Box2Dlights 阴影不起作用

Question

我刚刚在我的 LibGDX 游戏中实现了 Box2DLights。它工作正常，但在我添加静态物体后，它们不会投射阴影。

然而，墙壁确实以某种方式增加了点光。

以下是我使用 Box2D 和 Box2Dlights 的代码部分：

Vector2 gravity = new Vector2(0,0);
debugRenderer = new Box2DDebugRenderer();
world = new World(gravity, false);

rayHandler = new RayHandler(world);
rayHandler.setCombinedMatrix(camera.combined);
rayHandler.setShadows(true);

// This adds wall tiles from TiledMap into obstacles and to box2d world         
for (MapObject wall : mapObjects) {                                             
    RectangleMapObject rmo = (RectangleMapObject) wall;                         

    if (rmo.getName() == null || !rmo.getName().contentEquals("window")) {      
        Rectangle rec = rmo.getRectangle();                                     


        obstacles.add(rec);                                                     
        rec.set(rec.x / 128 - mapRec.x, rec.y / 128 - mapRec.y,                 
                rec.width / 128, rec.height / 128);                             

        BodyDef bodyDef = new BodyDef();                                        
        bodyDef.type = BodyType.StaticBody;                                     
        bodyDef.position.set(rec.getX()+rec.width/2,rec.getY()+rec.height/2);  

        Body body = world.createBody(bodyDef);                                  

        PolygonShape groundBox = new PolygonShape();                            

        groundBox.setAsBox(rec.width/2,rec.height/2);                           

        body.createFixture(groundBox, 1.0f);                                    

        groundBox.dispose();                                                    
    }                                                                           
}                                       

//The point light and the cone light;                                                                                                                              
pointLight= new PointLight(rayHandler, 100, new Color(1,1,1,0.5f), 0.5f, myCharacter.getAdjustedPosX(), myCharacter.getAdjustedPosY());                            
coneLight = new ConeLight(rayHandler, 100, new Color(1,1,1,0.5f), 3, myCharacter.getAdjustedPosX(), myCharacter.getAdjustedPosY(), myCharacter.getRotation(), 30f);

还有渲染部分：

// After I have rendered walls sprites etc.                                                                                     
world.step(1/60f, 6, 2);                                                                                                        
rayHandler.setCombinedMatrix(camera.combined, camera.position.x, camera.position.y,camera.viewportWidth, camera.viewportHeight);
rayHandler.updateAndRender();                                                                                                   
debugRenderer.render(this.world, camera.combined);

我已经尝试了许多教程和示例中的东西，例如我添加了 world.step()，但它们并没有改变任何东西。

在我将柔软度长度设置为零后，阴影开始工作。

pointLight.setSoftnessLength(0);
coneLight.setSoftnessLength(0);
