The builtin functions are called "etof" and "ftoe". "etof" returns the number of the edict/entity, while "ftoe" returns the edict/entity of a number. These functions were added to the QSG standard by using the Enhanced BuiltIn Function System (EBFS) with the numbers #108 and #109. If you want to add these functions to your own engine, you should add the EBFS before. In PR_CMDS.C add the following code anywhere before the builtin variables...
// 2001-09-25 New BuiltIn Function: etof() by Maddes start
/*
=================
PF_etof
float etof (entity)
=================
*/
void PF_etof (void)
{
G_FLOAT(OFS_RETURN) = G_EDICTNUM(OFS_PARM0);
}
// 2001-09-25 New BuiltIn Function: etof() by Maddes end
// 2001-09-25 New BuiltIn Function: ftoe() by Maddes start
/*
=================
PF_ftoe
entity ftoe (float)
=================
*/
void PF_ftoe (void)
{
edict_t *e;
e = EDICT_NUM(G_FLOAT(OFS_PARM0));
RETURN_EDICT(e);
}
// 2001-09-25 New BuiltIn Function: ftoe() by Maddes end
... and to the EBFS data array add ...
{ 108, "etof", PF_etof }, // 2001-09-25 New BuiltIn Function: etof() by Maddes
{ 109, "ftoe", PF_ftoe }, // 2001-09-25 New BuiltIn Function: ftoe() by Maddes
Done. |
