Selecting a target

This is Jon Jorajuria's code, tried to contact him to ask but his e-mails are not updated. My question is how do I initialize an ai that will work with this? Such as -

%ai = new AIPlayer() {
datablock = "Default"; 
position = "149 150 151"; 
};

function serverCmdSelectNearestTarget(%client)
{
   %actor = %client.actor;
   %searchMasks = $TypeMasks::ShapeBaseObjectType;
   %radius = 150;
   %pos = %actor.getPosition();
   InitContainerRadiusSearch(%pos, %radius, %searchMasks);
  
   while ((%targetObject = containerSearchNext()) != 0) 
   {
      %id = %targetObject.getId();
      %name = %targetObject.getName();
      %class = %targetObject.getClassName();

      if(%id == %actor.getId())
         continue;
         
      if(%class !$= "Actor" && %class !$= "AIActor")
         continue;

      %ghostIndex = %client.GetGhostIndex(%targetObject);
      commandToClient(%client, 'SelectObj', %ghostIndex);
      return;
   }
   
   return;
}

Thanks.
