Java Box2D（LibGDX）中未正确碰撞的实体

所以，在我的游戏中，我有一个带有多边形形状的box2D动态实体作为我的玩家，还有一个带有链状形状的box2D静态实体作为静态框。调试渲染器正确显示所有框。当玩家从顶部与盒子相撞时，盒子会相撞，但当玩家从两侧相撞时，盒子会向右移动。我曾尝试将多边形用于静态框，但它的行为很奇怪。我不知道怎么了

代码如下：

球员身体和固定装置定义：

        bdef=new BodyDef();
        bdef.position.set((WIDTH/2+169)/PPM,100/PPM);
        bdef.type=BodyType.DynamicBody;
        body=world.createBody(bdef);

        PolygonShape shape=new PolygonShape();
        shape.setAsBox(16/PPM,16/PPM);

        fdef=new FixtureDef();
        fdef.shape=shape;
        fdef.filter.categoryBits=B2DVars.BIT_PLAYER;
        fdef.filter.maskBits=B2DVars.BIT_BLOCK;
        body.createFixture(fdef).setUserData("player");

            bdef=new BodyDef();
            fdef=new FixtureDef();
            bdef.type=BodyType.StaticBody;
            bdef.position.set((col+0.5f)*tileSize/PPM,(row+0.5f)*tileSize/PPM);

            ChainShape chainShape=new ChainShape();
            Vector2[] v=new Vector2[5];
            v[0]=new Vector2(-tileSize/2/PPM,-tileSize/2/PPM);
            v[1]=new Vector2(tileSize/2/PPM,-tileSize/2/PPM);
            v[2]=new Vector2(tileSize/2/PPM,tileSize/2/PPM);
            v[3]=new Vector2(-tileSize/2/PPM,tileSize/2/PPM);
            v[4]=new Vector2(-tileSize/2/PPM,-tileSize/2/PPM);
            chainShape.createChain(v);

            fdef.friction=0;
            fdef.shape=chainShape;
            fdef.isSensor=false;
            fdef.filter.categoryBits=B2DVars.BIT_BLOCK;
            fdef.filter.maskBits=B2DVars.BIT_PLAYER;
            world.createBody(bdef).createFixture(fdef).setUserData("block");

静态箱体和夹具定义：

        bdef=new BodyDef();
        bdef.position.set((WIDTH/2+169)/PPM,100/PPM);
        bdef.type=BodyType.DynamicBody;
        body=world.createBody(bdef);

        PolygonShape shape=new PolygonShape();
        shape.setAsBox(16/PPM,16/PPM);

        fdef=new FixtureDef();
        fdef.shape=shape;
        fdef.filter.categoryBits=B2DVars.BIT_PLAYER;
        fdef.filter.maskBits=B2DVars.BIT_BLOCK;
        body.createFixture(fdef).setUserData("player");

            bdef=new BodyDef();
            fdef=new FixtureDef();
            bdef.type=BodyType.StaticBody;
            bdef.position.set((col+0.5f)*tileSize/PPM,(row+0.5f)*tileSize/PPM);

            ChainShape chainShape=new ChainShape();
            Vector2[] v=new Vector2[5];
            v[0]=new Vector2(-tileSize/2/PPM,-tileSize/2/PPM);
            v[1]=new Vector2(tileSize/2/PPM,-tileSize/2/PPM);
            v[2]=new Vector2(tileSize/2/PPM,tileSize/2/PPM);
            v[3]=new Vector2(-tileSize/2/PPM,tileSize/2/PPM);
            v[4]=new Vector2(-tileSize/2/PPM,-tileSize/2/PPM);
            chainShape.createChain(v);

            fdef.friction=0;
            fdef.shape=chainShape;
            fdef.isSensor=false;
            fdef.filter.categoryBits=B2DVars.BIT_BLOCK;
            fdef.filter.maskBits=B2DVars.BIT_PLAYER;
            world.createBody(bdef).createFixture(fdef).setUserData("block");

编辑：问题不再是，这是我通过变换设置播放器位置的问题，但现在我不知道，当我按下按钮时，如何使播放器移动，当我松开按钮时如何停止？

移动

动态主体

不应通过

设置变换

来完成。设置

DynamicBody

位置最平滑的方法是通过

MouseJoint

，但它是否能帮助您取决于您所追求的运动类型。这是一个很好的起点

以这种方式使用contact listener检查冲突

'if((contact.getFixtureA().getBody() == bodyEdgeScreen &&
                        contact.getFixtureB().getBody() == body2)
                        ||
                        (contact.getFixtureA().getBody() == body2 &&
                                contact.getFixtureB().getBody() == bodyEdgeScreen))'

你能添加处理碰撞的代码吗？它是Box2D。库中的冲突不是已经完成了吗？您可以将

ContactListener

添加到您处理冲突的box2d世界中（如wiki中所述：）。从你的评论中，我了解到你没有这样做。
