Hello,

when I try to use the IBotManager interface to add a bot player in TF2, the server crashes and I don't have an idea how to fix this.

Based on the serverplugin sample located in...
\hl2sdk-ob\utils\serverplugin_sample
... I tried to add a bot with the following code:

PHP Code:

void BotAdd_f() {
    if ( !botmanager ) return;
    edict_t *botEdict = botmanager->CreateBot( "botName" );

    IPlayerInfo *info = playerinfomanager->GetPlayerInfo(botEdict);
    info->ChangeTeam(3);
    helpers->ClientCommand(botEdict,"joinclass soldier");
}
ConCommand cc_Bot( "plugin_bot_add", BotAdd_f, "Add a bot." ); 


Here is the command "plugin_bot_add" which should create a bot named "botName" on the blue team as soldier. But after running that command I got a crash.

WinDbg's console looks like this:

ModLoad: 14090000 140be000   e:\tf2\orangebox\tf\addons\serverplugin_empty.dll

I also tried it with a sourcemod extension with the following code in a native function:

PHP Code:

cell_t AddBot(IPluginContext *pContext, const cell_t *params) {
    edict_t *edict = botmanager->CreateBot("bot_01");
    return 1;
} 


But this does crash the server, too, when i use "AddBot" in my plugin.

Does someone know about that problem or know how to fix this?
I wasted days into it to get it work, but nothing helped.

Thanks in advance

Thats what happens when you rely on outdated headers from the SDK. If they change something then its going to do exactly what your describing.

You will need to do this the proper way and get the sigs, and call them/hook them/detour them/etc.

IBotManager is a public interface, the offsets should be correct.
Try engine->CreateFakeClient()

[Tauphi]

I already tried engine->CreateFakeClient() ... it worked, but it spawned a bot without a gun and it seemed that i cant let him move or so ...

but i didn't try soo much ... will do it again now ...

btw...
what is the difference between the offical ibotmanager interface function CreateBot and CreateFakeClient ?

[Tauphi]

ok ...

engine->CreateFakeClient() does not work, too...
the edict does not have an IBotController...

PHP Code:

edict_t *edict = engine->CreateFakeClient("Bot01");
IBotController *botc = botmanager->GetBotController(edict); 


botc is always NULL ... so im not able to call the RunPlayerMove function :-/

CreateBot does not work ... CreateFakeClient does not work ...
Any other ideas?

BTW: the author from rcbot told, that the IBotManager interface is broken/outdated since the Scout update in TF2 ... Does this mean, that only valve is able to "fix" this?

It may be your interface version is the one from the SDK. What are you using to assign the botmanager?

GET_V_IFACE_CURRENT or GET_V_IFACE_ANY?

[Tauphi]

PHP Code:

bool Sample::SDK_OnMetamodLoad(ISmmAPI *ismm, char *error, size_t maxlen, bool late) {
    GET_V_IFACE_CURRENT(GetServerFactory, botmanager, IBotManager, INTERFACEVERSION_PLAYERBOTMANAGER);
    return true;
} 


but i did try it with GET_V_IFACE_ANY, too. Both don't work

If the interface definitions have changed it's possible to reverse engineer new ones from the binaries.

I'll try remember to have a look when I next have it open.

I said they changed but noo, just had to try and contradict me.

I smell competition.
