The Simple Weapon Trace System is a system comprised primarily of one component, the SimpleWeaponTrace_component. This component can be attached to any weapon, projectile, character, or any other intended damage-dealing entity and activated at will to perform traces that interpolate between frames with optional substepping. Sockets or collision shapes (box and sphere compatible) can be utilized to perform the traces and collision shapes can be assigned custom damage modifiers through component tags.
