andengine游戏引擎实用篇-box2d与瓦片地图的结合使用
1）加载瓦片地图

 //加载TMXtry {final TMXLoader tmxLoader = new TMXLoader(this,this.mEngine.getTextureManager(), TextureOptions.NEAREST,null);this.mTMXTiledMap = tmxLoader.loadFromAsset(this,"sence"+leave.getInt("leave", 1)+".tmx");} catch (final TMXLoadException tmxle) {Debug.e(tmxle);}//将每一层TMXLayer加载到scene中for (int i = 0; i < this.mTMXTiledMap.getTMXLayers().size(); i++) {TMXLayer layer = this.mTMXTiledMap.getTMXLayers().get(i);mScene.attachChild(layer);}

2）创建物理世界

this.mPhysicsWorld = new FixedStepPhysicsWorld(30, new Vector2(0, 80),true, 8, 1);

3）创建主要人物，屏幕更新方式注册为按照物理世界中的方式更新

final AnimatedSprite player = new AnimatedSprite(centerX-200, centerY-100,this.mPlayerTextureRegion);//this.mBoundChaseCamera.setChaseEntity(player);final FixtureDef playerFixtureDef = PhysicsFactory.createFixtureDef(0,0, 0.5f);mPlayerBody = PhysicsFactory.createBoxBody(this.mPhysicsWorld, player,BodyType.StaticBody, playerFixtureDef);this.mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(player, mPlayerBody, true, false) {@Overridepublic void onUpdate(float pSecondsElapsed) {super.onUpdate(pSecondsElapsed);mBoundChaseCamera.updateChaseEntity();//相机更新方式}});physicalmap.put(mPlayerBody, player);mPlayerBody.setUserData("mPlayerBody");mScene.attachChild(player);

4）读取每个瓦片，与物理世界结合

public void creatBox(TMXTiledMap map){for (final TMXObjectGroup group : this.mTMXTiledMap.getTMXObjectGroups()) {if (group.getTMXObjectGroupProperties().containsTMXProperty("box","true")) {//如果瓦片地图中图块的键为“box”，值为“true”for (final TMXObject object : group.getTMXObjects()) {final Sprite box = new Sprite(object.getX(), object.getY(),this.mBoxTextureRegion);//创建皮肤final FixtureDef boxFixtureDef = PhysicsFactory.createFixtureDef(0, 0, 1f);//连接器final Body boxBody=PhysicsFactory.createBoxBody(this.mPhysicsWorld, box,BodyType.DynamicBody, boxFixtureDef);//刚体boxBody.setUserData("boxBody");//为刚体设置值，供碰撞检测时使用physicalmap.put(boxBody, box);//供碰撞检测时使用,通过键找到值this.mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(box, boxBody, true, false));//注册到物理世界中mScene.attachChild(box);//将皮肤天剑到sence中}}}}
