You must create a loop to cycle through all the Party members one by one and set the variable on each member. Here I will show you an example of how to Set a Varaible named "KILLED_BOSS" to a value of 1, within a conversation "Actions Taken" node. void main() { object oPC = GetPCSpeaker(); if(!GetIsPC(oPC))return; object oPartyM = GetFirstFactionMember(oPC); // If not in party avoid loop if(!GetIsObjectValid(oPartyM)) { SetLocalInt(oPartyM,"KILLED_BOSS",1); return; } while(GetIsObjectValid(oPartyM)) { SetLocalInt(oPartyM,"KILLED_BOSS",1); oPartyM = GetNextFactionMember(oPC); } }
