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.
