Renaming bots

[guiismiti]

Quick question, just need a confirmation - is it possible to rename bots?

I created this code just now:

		    if(isdefined(self.isbot))
    {
        botname = getSubStr(self.name, 0, 3);
        
        if(botname == "bot")
        {
            number = getSubStr(self.name, 3, self.name.size);
            self.name = "new name #"+number;
            self setclientcvar("name", "new name #"+number);
            iprintlnBold("a bot has been renamed");
        }
    } 
	

I'm aware setclientcvar would never work since bots don't have their own configurations like players do. Still, as a noob, it's worth the try.
Also, it's weird that I can get self.name from a bot but cannot change it.
I'm reading the printed message in game every time the code is read, so, it is reaching the renaming commands.

Hmm... I actually just tried to use 'self.name = ' to rename myself ingame, and it didn't work. Any clues?

Possible but very hard.




Basically you'd need to create a custom scoreboard, killfeed and kill messages, while figuring out how to hide the stock ones.

There might be a way to do it using libcod (See http://killtube.org/showthread.php?1...ing-bots/page2 ) but examples on that thread have been done with cod1.

Yea, I can see the ping is also modified.

You can try it with libcod like explained here:

That is for CoDExtended.

Could you convert it to libcod for those who are unfamiliar with C++? (Myself being one)

When i got time i will start with 'isbot' function for libcod. After that works i will start on 'renamebot'.

1.3

		int __cdecl sub_808C316(int a1, char *dest, int a3)
{
  int v3; // ST14_4@5
  int v5; // [sp+10h] [bp-8h]@2

  if ( *(_DWORD *)(a1 + 452308) == 2 )
  {
    sub_8094A10(0, 0, "%c \"EXE_CANNOTKICKHOSTPLAYER\"", 101);
    v5 = 0;
  }
  else
  {
    if ( dest )
    {
      sub_80B7AB6(dest, (const char *)(a1 + 134216), a3);
      sub_80B7E54(dest);
    }
    v3 = *(_DWORD *)(a1 + 714500);
    sub_808F02E(a1, "EXE_PLAYERKICKED");
    *(_DWORD *)(a1 + 134688) = dword_8423084;
    v5 = v3;
  }
  return v5;
} 
	

		if ( *(_DWORD *)(a1 + 452308) == 2 ) 
	

		if( cl->netchan.remoteAddress.type == NA_LOOPBACK ) 
	

NA_BOT = 0

		void gsc_player_addresstype(int id) {
    #if COD2_VERSION == COD2_VERSION_1_3
        int info_start = *(int *)0x08423084;
        int info_base = *(int *)0x0842308C;
        int info_size = 0xB1064;
        int info_addresstype_offset = 0x6E6D4; // same as 1.2
    #else
        #warning gsc_player_addresstype() got no working addresses
        int info_start = *(int *)0x0;
        int info_base = *(int *)0x0;
        int info_size = 0x0;
        int info_addresstype_offset = 0x0;
    #endif

    int info_player = info_base + id * info_size;
    int addrtype = info_start - *(unsigned int *)(info_player + info_addresstype_offset);
    stackPushInt(addrtype);
} 
	

1.0 offset is 0x6E5C4.

I'm only guessing here but I think he's manipulating the default bot name (Which can be done without libcod by editing cod2_mp with a hex editor, but the bot name is limited to 3 chars without libcod) which affects all bots globally.

If its possible to individually change their name (Without making your own scoreboard/obituary) then by all means prove me wrong =D

62 6F 74 25 64 found it

Also, Game Tracker does not count bots as players, but what if they are renamed? Can't test it, haven't got a server.

I made some progress to rename them. (1.3)

		sub_80B85CE(&dest, (unsigned int)"challenge", v6);
if ( (unsigned __int8)sub_80B2FAA("fs_restrict") )
{
  v7 = (unsigned int)sub_80B8108(&dest, (int)"sv_keywords");
  sub_80B7F0A(&s, 0x400u, "demo %s", v7);
  sub_80B85CE(&dest, (unsigned int)"sv_keywords", (int)&s);
} 
	

Info_SetValueForKey = 0x080B85CE

		result = sub_808BAF8();
v3 = result;
if ( result )
{
  sub_8060DEA("userinfo\n");
  sub_8060DEA("--------\n");
  result = sub_80614EA(v3 + 12); 
	

=

		cl = SV_GetPlayerByName();
if ( !cl ) {
    return;
}

Com_Printf( "userinfo\n" );
Com_Printf( "--------\n" );
Info_Print( cl->userinfo ); 
	

Now i only need to set the name to the client struct.

In SV_GetPlayerByName function:

		sub_80B7AB6(&dest, (const char *)i + 134216, 64); 
	

=

		Q_strncpyz( cleanName, cl->name, sizeof(cleanName) );

I got currently this. I haven't tested or compiled it yet.

		void gsc_player_renamebot(int id) {
    char * key;

    if ( ! stackGetParams("s", &key)) {
        printf("scriptengine> ERROR: gsc_player_renamebot(): param \"key\"[1] has to be an string!\n");
        stackPushUndefined();
        return;
    }
    
    #if COD2_VERSION == COD2_VERSION_1_0
        int info_base = *(int *)0x0841FB0C;
        int info_size = 0x78F14;
    #elif COD2_VERSION == COD2_VERSION_1_2
        int info_base = *(int *)0x0842200C;
        int info_size = 0x79064;
    #elif COD2_VERSION == COD2_VERSION_1_3
        int info_base = *(int *)0x0842308C;
        int info_size = 0xB1064;
    #else
        #warning gsc_player_renamebot() got no working addresses
        int info_base = *(int *)0x0;
        int info_size = 0x0;
    #endif

    int info_player = info_base + id * info_size;
    
    #if COD2_VERSION == COD2_VERSION_1_3
    typedef int (*Info_SetValueForKey_t)(char *s, const char *key, const char *value);
    Info_SetValueForKey_t Info_SetValueForKey = (Info_SetValueForKey_t)0x080B85CE;
    
    Info_SetValueForKey((unsigned int *)(info_player + 12), "name", key);
    char * name = (const char *)(unsigned int *)(info_player + 134216);
    memcpy(&name[0], key, 32);
    name[31] = '\0';
    printf("name = %s\n", name);
    #endif

    stackPushInt(1);
}

You can now download the working version: http://znation.nl/libcod/libcod2_1_3.so (only tested with rcon status)

		bot renamebot("NEW NAME");
