Loot Table Addon/Patch for Yanfly Extra Drops

[CursedEmbrace]

Hello everyone, today I have a script request I'm hoping someone or several some ones can help with.

I use the Yanfly extra drops script which is great for all those random little incidental items I'd like enemies to drop but it doesn't quite do all I'd like when it comes to bosses.

What I'd like is to be able to create a new kind of note that creates a "table" of items with its own drop rate. Lets say, for the sake of example I have a "table" that has a 50% chance of dropping from a boss and in that table I have three items, each one has a 33.333 ect% chance (or whatever values I input into the notes) of being selected as the single drop from the "loot table".

I hope that makes sense.

Anyway, what I hope to achieve from this is a situation similar to games such as World of Warcraft where bosses can have randomly assigned loot but still guarantee a certain number of dropped items.

I envision a bosses notes perhaps looking something like:

<drop I12: 20%>
<drop I13: 5%>
<drop I14: 2%>
<droptable: 100%: I44:25%, W12:25%, A7:25%, A13:25%>

Or something like that, which allows for both random little items (potions and the like perhaps? Maybe crafting materials?) while the table, of which there can be multiples of even the same table to assure that some of the better loot is gotten by the party while keeping the random nature of rpg loot.

I'll provide the copy of the Yanfly extra loot script that I'm using, as that will no doubt be helpful.

I think that's all for now, thanks for reading and I hope you're all having a good day.

Couldn't you just use a script which makes random items pop up from items on usage?


I would certainly make it that way.


You can name it "Treasure Box" or however you want it, give it 100% drop rate from bosses, and when the player opens it, a random item will be gained.


Several scripts like this exist, I know Dekita made one, that is what I use in my project and it works perfectly!

That certainly is an option I could resort to if needed, but the loot table thing would be a bit more elegant (seeing the stuff you get directly on the victory aftermath screen and so on, saving item slots in the database ect.), although an amount of work (possibly a lot of work) for whoever makes it. Its a reasonable idea though, so thanks.

Actually, I remember seeing a script like what you described.


Ever played Dragon Nest? At the end of a dungeon, the player could choose a treasure chest from 4 chests.


The script I am talking about does the exact same thing.


It visually displays 4 (or how many you want) chests, and the player can choose one from them at the end of the battle. It is totally independent from the default drop system.


The sad part is, however, that I forgot where I saw this and have no idea about the author's name.


I guess it was over at rmrk.net somewhere. You could try to search for that one, maybe you will have better luck in finding it than I got. I will keep looking for it later too.


It might need a compatibility patch for Yanfly's Aftermath, but I can make that for you, if you can find the script I mentioned.

 

[CursedEmbrace]

Do you perhaps mean this one? http://www.rpgmakervxace.net/topic/22905-treasure-chests/

Other than that the script looks nice, though I'd prefer if the player could choose more than one chest if I was going to go with this.

I was toying around with the idea of loot tables myself for my own projects, though I haven't found an intuitive way to implement them... Anyways, I'll spend some more time with it the next couple of days and let you know what I come up with.

Oh, thanks for looking into it.

--Edit

My partner (who has only recently been learning how to code for rpgmaker) took a look at the Yanfly drop script and came up with an edit that has actually more or less put together what I was looking for (as far as we know!) thought I'd post the edited version of the script to that you veterans might be able to improve on it or something, I don't know.

How would a person utilize this script for chests on a map,

and is it compatible with RMMV or is it strictly Ace?

Cause I would like to be able to have a chest that the character opens, and gives a random items with % to loot each item.
Difference here is not looting  monster during battle so afraid enemy.extra drops wouldn't work. Additionally I want chest to

only be opened x times per day ( day being game time. )
