Damage types

The Damage Type property of a trigger_hurt entity lets you choose between many types of damage, but it may be hard to figure out what these types of damage do exactly, so below is a list (for Half-Life 2).

If nothing else is stated, each damage hit will (besides damaging you) make you jerk a little, make your screen flash red if you don't have a HEV suit, or provide red HUD directions to display where the damage is coming from if you have a HEV suit.

The damage caused depends on the current difficulty setting:

• The "Easy" (skill 1) setting causes 25% of the Damage value every half-second.
• The "Normal" (skill 2) setting causes 50% of the Damage value every half-second.
• The "Hard" (skill 3) setting causes 75% of the Damage value every half-second.
• : Always causes 100% of the Damage value every half-second.
