friend class?

[stefanhendriks]

Does anybody know what this line means? I found CBotManager somewhere, as a friend class in the player.h

what is a friend class? I do not see a definition of it somewhere?

class CBasePlayer : public CBaseCombatCharacter
{
public:
 DECLARE_CLASS( CBasePlayer, CBaseCombatCharacter );
protected:
 // HACK FOR BOTS
 friend class CBotManager;
 static edict_t *s_PlayerEdict; // must be set before calling constructor

it's a class that when these two meet, they greet each other and have a drink together.

*edit*
btw, I'm at 13% downloading HL2

argh, So there you have it. Unbelievable that you have a FRIEND class so you can bypass protected/private data. Well that makes a lot of use then for protected/private stuff.

still odd that the code compiles without any definition of the friend class in the hl2 sdk. But then again i did not read the entire page and could have missed something. I don't feel well today.

I will burn some files for you PMB, and i hope to post it tomorrow.

"friend" is a standard C++ keyword, just like "const" or "virtual", that's why you don't need to define it...

Million thanks for the CD Stefan

The best way to remember this is...

"In C++, a friend is allowed to get at your private parts".

I assume it would have to be a REAL good friend.

lol @ botman

I use "friends" for classes that are related, ie CBotManager and CBot.
