Overview

Encoded data are packed bits of information, such as a piñata's name, its variant color, or the cost to use (scan) the card.

Some of this data is optional. For example, cards that are freely reusable do not have a use cost encoded on the card. Likewise, piñatas that aren't named do not have an encoded name on the card.

Other data only exists on certain types of cards. For example, a date-locked card would have date data. Likewise, a card which wasn't date-locked would not have an encoded date at all.

Organization of encoded data

If a card can contain all different kinds of data (some optional, some not), how does the game recognize what specific type of information is encoded on a particular card?

It does this by encoding the type of data (referred to as the payload type), in addition to the data itself. For example, this illustration shows a card with three types of information -- ID, name, and use cost -- each followed by a value for that particular payload type:

ID

Cluckles

Name

Claudia

Use cost

500

Each card, regardless of how little (or how much) is encoded on that card, uses that same payload type:data payload type:data format. The game can easily identify each piece of information on the card, first by examining the payload type (to learn what type of data follows), then processing the payload (the actual encoded data).

Precedence of payload types

Beyond the Start of data and End of data information, it's unknown if the remaining order matters or not.

The general order (for PlaceTag) cards seem to be:

• Start of data
• ID
• Accessory (optional)
• Start date (optional)
• End date (optional)
• Reuse (optional)
• Name or cost (optional)
• Wildcard (optional)
• Variant (optional)
• End of data

The payload type indicates the type of data that immediately follows.

A card can contain several payload types (such as for a pinata that's both a variant and a wildcard).

The payload type is a 5-bit value.

Payload type	Payload size	Payload	Description
00000	4	0000	End of data. No further encoded data follows. Remaining bits pad the data to a barcode row boundary. Padding is filled with specific bits copied from the encoded data, to help obscure what little data may be encoded within the last row.
		0001	Start of data. This payload marks the start of the encoded data. It's also found later in certain cards, such as date-locked cards. (They drop a special pinata on that date, or a normal pinata if scanned on any other day. E.g., Start of data, Date, Special pinata, Start of data, Normal pinata, End of data.)
00001	12	ID data It can also be found later in accessorized (themed) cards, with each successive ID specifying an accessory. Using the 11101 (Accessory) payload type is preferred to this method, as its data takes less space (and also supports encoding accessory colors).
00010	12	Trick stick reskin ID data (PlaceTag IDs for reskins are from 2207 to 2218.)

The accessory items are normalized 8-bit values which correspond to PlaceTag accessory IDs. (E.g., item 1 is PlaceTag ID 1905, item 2 is 1906, and so on.)

Decoding

• Read a count, then read that number of 12- or 8-bit values that follow to determine what (color) accessories a pinata is wearing.

This optional date data is present if the card is date-locked.

Two sets of dates are encoded -- a start date and an end date -- to provide a date-locked interval when the card will scan as a special pinata. Both sets of dates appear to be required, even if the start date and end date are for the same date.

The card appears to scan with options (e.g., name, accessories, wildcard trait, variant color) if the game date is within the date-locked interval, and without options (i.e., a normal pinata) if the game date is outside the date-locked interval.

Decoding

• Day is encoded as a 5-bit value from 1 to 31.

This data is present if the pinata has an encoded name.

Unlike the accessory data, it does not contain a count (length) preceeding the name characters. The name is null-terminated (NUL).

Decoding

• ?

The game likely auto-capitalizes the name, by capitalizing the first letter of the name and any letter that follows a space (SP) character.

Encoding

• ?

The name character set is 5-bit, with no shift bit to distinguish between upper and lower case.

The use cost holds the cost to scan the card (if the card is not flagged as free to scan).

Decoding

• Use the encoded use cost as the cost to scan the card.

To obtain the use cost, multiply the value by the order of magnitude (power of 10). For example, a use cost value of 18 and a use cost magnitude of 2 would be a use cost of 18 x 10² = 18 x 100 = 1800.

Encoding

• If the card will have a chocolate coin cost per scan, encode the use cost value and magnitude.

There does seem to be some variance on how a use cost of 1000 is encoded. Some cards have it stored as 100 x 10, while others have it encoded as 10 x 100. It's uncertain whether the representations are interchangeable or not, although a particular representation may affect other fields such as a checksum.

Variant

Variant
Optional:	Yes
Parent:	PlaceTag
Offset:	0
Size:	4 bits
See also
?

This optional variant data is present if the pinata is a variant.

The variant identifies the variant color of the pinata being scanned.

Decoding

• Outside of value 15, which is always black, it's not possible to determine whether a value is a specific in-game variant color, or even distinguish between in-game and other variant colors. (E.g., 2 may be a GoodVariants color for one species, but in-game variant color 1 for another species.)

Encoding

• Lookup the value for the color to be encoded onto the card.
  • Known GoodVariants have a variant value between 2 and 10 (but values vary between species).
  • In-game variants have a (non-conflicting) variant value between 2 and 9 (and values also vary between species).
  • Known Blackariants have a variant value of 15.

Variant values for the Quackberry

Description	Color	Encoded value
Sick/ill-looking	Mint green	1
GoodVariants	Orange	2
GoodVariants	Red	3
GoodVariants	Purple	4
GoodVariants	Light blue	5
In-game variant 1	Blue	6
In-game variant 2	Pink	7
In-game variant 3	Orange	8
GoodVariants	Light pink	9
Blackariants	Black	15

• Note that GoodVariants colors and in-game variant colors differ (slightly) so Quackberry variant color 2 is not the same orange as Quackberry variant color 8.

Wildcard

This optional wildcard data is present if the pinata is a wildcard.

The wildcard identifies the trait of the pinata being scanned.

• Known wildcards have a trait value between 1 and 3.
