Predefined damage types

From ZDoom Wiki
Jump to navigation Jump to search

This is a list of predefined damage types, and their means-of-death (MOD) constant names and values. Note, the constants are only readable in ACS and are not exposed to ZScript, but they are associated with specific ZScript-readable damage types.

ACS functions and action specials may require either a damage type name or the MOD constant/value. Creating custom damage types is possible.
