Private Data
I don't know if this is just a "duh" thing to people, but I thought I'd share this anyways. I have found a fairly simple way to access an enitity's private data. This will of course be mod-specific, but for things like money in CS:S it doesn't really matter how that will be read or modified. Anyways this is basically how to do it:
Code:
edict_t *pPlayer;
pPlayer->GetUnknown();
Using that you can access private data like we could in HL1 with pvPrivateData. This may not be the best way to do it, but it certainly is _a_ way that works.
So here is some code that demonstrates some of the offsets I have found already. The offsets will of course change when CS:S is updated, so be aware of that.
Code:
/* Helper functions */
bool is_user_valid(edict_t *pPlayer) {
if ( !pPlayer || pPlayer->IsFree() || Q_stricmp(pPlayer->GetClassName(), "player") != 0) {
return false;
}
return true;
}
bool is_user_connected(edict_t *pPlayer) {
IPlayerInfo *info = playerinfomanager->GetPlayerInfo(pPlayer);
return info->IsConnected();
}
/* Private data functions for CS:S */
int cs_get_user_money(edict_t *pPlayer) {
if (!is_user_valid(pPlayer) || !is_user_connected(pPlayer))
return 0;
return *((int *)pPlayer->GetUnknown() + 863);
}
void cs_set_user_money(edict_t *pPlayer, int amount) {
if (!is_user_valid(pPlayer) || !is_user_connected(pPlayer))
return;
*((int *)pPlayer->GetUnknown() + 863) = amount;
}
bool cs_get_user_buyzone(edict_t *pPlayer) {
if (!is_user_valid(pPlayer) || !is_user_connected(pPlayer))
return false;
int flags = *((int *)pPlayer->GetUnknown() + 1130);
if (flags & (1<<8))
return true;
return false;
}
Edit: Updated offsets for December 16th update. |
