Testing multi-display

[Xavier513]

I'm trying to play KSP on more than one monitor, with different  content in each monitor.

I successfully achieved this on two monitors, but I encountered an issue, and I need some help: the vessel disappears in the first monitor.

This is how I enable the second monitor:

1, Connect another monitor to the PC running KSP (via HDMI port).

2, Compile following codes and start KSP, this addon will take effect in Flight scene.

	[KSPAddon(KSPAddon.Startup.Flight, false)]
    public class DisplayAddon : MonoBehaviour
    {
        private static bool bottonClicked;
        private static global::Vessel vessel;

        private static Camera galaxyCamera;
        private static Camera scaledSpaceCamera;
        private static Camera camera00;

        private static int SecondDisplay = 1;
        public void Start()
        {
            vessel = FlightGlobals.ActiveVessel;

            Display.displays[SecondDisplay].Activate(); // Activate the second display
				
				 // Copy in-game cameras
            galaxyCamera = new GameObject().AddComponent<Camera>();
            galaxyCamera.CopyFrom(Camera.allCameras.FirstOrDefault(cam => cam.name == "GalaxyCamera"));
            galaxyCamera.name = "GalaxyCameraCopy";

            scaledSpaceCamera = new GameObject().AddComponent<Camera>();
            scaledSpaceCamera.CopyFrom(Camera.allCameras.FirstOrDefault(cam => cam.name == "Camera ScaledSpace"));
            scaledSpaceCamera.name = "scaledSpaceCameraCopy";

            camera00 = new GameObject().AddComponent<Camera>();
            camera00.CopyFrom(Camera.allCameras.FirstOrDefault(cam => cam.name == "Camera 00"));
            camera00.name = "camera00Copy";
				 
           // New cameras render to the second display
            galaxyCamera.targetDisplay = SecondDisplay;
            scaledSpaceCamera.targetDisplay = SecondDisplay;
            camera00.targetDisplay = SecondDisplay;
        }

        public void FixedUpdate()
        {
            if (bottonClicked) 
            {
                camera00.transform.position = new Vector3(-5.5f, 0.7f, -2.0f); // Place the camera at somewhere near the vessel
                camera00.transform.LookAt(vessel.CoM);

                galaxyCamera.transform.rotation = camera00.transform.rotation;
                scaledSpaceCamera.transform.rotation = camera00.transform.rotation;
            }
        }
    }

3, Load a save, load a vessel, then enable addon.

Please take a look at these 4 images: https://imgur.com/a/uiOz9pn

The first 2 images are contents in two monitors when the addon IS NOT activated.

The last 2 images are contents in two monitors when the addon IS activated.

As you can see, in the third image, the vessel is not shown.

Does anyone know how to fix this? Thanks a lot!

OK, my mistake, some lines of code weren't commented out correctly.

The code above works fine, now.

@Xavier513 do you happen to have a compiled dll of this?... I would be ineterested in testing it...

hi, @Stone Blue, thanks.

Sorry, I'm testing this function along with many other WIP features in my project, so it's not quite convenient to provide a DLL.

But the codes above are basicly all the codes needed for this feature, for now. 

You can

1, create a new project in Visual Studio,

2, create a C# file with those codes.

3, add references of Assembly-CSharp.dll and UnityEngine.dll to project.

4, then you can compile it to generate a DLL, 

 

Besides, you have to add a button somewhere(e.g. some part's right click menu) to set "bottonClicked" to true, or activate the addon in other ways.
