The top-right corner sets our position to use the maximum X value from our ActorBB

variable and subtract the actual width of the box, while the Y value is simply set to

the minimum size of the actor's bounding box Y variable.

We draw our rectangle next. The first parameter is the X value and determines

how thick or wide the bar appears on the sides. The second parameter, the Y

variable, does the same for the top and bottom bar. The ActualWidth variable

defines a very thin line, while a number such as 10 in the Y parameter creates a

nice thick one to stand out.

7. Let's take a look at where we actually get our bounding box information from. This
   may look like quite a bit, but it's really just a lot of the same information repeated
   over and over. We'll create our GetBB() function, which grabs our bounding box
   dimensions from our actor.
   /*****
   
   
   • Grabs bounding box around an actor
     *****/
     function Box GetBB(Actor Actor)
     {
     local Box CompBBox, OutBox;
     local Vector BoundingBoxCoords[8];
     local int i;
