Bug #343
Cyberdemon infights
100%
Description
In the latest version of Doomsday, monsters are unale
to fight cyberdemons. This hasn't been tested with the
Spider Mastermind.
Doom2 Map08, the room with the Cybie and all the Hell
Barons is practically impossible because of this.
CyberDreams.wad Map07 IS impossible because of this.

I tested and it does in fact do the same for the Spider
Mastermind as well.

In Barrels of Fun the arachnatrons wouldn't fight with the
Mastermind either.

My fault, didn't know where comments appeared.

While trying to track this down I saw this in
jdoom/src/p_enemy.c (line 226):
dist =
P_ApproxDistance(actor->pos[VX] -
actor->target->pos[VX],
actor->pos[VX] -
actor->target->pos[VY]) - 64 * FRACUNIT
Surely that second "actor->pos[VX]" should be "actor->pos[VY]"?
Unfortunately changing this didn't fix the problem, so back
to digging I go...

OK, the real source of this bug is line 984 of
jdoom/src/p_inter.c:
((!target->threshold && !(source->flags2 & MF2_BOSS))||
target->type == MT_VILE) &&
The MF2_BOSS check was added in SVN 3128 along with other
changes meant to add some Heretic functionality to jDoom.
However, no equivalent check existed in the original Doom
source and having it here is preventing other monsters from
targetting bosses.

Well spotted. Yep, that is definetly a bug, I'll commit a
fix soon.

Good work. I'll look into and commit a fix for this logic
error soon.

Fixed in svn for 1.9.0-beta5.
In order to fix this properly I've had to implement a new MF3_NOINFIGHT flag. This flag can be used to prevent a mobj from being "in-fought with". And this means that all games' objects.ded's have been updated too.
