Knockback

Knockback is the action of being moved from one tile to another by means of a damage source. In DoomRL terms, rather than saying that a player was knocked back some number of tiles, it is more common to use the expression "took X knockback" where X is the number of tiles displaced.

Knockback calculations are performed as follows:

• Damage source changes the amount of damage required per tile of knockback.
  • Melee weapons never cause knockback
  • Most ranged weapons require 12 points of damage per tile of knockback
  • Shotgun weapons and most explosions (as well as the direct explosive missile) require 7 points of damage per tile
  • BFG explosions require 14 points of damage per tile
  • Rocket jump explosions require 2 points of damage per tile
• Any knockback modifiers affect the overall knockback rate.
  • If wielding the Butcher's Cleaver, Longinus Spear, or Dragonslayer, any knockback taken is halved.
  • If a player has ranks in the Badass Trait, reduce the number of tiles knocked back by one per rank.
  • Any number modifiers due to armor affect knockback as a percentage (100 + modifer), which then rounds to the nearest tile for knockback purposes.
