libgdx Shaperenderer line .. How to draw line with a specific width

问题

I am trying to draw a line of specific width using libgdx shape renderer. I followed this link

The problem is if i specify more line width i.e more than 9 it does not show increased width. More than 9 either i specify 20 or 100 pixels it will have the same result as 9

shapeRenderer.begin(ShapeType.Line);
    shapeRenderer.line(50, 70, 0, 50, 200, 0, Color.BLUE, Color.RED);
    int lineWidth = 20; // pixels
    Gdx.gl10.glLineWidth(lineWidth / camera.zoom);
     shapeRenderer.end();

Thanks Shakeel

回答1:

To query the range of supported widths and the size difference between supported widths within the range, call glGet with arguments GL_ALIASED_LINE_WIDTH_RANGE, GL_SMOOTH_LINE_WIDTH_RANGE, and GL_SMOOTH_LINE_WIDTH_GRANULARITY.

Reference

To avoid device specific behavior, I use a quad instead. Draw a 1x1 square from a small texture and then position, scale (depending on the width and height of the line you wanted to draw), color, and rotate it.

You should use ShapaRenderer.rectLine. You can see a more detailed answer here

Use this

shapeRenderer.begin(ShapeRenderer.ShapeType.Filled);
instead of shapeRenderer.begin(ShapeType.Line);
