R> Specific Global Item drop

Yonko · July 27, 2020

Hi,

I would like to request a simple script like this. When monster is killed there's a percentage to
drop 1 random item on list(custom list) which bypass their natural drop items see the scenario below(percentage of drop can be configured from 0.01%~1%) on a specific map.

Poring in prt_fild01 drops 1 item on the list together of the its natural item drop(jellopy, empty bottle, unripe apple. sticky mucus, knife[3], apple & poring card) when killed.

Thanks

thank you so much. Last modification is it possible for 0.01~0.99% chances instead of 1%~100% chances?

if (rand(99) < .@chance)

to:

set .@chance, 99; // For 0.99%
or
set .@chance,1; // For 0.01%

and rand must be:

if (rand(9999) < .@chance)

maybe something like :
(I have not tested)

-	script	RandomItem	-1,{
OnNPCKillEvent:
	if (rand(99) > 9) end; // 10% chance of success
	set .@map$,strcharinfo(3);
	switch(killedrid){
		case 1002:     // IF PORING
				if (.@map$ == "prt_fild01") 
					getitem 4005,1; // Santa poring card
				else if (.@map$ == "prt_fild02") 
					getitem 2236,1; // Santa poring hat
				break; 
	}
	end;
}

or alternatively

-	script	RandomItem	-1,{
OnNPCKillEvent:
	if (rand(99) > 9 || strnpcinfo(3) != "prt_fild01") end; // 10% chance of success, only works on prt_fild01

	.setarray .@Items,4005,2236;  		// Item array
	set .@rand,rand(1,getarraysize(.@items);
	getitem .@Items[.@rand],1; 
	end;
}

Note: This will add a item drop but not bypass any drops. Eg. if you add poring card on the custom list, you may drop 2 poring card at the sam time.

For bypass itemdrop you may have to use *addmonsterdrop but this has no conditional. It means the any monster will drop that item, doesnt matter map or anything...

getitem will give the item directly to your inventory, if you want the monster to drop an item "on top" of their natural drops then you can do like below

// 1. Go to your src/map/script.cpp
// 2. Add below code before "case BL_PC:	//Get Character Position"
// case BL_MOB:
//	if (script_hasdata(st,6)) 
//		bl = map_id2bl(script_getnum(st,6));
//	break;
// 3. Recompile your server
// 4. Add below script

-	script	CustomDrop	FAKE_NPC,{
	OnNPCKillEvent:
		for (.@i = 0; .@i < .size; .@i += 4) {
			if (killedrid == .data[.@i]) {
				if (rand(10000) < .data[.@i + 3]) {
					getmapxy .@map$, .@x, .@y, BL_MOB, killedgid;
					.@amt = .data[.@i + 2];
					while (.@amt) {
						makeitem .data[.@i + 1], 1, .@map$, .@x, .@y;
						.@amt--;
					}
				}
			}
		}
		end;
		
	OnInit:
		// <mob_id>, <item_id>, <item_amount>, <chance>
		// Chance ========================
		// 10000 	= 100%
		// 1000		= 10%
		// 100		= 1%
		// 99		= 0.99%
		// 50		= 0.50%
		// 1		= 0.01%
		// ===============================
		setarray .data[0], 
			1002, 607, 2, 10000, // poring will drop 2 ygg berries on the floor with 100% chance
			1002, 608, 3, 10000; // poring will drop 3 ygg seeds on the floor with 100% chance
		
		.size = getarraysize(.data);
		end;
}

Really usefull! Tks for that. Why this is not commited??

Any chance of both mine or your script be laggy??

There should be no issues if you are using latest rAthena (C++ version)

There is getunitdata to retrieve x y for monster. Sample untested :

@Capuche Yeah right i always remember setunitdata and getunitdata for their main attributes only and tend to forget the UMOB_X and UMOB_Y constants as part of it
