LINK ENTITY TO CLASS(): Difference between revisions

Latest revision as of 08:05, 1 May 2025

LINK_ENTITY_TO_CLASS() is a C++ macro available in all Source and GoldSrc games. It is used to link a classname to a C++ class.

In the standard Source SDK and Half-Life SDK, the syntax is as such:

LINK_ENTITY_TO_CLASS(editor_classname, CPPClassName)

This will usually look like so:

LINK_ENTITY_TO_CLASS(info_null, CNullEntity)

ReGameDLL_CS uses a modified syntax, adding an additional C++ class for server plugins:

LINK_ENTITY_TO_CLASS(editor_classname, CPPClassName, APIClassName)

This will usually look like so:

LINK_ENTITY_TO_CLASS(info_null, CNullEntity, CCSNullEntity)
