BIS_fnc_bitflagsCheck

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

Syntax

[flagset, flag] call BIS_fnc_bitflagsCheck

Parameters:

• flagset: Number - flagset
• flag: Number - one or more flags to check

Returns: Boolean

• true: one or more flags are set in given flagset
• false: no given flag or flags are set in the given flagset

Examples

Example 1

[2 + 4 + 8, 8] call BIS_fnc_bitflagsCheck; // true
[2 + 4 + 8, 2 + 32] call BIS_fnc_bitflagsCheck; // true
[2 + 4 + 8, 1] call BIS_fnc_bitflagsCheck; // false
[2 + 4 + 8, 1 + 32] call BIS_fnc_bitflagsCheck; // false

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).
