// Another GET-API routine, another interface version.
|
|
//
|
|
// Added 5/2003 based on information from Leon Hartwig and Alfred Reynolds,
|
|
// in order to address observed problems with hitboxes not matching between
|
|
// client and server, in CS and DOD.
|
|
//
|
|
// Based around code apparently added to the g_engine around 1/2002,
|
|
// seemingly to address "the old CS hitbox problem", where "the client was
|
|
// doing custom player model blending and the server had no idea what was
|
|
// going on".
