Hi. I like to learn programming by examples but I need help 
learning how to read documentation. I have some idea of how it 
works in some aspects but in others i get completely stuck 
because there are no examples or code snippets.

I am using dgame (dgame-dev.de) and im reading the documentation 
for changing the background text of my font in my program.
I have the basic code for font creation but i need to make 
changes to the colors.

import std.stdio;
import std.system;

import Dgame.System;
import Dgame.Window;
import Dgame.Graphic;
import Dgame.Audio;
import Dgame.Math;

void main()
{
      Font dejavu = Font("resources/dejavu.ttf", 12);
      Text CurrentFps = new Text(dejavu);

      ..window loop
}

The documentation here 
(http://dgame-dev.de/index.php?controller=learn&mode=package&package=graphic&module=Text&version=0.6)...
gives me the Text() class but i dont know how to use "foreground, 
background, and Font mode" or at least turn it into usable syntax.

Those describe simple class members, so you can set them through assignment: Text CurrentFps = new Text(dejavu); // change to white on black CurrentFps.foreground = Color4b.White; CurrentFps.background = Color4b.Black; // change mode CurrentFps.mode = Font.Mode.Shaded; I haven't actually used this library, but since the doc describes it with variable syntax (`Color4b foreground;`) that means you should be able to just assign to them like ordinary object member variables.

Wow, thank you so much. I have never seen code like that before but the documentation there made me scratch my head. Thank you.
