This list of codepointers is a list of all the action routines which can be used in EDF frames. They are common for all games, so for example Heretic codepointers can be used in Doom.

You can specify the codepointers with or without their internal A_ prefix, even inside DECORATE state syntax. For simplicity, they will be referred in this wiki without the prefix.

Note that some codepointers, inherited from MBF, use the misc1 and misc2 frame properties, instead of the more general args list. Side effects aside, this also means that they will not be usable in the DECORATE syntax, but they all have DECORATE-compatible equivalents.

IMPORTANT: Do not provide more nonzero arguments to the codepointers than specified in the reference. Doing so may break forward compatibility with versions of Eternity that implement new functionality to codepointers.

Map objects

Explosions

These are for area-of-effect damage, common with projectiles and bombs (e.g. barrels):

  • Explode: classic DOOM splash damage. Deals 128 damage in a 128 radius.
  • Detonate: like Explode, but uses the thingtype "damage" field.
  • DetonateEx: complete parameterized explosion.
  • HticExplode: Heretic-compatible explosion, with predefined special behaviour depending on parameter.
  • Mushroom: large mushroom explosion, from MBF.
  • Nailbomb: explosion with bullet shrapnels, from SMMU.

Projectile control

  • Tracer: one of the required components for homing missiles

Monster behaviour

These are designed mainly for monsters and similar shootable objects. The ones here are especially useful for any generic monster.

  • Look: stand in guard, looking for targets.
  • Chase: pursue a target and check for attack.
  • FaceTarget: turn to target, look around it if it's partly invisible.
  • CPosRefire: go to seestate if target is out of sight. Typical with sustained fire monsters.
  • SpidRefire: like CPosRefire but with slightly different reaction times.
  • Pain: play the pain sound.
  • Fall: typical during death, this removes the SOLID flag.
  • Scream: plays the death sound.
  • XScream: makes the extreme death (gib) sound.
  • BossDeath: special monster death functions (such as Baron death in E1M8)
  • KeenDie: open 666-tagged doors on death of all monsters of the same species.

Player avatar behaviour

These are designed for the player-controlled thing (e.g. DoomMarine).

Various effects

These specials are more advanced than what's available in the classic games and do not belong specifically to projectile or monster usage

  • Face: face a specified angle
  • Stop: set velocity to 0
  • Turn: turn around a specified angle
  • Spawn: create another object on top of this one
  • LineEffect: activate a tag using a special
