/** Holds the image to use for the crosshair */

var Texture2D CrosshairImage;

/** Various colors */

var const color BlackColor;

/** color to use when drawing the crosshair */

var config color CrosshairColor;

We're going to use much of the same code that Epic uses for drawing the crosshair.

Rather than go through the convoluted processes of drawing the crosshair through

PostRender() and doing a number of checks, we're just going to draw the crosshair

at all times.

2. We'll call our function, DrawWeaponCrosshair();, and begin by defining the
   local variables.
   /**
   
   
   • Draws the crosshair
     **/
     simulated function DrawWeaponCrosshair()
     {
     local vector2d CrosshairSize;
     local float x,y,ScreenX, ScreenY;
     local MyWeapon W;
     local float TargetDist;
   
   
   
   

/** Set weapon and target distance */

W = MyWeapon(PawnOwner.Weapon);

TargetDist = W.GetTargetDistance();

/** Sets crosshair size */

CrosshairSize.Y = ConfiguredCrosshairScaling *

CrossHairCoordinates.VL * Canvas.ClipY/720;

CrosshairSize.X = CrosshairSize.Y *

( CrossHairCoordinates.UL / CrossHairCoordinates.VL );

/** Sets screen dimensions */

X = Canvas.ClipX * 0.5;

Y = Canvas.ClipY * 0.5;

ScreenX = X - (CrosshairSize.X * 0.5);

ScreenY = Y - (CrosshairSize.Y * 0.5);
