Hitscan

Hitscan attacks hit or miss their target the very moment the attack is launched, and therefore cannot be dodged. All melee and bullet attacks work like this; there are no projectiles involved, invisible or otherwise. Melee attacks have a range of 64 units and bullet attacks a range of 2048 units.

Melee attacks are monster and weapon specific, but the damage done by a single bullet is a fixed (though randomized) value. The damage caused by a ranged hitscan attack only varies (excluding the randomization) according to the number of bullets fired by the weapon/monster. In addition, the damage dealt by player and monster bullet hitscan attacks is slightly different: player bullets do 5 to 15 and monster bullets 3 to 15 hit points of damage.
