I have this line: Gdx.gl10.glLineWidth(width); Now, I do intend to draw a pretty thick line, and, unfortunately when I type in small values like 1 or 5 the line is obviously
From libgdx 1.0 on there is also the ShapeRenderer's rectLine method available. See a simple example.
ShapeRenderer shapeRenderer = new ShapeRenderer();
shapeRenderer.begin(ShapeType.Filled);
shapeRenderer.rectLine(x1, y1, x2, y2, width);
shapeRenderer.end();
That seems to be the easiest way to draw thick lines now.
