LibGDX scissors does not work

Question

I want to clip a certain part of the screen, thus everything which lays outside is not drawn. My code looks like this:

public void draw(Camera camera, ShapeRenderer renderer){
        Rectangle scissors = new Rectangle();
        Rectangle clipBounds = new Rectangle(pos.x, pos.y, pos.x+width, pos.y+height);
        ScissorStack.calculateScissors(camera, 0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), new Matrix4(), clipBounds, scissors);
        renderer.begin(ShapeType.Filled);
        ScissorStack.pushScissors(scissors);
        for(Block[] row : blocks){
            for(Block block : row)
                block.draw(renderer);// draw some rects
        }
        ScissorStack.popScissors();

        renderer.end();
    }

But this code has no effect, i.e. shapes that lay outside clipBounds are drawn, too. What's wrong with my code?

Answer 1

The rendering doesn't happen until renderer.end() so put that inside your ScissorStack.
