This function performs a bitwise AND-conjunction on two or more (unsigned) 32-bit integers. See Bitwise operation for more details.

Syntax

uint bitAnd ( uint var1, uint var2, ... )

Required arguments

  • varN: The value you want to perform an AND-conjunction on

Returns

Returns the conjuncted value.

Example

local flags = 0x23 -- binary: 100011b
local mask = 0x20  -- binary: 100000b

-- Check if bit 1 is set
if bitAnd(flags, mask) ~= 0 then
    outputDebugString("Yeah. It's set")
else
    outputDebugString("I'm sorry ;(")
end

To test if a flag is set or not it's easier using bitTest.
