Due to how some of the internals of KSP works, it's buggy if you don't specify a basemass. I can try to grab basemass from mass in the editor, but sometimes that glitches on the way to the launchpad - specifying it explicitly tends to fix that. Other than basemass, though, you can totally do the rest of that - efficiency, mass, temperature, etc. all default so that if you want, you can just specify a propellant name. Also, note that I am making plugin compatability much easier in future releases; this is my current project: Module Manager

Yeah, just add fuel and oxidizer together. Basemass is generally half the mass of the tank part, which seems to work out to 0.0003125 * volume. Of course, some tanks break this - for example, my configs set the orange tanks as being a little heavier, in exchange for being more efficient at storing LOX and LH2.

Funny you should ask! That's exactly what I've been working on for the past week; if you click on the link, it'll take you to the forum thread where I'm asking for beta testers.

And as soon as 0.20 comes out, we can switch to that system. But in the meantime, I am tired of mucking with part.cfg files

Update: Fixed a NullReferenceException that would only happen if you tried to load a .cfg for a plugin you don't have.

So, let's say you want to install IonCross's Life Support System plugin. And then you want to install FAR's accurate aerodynamics plugin. And then you want to install my wonderful Modular Fuel Tanks plugin. But then you realize: each of these mods requires you to replace your part.cfg files. If you want to install both, you're going to have to go into your part.cfg files, figure out what each mod needs you to change, and then write your own modified version. This is tedious and error-prone, and no for the faint of heart. BUT NOT ANYMORE! Now, IonCross and FAR, and anyone else who distributes modified versions of stock parts, can simply distribute ModuleManager with their own plugin, and ModuleManager will do the work for you. How it works: There's a file that sits in your PluginData directory, called PluginData/ModuleManager/parts.cfg This file looks something like this: include = ModularFuelTanks.cfg include = FAR.cfg include = IonCrossLSS.cfg Then you see that each of those files also exists within PluginData/ModuleManager/; for example, ModularFuelTanks.cfg looks something like this: include = KW_modularFuelTanks.cfg include = BAC9_modularFuelTanks.cfg include = BobCat_modularFuelTanks.cfg fuelTank { REPLACE { RESOURCE { name = LiquidFuel amount = 160 maxAmount = 160 } RESOURCE { name =

amount = 10 maxAmount = 10 } RESOURCE { name = Oxidizer amount = 12.2 maxAmount = 12.2 } } } So, each config file can include multiple subfiles, and can also includes Part nodes. A Part node is simply the name of a Part (for example, fuelTank2-2), followed by a series of subnodes that describe what to change on that part. A Part node can contain any of three types of subnodes: REMOVE A REMOVE node contains a list of fields. Each field's key must be a RESOURCE or MODULE, and its value must be the name of the Resource or PartModule to remove from the part. ADD An ADD node contains a list of nodes. Each node must be a RESOURCE or MODULE node to add to the part. REPLACE A REPLACE node functionally operates like a REMOVE node followed by an ADD node - for each RESOURCE or MODULE subnode, it finds the RESOURCE or MODULE with the name specified, deletes it, and replaces it with the one defined in the subnode. This should make plugin compatibility between authors about 10x easier, while we wait for the official solution in 0.20. Get it here. View source here. What do you think, Sirs?

Nevermind! I got it to work! For everyone who needs to add a PartModule to a part in the VAB, here is how you do it: PartModule module = part.AddModule (addNode.GetValue("name")); if(Awaken (module)) { // uses reflection to find and call the PartModule.Awake() private method module.Load(addNode); Awaken(module) is a static method that looks like this: public static bool Awaken(PartModule module) { // thanks to Mu and Kine for help with this bit of Dark Magic. // KINEMORTOBESTMORTOLOLOLOL if (module == null) return false; object[] paramList = new object[] { }; MethodInfo awakeMethod = typeof(PartModule).GetMethod("Awake", BindingFlags.Instance | BindingFlags.NonPublic); if (awakeMethod == null) return false; awakeMethod.Invoke(module, paramList); return true; } Because reflection in C# is AWESOME.

I can make the plugin happen.

Sweet... make the shock plate animate over 1.0s and give to me, and I will build a plugin to make it work.

Update: After lots of blind flailing and remembering a bit of a conversation with Mu, I've discovered that the problem is that part.AddModule(ConfigNode node) fails if the partModule's .Awake() method doesn't get called (apparently there's setup that happens in there). Unfortunately, PartModule.Awake() is private. Fortunately, C# has reflection. I've now managed to get new PartModules to successfully spawn from the editor. However, the parts they spawn on still do not appear to recognize their PartModules. What is the order of operations necessary to add a new module to a part at runtime, from outside that part's scope?

Heh, my bad... teach me to copy/paste from multiple files. The "3600" should read "360".

Update: I've since fixed this ship so it doesn't arbitrarily knock off Aerospikes; if I can, I'll post a .craft file later.

No, the code is right as-is. Useable volume is what the player inputs, because that's what the player cares about. "Consumed volume" is equal to useable volume PLUS the inefficiency, which is equal to 1/efficiency. As a user, you just enter "5500" in the LiquidH2 box, and it sets your LiquidH2 to 5500. If that takes up 6200 volume units, then 6200 volume units need to be subtracted from the tank - but as the user, you shouldn't have to do that math. You shouldn't have to say "if I want to store X units of this resource, how much should I ask for?" - you just pick your tank internal volume, and my system computes the rest.

I'll release to spaceport once I have enough evidence that there aren't any hidden bugs, but in the meantime: Ialdabaoth's Modular Fuel Tank system source at: https://github.com/Ialdabaoth/modularFuelTanks Released through GPL3.0 (http://www.gnu.org/licenses/gpl.html) HOW IT WORKS: 1. First, you need a part configured with a ModuleFuelTanks. The simplest ModuleFuelTanks node you can have looks something like this: MODULE { name = ModuleFuelTanks volume = 400 TANK { name = LiquidFuel } TANK { name = Oxidizer } TANK { name = MonoPropellant } } This tells my plugin that you have a fuel tank with a total volume of 400 Kerbos (note: one Kerbo = 6.25 Liters; talk to Squad), and you want the user to be able to fill that tank with any amount of MonoPropellant, Oxidizer and LiquidFuel, so long as the total volume of those 3 propellants adds up to less than 400. If you want to get fancier, here is a more complicated MODULE: MODULE { name = ModuleFuelTanks volume = 400 basemass = 0.125 TANK { name = LiquidH2 loss_rate = 0.000015 efficiency = 0.975 mass = 0.000 } TANK { name = LiquidOxygen efficiency = 0.995 mass = 0.0003125 loss_rate = 0.0000025 } TANK { name = LiquidFuel efficiency = 1.0 mass = 0.0003125 } TANK { name = Oxidizer efficiency = 1.0 mass = 0.0003125 } TANK { name = MonoPropellant efficiency = 1.0 mass = 0.0005 } } This tells the module that this tank can hold LiquidFuel, Oxidizer, MonoPropellant, LiquidH2 and LiquidOxygen. It also tells the module how much additional mass or volume each type of tank consumes (beyond the mass and volume of the fuel itself), and that LiquidHydrogen is slightly leaky. The values are: name = LiquidOxygen // the RESOURCE name that this kind of tank holds efficiency = 0.995 // the percentage of tank volume that can store fuel mass = 0.0003125 // the additional dry mass added per volume of this tank temperature = -183 // the temperature that fuel begins evaporating loss_rate = 0.0000000002 // the rate at which fuel evaporates of the container. Note that 'mass' and 'efficiency' is per volume of fuel, not per volume of tank+fuel. So if you want a tank to store 360 units of LiquidOxygen, in the RESOURCES column say: RESOURCE { name = LiquidOxygen amount = 360 maxAmount = 360 } Assuming the TANK configuration above, MaxAmount = 360 will create a tank that takes up (360 / .995) = 361.809 of the available volume, and which adds 360*.0003125 = 0.1125 tons to the dry mass of the tank, in addition to the mass of the LiquidOxygen itself. As long as the tank's Part is at a temperature below -183 Celsius, no LiquidOxygen will leak out; otherwise, LiquidOxygen will begin leaking out at a rate of (360*0.0000000001) = 0.000000036 units per second per degree Celcius that the part's temperature exceeds -183. At room temperature (25C), this works out to about 0.027 units per hour. 2. Once you have the module specified correctly in part.cfg, you can load up the tank in the editor. After attaching it to your ship, go to the Action Groups menu and click on the tank. There you will see various options - each fuel type will have a button to add a tank, or text boxes to adjust the tank volume and initial amount of that fuel, as well as a button to remove all tanks from this part. When you edit a If the system detects an engine attached, it will (usually) also give you a button to remove all tanks and then fill the entire volume with that engine's fuel, in the ratio that that engine consumes it. When you edit a fuel tank, its load out is automatically copied to all identical symmetrical fuel tanks. If you want to have an asymmetrical load-out, attach each tank separately with symmetry off, then edit each tank individually. 3. You can also configure engines to use multiple fuel types, like so: MODULE { name = ModuleEngineConfigs configuration = LiquidFuel+Oxidizer (50 Thrust, 370 Isp) modded = false CONFIG { name = LiquidFuel+Oxidizer (50 Thrust, 370 Isp) thrustVectorTransformName = thrustTransform exhaustDamage = True ignitionThreshold = 0.1 minThrust = 0 maxThrust = 50 heatProduction = 300 fxOffset = 0, 0, 0.21 PROPELLANT { name = LiquidFuel ratio = 0.4 DrawGauge = True } PROPELLANT { name = Oxidizer ratio = 0.6 } atmosphereCurve { key = 0 370 key = 1 270 } } CONFIG { name = LiquidFuel+LiquidOxygen (55 Thrust, 390 Isp) thrustVectorTransformName = thrustTransform exhaustDamage = True ignitionThreshold = 0.1 minThrust = 0 maxThrust = 55 heatProduction = 275 fxOffset = 0, 0, 0.21 PROPELLANT { name = LiquidFuel ratio = 0.35 DrawGauge = True } PROPELLANT { name = LiquidOxygen ratio = 0.65 } atmosphereCurve { key = 0 390 key = 1 300 } } CONFIG { name = LiquidH2+LiquidOxygen (40 Thrust, 460 Isp) thrustVectorTransformName = thrustTransform exhaustDamage = True ignitionThreshold = 0.1 minThrust = 0 maxThrust = 40 heatProduction = 250 fxOffset = 0, 0, 0.21 PROPELLANT { name = LiquidH2 ratio = 0.73 DrawGauge = True } PROPELLANT { name = LiquidOxygen ratio = 0.27 } atmosphereCurve { key = 0 460 key = 1 310 } } } Each CONFIG node is effectively a ModuleEngines MODULE node that will overwrite the part's original ModuleEngines node when selected in the editor. Note that configuration=<name> MUST point to a CONFIG which matches the default ModuleEngines node. [https://github.com/Ialdabaoth/ModuleManager/blob/master/ModuleManager.zip?raw=true]Download link from GitHub This .ZIP contains the ModularFuelTanks plugin, the ModuleManager plugin, and ModuleManager .cfg files for each of the stock engines and fuel tanks in the game, as well as KW tanks and KSPX tanks, and courtesy ModuleManager .cfg files for Ferram Aerospace Research, RemoteTech, and IonCrossLSS. It also contains Resource definition .CFG files to give you a more "realistic" selection of fuels: -LiquidFuel is now changed to have the density and performance stats of kerosene (RP-1) -Oxidizer now has the density and performance stats of N2O4 -LiquidOxygen is added as an alternate oxidizer, which gives slightly better thrust and Isp at the cost of requiring cryogenic storage. -LiquidH2 is added as an alternate fuel, which gives lower thrust but higher Isp, and which is required for the LV-N nuclear rocket. Source code is here, if you're into that sort of thing.

There are some fungi with up to 8 different sexes, where each sex can reproduce with any of the other 7 (but not itself). I'll look up the specifics and come back...

So yeah. I'm trying to dynamically add PartModules to a part in the VAB editor. When I call part.AddModule(ConfigNode node) with a known good ConfigNode (it's an EngineModule from another engine), PartModule.Load(node) causes a NullReferenceException. What am I doing wrong?

Same problem - you now have a list that isn't attached to anything.

Start a new solution, make it a library, import the Unity and KSP assemblies.

Tried it. referencing the part and partmodule's GameObject doesn't work, because the editor-part isn't at all the same part as the launchpad-part. The ship gets rebuilt from a temporary save file on the launchpad, so all you'd succeed in doing with DontDestroyOnLoad is having parts floating somewhere that never get cleaned up, leading to a memory leak.

Somehow, ModuleEngines manages to create a List<Propellants> that gets loaded from the part.cfg file, and this List<Propellants> is successfully copied from the part in VAB's PartLoader.LoadedPartsList into the part that gets created to stick on your ship in the editor. I cannot replicate this behavior in my own modules. I've done everything Mu presented in this thread, but when I click on my part and add it to the ship, my List<FuelTanks> is empty. I have confirmed that my List<FuelTanks> in PartLoader.LoadedPartsList has multiple entries, but none of them get copied to the new part. I have also confirmed that ModuleEngines' List<Propellants> DOES get copied correctly in the editor, so clearly what I want to do is possible. Help?

Since this thread is now in the correct forum, I'll go ahead and reply to it and get discussion started again. I had a solution to the following, but it was bugged, so I'm scrapping it and starting over. Knowing how "official" modules handle this would be ideal. 1. How do modules like moduleEngines currently store/retrieve List<>s like moduleEngines' Propellants? Clearly it works for these modules, so I'd like to know how it's being done. 2. Secondarily, if I change a part's Resources in the editor, how do I get those changes to propagate to the version that spawns on the launchpad? Here's my code, if it helps: modularFuelTanks.cs

Yeah. So, Let's say I have a plugin that scans the parts list, and lets you replace dynamically LiquidFuel, Oxidizer, Monopropellant, or any other pumpable fluid. Basically, it lets you reconfigure the fuel tank load of any fuel tank to carry an equivalent volume of any combination of fluids that you want. The trouble is, when I reach the launchpad, any resources that I've deleted from the part stay deleted, but any resources that I've added from the part go away. The resources are absolutely in the part in the VAB, but as soon as the scene changes it all disappears. Any idea what's going on here?

You saw what I'm trying to do, right? I need to get which part/part group is selected, so I can give the user buttons to add modules or change its fuel load.

Update: Making good progress, but I'm discovering an annoying bug. EditorLogic.fetch.PartSelected doesn't seem to work when you're in the Action Groups menu. Any ideas?

That was helpful for about 90% of what I need. The remaining 10% might be more difficult. Here's what I want to do right now:
