Shells are the ejected particles of a round. These can be a huge variety of objects, but they are generally MOSParticles with an animation of a spinning casing. Because the shell is defined in the round, tracer rounds can have shells separate from those of the regular rounds. They are ejected at a velocity defined by the round, at a position on the HDFirearm defined by said HDFirearm, at a spread and angular velocity range defined by the HDFirarm, and at a hard coded angle, which is backwards-upwards. Negative velocities result in a forward-downward angle.
'Shell' is actually an incorrect term for what they are in CC, Casing is a more fitting term generally. But Shell is the term used in the code.
Shells do not produce any recoil. You can use this combined with negative shell velocity variable on the round to make tool or a weapon that can fire an object with high mass without worrying about your actor exploding from the recoil force that is usually processed when heavy projectile is used as a round instead of a shell. A drawback on this is that the hardcoded angle causes the projectile to fly at a diagonally downwards angle.
