[Unknown] Hexen, Inconsistencies.

[Kristus]

If this has already been mentioned my bad. But I noticed a few Hexen inconsistencies.

There are only a few minor so far but here goes.

1. Gas clouds from Mushrooms in Hexen are not pushable by the chaos device. They are in Zdoom.

2. In Hexen, a Mage with the boots of speed can run faster than his frost shards and freeze himself on them. This can't be done with Zdoom, as the shards don't collide on the Mage.

2) is actually a bug fix. This happened because the shards were not given the proper owner in Hexen - but in ZDoom they actually are. I remember that Randy added quite a bit of code to the missile spawning function to fix this.

1) confuses me a bit as the cloud has the 'CANBLAST' flag set explicitly. But I can't see anything analogous in Hexen. I wonder why it had that flag.

[Gez]

I wonder why it had that flag.

Because for some reason, a poison cloud spawned by a cleric's flechette can be blasted, while one spawned from a mushroom cannot.


As I posted in the what the hell thread, I don't know why there is a discrepancy given the spawning code is the same.

[Graf Zahl]

Ah. That's it. I assume that the crucial factor then is the fact that one's owned by a player and the other by a scenery object. I guess I'll have to redo the fix then.

[Graf Zahl]

Ok, 'fix' reverted. I won't do anything else unless I know what's happening here.

[Gez]

I continue to be puzzled:

Code: Select all

// Blast all mobj things away
void P_BlastRadius(player_t *player)
{
	mobj_t *mo;
	mobj_t *pmo=player->mo;
	thinker_t *think;
	fixed_t dist;

	S_StartSound(pmo, SFX_ARTIFACT_BLAST);
	P_NoiseAlert(player->mo, player->mo);

	for(think = thinkercap.next; think != &thinkercap; think = think->next)
	{
		if(think->function != P_MobjThinker)
		{ // Not a mobj thinker
			continue;
		}
		mo = (mobj_t *)think;
		if((mo == pmo) || (mo->flags2&MF2_BOSS))
		{ // Not a valid monster
			continue;
		}
		if ((mo->type == MT_POISONCLOUD) ||		// poison cloud
			(mo->type == MT_HOLY_FX) ||			// holy fx
			(mo->flags&MF_ICECORPSE))			// frozen corpse
		{
			// Let these special cases go
		}
		else if ((mo->flags&MF_COUNTKILL) &&
			(mo->health <= 0))
		{
			continue;
		}
		else if (!(mo->flags&MF_COUNTKILL) &&
			!(mo->player) &&
			!(mo->flags&MF_MISSILE))
		{	// Must be monster, player, or missile
			continue;
		}
		if (mo->flags2&MF2_DORMANT)
		{
			continue;		// no dormant creatures
		}
		if ((mo->type == MT_WRAITHB) && (mo->flags2&MF2_DONTDRAW))
		{
			continue;		// no underground wraiths
		}
		if ((mo->type == MT_SPLASHBASE) ||
			(mo->type == MT_SPLASH))
		{
			continue;
		}
		if(mo->type == MT_SERPENT || mo->type == MT_SERPENTLEADER)
		{
			continue;
		}
		dist = P_AproxDistance(pmo->x - mo->x, pmo->y - mo->y);
		if(dist > BLAST_RADIUS_DIST)
		{ // Out of range
			continue;
		}
		P_BlastMobj(pmo, mo, BLAST_FULLSTRENGTH);
	}
}

There is code made specifically to let poison clouds be pushed.

[Graf Zahl]

I can't see either what makes the ones from the mushroom different. They should be blasted if that code worked as expected.

[Graf Zahl]

1 is fixed now.

2) is actually a bug fix. This happened because the shards were not given the proper owner in Hexen

How come I've never seen monsters being turned "insane" by the secondary frost shards? In vanilla Doom it nearly always happened that monsters shot by disappeared objects would start shooting at an inexistent target.

[RaVeN-05]

1. Heh, true, never noticed about this (interest). But blast sound and effect for "Gas clouds from Mushrooms" work. But Gas still on place where spawned. Looks like bug in vanilla hexen. For me pushing gas more fanny, but yes guys you right.

Because ZDoom cleans up after actors that disappear. Doom did not.
