我不知道该怎么做，contactlistener已经不再适用了。
问题是我首先使用Simpleleveloader来加载我的精灵 - 在此期间Contactlistener没有问题。
但后来我想将Simpleleveloader改为我自己写的东西（因为我想要无穷无尽的级别，而不是预先制作的xml），而且这里的联系人听众不会工作！
以下是Leveloader： 代码：
private void loadiLevel(int levelID)
{
final SimpleLevelLoader levelLoader = new SimpleLevelLoader(vbom);
final FixtureDef FIXTURE_DEF = PhysicsFactory.createFixtureDef(0, 0.01f, 0.5f);
camera.setBounds(0, 480, 2500, 40); // here we set camera bounds
camera.setBoundsEnabled(true);
levelLoader.registerEntityLoader(new EntityLoader<SimpleLevelEntityLoaderData>(LevelConstants.TAG_LEVEL)
{
public IEntity onLoadEntity(final String pEntityName, final IEntity pParent, final Attributes pAttributes, final SimpleLevelEntityLoaderData pSimpleLevelEntityLoaderData) throws IOException
{
final int width = SAXUtils.getIntAttributeOrThrow(pAttributes, LevelConstants.TAG_LEVEL_ATTRIBUTE_WIDTH);
final int height = SAXUtils.getIntAttributeOrThrow(pAttributes, LevelConstants.TAG_LEVEL_ATTRIBUTE_HEIGHT);
return GameScene.this;
}
});
levelLoader.registerEntityLoader(new EntityLoader<SimpleLevelEntityLoaderData>(TAG_ENTITY)
{
public IEntity onLoadEntity(final String pEntityName, final IEntity pParent, final Attributes pAttributes, final SimpleLevelEntityLoaderData pSimpleLevelEntityLoaderData) throws IOException
{
final int x = SAXUtils.getIntAttributeOrThrow(pAttributes, TAG_ENTITY_ATTRIBUTE_X);
final int y = SAXUtils.getIntAttributeOrThrow(pAttributes, TAG_ENTITY_ATTRIBUTE_Y);
final String type = SAXUtils.getAttributeOrThrow(pAttributes, TAG_ENTITY_ATTRIBUTE_TYPE);
final Sprite levelObject;
if (type.equals(TAG_ENTITY_ATTRIBUTE_TYPE_VALUE_PLATFORM1))
{
levelObject = new Sprite(x, y, resourcesManager.platform1_region, vbom);
PhysicsFactory.createBoxBody(physicsWorld, levelObject, BodyType.StaticBody, FIXTURE_DEF).setUserData("platform1");
}
else if (type.equals(TAG_ENTITY_ATTRIBUTE_TYPE_VALUE_PLATFORM2))
{
levelObject = new Sprite(x, y, resourcesManager.platform2_region, vbom);
final Body body = PhysicsFactory.createBoxBody(physicsWorld, levelObject, BodyType.StaticBody, FIXTURE_DEF);
body.setUserData("platform2");
physicsWorld.registerPhysicsConnector(new PhysicsConnector(levelObject, body, true, false));
}
else if (type.equals(TAG_ENTITY_ATTRIBUTE_TYPE_VALUE_PLAYER))
{
player = new Player(x, y, vbom, camera, physicsWorld)
{
@Override
public void onDie()
{
scoreText.detachSelf();
BackButton.detachSelf();
}
};
levelObject = player;
}
else if (type.equals(TAG_ENTITY_ATTRIBUTE_TYPE_VALUE_ZOMBIE))
{
zombie = new Zombie(x, y, vbom, camera, physicsWorld);
levelObject = zombie;
}
else
{
throw new IllegalArgumentException();
}
levelObject.setCullingEnabled(true);
return levelObject;
}
});
levelLoader.loadLevelFromAsset(activity.getAssets(), "level/1.lvl");
}
这是当前的一个（＆＃39;除了Contactlistener之外完全有效！＆＃39;）： 代码：
private void createLevel(){
loadLevel("player",0,200);
loadLevel("platform1",0,40 );
loadLevel("platform1",350,40);
loadLevel("platform1",700,40);
loadLevel("platform2",1050,40);
loadLevel("platform2",1400,40);
loadLevel("platform1",1750,40);
//loadLevel("zombie",700,200);
}
private void loadLevel( final String tipus, final int number,final int numer){
camera.setBounds(0, 480, 250000, 40);
camera.setBoundsEnabled(true);
final FixtureDef FIXTURE_DEF = PhysicsFactory.createFixtureDef(0, 0.01f, 0.5f);
final int y = 0 + numer;
final int x = 0 +number;
final String type = tipus;
final Sprite levelObject;
if (type.equals("platform1"))
{
levelObject = new Sprite(x, y, resourcesManager.platform1_region, vbom);
PhysicsFactory.createBoxBody(physicsWorld, levelObject, BodyType.StaticBody, FIXTURE_DEF).setUserData("platform1");
}
else if (type.equals("platform2"))
{
levelObject = new Sprite(x, y, resourcesManager.platform2_region, vbom);
final Body body = PhysicsFactory.createBoxBody(physicsWorld, levelObject, BodyType.StaticBody, FIXTURE_DEF);
body.setUserData("platform2");
physicsWorld.registerPhysicsConnector(new PhysicsConnector(levelObject, body, true, false));
}
else if (type.equals("player"))
{
player = new Player(x, y, vbom, camera, physicsWorld)
{
@Override
public void onDie()
{
scoreText.detachSelf();
BackButton.detachSelf();
}
};
levelObject = player;
}
else if (type.equals("zombie"))
{
zombie = new Zombie(x, y, vbom, camera, physicsWorld);
levelObject = zombie;
}
else
{
throw new IllegalArgumentException();
}
levelObject.setCullingEnabled(true);
attachChild(levelObject);
}
顺便说一句，这就是我创建物理世界的方式：
private void createPhysics()
{
physicsWorld = new PhysicsWorld(new Vector2(0, -25.5f), true);
physicsWorld.setContactListener(contactListener());
registerUpdateHandler(physicsWorld);
engine.registerUpdateHandler(new FPSLogger());
}
private ContactListener contactListener()
{
ContactListener contactListener = new ContactListener()
{
public void beginContact(Contact contact)
{
final Fixture x1 = contact.getFixtureA();
final Fixture x2 = contact.getFixtureB();
if (x1.getBody().getUserData() != null && x2.getBody().getUserData() != null)
{
if (x2.getBody().getUserData().equals("player"))
{
player.increaseFootContacts();
if(firstTouch){
player.Run();
}
}
if (x1.getBody().getUserData().equals("platform2") && x2.getBody().getUserData().equals("player"))
{
engine.registerUpdateHandler(new TimerHandler(0.1f, new ITimerCallback()
{
public void onTimePassed(final TimerHandler pTimerHandler)
{
pTimerHandler.reset();
engine.unregisterUpdateHandler(pTimerHandler);
x1.getBody().setType(BodyType.DynamicBody);
}
}));
}
}
}
public void endContact(Contact contact)
{
final Fixture x1 = contact.getFixtureA();
final Fixture x2 = contact.getFixtureB();
if (x1.getBody().getUserData() != null && x2.getBody().getUserData() != null)
{
if (x2.getBody().getUserData().equals("player"))
{
player.decreaseFootContacts();
}
}
}
public void preSolve(Contact contact, Manifold oldManifold)
{
}
public void postSolve(Contact contact, ContactImpulse impulse)
{
}
};
return contactListener;
}
