Title: Enemies using weapons
Post by: fedorajoe on October 23, 2016, 06:52:53 PM

When you fight a player character as an enemy... what determines the weapon the enemy is equipped with?

Just playing around, I tested enemy Kain and Enemy Yang, and if told to use the Fight command, they have weapons equipped.  But I can't see how to change the values, and it doesn't seem to relate to what the actual characters/actors have equipped.

Anybody know?

Thanks!

Indeed, this was an old mystery that I put to bed some time ago. It is set to be the Deathbringer. I posit that this is part of a removed sequence where the Dark Knight copy would attack Paladin Cecil normally at one point or another...

Here is the information on that, but here is the pertinent part of that...


02/D028   AD 4E ED   LDA $ED4E  [$7E:ED4E]   A:0080   X:0000   Y:0012   P:eNvMxdizc - Load Monster... something (Yousei's RAM notes say that ED50 is palette data so it may deal something with size or graphic or something)
$02/D02B   29 10   AND #$10   A:001F   X:0000   Y:0012   P:envMxdizc - Get rid of all but 10.
$02/D02D   F0 1B   BEQ $1B    [$D04A]   A:0010   X:0000   Y:0012   P:envMxdizc - All normal monsters branch here where Battle Characters continue on.
----------------------------------------------------------------------------------------------------------------
$02/D02F           A9 18   LDA #$18   A:0010   X:0000   Y:0012   P:envMxdizc - Load Deathbringer into A.
$02/D031   20 BA D8   JSR $D8BA  [$02:D8BA]   A:0018   X:0000   Y:0012   P:envMxdizc - Jump to Subroutine

The weapon number (yes, singular they never planned on any other weapon being available to Enemy PC's) follows the normal listings.

Given that it's a two-byte load command preceded by a branch and followed by a subroutine jump, it'd be tricky to rewire in order to get a character-dependent routine in there... but nothing's impossible.
It will most likely be something I implement for my own purposes eventually, so I'Lloyd remember to post here when I do.
