[LUA : Show crate capacity]

A little script I knocked up to show the capacity of attached crates.  There are 2 parameters to set, the name of the resource you are monitoring in the crates, and a unit mass(KG/L).  You will need a screen attached called "Screen", or change the relevant part in the script.  Containers don't need a specific name.

 

This is my first time coding LUA, or in DU, so any improvements I can make, please let me know.

 

objectMassPerLitre = 2.7 --export
containerContentsName = "Aluminium" --export

local containerArray = {}
local containerCount = 0

for key, value in pairs(unit) do
     if type(value) == "table" and type(value.export) == "table" then
        if value.getSelfMass then
            containerCount = containerCount + 1
            containerArray[containerCount] = value
        end
    end
end

local containerMassContentsCount = 0
local totalVolume = 0

for i= 1, containerCount do
     containerMassContentsCount = containerMassContentsCount + containerArray[i].getItemsMass()

    if containerArray[i].getSelfMass() == 1281.31 then
        totalVolume = totalVolume + 8000
    elseif containerArray[i].getSelfMass() == 229.09 then
        totalVolume = totalVolume + 1000
    elseif containerArray[i].getSelfMass() == 7421.35 then
        totalVolume = totalVolume + 64000
    elseif containerArray[i].getSelfMass() == 14842.7 then
        totalVolume = totalVolume + 128000
    end
end


local totalContentsVolume = math.floor(containerMassContentsCount / objectMassPerLitre)

local message = containerCount .." containers of ".. containerContentsName .. " <br> " .. totalContentsVolume .."<emp>L</emp> used of ".. totalVolume .. "<emp>L</emp> total space"

if oreDisplay == nil then
    oreDisplay = Screen.addContent(2,50,message)
else
    Screen.resetContent(oreDisplay, message)
end
