Hooking into HL2 DLL ?

Heh-heh!

Just tossing this...
Maybe the hooking method isn't impossible, what about implementing the functionality of the interface factory in the hook DLL ? We would "just" need to know about a particular version of the interface and stick to it (which involves of course the need to know where to read and write for this particular version). It sounds like it would work OK for one side of the interface, but I'm wondering about the other...

You know it might work if the netcode was hooked, but that would probably be more evil than hooking the interfaces.

huh ? I don't get it again. I wasn't talking about netcode, but about the virtual function tables... ???

However the SDK hasn't been updated (?), so currently we can't use the CBasePlayer class.
I don't know if Valve changed the CBasePlayer to stop us using it or if it was to fix some bugs. I think it's just something they had to do to get the bots working.

rofl well i only converted code that i considered nescesary to do it directly through cBasePlayer, so in my case my bots should still work fine

Also, if any SDK release comes soon, we can hope for a fully basic bot plugin from Valve, which i find very neat from them!

I haven't done anything special, just refreshed the SDK content which might have changed stuff.

I have no joy here, I've refreshed game content, still no dice ! same thing happens (engine->createFakeclient() crashes.)

Yeah, I dived in a bit quick with using lots of useful stuff within the CBasePlayer, like choosing and changing weapons, detecting damage etc. So I'm gonna wait a week until I start undoing it all.

My stupidity getting mixed up with CBasePlayer & IServerGameClients Processusercmds (i was messing with the ubframe and not steve`s template) and wasn`t using my brain .

I am saying there is always the brute force method of simulating an actual client connecting. You could pass the server data to the bots through a plugin.
