This reminds me of my physics professor shooting a falling monkey with a laser-sighted railgun 
On a related note, most of the weapons in dust do not use bullets. If they put in artillery, I'm sure they'd give that ballistics. I'd love mobile artillery! Air burst plasma shells ftw. If you want the mechanic, I'd bet it's what's used on the mass driver. |

If you go to the market and look under turrets, they have categories for artillery and lasers. It would make sense if artillery functions like the Mass Driver.
They shouldn't add ballistics to all weapons because different weapons are different. Lasers, for example, are beams of light. Plasma is plasma, and reacts differently than mass in a solid, liquid, or gas state. I have no idea how they describe firing plasma from a gun, it might even not be when it leaves the gun. You can make plasma with a high power pulsed laser (google LPP, Laser Produced Plasma). I don't know for sure, but I'd bet that adding ballistics to weapons won't be a big drain on the servers. The server has to calculate the trajectory of the regular bullets anyways. Again, there are weapons in UT3/DUST that already use a ballistics mechanic.
I would love to see some physics for a mobile artillery :3. I'm ready to do this right now! I have Mathematica + MATLAB all ready to go on a computer to figure out and compute velocities, air resistance, gravity, angular momentum, etc., etc.! |

And the rail based sniper rifle needs travel time, bullet drop would be smaller then dispersion on a real life bullet based sniper so can be ignored. But a running target could travel a few meters in the 1/4 second travel time to max range.
Sniper rifle would have 28cm or 11 inches of drop at 600m at listed muzzle speed, standard issue u.s. army sniper have 1-3 moa or up to 20.6 in or 52cm of dispersion. So the bullet drop is negligible for rail based sniper, if one wanted it could be faked by having any dispersion only lower and never raise the shot. And if there is no dispersion why worry about the drop. Even a moving heavy could move 86cm during flight time though.
Railguns (hand-held) can already fire a projectile at a velocity greater than 3,000 m/s, which faster than the rifle in-game (I believe the in-game rifle is 2,500 m/s, and forge is 7,500 m/s -ish, but not @ my ps right now). That being said, I'm pretty sure the projectile from the sniper rifle fires at a velocity greater than 2,500 m/s. (All velocity measurements taken as the projectile exits the muzzle). I'm pretty sure the projectile has a muzzle velocity higher than the listed value already in game.
Pretending that there are no other external forces on a projectile fired at 2,500 m/s out of the sniper rifle, it would take 0.24 seconds to traverse 600m. According to the internetz, top speed of Usain Bolt is 12.27 m/s. In 0.24 seconds, Usain Bolt could move about 3cm. I'm just going to assume that you took the speed actually listed/used in game for the heavy. I have tried a heavy, and trust me, I do not feel like I am moving at speeds many times faster than Usain Bolt ever could. I guess if the devs add projectiles, they could fix the values listed in text? Maybe if the devs multiply listed values by 10,000 it would be more accurate. It's only 1/4th the speed of light!
Also, the composition of air on the planets and moons is a factor to consider (air resistance, but it may be a different composition of air with a different density), along with the gravitational forces. I'm not sure if the railgun puts a spin on the projectile, which would give it angular momentum, which means that further calculations need to be made. You might even have to factor in the circumference of the planet/moon and the speed at which it is rotating if it's fast enough and the projectile is going far enough, and wind if there is an atmosphere on the planet/moon.
I'd love it if the devs did a quick formula to calculate gravitational forces/air resistance on ballistic projectiles, preferably for artillery only. Sway, recoil, removal of one-way walls, variable scopes, and terrain that is more difficult to hide in should fix snipers imo. If they just add bullet drop, people will aim higher and it will remain the same. Unless the devs add a range calculator to whatever the rifle is aimed at, slower bullet speeds will just make sniping more of a random chance than it needs to be. |
