Damage Types

From Second Life Wiki
Jump to navigation Jump to search

Damage types are an additional integer field that is passed along with the damage amount.

Whenever damage is dealt to an avatar, or an object that can process damage, an additional damage type integer is passed along to the on_damage and final_damage events through the llDetectedDamage function. It can also be retrieved via OBJECT_DAMAGE_TYPE on llGetObjectDetails for objects that use collision damage via PRIM_DAMAGE or REZ_DAMAGE_TYPE.


Specification

The damage type integer can match a default DAMAGE_TYPE_*, a custom damage type integer such as from the community damage types or for your own combat system, or even go further to repurpose the damage type fields for contained systems.

For example such as using bitshifting and/or bitmasks to achieve dual or triple damage type systems and/or sub types. Or using bit flags for your own options and enumerations. However be wary that repurposing the damage type field to such extents can create incompatibility with other systems that may process damage. Such as a third party damage report HUD the avatar may be wearing. Of course a fully self-contained/private system on the other hand does not need to worry about such issues.
