List of codepointers

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.
