You will need 4 spewers.

One spewer launches 3 other spewers sequentially.

Then each of the 3 spewers would have thier min/max set to one direction.

i.e. to fire a nuke north:

min = 0, 0, 20
max = 0, 0, 20

to fire a nuke east:

min = 20, 0, 0
max = 20, 0, 0

to fire a nuke west:

min = -20, 0, 0
max = -20, 0, 0

The 'Das Tornado' does something similar.

To fire it at a 120 deg angle from north (velocity 0, 0, 20) , you would need to do some trig to figure out the correct X and Z velocities. Then you'd set the max and min of a spewer to the same values. Then reverse the sign of the X value to get the X,Z velocities of the other spewer and set its min and max.

Here's the low down of the x&z values (V is your velocity vector). TM won't do the computations obviously

spewerNorth.ent:
min = 0, V, V
max = 0, V, V

spewerSouthwest.ent:
min = (V * sin 240), V, (V * cos 240)
max = (V * sin 240), V, (V * cos 240)

spewerSoutheast.ent:
min = (V * sin 120), V, (V * cos 120)
max = (V * sin 120), V, (V * cos 120)

mainSpewer.ent:
SpewType0 = spewer/spewerNorth
SpewType1 = spewer/spewerSouthwest
SpewType2 = spewer/spewerSoutheast
CycleType = 0
MaxSpewCount = 3

I set the Y velocity to V as well so it fires upwards at a 45 degree angle. To steepen the angle, give it a higher Y velocity. To flatten it lower the Y velocity. If you want a specific angle, then things get a little more complicated:

X = V * cos azmuth * sin compass-heading
Y = V * sin azmuth
Z = V * cos azmuth * cos compass-heading

the compass-heading is the X/Z direction:
North = 0 degrees
East = 90 degrees
South = 180 degrees
West = 270 degrees

The azmuth is the Y direction:
Parallel to ground (horizon) = 0 degrees
perpendicular to ground (zenith) = 90 degrees

spewerNorth.ent:
min = 0, 70, 70
max = 0, 70, 70

spewerSouthwest.ent:
min = -60, 70, -35
max = -60, 70, -35

spewerSoutheast.ent:
min = 60, 70, -35
max = 60, 70, -35

But.

On the weapon in question, I want everyone on the map to see the explosion and various effects (it's a large effect). The way to accomplish that seems to be the transitory = 0 setting. But, it seems that using that setting causes anyone who logs on to the server to see the explosion as soon as they log on, even though it may have exploded many minutes earlier. I'd prefer that to not be the case. Any ideas why that happens? Could adding a lifespan = X setting or something else in the explo ent eliminate that problem?

Just so you know (I had this done before you gave your recommended way of doing it), it goes like this:
weapon -> projectile -> explo (chains to the 3 spewers) -> (the aforementioned) spewers -> (three) projectiles -> explo
In order for everyone to see everything from anypoint on the map, it seems necessary to have transitory = 0 for just about everything. Though it may not be necessary for the final explo ent, I'm not sure. I hope that made sense.

But setting it to 0 will cause it to be included in the 'playback' on the client, so long as the player is close enough to see them.

Apparently so. When I play on my TeamCTF server, I see every weapon that was fired near the first standard checkpoint on the map (which is where the camera sits before your first spawn) since the beginning of the game. Or at least thats what it looks like. That would also explain why people have difficulty connecting to a TeamCTF server when there are people already on.
