type Flag 

type Flag []uint32

Flag is a bitset stored as 32-bit words (most significant bits at lower indices).

func NewFlag 

func NewFlag() *Flag

NewFlag returns a flag with Default bits (64).

func NewFlagBits 

func NewFlagBits(uBits int) *Flag

NewFlagBits constructs a Flag with exactly uBits capacity.

func (*Flag) Data 

func (f *Flag) Data() []uint32

Data returns the internal data slice (do not modify).

func (*Flag) IsZero 

func (f *Flag) IsZero() bool

IsZero reports whether all bits are zero (or the flag has no words).

func (*Flag) SetBitNumber 

func (f *Flag) SetBitNumber(uBit int, uValue int)

SetBitNumber sets a specific bit to 0 or 1. Bits are addressed MSB-first per 32-bit word.

func (*Flag) SetValue 

func (f *Flag) SetValue(uValue uint32)

SetValue assigns a scalar 32-bit value to the least significant word, zeroing all higher words (mirrors Java).

func (*Flag) ToByteArray 

func (f *Flag) ToByteArray(bNewVer bool) []byte

ToByteArray returns the byte representation identical to the Java code. If bNewVer is false, it writes bytes in a "reverse fill" big-endian order across the entire array (matching Java's decrementing uLen fill). If bNewVer is true, it writes each 32-bit word in little-endian order, from last word to first.

func (*Flag) ToByteArrayEx 

func (f *Flag) ToByteArrayEx() []byte

ToByteArrayEx is the "reverse" of ToByteArray: it outputs per-word little-endian bytes, iterating from the end towards the beginning.

type Item 

type Item struct {
	ID int32
	// contains filtered or unexported fields
}

func CreateItemFromID 

func CreateItemFromID(id int32, amount int16) (Item, error)
