world/client/0x0102: Monstrosity data

[sruon]

Opted to make an issue so you can double check on your end before including the information

struct mon_flags0_t
{
    uint8_t SpeciesFlag       : 1;  // 0x01
    uint8_t unknown_0_1    : 1;  // 0x02 (unused)
    uint8_t InstinctFlag        : 1;  // 0x04
    uint8_t Descriptor1Flag : 1;  // 0x08
    uint8_t Descriptor2Flag : 1;  // 0x10
    uint8_t unknown_1_1     : 1; // 0x20 (unused)
    uint8_t unknown_1_2     : 1; // 0x40 (unused)
    uint8_t unknown_1_3     : 1; // 0x80 (unused)
};

struct mon_data_t
{
    uint8_t           unknown00[6];       // 0x04-0x09
    mon_flags0_t Flags0;                   // 0x0A
    uint8_t           unknown01;          // 0x0B
    uint16_t         SpeciesIndex;        // 0x0C-0x0D
    uint16_t         unknown02;          // 0x0E-0x0F
    uint16_t         Slots[12];               // 0x10-0x27
    uint8_t           Descriptor1Index; // 0x28
    uint8_t           Descriptor2Index; // 0x29
    uint8_t           unused00[122];    // 0x2A onwards
};

Names are made-up but follow naming conventions I've seen in this repository.

mon_flags0_t

As far as I can tell, only one flag can be set at a time

• SpeciesFlag set when player is changing species
• InstinctFlag set when player is equipping or unequipping Instincts
• Descriptor1Flag set when player changing name prefix in "Descriptor 1" menu
• Descriptor2Flag set when player changing name prefix in "Descriptor 2" menu

SpeciesFlag set

SpeciesIndex will contain the ID of the Monstrosity species the player is changing to, a value that ranges from 1 to 511 (values above 256 are variants of base species)

InstinctFlag set

Slots will contain 12 entries, either set to 0 when the player is not modifying that slot, 65535 when the player is unequipping, or the actual Instinct ID when equipping. Known instinct IDs are between 3 and 799.

Descriptor1Flag / Descriptor2Flag set

Descriptor1Index will be either 0, indicating the player is disabling the display of a descriptor, or a value between 1 and 248 (that's likely in the DATs but I don't have POLUtils installed right now)
