TFS 0.X How to Block Clicking Backpack on House Door?

[willks123]

My server is X 2 - 0.7 - Version 7.72

I have a House Protection script, but if the player puts a Backpack on the Door to Make Runes, anyone can open the Backpack and take what's inside.

How do I make it so that only those who are invited to the house can click on backpacks or move items inside the house?

My houseprotection.lua:

local function isInvited(houseId, playerName)
    if(string.find(string.lower(getHouseAccessList(houseId, 0x100)), playerName) or string.find(string.lower(getHouseAccessList(houseId, 0x101)), playerName)) then
        return true
    end

    return false
end

function onMoveItem(moveItem, frompos, position, cid)
    if((getPlayerGroupId(cid) < 6) and (getTileInfo(position).house) and (getHouseOwner(getHouseFromPos(position)) ~= getPlayerGUID(cid)) and (not isInvited(getHouseFromPos(position), string.lower(getCreatureName(cid))))) then
        doPlayerSendCancel(cid, "You cannot throw there.")
    else
        return true
    end
end
