Assassin Star withdrawer

Could someone share with me a lua for withdrawing assassin stars from depot ?
Can I use it on trail aswell ?
Thanks

@Kaguya

lua code:

local AmmoUse = "Assassin Star"

local AmmoMax = 200

local AmmoBp = "Purple Backpack"

----------------------



registerEventListener(WALKER_SELECTLABEL, "onWalkerSelectLabel")

function onWalkerSelectLabel(labelName)

if (labelName == "WithdrawAmmo") then

Self.ItemCount(Item.GetID(AmmoUse) < AmmoMax)

AmmoToWithdraw = (AmmoMax - Self.ItemCount(AmmoUse))

Self.WithdrawItems(0, {Item.GetID(AmmoUse), AmmoBp, AmmoToWithdraw}) -- 0, Is the spot of bp on Depot.

end

Thanks man
