newageofpower I was digging around on the forum for the first mention of a spacer in a needlegun payload, and I found one on 31 Jan. Y'all posted the collab on 2 Feb... When was the original flect gun screenshot taken? Hmm. I'm fairly certain my co-author had the basic design by the 27th. I was hesistant on posting some of our concepts (so that I could crush opponents in a hypothetical multiplayer simulation), but Apophys wanted to publish, and I felt that this design concept - reducing effective sectional density by exploiting flaws in the game engine - was something that qswitched should fix asap. part of me wonders if the nanogram particle stream would actually have that effect or if it is a result of a quirk in the damage system. Small mistake, the Graphogel Flect masses 26.7 micrograms. Still... Probably not. At these velocities, everything behaves like a fluid. Despite being fired at 212km/s, the graphogel flect delivers a miniscule 600 Joules of energy. Yeah, it's extremely concentrated, but the flect's energy should rapidly disspate in shockwaves through the solid osmium block. Perhaps multiple impacts on the same spot would eventually compromise the armor, but that wasn't what happened.

That may explain the "bloom" shaped damage display.

I cannot build a flect gun, not that I didn't try, but that I got a CTD when I loaded the flect into a Gw Railgun. dropping the power down to 100kw didn't fix it nore did loading it into a new railgun

Now go back and add the spacer. Same CTD issue happened to me as well

With some experimentation I think I riddled out at least part of what makes these things work under the hood.
The spacer isn't magically altering the properties of the projectile. Adding, removing, moving, or changing it within the same gun doesn't seem to do anything to the shot's performance.
What it does do, is MASSIVELY reduce beam deflection stress. Which means longer, thinner barrels. In railguns long and thin barrels translate into more velocity, all other things equal. I think what's going on here, is the game calculates beam deflection stress using the length from the "front" of the projectile to the end of the barrel, but acceleration is calculated from the "back" of the projectile to the end of the barrel.
So an extremely long projectile can benefit from a very long barrel, with very little beam deflection stress. Due to the minimum radius on rad shields a needle several meters long would be very heavy, which would offset the benefit, except that spacers allow us to increase the alleged length of the projectile for zero mass.
Basically, it's a buggy imitation of barrel bracing. Though it's vastly more efficient than actual barrel bracing because the "bracing" in this case has zero mass and zero cost.
The most obvious fix would be to calculate beam deflection stress using the full length of the barrel regardless of the projectile's length, though obviously this would nerf long projectiles and payloads across the board. However, with the exception of gun-launched missiles, most normal projectiles are probably not long enough relative to their barrel to notice.

I do have to assume there's an invisible sabot, which reduces the beam deflection and makes these guns viable. Ross128: Yup The catch is that the forces on the barrel are different during firing and at rest. At rest, the rails aren't trying to hug eachother or squeeze the crap out of the projectile.

And my record(I have built one) for a railgun is 1 km/s XD I have a long way to go

Coilguns are slightly better for heavy loads (say 50g) around 8kms. They are never light though.
1g railguns around 20kms beat them all to hell though.....range is much better.
