@TaxiService you can do it using reflection, but can I ask why?  Generally replacing stuff that isn't meant to be replaced leads to trouble.

[sarbian]

And the CommNet itself is already made to be extendable. I don't have the reference with me ATM but most of it is extendable without reflexion, it was made that way.

 

Edit : found it. What you should actually replace to replace the commnet implementation is the CommNetwork, so CommNetNetwork.Instance.commNet = <yourImplentation>;

Yup, it is quite extendable and I succeeded in extending the most of the CommNet. But the CommNetNetwork.Instance is not extendable despite that CommNetNetwork has virtual methods to override.

The reason I want to replace CommNetNetwork is that CommNetNetwork contains these codes

The virtual in there are most likely left over from a code iteration. The whole thing is a singleton and a MonoBehaviour and that bring plenty of ways for things to go sideway if you try to replace it...

Indeed there is something bad going on with that reset... I ll ask if they can do something for 1.3...

 

In the meantime : properties get/set are actually method so you should use reflection to call the set_Instance(CommNetNetwork c) method.

Something like

CommNetNetwork.Instance.GetType().GetMethod("set_Instance").Invoke(yourNewInstance, null);

(the null is there because you call a static method)

@blowfish and this poster, many thanks for letting me know about the Unity singleton pattern and the reflection. I will go read up on those. 

I already filed a feedback issue on the bug tracker on this CommNet issue and it seems that it caught the attention of one of the KSP staff. So a fix to this could show up in the KSP 1.3 round.

I do not believe that is possible through the event itself.

If it is, you would have to manually hook into the OnMouseDown and OnMouseUp events of the button and not use the KSPEvent code itself.

So you'd have an empty game event, then in Start() hook into OnMouseDown and OnMouseUp.

I assume these events exist, they did in the old EzGUI system and are pretty typical, but I have no clue what they'd actually be called to find them.

Well, just the OnMouseUp event, the KSPEvent code is the OnMouseDown event I believe.

Not really important, I updated the Flag Rotate mod, right now the flag rotates in 5 degree increments, I was hoping to have it a smooth rotation, but not spending a lot of time on it

Thanks

How does one trigger a quickload? I looked at QuickSaveLoad, but that has only QuickSave().

Hello, I've been trying to add science data to the RnD archives for a couple of days now and I can't find the answer. I'm in a bit of a unique situation right now as I am working on Syncrio (a multiplayer extension mod). To be precise I'm trying to get a science archive from one client to another. I'm using the game event "OnScienceRecieved" to get the data on one client and "ResearchAndDevelopment.Instance.SubmitScienceData(dataAmount, subject)" to input it in the other client, but all I get on the 2nd client is "[Research & Development]: +5 data on Crew Report from LaunchPad. Subject value is 0.00" in KSP's debug log, it does not register the data in the RnD archives, meaning the same data can be gathered on the client1 and then gathered again on client2. Oddly enough, on the client that gathers the data they get this message "[Research & Development]: +5 data on Crew Report from LaunchPad. 2 Science added. Subject value is 0.00" the difference being the "2 Science added." part. I've read forum after forum looking for the answer and I've had no luck. Even the KSP API did not help much. I'm ether missing the obvious, or it just can't be done... Any help anyone can give will be greatly appreciated.

I'm playing around with VesselModules for the first time and I have some questions about how they work in the editor and in flight. I see in the API that you can set Activation.NonFlightScenes, this would make it run in the editor, right? Is there any way I can then save information in the craft file to be loaded when the vessel gets sent to the flight scene? Does VesselModule.OnSave() work like that in the editor?

Thanks!

[Booots]

Okay, new question: How do I create a physics connection akin to those made by attachment nodes? Note that I'm not trying to attach the two parts in the parts tree sense, I just want a physics joint between them with the same properties as an attachment node would have.

I went through the Kerbal Joint Reinforcement code and implemented their StrutConnectParts() method from KJRDecouplerReinforcementModule.cs, but it seems to have no effect. I see something that looks close-ish to what I want in KJRManager.cs in UpdatePartJoint(), but it looks like it goes above and beyond what I need and I can't quite figure out which parts I need or don't need. Anyone have some insight they can share? Maybe @ferram4?

[Diazo]

On the VesselModule, I wouldn't expect it to function in the editor, rather I'd expect that .NonFlightScenes flag to control whether it runs in other scenes where time passes, such as the main KSC view or the tracking station.

Have not tested that, but with what I know of how the editor works, I'm not sure how a VesselModule would work correctly....

So I would not expect VesselModule.OnSave() to do anything (as I don't think it runs) in the editor.

Can't help on the physics connection question, never touched that myself.

I have a question about the mission notes in custom missions.

I have had a look at this excellent thread:

My (one and only) contract parameter has this code:

cp.GetNotes () = "Param Notes."

The benefit is that the note show in flight:

The contract itself has this code:

c.GetNotes () = "Mission Notes."

But somehow both set of notes show up in the contract notes in the Mission Control building:

Do you know why that is happening, or if there is a trick to avoid it?

Can I destroy buildings in the KSC with plugin? If not, do they need to be in load range so that I can destroy them more...kinetically (via whack-a-kerb)?

Does anyone know how to get SOI and altitude (or at least situation) of an unloaded kerbal? I have the name and the ProtoCrewMember object, but I can't access a corresponding Vessel object (it is destroyed when unloading the vessel/exiting the scene).

Would finding it in FlightGlobals.Vessels work?

How do you reliably run code at game start?

Trying the KSPAddon startup attributes and [RuntimeInitializeOnLoadMethodAttribute] on a static function yields no joy. I'm trying to run some code to change some hardcoded values in the game for myself.

The earlier you can do is a KSPAddon set to immediate and the call you want in Awake. (static is a really bad idea if you use any Unity method)

I am attempting to write an extremely simple plugin to allow me to extract some information about the physical and orbital parameters of the stock celestial bodies. I am having some accuracy issues with a tool I created, and suspect the root of the problem might be that my raw data (taken from the wiki) is just slightly off.

What I hoped to do was simply fetch the data I needed (eg, Pe and Ap radius, orbital eccentricity, inclination, etc.) and print it to the debug menu/output log. From there I would just copy it out and process it manually.

Using the "Getting Started" thread, I've been able to put together a tiny "Hello World" add-on that starts when I enter the Tracking Station (). But I'm not sure where to go from there. I have no C# or Unity background, though I do have some experience with scripting and the like. Can someone provide some examples on how I can retrieve the information I'm after? I've found some instance fields and instance properties in the Orbit class that look like what I'm after, but I'm unsure of the *ahem* syntax *cough* that I need to use to fetch them.

Thanks for any guidance!

If you want to print information about the currently focused body in the tracking station, you can listen for an event that will fire to notify you when it changes:

Hi everyone, I've been playing around with VSR and @Nertea's Cryogenic tanks. In VSR there's a new cryogenic tank called CryoX which does NOT have zero boiloff function. I've found a plugin written by @Bluebottle that provides this. However, being OCD myself I found that in the CryoX series the cost of the XXL version is incorrect. I've tried changing this by modifying the config file. However, whenever I change this number the part does not load in game. Am I missing anything? The codes are below:

This is the modified version. I only changed the line which said "cost = 6400" to "cost = 16000"

Here's my code. I  guess I could have done a direct write to file, but I just copypasted from the output_log and used notedpad++ to remove any extraneous lines. Didn't end up using FlightGlobals.

@MaxZhaoI notice two odd characters just before PART in your post of the file where you changed the cost - if this is in the actual file it could cause this issue. Did your text editor add some extra characters? maybe it didn't save in a basic ASCII format? This would be the only thing I can think of.

Yeah I did notice it, however, the problem persists even after I've removed the characters. I don't know what those are but they don't appear in any other part cfgs.

I'm Having a problem creating my own generator. I want a small generator that can take ore and electricity and turn it into either liquid fuel, oxidiser or mono propellant as well as store the excess. I am new at modding KSP. I have made a model and texture that work but for some reason my code is wrong. Every resource value I enter appears in the game as 0. 

For example:

    MODULE
    {
        name = ModuleResourceConverter
        ConverterName = Mono Propellant
        StartActionName = Start Mono Propellant
        StopActionName = Stop Mono Propellant
        AutoShutdown = false
        GeneratesHeat = false
        UseSpecialistBonus = false
        INPUT_RESOURCE
        {
            ResourceName = ElectricCharge
            Rate = 0.5
        }
        INPUT_RESOURCE
        {
            ResourceName = Ore
            Rate = 0.5
        }
        OUTPUT_RESOURCE
        {
            ResourceName = MonoPropellant
            Rate = 0.95
