Step #1
// ------------------------------------------
// Weapons.cs
// ------------------------------------------

1a) Add this to the bottom of function WeaponImage::onMount (Note: These are only examples how to do
it using some of my weapons. you'll need to add an else if statement for each new weapon you add):

   if (%this.item $= "EMPMortar" || %this.item $= "PulseMortar") //Add any new weapons from here
      %obj.client.setWeaponsHudActive("Mortar");
   else if(%this.item $= "Flakgun")
      %obj.client.setWeaponsHudActive("Chaingun");               //to here. Set them to the weapon of reticle it uses.
   %obj.client.setWeaponsHudActive(%this.item);  //Add this at the end. It handles the highlighting of icons.


2a) Do the same to function WeaponImage::onUnmount. except add a 1 to the end like this:

   if (%this.item $= "EMPMortar" || %this.item $= "PulseMortar") //Add any new weapons from here
      %obj.client.setWeaponsHudActive("Mortar", 1);
   else if(%this.item $= "Flakgun")
      %obj.client.setWeaponsHudActive("Chaingun", 1);            //to here. Set them to the weapon of reticle it uses.
   %obj.client.setWeaponsHudActive(%this.item, 1);


Step #2
// ------------------------------------------
// serverCommandMap.cs
// ------------------------------------------
This does the same as when you mount weapons, except it handles when you come out of
the command map. Add this to the bottom of function serverCmdResetControlObject:

   if(isObject(%client.player))
   {
      %this = %client.player.getMountedImage($WeaponSlot);
      if (isObject(%this))
      {
         if (%this.item $= "EMPMortar" || %this.item $= "PulseMortar")   //Add any new weapons from here
            %client.setWeaponsHudActive("Mortar");
         else if(%this.item $= "Flakgun")
            %client.setWeaponsHudActive("Chaingun");                     //to here. Set them to the weapon of reticle it uses.
         %client.setWeaponsHudActive(%this.item);
      }
   }
