As about your question on modded thing.
The "m_upgradeBitVec" bits are undocumented. If you find more information on them, I would be also interested in it.
The guy who modified the plugin, uses the bit:
which is according to (his) description means "weapon larger mag/clip size".
And since it is undocumented (?) I can say nothing about it.
The more simplified code of that thing as a stand-alone plugin would be something like:
PHP Code:
public void OnClientPutInServer(int client)
{
const int WEAPON_CLIP_BIT = 0x100000;
SetEntProp(client, Prop_Send, "m_upgradeBitVec", GetEntProp(client, Prop_Send, "m_upgradeBitVec") | WEAPON_CLIP_BIT);
}
maybe with bot check and +timer / join team event.
P.S. This is much likely can also be just the highest bit of DWORD of clip size value. Need to look the table. Somebody can check in "Double equipment" plugin to prove.
