Adding / Removing items from Cash Shop

[imNotFlav]

You'll have to decode the entire long CS packet first. [It is after the 15 x 4 bytes of teleport rock data]
The first few bytes should be what you'r telling the client to sell on the "sale" or "wanted" list.

Credits go to this smexy guy for pointing it out to me.


In your warpToCS packet there's 1 int after the account name which I'm not sure what it is for. And after that there's a short for the number of modified items. For each modified item you do this:

            mplew.writeInt(sn);
            mplew.writeInt(0x400);
            mplew.write(0);

The 0x400 is a modifier which means that we remove or add an item, the following byte tells the client what we do (0 = remove, 1 = add). There are a couple of other modifiers which I'm not so sure about what they do and how exactly they work, I know that there's one for price discounts and for limitations. Whatever, we find most Cash Items multiple times in Etc.wz/Commodity.img with different prices, so we don't really need the other modifiers.
Anyways, to add or remove items just store them into a List and then use it in your warpToCS packet. Here's a spoonfeed example for leechers:

        mplew.writeMapleAsciiString(c.getAccountName());
        mplew.writeInt(0);
        mplew.writeShort(CashDataProvider.getModifiedData().size());

        for (int sn : CashDataProvider.getModifiedData()) {
            mplew.writeInt(sn);
            mplew.writeInt(0x400);
            mplew.write(CashDataProvider.getItem(sn).isOnSale() ? 1 : 0);
        }

If you're smart and have an onSale check don't forget to change it for modified items. I'll probably include this in OdinTeh 2 soon where I already have added lots of Cash Shop stuff, then you can leech it out of there.

There's another way to do this, simply modify your Etc.wz file and make your users download it but that's gay.

I don't really like this forum but I know that if I don't release it here someone will leak it.

Good release Flav.

Well i don't get it much i know the code but how to like add it u gotta add the id or the code
(gah coding == confusion)
HAII FLAV DDD

Here's an example for adding it directly into the packet, however, I suggest you to use a List and read it from database:

        mplew.writeMapleAsciiString(c.getAccountName());
        mplew.writeInt(0);
        mplew.writeShort(1); // number of modified items

        mplew.writeInt(10001484); // serial number for Veamoth Package
        mplew.writeInt(0x400); // modifier
        mplew.write(1); // add

Good job Flav.
Maybe I'll use this in MapleLite.

If I can get rid of my damn d/c at char select.

HOLY @#$% FLAV U SOOO SMARTTT AND SO AS lIGHTpEPSI

Two things:
1)Can't you make it editable in sql ,like add the item u want in mysql and it reads it and shows the items in cashshop?

2)Can you add non-nx items in it ?

 

[imNotFlav]

1) That's exactly what I suggested you to do.
2) No, you add items by their serial numbers which only Cash Items have.

wow nice release. Very usefull

 

[iAkira]

Thanks flav u so smart Hope this ends up in odinteh2 =PP

 

[Zeillinger]

Another stupid wz edit avoided :3
Great release.

        mplew.writeInt(0);

        mplew.writeInt(10001484); // serial number for Veamoth Package
        mplew.writeInt(0x400); // modifier
        mplew.write(1); // add

Odd, my client crashes with that code. Here's my warpCs packet (which also is the packet to warp to the MTS, but the boolean is still false):

		mplew.writeMapleAsciiString(c.getAccountName());
		if (mts) {
			mplew.writeInt(5000);
			mplew.write(HexTool.getByteArrayFromHexString("0A 00 00 00 64 00 00 00 18 00 00 00 A8 00 00 00 B0 ED 4E 3C FD 68 C9 01"));
		} else {
			mplew.writeInt(0);
			mplew.writeShort(1); // number of modified items

			mplew.writeInt(10001484); // serial number for Veamoth Package
			mplew.writeInt(0x400); // modifier
			mplew.write(1); // add
		}

This is for v62 if that makes any difference.

It's possible that the packet is different. Try to change the int before the short that tells you the number of modified items to short as well, maybe NEXON added something in v0.63+.

 

[dman765]

Nice i needed this for my new Max Stat items System For NX Clothes

 

[nugyyman]

        mplew.writeInt(0x400); // modifier

Is this simillar to every item ?

 

[LightRyuzaki]

nice :]!

Ya, But. How about like a GM Hat? Or custom prices?

No, you add items by their serial numbers which only Cash Items have.

 

[Synthesizer]

This is a great release;
I was wondering how to remove stuff from the CS.

 

[imNotFlav]

Serial numbers can be found in Etc.wz/Commodity.img or in cash_commodity_data if you have MCDB.
