If you guys are interested in some numbers, out of curiosity I made a sky
with 1 pixel wide vertical stripes evenly spaced 16 pixels apart and then
measured the distance in doom on my 14" screen. In 64ths of an inch the
distances between stripes was:
57,49,41,39,34,32,30,30,30,30,31,33,36,41,46,52
This verifies Greg's statement, the stripes at the edges of the screen are
almost exactly twice as wide as those in the middle. The numbers are a bit
odd because of screen distortions, I think. Kinda like the sky was mapped
onto a dome...

I had this same problem once after using and removing the Barney Doom patch
and then upgrading to Doom 1.2; I had to reinstall. The problem is that WAD
replacement may not recreate the originial WAD exactly as it was, and patches
look for specific pieces of that file. I'm leery of replacing graphics now,
just for that reason.
Unless you have a backup WAD, better reinstall.

Heya,
Don't replace the f_sky texture, it is just a method of plotting the sky
and shows the sky texture for that episode or level. You want to replace
teh sky1, 2, or 3 graphics.
Hop i Helped.

Don't anybody execute my character if this is stupid, but if a rocket could
essentially fire another rocket, couldn't a new monster be made that shoots
floating droids that home in on the player and shoot some other kind of
projectile? I think this would be interesting if it could be done. I
haven't gotten very deep into dehacked, so I don't know for sure.

Give lost souls a projectile weapon. The Pain Elemental would then be your
monster. I don't know if this is actually possible, however.

If you turn on the spot, watch how the sky and walls line up column for
column.

Subject: Sky warping solved
I told you all already- it's really simple:
Someone mentioned that walls are left warped- they're not. But the spherical
aberration correction that "unwarps" them is not done on the sky texture- I
don't think it's done on any ceiling/floor textures (check out a "tiled"
ceiling closeup across a large room and see for yourself).
Please, no more useless banter. I'm not the only one to have come up with the
same answer. :D

That's essentially how projectiles fire other projectiles- they fire a
"ghost" of the monster that fired them, which in turn fire other "ghosts".
With the new code pointer editing in DHE 3.0, it should be possible to do
this a bit more gracefully.
As to your suggestion, yes- that's entirely possible. Either use the pain
elemental attack frame (711) or its code pointer to shoot out lost souls,
then edit the lost souls so that they act the way you want. It would be
something like:
Patch for Doom I only (replaces a Doom II frame)
1. Copy imp (thing 12) data to lost souls (thing 19).
2. Change original imp's far attack frame to 711.
3. Change the sprite # on frame 711, change its duration to 0, and it's next
frame to 452 (the original imp attack frame).
Now, whenever an imp attacks from far away, it will spawn out another imp and
a fireball. When those spawned imps attack, they should behave like regular
imps.
To do this patch (usable in Doom II) in the upcoming release of DHE 3.0:
Alter lost soul's stats and sprites to taste.
Frame 454 (imp attack):
Code pointer: Frame 711
Frame 590 (lost soul charge):
Code pointer: Frame 454
Much simpler, no? This makes imps shoot lost souls, lost souls shoot
fireballs. Both will not fire, but scratch, if you are close by (a
side-effect of most projectile-firing monsters).

I tried making a wad with different player starts for different skills. All I did was
create clones. So the only way for an editor to check for player starts and deathmatch
starts is to check the "type" and not the skill levels.

Interesting, so the player is always centered with the sky mapped on a
cylinder (not a sphere) 'out there' - and this's what gives the illusion of
distance. I guess Quake will map the sky onto a sphere.

Actually this should be expected, being that DOOM is column oriented. Nowhere
is a line or plane in the Z axis where X and Y are not constant: a cylinder
is natural. Whereas a sphere requires calculations the engine is not
designed to perform.
