java - Not able to change color with Slick2d Graphics context -

i'm playing around slick2d , can't change color of graphics context.

this have:

public void render(gamecontainer gc, graphics g) throws slickexception {     color color = new color(1f, 0f, 0f, 1f);     g.setlinewidth(2);     g.setcolor(color);     g.drawrect(100, 100, 100, 100); } 

i still rectangle white border.

i tried setcolor(color.red), nothing.

what missing?

edit 1: changing background red works: g.setbackground(new color(1f, 0f, 0f, 1f)); http://abload.de/img/bildschirmfoto2013-05b2uba.png the…

edit 2: g.getcolor(); giving me correct "red" color…

solved:

ok found error, dont understand it. set renderer vertex_array_renderer. after commenting out line able change color.

@override public void init(gamecontainer gc) throws slickexception {     //renderer.setrenderer(renderer.vertex_array_renderer); }  

try adding:

render(gamecontainer gc, graphics g) throws slickexception  {    graphics2d g = (graphics2d) bufferstrategy.getdrawgraphics();      //your code      render(g);     g.dispose(); } 

to code.
