Hello and welcome to EsoUI, Motokosworld!
You found the right place for asking this kind of question.
What you want to do can be broken down into four parts:
1, Offer a way to trigger your function
2. Detect when you are at a bank
3. Find all instances of the item in your inventory and move them to the bank
4. Use the 'y' stack function to stack them
I will offer you a basic example that you can use as a starting point.
ad 1)
There are many ways how this can happen.
You can offer a chat command, automatically trigger it whenever the user visits a bank, add a keybind or show some GUI elements that can be clicked.
The first two are comparatively simple while the others require quite some code, so we will stick to a chat command for now.
Lua Code:
SLASH_COMMANDS["/dumpall"] = function()
MyAddon.DumpItemsToBank()
end
ad 2)
This is necessary because you cannot access BAG_BANK unless you are at a banker and chose the bank dialog.
For now we will add a function to prevent DumpItemsToBank from doing anything while we are not at a bank.
Lua Code:
local function IsAtBank()
return GetInteractionType() == INTERACTION_BANK
end
function MyAddon.DumpItemsToBank()
if not IsAtBank() then return end
end
ad 3)
Now we get to the interesting part. First we have to iterate over all our items and test if they are of the type we want to dump.
You mentioned that you want to move all food to bank, so we stick to that for now.
You already found the necessary methods so everything we need to do is combine it like this:
Lua Code:
for slotIndex = 1, GetBagSize(BAG_BACKPACK) do
if GetItemType(BAG_BACKPACK, slotIndex) == ITEMTYPE_FOOD then
MoveItemToBank(slotIndex)
end
end
GetFirstFreeValidSlotForItem seems to work on the same bag only as it requires a slotIndex to specify an item. FindFirstEmptySlotInBag(integer Bag bagId) is more likely to do what we want so we will try it.
We also need to get the stack size in order to move the correct amount. This can be done with GetSlotStackSize(integer bagId, integer slotIndex).
Once we have the slot we can move request to move it there with the function you already have found.
Lua Code:
local function MoveItemToBank(slotIndex)
local stackCount = GetSlotStackSize(BAG_BACKPACK, slotIndex)
local destSlot = FindFirstEmptySlotInBag(BAG_BANK)
CallSecureProtected("RequestMoveItem", BAG_BACKPACK, slotIndex, BAG_BANK, destSlot, stackCount)
end
ad 4)
All that is left now is to find out how the key bind to stack items is working. For this we need to have a look at the UI source code which can be found
here.
The bank is simply another inventory so we take a look at
ingame/inventory/inventory.lua and by looking for the keyword "stack" we find StackBag(BAG_BANK).
So after we put everything together in DumpItemsToBank we arrive at:
Lua Code:
function MyAddon.DumpItemsToBank()
if not IsAtBank() then return end
for slotIndex = 0, GetBagSize(BAG_BACKPACK)-1 do
if GetItemType(BAG_BACKPACK, slotIndex) == ITEMTYPE_FOOD then
MoveItemToBank(slotIndex)
end
end
StackBag(BAG_BANK)
end
This is completely untested so it might not work right away, but it should give you a general idea how it can be done.
EDIT: Just saw that you updated your post. Instead of adding a chat command you can just call MyAddon.DumpItemsToBank() from your event handler too and of course it will be necessary to check if the bank has enough space left before trying to move the item.
EDIT2: corrected code in response to votan
