TFS 1.X+ Convert Flag value to enum from getSlotPosition()

[Paulix]

Hello, I'm trying to check if an item can be use on slots 1, 4, 7, 8, 12 (Head, Armor, Legs, Feet or Hands)
Enums on src looks like this...

enum slots_t : uint8_t {
    CONST_SLOT_WHEREEVER = 0,
    CONST_SLOT_HEAD = 1,
    CONST_SLOT_NECKLACE = 2,
    CONST_SLOT_BACKPACK = 3,
    CONST_SLOT_ARMOR = 4,
    CONST_SLOT_RIGHT = 5,
    CONST_SLOT_LEFT = 6,
    CONST_SLOT_LEGS = 7,
    CONST_SLOT_FEET = 8,
    CONST_SLOT_RING = 9,
    CONST_SLOT_AMMO = 10,

    CONST_SLOT_FIRST = CONST_SLOT_HEAD,
    CONST_SLOT_LAST = CONST_SLOT_AMMO,
};

but using getSlotPosition(), it is returning the flag value like this

enum SlotPositionBits : uint32_t {
    SLOTP_WHEREEVER = 0xFFFFFFFF,
    SLOTP_HEAD = 1 << 0,
    SLOTP_NECKLACE = 1 << 1,
    SLOTP_BACKPACK = 1 << 2,
    SLOTP_ARMOR = 1 << 3,
    SLOTP_RIGHT = 1 << 4,
    SLOTP_LEFT = 1 << 5,
    SLOTP_LEGS = 1 << 6,
    SLOTP_FEET = 1 << 7,
    SLOTP_RING = 1 << 8,
    SLOTP_AMMO = 1 << 9,
    SLOTP_DEPOT = 1 << 10,
    SLOTP_TWO_HAND = 1 << 11,
    SLOTP_HAND = (SLOTP_LEFT | SLOTP_RIGHT)
};

I didn't want to make the numbers manually, like 49, 50, 56 etc...
How can I convert the return from getSlotPosition to and integer to compare with those constants like CONST_SLOT_AMMO?

what are you trying to do? what about using another function like these functions

I'm using nekiro downgrade from 1.5, dont have those functions

 

[Dakos]

struct shouldbe the same no? just add these funcs manualy

Isn't there a way to convert flags to int? it would be much easier than having to compile again

yes, it does.

but you can use it, if you want..

local slotBits = {
    [CONST_SLOT_HEAD] = SLOTP_HEAD,
    [CONST_SLOT_NECKLACE] = SLOTP_NECKLACE,
    [CONST_SLOT_BACKPACK] = SLOTP_BACKPACK,
    [CONST_SLOT_ARMOR] = SLOTP_ARMOR,
    [CONST_SLOT_RIGHT] = SLOTP_RIGHT,
    [CONST_SLOT_LEFT] = SLOTP_LEFT,
    [CONST_SLOT_LEGS] = SLOTP_LEGS,
    [CONST_SLOT_FEET] = SLOTP_FEET,
    [CONST_SLOT_RING] = SLOTP_RING,
    [CONST_SLOT_AMMO] = SLOTP_AMMO
}

local function getSlot(id)
  local it = ItemType(id)
  if it then
    local slotPos = it:getSlotPosition()
    for slot, value in pairs(slotBits) do
      if bit.band(slotPos, value) ~= 0 then
        return slot
      end
    end
  end
  -- return nil if not found?
end
