Need help with monster summoning inside a custom instance

Ruhn · June 25, 2024

demon_lair,99,101,1    script    #Demon_Tomb    565,{
    mes "[Tomb]";
    mes "This is the resting place of a great demon";
    mes "named Azhura.";
    next;
    mes "You can summon him thru";
    mes "Nightmarish Ornament and Evil Energy";
    next;
    mes "Put the Nightmarish Ornament";
    mes "and Evil Energy.";
    menu "Yes",yes,"No",-;
    next;
        mes "[Tomb]";
        mes "Come back when you are decided.";
        close;
        end;
yes:
if( countitem(41001) < 2 )
    mes "You didnt have required item!";
else{
    delitem 41001,2;
    mapannounce .Map$, "Prepare for the unleashed evil!!", bc_map;
    goto SummonAzhura;
    }
    end;
    
SummonAzhura:
    monster .Map$,99,106,"Great Demon Azhura",1973,1,strnpcinfo(0)+"::OnKilledAzhura";
    end;

OnKilledAzhura:
    disablenpc "#Demon_Tomb";
    end;

OnInit:
    .Map$ = "demon_lair";
    end;

}

This is my code, the map announce and monster is not being summoned.

No error on Map server

Well, normally you'd use what you did "--en--", or "--ja--". But if you want to pick the names yourself, you can do this:

prontera,99,101,1	script	Demon Tomb	565,{
	mes "stuff...";
	setarray .@mobIds, 1002, 1003, 1004, 1005, 1006;
	setarray .@mobNames$, "Poring 1", "Poring 2", "Poring 3", "Poring 4", "Poring 5";
	
	.@mobIdx = rand(getarraysize(.@mobIds));
	.@mobId = .@mobIds[.@mobIdx];
	.@mobName$ = .@mobNames[.@mobIdx];
	monster .@map$,99,107,.@mobName$,.@mobId,1,.@label_boss$,2;
	end;
}

If you prefer, you can use this approach below as well, same thing (I find it easier to handle in larger scripts, but there's really no difference).

prontera,99,101,1	script	Demon Tomb	565,{
	mes "stuff...";
	setarray .@mobIds, 1002, 1003, 1004, 1005, 1006;

	.@mobId = .@mobIds[rand(getarraysize(.@mobIds))];
	monster .@map$,99,107,'mobNames$[.@mobId],.@mobId,1,.@label_boss$,2;
	end;
OnInstanceInit:
	'mobNames$[1002] = "Poring 1";
	'mobNames$[1003] = "Poring 2";
	'mobNames$[1004] = "Poring 3";
	'mobNames$[1005] = "Poring 4";
	'mobNames$[1006] = "Poring 5";
	end;
}

    mes "[Tomb]";
    mes "This is the resting place of a great demon named Azhura.";

    next;
    mes "Put the Nightmarish Ornament and Evil Energy.";
    menu "Yes", L_yes, "No", L_no;
    
L_no:
    mes "[Tomb]";
    mes "Come back when you have decided.";
    close;

L_yes:
    if (AzhuraSpawned) {
        mes "The Great Demon Azhura is already here!";
        close;
    }
    if (countitem(41001) < 2) {
        mes "You don't have the required items!";
        close;
    }
    delitem 41001, 2;
    mapannounce .Map$, "Prepare for the unleashed evil!!", bc_map;
    set AzhuraSpawned, 1;
    monster .Map$, 99, 106, "Great Demon Azhura", 1973, 1, strnpcinfo(0) + "::OnKilledAzhura";

New problem arises, when i have the instance created, the monster is not showing up xD

Tokei · June 26, 2024

A couple things to learn here:

OnInit applies when the script is loaded, while OnInstanceInit applies when the instance is created. So in your case, you want to use OnInstanceInit.
"demon_lair" is the base map, but that's not the map inside your instance. You want to use instance_mapname("demon_lair");
Likewise, when you're setting up the event label, it is attempting to call it on the base NPC, not the instanced NPC. So you want to use
```
instance_npcname(strnpcinfo(0)) + "::OnKilledAzhura"
```
"set" is a very much outdated command, use "=" instead.
"$AzhuraSpawned" is a global, permanent, variable. It is kept when your server restarts and it is also shared between instances. You want to use 'variable instead.

So your script would look something like this (and using menu is weird):

demon_lair,99,101,1	script	Demon Tomb	565,{
	mes "[Tomb]";
	mes "This is the resting place of a great demon named Azhura.";
	next;
	mes "[Tomb]";
	mes "You can summon him through Nightmarish Ornament and Evil Energy.";
	next;
	mes "[Tomb]";
	mes "Put the Nightmarish Ornament and Evil Energy.";
	next;
	
	switch(select("Yes.:No.")) {
		case 1:
			if ('AzhuraSpawned) {
				mes "The Great Demon Azhura is already here!";
				close;
			}
			
			if (countitem(41001) < 2) {
				mes "You don't have the required items!";
				close;
			}
			
			delitem 41001, 2;
			mapannounce .Map$, "Prepare for the unleashed evil!!", bc_map;
			'AzhuraSpawned = 1;
			monster .Map$, 99, 106, "Great Demon Azhura", 1973, 1, instance_npcname(strnpcinfo(0)) + "::OnKilledAzhura";
			close;
		case 2:
			mes "[Tomb]";
			mes "Come back when you have decided.";
			close;
	}
	
	end;
OnKilledAzhura:
	'AzhuraSpawned = 0;
	end;
OnInstanceInit:
	.Map$ = instance_mapname("demon_lair");
	end;
}

Thanks for the input, managed to figure it out mate.

I'm doing now is how to make it summon a random boss, like i have 5 bosses in array. xD

Ruhn · June 26, 2024

How can i make the npc summon a random mob id

for example this list of mob ids

mobid 1, mobid 2, mobid 3, mobid 4, mobid 5

name 1, name 2, name 3, name 4, name 5

then if the system pick mobid 3 the name should be name 3

monster .@map$,99,107,"--en--",.@MobID,1,.@label_boss$,2;

	'mobNames$[1002] = "Poring 1";
	'mobNames$[1003] = "Poring 2";

	'mobNames$[1005] = "Poring 4";
	'mobNames$[1006] = "Poring 5";
	end;
}

thanks @Tokei , the second one works fine. the first one does not give names.

Ruhn · July 1, 2024

?@Tokei, on this part in which the boss got killed, how can i make this reward every party member in the instance?, also for example the summoned boss is "poring 1" it should only give "poring 1 loot" then for "poring 2" it should only give "poring loot 2" ?

	// spawn mobs
	setarray .@mobIds, 20570, 20571, 20572, 20573, 20574;
	
	.@mobId = .@mobIds[rand(getarraysize(.@mobIds))];
	.@map$        = instance_mapname("demon_lair");
	.@label_boss$ = instance_npcname(strnpcinfo(0))+"::OnMyBossDead";
	monster .@map$,99,107,'mobNames$[.@mobId],.@mobId,1,.@label_boss$,2;
	unittalk $@mobid[0],"Die ! You insolent fool!!";
	end;

OnMyBossDead:  //
	specialeffect2 EF_MVP;
	getitem 41000,50; //


	// trigger other events
	.@map$   = instance_mapname("demon_lair");
	mapannounce .@map$,"He will resurrect, soon!",bc_map;
	donpcevent instance_npcname("Reinfred#fin")+"::OnEnable";
	end;
}
