Hitscan class final

Fires a weapon's rays into the world and reports where they landed.

The spread is mostly not random

A shotgun's pellets follow a fixed pattern — one down the middle and the rest on a ring — with only a small random jitter on top. Fully random spread makes the same shot at the same range do wildly different damage, which reads to a player as the game cheating rather than as variance. A fixed pattern means a shotgun at close range always kills what it is pointed at, and that reliability is the whole character of the weapon.

The jitter exists so two consecutive shots do not draw identical tracers.

What it tests against

The collision world, not the render meshes. Those are two different things — a wall is one merged surface per material by the time it is drawn — and the player's expectation is set by what they cannot walk through.
