Take a look at this gif picture:
As you see the shadow acts as there is something else besides the sprite.
I think it’s because I set a circle ball with radius and the shadow only acts with the body’s shape.
this.texture = new Texture("sprites/water.png");
this.camera = new OrthographicCamera(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
this.camera.setToOrtho(false);
this.renderer = new SpriteBatch();
this.map = new TileMap(20, 20);
this.map.generateAllSame(new Texture("sprites/sprite.png"));
this.world = new World(new Vector2(), true);
this.createBodies();
RayHandler.setGammaCorrection(true);
RayHandler.useDiffuseLight(true);
this.ray = new RayHandler(this.world);
this.ray.setAmbientLight(0.2f, 0.2f, 0.2f, 0.1f);
this.ray.setCulling(true);
this.ray.pointAtLight(50, 0);
this.ray.setBlurNum(1);
camera.update(true);
this.spriteLight = new PointLight(ray, 128);
this.spriteLight.setDistance(500f);
this.spriteLight.setPosition(150, 150);
this.spriteLight.setColor(new Color(0.5f, 0.8f, 0.7f, 1f));
this.spriteLight.setSoftnessLength(0);
this.spriteLight.setSoft(true);
public void createBodies() {
CircleShape chain = new CircleShape();
chain.setRadius(10);
FixtureDef def = new FixtureDef();
def.restitution = 0.8f;
def.friction = 0.01f;
def.shape = chain;
def.density = 1f;
BodyDef body = new BodyDef();
body.type = BodyType.DynamicBody;
for (int i = 0; i < 3; i++) {
body.position.x = 40 + MathUtils.random(500);
body.position.y = 40 + MathUtils.random(500);
Body box = this.world.createBody(body);
box.createFixture(def);
this.bodies.add(box);
}
chain.dispose();
}
My render:
public void render() {
handleInput();
camera.update();
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
renderer.setProjectionMatrix(camera.combined);
renderer.disableBlending();
renderer.begin();
this.map.render(renderer);
renderer.draw(texture, 50, 50);
renderer.enableBlending();
for (Body body : this.bodies) {
Vector2 pos = body.getPosition();
renderer.draw(texture, pos.x + amount, pos.y);
}
renderer.end();
ray.setCombinedMatrix(camera.combined, camera.position.x, camera.position.y,
camera.viewportWidth * camera.zoom, camera.viewportHeight * camera.zoom);
ray.update();
ray.render();
}
And then I set a square polygon instead of a circle:
PolygonShape chain = new PolygonShape();
Vector2[] v = new Vector2[4];
v[0] = new Vector2(10f, 0f);
v[1] = new Vector2(45f, 0f);
v[2] = new Vector2(10f, 0f);
v[3] = new Vector2(0f, 45f);
chain.set(v);
This is a lot better, but as you can see, the shadow goes OVER the sprite itself, and it makes it look unrealistic. Looks like it’s missing some offsets for bodies.
What did I do wrong? I just started LibGDX in general.
