Code part #1:

public void OnPlayerSpawn(Event event, const char[] name, bool dontBroadcast) {
	if ( !g_bIsDRmap )
		return;

	int iClient = GetClientOfUserId( event.GetInt( "userid" ) );

		CreateTimer( 0.2, RespawnRebalanced, GetClientUserId( iClient ) );
	}

	if ( g_bOnPreparation )

}

Code part #2:

	g_iLastDeath = iNewDeath;
	int iTeam;
	for ( int i = 1; i <= MaxClients; i++ ) {
		if ( !IsClientInGame( i ) )
			continue;

			g_iQueuePriory[ i ] = 1;
		}
		else if ( iTeam != TEAM_RED )
			ChangeAliveClientTeam( i, TEAM_RED );

		CreateTimer( 0.2, RespawnRebalanced, GetClientUserId( i ) );
	}

RespawnRebalanced code:

public Action RespawnRebalanced(Handle timer, any data) {
	int iClient = GetClientOfUserId( data );
	if ( iClient && !IsPlayerAlive( iClient ) )
		TF2_RespawnPlayer( iClient );
}
