Editing List of codepointers

This '''list of codepointers''' is a list of all the action routines which can be performed by [[thingtype|things]] from [[EDF]] [[frame]]s. 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 in the DECORATE syntax they will have to use the '''offset'''(''misc1'', ''misc2'') specifier. They all have DECORATE-friendly equivalents however.

'''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.
