Debugging Utilities

memhack provides debugging utilities for memory inspection and hex conversion. These functions are useful for reverse engineering, verifying struct layouts, and troubleshooting memory related issues.

Hex Conversion

hexToInt

• int memhack.debug.hexToInt(hexstr)

Argument name	Type	Description
hexstr	string	Hex string to convert (supports "0x1A" or "1A" format)

Converts a hex string to an integer. Supports both "0x" prefixed and plain hex strings.

Example:

local value = memhack.debug.hexToInt("0x1A")  -- Returns 26
local value2 = memhack.debug.hexToInt("1A")   -- Also returns 26

intToHex

• string memhack.debug.intToHex(num)

Argument name	Type	Description
num	int	Integer to convert to hex string

Converts an integer to a hex string with "0x" prefix.

Example:

local hexStr = memhack.debug.intToHex(26)  -- Returns "0x1A"
LOG("Address: " .. memhack.debug.intToHex(pilot:getAddress()))

bytesToHex

• string memhack.debug.bytesToHex(bytes, bytesPerGroup)

Argument name	Type	Description
bytes	string	Binary data string
bytesPerGroup	int	Optional. Number of bytes before space separator (default: 0, space between each byte)

Converts a byte array (binary string) to a hex string representation with optional grouping.

Example:

local bytes = "\x01\x02\x03\x04"
local hex = memhack.debug.bytesToHex(bytes)       -- "01 02 03 04"
local hex2 = memhack.debug.bytesToHex(bytes, 2)   -- "0102 0304"
local hex3 = memhack.debug.bytesToHex(bytes, 4)   -- "01020304"

hexToBytes

• string memhack.debug.hexToBytes(hexStr)

Argument name	Type	Description
hexStr	string	Hex string (spaces and "0x" prefix are automatically stripped)

Converts a hex string to binary data. Handles spaces and "0x" prefix automatically.

Example:

local bytes = memhack.debug.hexToBytes("01020304")      -- 4 bytes
local bytes2 = memhack.debug.hexToBytes("01 02 03 04")  -- Also 4 bytes (spaces ignored)
local bytes3 = memhack.debug.hexToBytes("0x01020304")   -- Also 4 bytes (0x ignored)

Memory Inspection

logFromMemory

• void memhack.debug.logFromMemory(address, numBytes, bytesPerLine, bytesPerGroup)

Argument name	Type	Description
address	int	Memory address to start reading from
numBytes	int	Number of bytes to read
bytesPerLine	int	Optional. Bytes per line (default: 64)
bytesPerGroup	int	Optional. Bytes per group with space separator (default: 4)

Logs a formatted hex dump of memory contents starting at the specified address. This is useful for inspecting raw memory structures and verifying struct layouts.

Example:

local pilot = pawn:GetPilot()
local address = pilot:getAddress()

-- Dump 256 bytes starting at pilot address
memhack.debug.logFromMemory(address, 256)

-- Custom formatting: 32 bytes per line, grouped by 8
memhack.debug.logFromMemory(address, 128, 32, 8)

Output format:

Memory dump from 0x12345678 (256 bytes)
0x12345678: 01020304 05060708 090A0B0C 0D0E0F10 ...
0x12345688: 11121314 15161718 191A1B1C 1D1E1F20 ...
