Showing a Kerbal portrait in a GUI.Window

[simon56modder]

Hi,

How can I create a kerbal portrait to show in a window ?

(portraits like in tutorials/scenarios or at the beginning of a new game)

I want a Wernher portrait and I want to be able to play emotes.

I've tried using KerbalInstructor but I can't find a way to make it work.

This should get you there:

[KSPAddon(KSPAddon.Startup.MainMenu, false)]
public class WindowInstructor : MonoBehaviour
{
    private const int PortraitWidth = 128;
    private const int PortraitHeight = 128;

    private KerbalInstructor _instructor;
    private RenderTexture _portrait;
    private Rect _windowRect = new Rect(250f, 250f, 128f, 128f);
    private Dictionary<GUIContent, CharacterAnimationState> _responses;
    private int _selectedResponse = 0;

    private void Start()
    {
        Resources.FindObjectsOfTypeAll<KerbalInstructor>()
            .ToList()
            .ForEach(instructor => print("Instructor: " + instructor.CharacterName + ", prefab: " + instructor.name));

        _instructor = Create("Instructor_Gene");

    }


    private void OnDestroy()
    {
        if (_portrait != null)
            _portrait.Release();

        if (_instructor != null)
            Destroy(_instructor.gameObject);
    }


    private void OnGUI()
    {
        _windowRect = KSPUtil.ClampRectToScreen(GUILayout.Window(GetInstanceID(), _windowRect, DrawWindow, "Window Title",
            HighLogic.Skin.window));
    }


    private void DrawWindow(int winid)
    {
        GUI.skin = HighLogic.Skin;

        GUILayout.BeginHorizontal();
        {
            GUILayout.FlexibleSpace(); // to center portrait in case window stretches beyond portrait width
            GUILayoutUtility.GetRect(PortraitWidth, PortraitHeight);

            if (Event.current.type == EventType.Repaint)
                Graphics.DrawTexture(GUILayoutUtility.GetLastRect(), _portrait);

            GUILayout.FlexibleSpace();
        }
        GUILayout.EndHorizontal();

        _selectedResponse = GUILayout.SelectionGrid(_selectedResponse, _responses.Keys.ToArray(), 4);

        if (GUI.changed)
            _instructor.PlayEmoteRepeating(_responses[_responses.Keys.ToArray()[_selectedResponse]], 1f);

        GUI.DragWindow();
    }


    private KerbalInstructor Create(string instructorName)
    {
        var prefab = AssetBase.GetPrefab(instructorName);
        if (prefab == null)
            throw new ArgumentException("Could not find instructor named '" + instructorName + "'");

        var prefabInstance = (GameObject)Instantiate(prefab);
        var instructor = prefabInstance.GetComponent<KerbalInstructor>();

        _portrait = new RenderTexture(PortraitWidth, PortraitWidth, 8);
        instructor.instructorCamera.targetTexture = _portrait;

        _responses = instructor.GetType().GetFields(BindingFlags.Public | BindingFlags.Instance)
            .Where(fi => fi.FieldType == typeof (CharacterAnimationState))
            .Where(fi => fi.GetValue(instructor) != null)
            .ToDictionary(fi => new GUIContent(fi.Name), fi => fi.GetValue(instructor) as CharacterAnimationState);

        return instructor;
    }
}

Unfortunately I can't code at all, is there any possibility you could make available what you have in the screenshot, it could be used to green-screen a live instructor commentary onto a video.

Is your project using .NET v3.5? Unity, and by extension, KSP, uses .NET v3.5, and if your plugin doesn't also use 3.5, then the assembly loader will screw up.
