modifying vending skill

[serverkid 1]

will this make the vendor immune to monster's attacks?

 

 

case MC_VENDING:

if (sd) {

//Prevent vending of GMs with unnecessary Level to trade/drop. [skotlex]

if ( !pc_can_give_items(sd) )

clif->skill_fail(sd,skill_id,USESKILL_FAIL_LEVEL,0);

else {

sd->state.prevend = sd->state.workinprogress = 3;

sd->state.monster_ignore = 1;  //will this work?

clif->openvendingreq(sd,2+skill_lv);

}

}

break;
