TutorialHUD(H).DrawDebugText(index_array$":

"@command.CommandName,vect2d(0,YPos),

H.Canvas.Font,cmnd_color);

// Draws next line beneath current one

YPos += YL;

}

}

}

}

We start by setting our font to be drawn in the top-left corner, as indicated by the

coordinates 0,0. From there we use an if-else statement to make our currently

highlighted text stand out by coloring it red and all other text white. We also draw a

transparent gray rectangle across the entire screen.

How do we get one line to display beneath the other? Well the line YPos += YL;

represents the Y position for our text, and we set it to be its current position plus

the float YL.

We're also calling our HUD class and telling it to draw the DrawDebugText()

function, which we'll cover shortly.

7. The final thing we need to do in this class is set the default properties of
   our variables:
   DefaultProperties
   {
   bShowDebugMenu=false
   CurrentPage=-1 // Starts us on the first page
   CurrentIndex=0

/** Look in UDKInput.Ini to find additional debug

commands to add to this list */
