on hit

The hit script event is sent by the damage source to NPCs and props when the the entity is damaged. ^&param1 will be set to the damage received by the entity while ^$param2 is set to the weapon type if the damage source is the player: spell, bare, dagger, 1h, 2h, arrow or (for NPC targets only before Arx Libertatis 1.3) summoned if the damage is from a summoned entity. In this case, the event ^sender will be the player.

With Arx Libertatis 1.3 or newer, ^$param3 holds the spell ID or entity ID of the weapon or summoned entity used to inflict the damage and ^$param4 specifies the damage type flags as used in the dodamage and damager commands:

f	Fire
m	Magical
p	Poison
l	Lightning
c	Cold
g	Gas
e	Metal
w	Wood
s	Stone
a	Acid
o	Organic
r	Drain life
n	Drain mana
n	Push

Spell IDs are made up of the spell name followed by _ and then a unique instance number. Use the if isin command to check for spell or damage types:

 if fireball isin ^$param3 {
   // Hit by a fireball
 }
 if l isin ^$param4 {
   // Hit with lightning damage
 }

For NPCs, scripts can prevent the damage to the entity by responding to the hit event with refuse.

When 0 life or durability is reached for NPCs or props, the die or break events are sent respectively.
