I’ve told him like 4 times what hitscan characters are, but he just doesn’t get it. I tell him that Widowmaker is hitscan, and he says that she has projectiles and therefore isn’t hitsscan. I’ve told him what the hitscan means, where you click on a target and they take damage without a projectile, but he still doesn’t quite understand how it works and will still yell at me if I say Ashe is hitscan.
The only source of confusion I can think of is that in real life all firearms have projectile travel time but this isn’t the case in the game (has he played Apex? In there all weapons have projectile flight time and bullet drop).
Have him try out Widow vs Hanzo in the firing range at long distance to feel the difference?
Pubg shows this very clearly and is made obvious
