==== Decoding accessory data ====

Revision as of 01:23, 2 April 2011

Accessories can be found in the 1900-2000s range of the ID table. There appear to be less than 256 accessories in-game, and the accessory data does in fact code the accessory items as 8-bit values.

There does not appear to be a relationship between the 8-bit accessory item value and that accessory's PlaceTag ID.

Another detail that apparently is encoded is the accessory color. Various cards have scanned with green, orange, and white disco wigs. It's uncertain if the color details are separate from the accessory value, or if there are different accessory values for different colors.

The size of the accessory count field (3 bits) caps the number of encoded accessories to 7, although the most number of accessories seen encoded on a card so far has been 6.

Accessory flag

An accessory flag indicates the optional presence of accessory data further within the data. The accessory data starts off with an accessory count, indicating a variable number of 8-bit accessory item values follow:

Accessory flag ... Count Item 1 Item 2 ...
1 ... 2 76 123 ...

Location of accessory flag

All of the Vision_Single Blackariant, GoodVariant, and PlaceTag cards have the accessory flag at offset 29. The Banjo-Kazooie theme cards also appear to have their accessory flag at the same offset.

Accessory data

The optional accessory data is variable length, starting off with an accessory count, followed by that number of 8-bit accessory item values.

Location of accessory data

The accessory data appears to closely follow the accessory flag, with an apparent relative offset of 6 bits. The optional accessory data does offset further trailing data, such as the use cost and name flags.

1This likely subtype field often has a value of 1110 for most accessoried pinatas (compared to 1011 for non-accessoried pinatas), although the accessoried and named theme cards (e.g., Banjo, Killer Instinct, Halo) have a subtype of 0000 (and possibly use a different offset for their accessory data).

2The accessory flag. When set, optional accessory fields (shown in blue and marked as 3 to 6) follow.

3It's not certain if this unknown field preceeds the accessory data, or starts the accessory data. Its value is often 00000.

4The accessory count field. Indicates the number of 8-bit accessory item values that follow.

5The accessory item field(s).

6It's not certain if this unknown field trails the accessory data, or ends the accessory data. Its value is often 1011 or 0011.

7 The continuation of the flag bits. (If the optional accessory data was not present, these bits would immediately follow the accessory flag.) In this example, the use cost flag is set (and the name flag is clear).

8This unknown field preceeds the variant data. Its value always appears to be 01010.

Decoding accessory data

PlaceTag cards do appear to have an accessory count field in row 1. This field appears to exist even if the item placed isn't a species. (That's reasonable, since there appears to be a single format for PlaceTag cards, independent of what type of item is on the card. I.e., we can turn a PlaceTag_Home card into a species just by changing the ID.)

An easy way to spot accessoried pinatas at VivaPinata.com is to check how many barcode rows are on the card. A player-created card with 3 rows definitely has 5 or more accessories. A player-created non-wildcard non-variant card with 2 rows definitely has accessories. (A normal pinata without accessories has a 1 row barcode.)

Sample of cards with accessories

This is an incomplete list of cards where scanned pinatas are wearing accessories. Most of the cards are official versions released by Rare before the launch of Trouble in Paradise. (Recognized by a SpeciesPV name, and a picture of 3 accessories on the front of the card.) A few of the cards are date-locked, while the remaining cards are player-created from VivaPinata.com.

In addition to having accessories, pinatas may be variants and/or wildcards, or even have pinata names (Rare-only) encoded in the data.

The order of the accessories must exactly match the Journal accessories list, seen when viewing the scanned pinata's information. (Likewise, the variant numbering is from the Journal, not the wiki.)

The more accurate data we can collect for cards from the same obfuscation set, the more likely we can decode the underlying accessory data, and start to read accessory details from future/other cards.
