Render 2D lines on screen

[NathanPB]

Hello Everyone, I want to drawn a square around my hud (like this)

but i fucking cant because Gui#drawVerticalLine / horizontalLine arent working as expected
 

    public void render(){
        if(renderborders){
            Integer color = Integer.parseInt("FF0000", 16);
            drawHorizontalLine(getX(), getX()+width, getY(), color);
            drawHorizontalLine(getX(), getX()+width, getY()+height, color);

            drawVerticalLine(getY(), getY()+height, getX(), color);
            drawVerticalLine(getY(), getY()+height, getX()+width, color);
        }
    }

The render method are being invoked, I tested it using Intellij Idea debugger (or System.out.println)
What am I doing wrong? thanks everyone

EDIT: to explain some more the "drawVerticalLine(xPos,minY,maxY,color)"

And the "drawHorizontalLine(minX,maxX,yPos,color)"

[sir_titi]

hmmm, this is really weird :s. I'm afraid i might not be able to help you here, dammit.

[sir_titi]

Is data synced to server? because i have noticed you set the position but on server from Client :s. This can not work.

Oh sorry my bad not correct:p.

[NathanPB]

I understood your question. Im synchronizing the data using packets, its all ok

[sir_titi]

Hah yea, my bad :p.

Nevertheless your issue is weird man :s, cuss your "text" is rendered properly, but the "drawing" doesn't.
