How to decode @export_flags value?

Every checkbox store a number - 1, 2, 4, 8, 16, 32 ...
For example if 2, 3, 5 checkboxes are selected the sum will be 2 + 4 + 16 = 22

Why it's made so hard and how to decode number 22, to get array of selected checkboxes - [2, 3, 5]

@export_flags("self", "ally", "enemy") var target = 0

It's a kind of a mask.

The idea is likely that the sums always a unique value that clearly indicates which toggles are well, toggled on. That is only one unique combination can result in that 22 of yours.

It's a bitmask, this is pretty common when using a list of values that can be multiply selected.

For example, you can easy check that the first 2 options are selected by seeing if the value is 3. Well with bitmasks it would be an binary AND operation. So your_option & 0x11 == 0x11 with means the value is true if it is 3 (11 in binary).

You could probably utilize a match statement to do something respective to each plausible mask value.
