I figured out how to set the second member in sSlotInfo struct. It’s cumbersome, but you have to set the individual members, int by int, and keep track of the offset for the remaining members. Like so:
local sSlotInfo = DataView.ArrayBuffer(128)
sSlotInfo:SetInt32(0, 0)
sSlotInfo:SetInt32(0, sGuid:GetInt32(0))
sSlotInfo:SetInt32(8, sGuid:GetInt32(8))
sSlotInfo:SetInt32(16, sGuid:GetInt32(16))
sSlotInfo:SetInt32(24, sGuid:GetInt32(24))
sSlotInfo:SetInt32(16, 0)
sSlotInfo:SetInt32(24, 0)
sSlotInfo:SetInt32(32, 0)
I have now ported TuffyTown’s code into Lua and added some code for weapons which, unfortunately, doesn’t work. It’s annoying because the WEAPON_MELEE_LANTERN should added to your inventory so you can equip after switching weapon.
It’s very cool to see food (e.g., CONSUMABLE_PEACHES_CAN) finally in my inventory in RedM, but when I select and use it, nothing happens. It would be very interesting to see if we can hook an event or someway find out how to detect this action and implement it ourselves. Here’s my Lua port:
function NewGuid()
local struct = DataView.ArrayBuffer(8 * 4)
struct:SetInt32(0, 0)
struct:SetInt32(8, 0)
struct:SetInt32(16, 0)
struct:SetInt32(24, 0)
return struct
end
function NewSlotInfo()
local guid = NewGuid()
local struct = DataView.ArrayBuffer(8 * 8)
-- Begin guid memmber
struct:SetInt32(0, guid:GetInt32(0))
struct:SetInt32(8, guid:GetInt32(8))
struct:SetInt32(16, guid:GetInt32(16))
struct:SetInt32(24, guid:GetInt32(24))
-- end guid member
struct:SetInt32(32, 0) -- int f_1;
struct:SetInt32(40, 0) -- int f_2;
struct:SetInt32(48, 0) -- int f_3;
struct:SetInt32(56, 0) -- int slotId
struct.GetGuid = function()
return guid:Buffer()
end
struct.SetGuid = function(newGuid)
struct:SetInt32(0, newGuid:GetInt32(0))
struct:SetInt32(8, newGuid:GetInt32(8))
struct:SetInt32(16, newGuid:GetInt32(16))
struct:SetInt32(24, newGuid:GetInt32(24))
end
return struct
end
function NewItemInfo()
local struct = DataView.ArrayBuffer(8 * 6)
struct:SetInt32(0, 0)
struct:SetInt32(8, 0)
struct:SetInt32(16, 0)
struct:SetInt32(24, 0)
struct:SetInt32(32, 0)
struct:SetInt32(40, 0)
struct:SetInt32(48, 0)
return struct
