Sitecore和SolrCloud启动重建(Sitecore and SolrCloud switch on rebuild)

 您的问题缺少很多信息。 但似乎你使用的是boxd2，因为如果你正在使用自定义代码处理冲突，你可以轻松解决问题。 
 
 如果您使用的是boxd2，则可以将陷阱体作为传感器。 
 
body.getFixtureList().get(0).setSensor(true); //assuming it has only one fixture
 
 并将其UserData设置为可以在发生冲突时检查的内容。 
 
body.getFixtureList().get(0).setUserData("trap");
 
 然后，定义一个联系人侦听器以检查与具有该用户数据的主体的冲突： 
 
//define the Contact listener
public class MyContactListener implements ContactListener{

    @Override
    public void beginContact(Contact contact){
        if ((String)contact.getFixtureA().getUserData()=="trap" || (String)contact.getFixtureB().getUserData()=="trap")
            //hurt player
    }

    @Override public void endContact(Contact contact){}
    @Override public void preSolve(Contact contact, Manifold oldManifold){}
    @Override public void postSolve(Contact contact, ContactImpulse impulse){}
};
 
 并在您的ini代码中创建和设置联系人侦听器。 
 
MyContactListener contactListener = new MyContactListener();
world.setContactListener(contactListener);

A lot of information is lacking on your question. But it seems you are using boxd2, because if you were handling the collisions with your custom code you would easily solve your problem.
 
If you are using boxd2, you can make your trap body a sensor.
 
body.getFixtureList().get(0).setSensor(true); //assuming it has only one fixture
 
And set its UserData to something you can check when the collision occurs.
 
body.getFixtureList().get(0).setUserData("trap");
 
then, define a contact listener to check for collisions with bodies with that user data:
 
//define the Contact listener
public class MyContactListener implements ContactListener{

    @Override
    public void beginContact(Contact contact){
        if ((String)contact.getFixtureA().getUserData()=="trap" || (String)contact.getFixtureB().getUserData()=="trap")
            //hurt player
    }

    @Override public void endContact(Contact contact){}
    @Override public void preSolve(Contact contact, Manifold oldManifold){}
    @Override public void postSolve(Contact contact, ContactImpulse impulse){}
};
 
And create and set the contact listener in your ini code.
 
MyContactListener contactListener = new MyContactListener();
world.setContactListener(contactListener);
