What is hitscan
In shooting games, hitscan is a gunplay mechanic where bullets have instant travel time to hit target.
In the game, whenever a shot is fired, the game will perform a simple calculation, it will shoot a ray out of the gun and scan whether or not that shot has hit a target, therefore, hitscan.
Hitscan vs projectile
A lot of shooters use a projectile system, when a gun is firing, the game will actually fire out a physical object and calculate bullet velocity, droop and wind (sometimes). Projectile shooting is a lot more realistic compared to real world gun physics, but is computationally more expensive.
