Namespaces for System Upgrades (with ready-to-go code)

[Rinart73]

A long time ago you introduced "namespaces" - system that allows to have semi-isolated scripts in one Lua VM to reduce memory consumption and increase script to script communication.

But you didn't use this mechanics for system upgrades. And I'm sure they eat a lot of memory, because ship/station can have up to 15 of them.

 

I want to help, so I changed "basesystem.lua" and all vanilla upgrades to utilize system that you used in your "shop.lua".

I'm talking about this:

ScriptNamespace = ShopAPI.CreateNamespace()

Plus I made some changes to make transition more smooth.

 

Which upgrades benefit from this the most:

• Unique systems such as Xsotan upgrades.
  
• Upgrades that don't stack: Wormhole Power Diverter, Minig System, Shield Impenetrator, Smuggler Blocker, Trading Overview, Valuables Detector, Velocity Bypass.
  

Other upgrades will require less memory too for the first one installed.

 

Example (arbitrarytcs.lua):

package.path = package.path .. ";data/scripts/systems/?.lua"
package.path = package.path .. ";data/scripts/lib/?.lua"
local BaseSystem = require ("basesystem")
require ("utility")

-- Don't remove or alter the following comment, it tells the game the namespace this script lives in. If you remove it, the script will break.
-- namespace ArbitraryTcs
ArbitraryTcs = {}
ArbitraryTcs = BaseSystem.CreateNamespace()

-- optimization so that energy requirement doesn't have to be read every frame
ArbitraryTcs.FixedEnergyRequirement = true

function ArbitraryTcs.getNumBonusTurrets(seed, rarity, permanent)
    if permanent then
        return math.max(1, math.floor(rarity.value / 2))
    end

    return 0
end

function ArbitraryTcs.getNumTurrets(seed, rarity, permanent)
    return math.max(1, rarity.value) + ArbitraryTcs.getNumBonusTurrets(seed, rarity, permanent)
end

function ArbitraryTcs.onInstalled(seed, rarity, permanent)
    ArbitraryTcs.addMultiplyableBias(StatsBonuses.ArbitraryTurrets, ArbitraryTcs.getNumTurrets(seed, rarity, permanent))
end

function ArbitraryTcs.onUninstalled(seed, rarity, permanent)
end

function ArbitraryTcs.getName(seed, rarity)
    return "Turret Control System A-TCS-${num}"%_t % {num = ArbitraryTcs.getNumTurrets(seed, rarity, permanent)}
end

function ArbitraryTcs.getIcon(seed, rarity)
    return "data/textures/icons/turret.png"
end

function ArbitraryTcs.getEnergy(seed, rarity, permanent)
    local num = ArbitraryTcs.getNumTurrets(seed, rarity, permanent)
    return num * 350 * 1000 * 1000 / (1.1 ^ rarity.value)
end

function ArbitraryTcs.getPrice(seed, rarity)
    local num = ArbitraryTcs.getNumTurrets(seed, rarity, permanent)
    local price = 7500 * num;
    return price * 2.5 ^ rarity.value
end

function ArbitraryTcs.getTooltipLines(seed, rarity, permanent)
    return
    {
        {ltext = "Armed or Unarmed Turret Slots"%_t, rtext = "+" .. ArbitraryTcs.getNumTurrets(seed, rarity, permanent), icon = "data/textures/icons/turret.png", boosted = permanent}
    },
    {
        {ltext = "Armed or Unarmed Turret Slots"%_t, rtext = "+" .. ArbitraryTcs.getNumBonusTurrets(seed, rarity, true), icon = "data/textures/icons/turret.png"}
    }
end

function ArbitraryTcs.getDescriptionLines(seed, rarity, permanent)
    return
    {
        {ltext = "All-round Turret Control System"%_t, rtext = "", icon = ""},
        {ltext = "Adds slots for armed and unarmed turrets"%_t, rtext = "", icon = ""}
    }
end

 

You can download the archive with all files in the attachments.

It also includes fix for this bug.

I hope that you'll find time to integrate it in the vanilla.
