Description
- Description:
- Checks if one or more flags are set in the given flagset, represented with decimal or hexadecimal number
(Hexadecimal number representation is simply auto-converted into decimal by the engine)
In other words, it simply performs a bitwise AND (&) operation on the two numbers: flags & flagset > 0
To check which flags are present in given flagset use BIS_fnc_bitflagsToArray - Execution:
- call
- Problems:
- Due to various limitations of the Real Virtuality engine this function is intended to work with unsigned 24 bit integers only. This means that the supported range is 2^0...2^24 (1..16777216).
- Groups:
- Bitwise
Syntax
- Syntax:
- [flagset, flag] call BIS_fnc_bitflagsCheck
- Parameters:
- flagset: Number - flagset
- flag: Number - one or more flags to check
- Return Value:
- Boolean
Examples
- Example 1:
