H5 Item Drop From NPC


Question

Posted

Hello, i have a question regarding H5. Because i'm changing the whole drop system and i would like to know how the drop system works in H5.

Let's say the L2J H5 has a group of drops with chance on groups and on each item individual (See bellow)

 

<group chance="4.748700141906738">
	<item id="2384" min="1" max="1" chance="0.2141" /> <!-- Zubei's Leather Shirt -->
	<item id="4066" min="1" max="1" chance="30.2172" /> <!-- Zubei's Leather Shirt Fabric -->
	<item id="2388" min="1" max="1" chance="0.3426" /> <!-- Zubei's Leather Gaiters -->
	<item id="4067" min="1" max="1" chance="45.8801" /> <!-- Zubei's Leather Gaiter Texture -->
	<item id="2390" min="1" max="1" chance="0.1317" /> <!-- Avadon Leather Armor -->
	<item id="4068" min="1" max="1" chance="23.2143" /> <!-- Avadon Leather Armor Lining -->
</group>

So how does it really work? It generate a random Double and check if it access the group. Then it generate a random Double per item and check if it drop OR (which mean it can drop multiple items or it just drop 1 from all group?

 

Thanks in advance. (Appreciate answers only from people with H5 knowledge)

Totallizing all chances you end with exactly 100% so until you were extremely lucky finding the only one totallizing 100%, and assuming it's the same for all groups you don't need to be "H5 knowledge ready" to understand it's one per group.

 

All in one you can simply check existing L2J and compare with L2OFF. L2J tends to "simplify" L2OFF stuff, like precomputed things, to avoid pointless overhead. So if it's different, there's probably a reason.

 

I suppose the min/max is also another random. L2J generally linked it to server rates.

I'm not reading the code of L2J i asked for the official way tryskell. I'm goin to drop their drop system and their enchant system and make new from 0 so i need to know exactly how official work. If official drop 1 from each group then ill do that way. Else if it drop random X per group its a different story. 

 

Regarding OFF im lazy to check thats why i ask which case is the corrent A or B

Thanks.
