Lua:bNot

function bNot(int1) : Integer

Performs a bitwise NOT operation on the given integer. This function inverts all bits of the input value, changing 1s to 0s and 0s to 1s. It behaves the same as Lua's bitwise NOT operator (~) in Cheat Engine.

Function Parameters

Parameter	Type	Description
int1	integer	The value whose bits will be inverted.

Returns

An integer representing the bitwise NOT of the input.

Description

Bitwise NOT flips every bit in the input integer. For example, in an 8-bit context, 0x0F (00001111) becomes 0xF0 (11110000).

Binary example (8-bit representation):

00001111   (0x0F)
--------
11110000   (0xF0)

Common uses include:

• Inverting masks
• Clearing specific bits using combination with AND
• Logical bit manipulation

Usage Examples

Simple bitwise NOT:

print( bNot(0x0F) )   -- 0xF0 (in 8-bit context)

Using Lua's NOT operator (equivalent):

print( ~0x0F )         -- 0xF0 (in 8-bit context)

Clearing specific bits using NOT and AND:

local value = 0xFF
local mask  = 0x0F
local cleared = bAnd(value, bNot(mask))  -- clears lower 4 bits
print(string.format("0x%X", cleared))  -- 0xF0

Behavior

• Returns an integer.
• Only works on numeric values.
• Equivalent to Lua's bitwise NOT operator (~) in Cheat Engine.
• Useful for bitmask manipulation and logical inversions.

Advanced Examples

Inverting multiple flags:

local flags = 0x0D   -- 1101
local inverted = bNot(flags)  -- 0010 (if 4-bit context)
print(string.format("0x%X", inverted))
