Zombie Lobby Size (18 Players)

Increasing the zombie lobby size

This will cover modifying game scripts to support more than 4 players. This tutorial assumes you know how to modify core game scripts.

Modifying _zm.gsc

Find the following:

level.player_too_many_players_check = true;

And change it to:

level.player_too_many_players_check = false;

Next, find:

		case 4:
			n_delay = 0.67;		// 0.95 == 0.1 @ round 60
			break;

And change it to:

		default:
			n_delay = 0.67;		// 0.95 == 0.1 @ round 60
			break;

Modifying _zm_laststand.gsc | .csc

Find the following loops in each file under init:

for( i = 0; i < 4; i++ )

And change the number ‘4’ to however many players you want to allow:

for( i = 0; i < 18; i++ )

Next find:

level.player_name_directive=[];
level.player_name_directive[0] = &"ZOMBIE_PLAYER_NAME_0";
level.player_name_directive[1] = &"ZOMBIE_PLAYER_NAME_1";
level.player_name_directive[2] = &"ZOMBIE_PLAYER_NAME_2";
level.player_name_directive[3] = &"ZOMBIE_PLAYER_NAME_3";

And add as many slots as you need to the array:

level.player_name_directive=[];
level.player_name_directive[0] = &"ZOMBIE_PLAYER_NAME_0";
level.player_name_directive[1] = &"ZOMBIE_PLAYER_NAME_1";
level.player_name_directive[2] = &"ZOMBIE_PLAYER_NAME_2";
level.player_name_directive[3] = &"ZOMBIE_PLAYER_NAME_3";
level.player_name_directive[4] = &"ZOMBIE_PLAYER_NAME_4";
level.player_name_directive[5] = &"ZOMBIE_PLAYER_NAME_5";
level.player_name_directive[6] = &"ZOMBIE_PLAYER_NAME_6";
level.player_name_directive[7] = &"ZOMBIE_PLAYER_NAME_7";
...

Don’t forget to precache them:

#precache( "string", "ZOMBIE_PLAYER_IS_REVIVING_YOU", "ZOMBIE_PLAYER_NAME_0" );
...

Modifying zclassic.gsc | zclassic.csc

Add the following under init in the GSC file:

	for ( i = 4; i < 18; i++ )
	{
          // Hardcoded clientfields per-player, each require a bitlen of 3.
		clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_damage", VERSION_SHIP, GetMinBitCountForNum( 7 ), "counter" );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_normal", VERSION_SHIP, GetMinBitCountForNum( 3 ), "counter" );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_torso", VERSION_SHIP, GetMinBitCountForNum( 3 ), "counter" );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_neck", VERSION_SHIP, GetMinBitCountForNum( 3 ), "counter" );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_head", VERSION_SHIP, GetMinBitCountForNum( 3 ), "counter" );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_melee", VERSION_SHIP, GetMinBitCountForNum( 3 ), "counter" );
	}

Add the following for the init in csc:

	for ( i = 4; i < 18; i++ )
	{
          // Hardcoded clientfields per-player, each require a bitlen of 3.
		clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_damage", VERSION_SHIP, GetMinBitCountForNum( 7 ), "counter", undefined, !CF_HOST_ONLY, !CF_CALLBACK_ZERO_ON_NEW_ENT );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_normal", VERSION_SHIP, GetMinBitCountForNum( 3 ), undefined, !CF_HOST_ONLY, !CF_CALLBACK_ZERO_ON_NEW_ENT );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_torso", VERSION_SHIP, GetMinBitCountForNum( 3 ), undefined, !CF_HOST_ONLY, !CF_CALLBACK_ZERO_ON_NEW_ENT );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_neck", VERSION_SHIP, GetMinBitCountForNum( 3 ), undefined, !CF_HOST_ONLY, !CF_CALLBACK_ZERO_ON_NEW_ENT );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_head", VERSION_SHIP, GetMinBitCountForNum( 3 ), undefined, !CF_HOST_ONLY, !CF_CALLBACK_ZERO_ON_NEW_ENT );
          clientfield::register( "clientuimodel", "PlayerList.client" + i + ".score_cf_death_melee", VERSION_SHIP, GetMinBitCountForNum( 3 ), undefined, !CF_HOST_ONLY, !CF_CALLBACK_ZERO_ON_NEW_ENT );

NOTE: DLC maps, and custom clientuimodels ALL need to be registered for your TARGET lobby size. Failure to do so will result in a hard crash.
