身

我在Box2D中有以下代码，我想将我的动态身体移动到鼠标单击的位置。此外，在将来我希望能够删除动态实体，但我无法找到任何与world.DeleteBody（…）等效的内容。请帮忙

var world;
var   b2Vec2 = Box2D.Common.Math.b2Vec2
        ,   b2BodyDef = Box2D.Dynamics.b2BodyDef
        ,   b2Body = Box2D.Dynamics.b2Body
        ,   b2FixtureDef = Box2D.Dynamics.b2FixtureDef
        ,   b2Fixture = Box2D.Dynamics.b2Fixture
        ,   b2World = Box2D.Dynamics.b2World
        ,   b2MassData = Box2D.Collision.Shapes.b2MassData
        ,   b2PolygonShape = Box2D.Collision.Shapes.b2PolygonShape
        ,   b2CircleShape = Box2D.Collision.Shapes.b2CircleShape
        ,   b2DebugDraw = Box2D.Dynamics.b2DebugDraw
        ;
var canvas = document.getElementById("canvas");
var context = canvas.getContext("2d");

var mouseX, mouseY, isMouseDown;
var bBallBody, bBallbodyDef;

function init() {
    world = new b2World(
           new b2Vec2(0, 10)    //gravity
        ,  true                 //allow sleep
    );
    setupWorld() ;
    //setup debug draw
    var debugDraw = new b2DebugDraw();
        debugDraw.SetSprite(document.getElementById("canvas").getContext("2d"));
        debugDraw.SetDrawScale(1.0);
        debugDraw.SetFillAlpha(0.3);
        debugDraw.SetLineThickness(1.0);
        debugDraw.SetFlags(b2DebugDraw.e_shapeBit | b2DebugDraw.e_jointBit);

    world.SetDebugDraw(debugDraw);
    window.setInterval(update, 1000 / 60);
  };

  function setupWorld() {
      setupGround();
      addBouncingBall();
  }

  function setupGround() {
     var fixDef = new b2FixtureDef;
     fixDef.density = 1.0;
     fixDef.friction = 0.5;
     fixDef.restitution = 0.2;
     var bodyDef = new b2BodyDef;
     //create ground
     bodyDef.type = b2Body.b2_staticBody;
     bodyDef.position.x = 300;
     bodyDef.position.y = 400;
     fixDef.shape = new b2PolygonShape;
     fixDef.shape.SetAsBox(290, 10);
     world.CreateBody(bodyDef).CreateFixture(fixDef);
  }

  function addBouncingBall() {
     var fixDef = new b2FixtureDef;
     fixDef.density = 1.0;
     fixDef.friction = 1.0;
     fixDef.restitution = 0.1;
     var bBallbodyDef = new b2BodyDef;
     bBallbodyDef.type = b2Body.b2_dynamicBody;
     fixDef.shape = new b2CircleShape(Math.random() + 30);
     bBallbodyDef.position.x = Math.random() * 300;
     bBallbodyDef.position.y = Math.random() * 300;
     bBallBody = world.CreateBody(bBallbodyDef).CreateFixture(fixDef);  
     console.log(bBallBody.m_body.GetPosition().x);

  };

  document.addEventListener("mousedown", handleMouseMove, true);

  function handleMouseMove(e) {
      isMouseDown = true;
      mouseX = e.clientX;
      mouseY = e.clientY;
  };

  function update() {

     if(isMouseDown)
      {
          for (b = world.GetBodyList() ; b; b = b.GetNext()) {
              if (b.GetType() == b2Body.b2_dynamicBody) {
                   console.log(b.x, b.y);
                   b.x = 100;
                   b.y = 100;
                   }
                   }
      isMouseDown = false; 
      } 
       world.Step(1 / 60, 10, 10);
       world.DrawDebugData();
       world.ClearForces();
  };

更新：

从世界中删除对象的操作如下：

创建一个计时器来计划删除对象

   window.setInterval(removeObjScheduledForRemoval, 1000/90);

在数组中收集要删除的对象

   var bricksScheduledForRemoval = Array();
   var index = -1;
   function removeObjScheduledForRemoval()
   {
     for(var i = 0; i <= index; i++){
    world.DestroyBody(bricksScheduledForRemoval[i]);    
    bricksScheduledForRemoval[i] = null;    
      }
 bricksScheduledForRemoval = Array();
     index = -1;
    }

var brickscheduledforremoval=Array（）；
var指数=-1；
函数removeObjScheduledForRemoval（）
{
对于（var i＝0；i），BOX2DWeb的文档远不如原来的C版本那么全面，所以考虑搜索“Box 2D”而不是“Box 2DWeb”。。此外，查看并搜索某些方法的拼写可能会有所帮助。或者只查看box2d flash文档。基本上，box2dweb具有方法
DestroyJoint
和
DestroyBody

对于更多的注意事项，这可能会很有帮助：
您可以像本游戏示例那样删除主体或将静态主体更改为动态主体。

Box2dweb具有removebody或changeBodyType选项，请参阅其源代码。
嘿，谢谢，Box2dweb严重缺乏文档，对此我感到头疼。了解了一些基本工作流，在中发表了相关博客。希望有人会发现它有用：）嘿，谢谢，Box2DWeb严重缺乏文档，一直让我头痛不已。了解了一些基本的工作流程，并在中发表了关于它的博客。希望有人会发现它有用：）上面的链接页面引发了以下错误：
