Enable and fix minibosses

Please note that this tutorial is a work-in-progress. If you find any errors, please edit the talk page for this article.

This tutorial is for how to enable the actors BOSS1, BOSS2, BOSS3, and BOSS4 become their miniboss counterparts without any bugs so you can put them in user maps and\or CON hacks.

Intoduction

From now on I will refer to the bosses as follows:

• BOSS1 - Ep. 1 - Battlelord
• BOSS2 - Ep. 3 - Cycloid Emperor
• BOSS3 - Ep. 2 - Overlord (Yes, these two are mixed up. Do not try to switch them to what they should be.)
• BOSS4 - Ep. 4 - Alien Queen

The Battlelord is programmed sufficently enough to allow its placement in maps, and the official levels do contain some mini Battlelords. In order to successfully perform the actions described in this tutorial, you will need to understand that while the Battlelord, Overlord, and Cycloid Emperor are already enabled and just require an easy bug fix or two, the Alien Queen will require some CON coding skill, time, patience, and effort for reasons described below.

When I say "Change it to this:", I want you to copy the text below it in the box and overwrite the text in the box above by pasting it when the old text is completely selected, but in your .CON files of course. There is not much point in changing the web page!

Also, when I say "Open <insert name of .CON file here>.", I want you to open whatever .CON file the text in the box below is in. I am just stating the defaults.

Strengths and Gamevars

Open USER.CON. Scroll down to here:

define BOSS1STRENGTH            4500
define BOSS1PALSTRENGTH         1000
define BOSS2STRENGTH            4500
define BOSS3STRENGTH            4500
define BOSS4STRENGTH            6000

Change it to this:

define BOSS1STRENGTH            4500
define BOSS1PALSTRENGTH         1000
define BOSS2STRENGTH            4500
define BOSS2PALSTRENGTH         1000
define BOSS3STRENGTH            4500
define BOSS3PALSTRENGTH         1000
define BOSS4STRENGTH            6000
define BOSS4PALSTRENGTH         1333

gamevar BOSSX 0 2
gamevar BOSSY 0 2
gamevar BOSSZ 0 2
gamevar BOSSSPRPAL 0 2
gamevar BOSSLOTAG 0 2
gamevar BOSSSECTOR 0 2

The strengths from mini BOSS2 and BOSS3 was put the same as BOSS1, oblivious because the big versions are the same. BOSS4 is proportional as 4500 - 1000 to 6000 - 1333. The gamevars need to remain the exact same thing as what is shown here.

Note that the strengths do not have to be what is described here. All that matters is that these eight defines exist.

BOSS4

BOSS4 is a bit more complicated because there is no programming at all for it to be a miniboss.

Animations, Movements, and Artificial Intelligence

First, go to where it says:

action ABOSS4WALK          0 4  5  1  30
action ABOSS4DYING        40 9  1  1  20

ai AIBOSS4SHOOT ABOSS4ABOUTTOSHOOT BOSS4STOPPED faceplayer
ai AIBOSS4DYING ABOSS4DYING BOSS4STOPPED faceplayer

Change it to this:

action ABOSS4DYING        40 9  1  1  20

 else ifcount SHRUNKCOUNT { sizeto 40 40 }
 else { state genericshrunkcode }
ends

Note that "state boss4palshrunkstate" is supposed to be there. You should put it there because that is a very convenient space for it.

state checkboss4hitstate

Next, go to this:

state checkboss4hitstate
  ifrnd 2
    spawn BLOODPOOL

      break

    ifrnd 16
    {
      action BOSS4FLINTCH
      move 0
    }
  
  }
ends

Change it to this:

         break
       }
     }

    globalsound DUKE_TALKTOBOSSFALL // Note that since the Alien Queen is female, this line is incorrect. She *is* a bitch.

   addkills 1
    ai AIBOSS4DYING

    sound BOS4_DYING
  }
  else
  {
    soundonce BOS4_PAIN
    debris SCRAP1 1

    ifaction ABOSS4LAYIT
      break

    ifrnd 16
   {
      action BOSS4FLINTCH
      move 0
    }
  }
ends

state boss4code

After that, go to:

Conclusion

After that, you should be all set!

To insert a miniboss in a user map, create the boss sprite you want, and then give it a palette of something other than 0. I recommend pal 3 because pal 21 makes some minor changes to the first three boss' sprites, while the Alien Queen looks red with pal 21. In the end, all that matters is that the spritepal is not 0.
