Drop rate issue

[xRyusuke]

I am having trouble lowering MVP card drop rate.

for example:

Now I my mvp card is 10x normal drop rate, which make every mvp drop card at 0.10%

I want to edit so that a certain few mvp drop card at 0.05% and 0.01%

But in the database, the card drop rate is already set at 1 which is 0.01% and I think it couldnt support 0.5 or 0.1 value in the database.

What can I do instead of editing all the mvp card drop rate?

[GM Takumirai]

use the custom drop by Emistry

-	script	Sample	-1,{
function CustomRateCard;

OnNPCKillEvent:
// CustomRateCard( <MobID>,<CardID>,<Rate> );
// Rate : 1 = 0.01%  /  1000 = 10%  /  10000 = 100%

CustomRateCard( 1634,673,1500 );
CustomRateCard( 1635,671,1000 );
CustomRateCard( 1636,673,1500 );
CustomRateCard( 1637,671,1000 );
CustomRateCard( 1638,673,1500 );
CustomRateCard( 1582,4174,500 );
CustomRateCard( 1120,4047,500 );
CustomRateCard( 1096,4054,500 );
CustomRateCard( 1086,4128,1 );
CustomRateCard( 1002,673,300 );
end;

function	CustomRateCard	{
if( killedrid == getarg(0) && rand( 10000 ) <= getarg(2) ){
		getitem getarg(1),1;
		announce "[ "+strcharinfo(0)+" ] get 1 "+getitemname( getarg(1) ),0;
}
return;
}

}

- dont forget this

go to your mob_db.txt

- remove the cards that is drop by the monster.. make it 0,0

where do I place and load this script?

It does work for item and equipment as well right?

Edited August 4, 2012 by xRyusuke

[Emistry]

it work for any item you put for each monster.

just make sure you remove the same item in the mob_db.txt so that the monster wont drop it twice.

http://rathena.org/wiki/Adding_a_Script

another way, edit every mvp / boss in mob_db.txt to change the drop rate

[xRyusuke]

will @mi show the drop rate of items using that script?

[Emistry]

no.

this is a indenpendent script ...@mi wont show the rates.

@mi only read the data inside the mob_db.txt and not other script that related to it.

[xRyusuke]

ok, thank you!

[Euphy]

You don't need a script, there's a DB file for this now:

https://rathena.svn.sourceforge.net/svnroot/rathena/trunk/db/mob_item_ratio.txt

[xRyusuke]

Hi Euphy, can you teach me how to implement that into my server?

because mine doesnt have it yet.

[Mystery]

This was implemented in rAthena r15521.. =/ Im guessing you're using eAthena or 3CeAM? Or maybe rAthena thats 6 months outdated? o_o

But, with that trac changelog, you can implement it yourself by following the changes and applying it manually into your server.

[xRyusuke]

I am not so sure about my version, it shows r679M.

I am using 3CeAM

I copy pasted it in, bot how do i load it?

[Mystery]

For the sql logs part, you need to change that in your SQL db. The rest is a new DB addition and source changes. For source changes you need to recompile your server.

[xRyusuke]

can you link me to a guide?

I am at a lost

[Mystery]

Link you to a guide for recompiling?

How to recompile (Debian)

How to recompile (CentOS)

Here's an overall Compiling guide http://rathena.org/wiki/Compiling

[xRyusuke]

if I just add in the https://rathena.svn.sourceforge.net/svnroot/rathena/trunk/db/mob_item_ratio.txt

I dont need to recompile everything right?

what do i need to change ?

[Emistry]

// - This file is reloaded by @reloadmobdb.

If you're not using rAthena, just use Emistry's script. You'd have to manually diff your source with r15521 (as Mysterious posted) for the database file to work.

[xRyusuke]

ahh... I see

Too bad 3CeAM does not support it by itself

[miczster]

I put all cards drop 10000/10000 in the config/battle =100% card drop

now I want to make mvp cards example phreeoni 20% drop

so ill do this ( mob_item_ratio)?

ItemID,Ratio{,MonsterID}

4121,2000,1159

I don't get it much yet, sorry....
