problem with my parts and gui

[kurator125]

I have part with plugin and all part have force. I can change this force in gui and when i change force it only one part have new force. How make parts list and how control all parts? I can't find this on wiki.

using UnityEngine;
using PluginTutorial.Extensions;
using KSP.IO;

namespace PluginTutorial
{
    public class PluginTutorial : PartModule
    {
        private static Rect _windowPosition = new Rect();
        private GUIStyle _windowStyle, _labelStyle;
        private bool _hasInitStyles = false;
        public  float force = 10f;

        public override void OnStart(PartModule.StartState state)
        {
            if (state != StartState.Editor)
            {
                if (!_hasInitStyles) InitStyles();
                RenderingManager.AddToPostDrawQueue(0, OnDraw);
            }
        }


        public override void OnSave(ConfigNode node)
        {
            PluginConfiguration config = PluginConfiguration.CreateForType<PluginTutorial>();

            config.SetValue("Window Position", _windowPosition);
            config.save();
        }

        public override void OnLoad(ConfigNode node)
        {
            PluginConfiguration config = PluginConfiguration.CreateForType<PluginTutorial>();

            config.load();
            _windowPosition = config.GetValue<Rect>("Window Position");
        }

        public override void OnUpdate()
        {
            if (this.vessel == FlightGlobals.ActiveVessel)
            {
                this.rigidbody.AddRelativeForce(Vector3.up * force * FlightInputHandler.state.mainThrottle);
            }
        }


        private void OnDraw()
        {
            if (this.vessel == FlightGlobals.ActiveVessel && this.part.IsPrimary(this.vessel.parts, this.ClassID))
            {
                _windowPosition = GUILayout.Window(10, _windowPosition, OnWindow, "This is a title", _windowStyle);

            }
        }
        private void OnWindow(int windowId)
        {
            string sSila;

            sSila = force.ToString();
            GUILayout.BeginHorizontal();
            GUILayout.Label(sSila, _labelStyle);
            GUILayout.EndHorizontal();

            if (GUI.Button(new Rect(25, 50, 30, 30), "+"))
                force += 10;
            if (GUI.Button(new Rect(75, 50, 30, 30), "-"))
                force -= 10;

            GUI.DragWindow();
        }

        private void InitStyles()
        {
            _windowStyle = new GUIStyle(HighLogic.Skin.window);
            _windowStyle.fixedWidth=250f;
            _windowStyle.fixedHeight = 250f;

            _labelStyle = new GUIStyle(HighLogic.Skin.label);
            _labelStyle.stretchWidth = true;

            _hasInitStyles = true;
        }
    }
}

Try making your force a static variable

[kurator125]

thanks, it work but how make part lists? and how to control every part of the singly? I do not want the code, only suggestions.

You want to control all parts of a specific vessel? Guess the usual way most modders would do it is by looping though vessel.parts, check whether it has your part module and do whatever they want with it. Ofc doing sth like this frequently does not make the game scale very well. Just imagine a vessel with 10k parts... well, code like this is one of the reasons we most likely won't have such large vessels.

Just using a static variable isn't good, since it can create issues with saveing/loading and you cannot have different values for different vessels.

Another approach could be to keep a static dictionary with VesselIds or even PartIds as index up to date and look up your object whenever you need it. Dict's aren't the fastest, but they pretty much do they job in the same speed no matter how many objects are in them.

Anyway, i think in your case it might be simpler to keep a ref to a single data-object per vessel in all your part modules. Sth like this:

public class TutDataObject{
  public float force;
}
public class TutPartModule: PartModule{
  TutDataObject tutData;
  bool isPrimary = false;
  void Start(){ // or awake?
    tutData = vessel.parts.SelectMany(part => part.Modules.OfType<TutPartModule>()).Where(tutMod => tutMod.tutData != null).FirstOrDefault();
    if( tutData == null ){
      isPrimary = true;
      tutData = new ...
    }
  }
  void OnSave(...){
    if(isPrimary){
      //save data...
    } 
  }
  void OnLoad(...){
    // load data if there is such a node
  }
}

Ofc its not that easy... since a vessels can be split into multiple vessels, e.g. by staging and merged by e.g. docking. A way to handle such situtations would be to store the latestest VesselId in TutDataObject and check whether its up to date via the GameEvents.onVesselChange.
