/*
* StelController: Part of the Stellarium-Unity bridge tools (c) 2017 by Georg Zotti and John Fillwalk.
*
* This module takes sole responsibility for communication with a running instance of Stellarium.
* Any setter/getter methods (time, location, longitude/latitude, Field of view, property switching etc.) should be implemented here.
* The GUI (IDEA Labs) should communicate with this module only and not with other JSON tools.
*
Instructions:
1. Attach the scripts StelController, StelSkyBox, StelTriggers, StelMouseFoV to an empty GameObject "Stellarium" with a Light.
2. Start Stellarium and activate RemoteControl plugin before starting the Unity game. Run the script once from Stellarium to create the Skybox textures.
3. During gameplay, press F11 to update the Skybox with whatever Stellarium shows now.
F12 to toggle Skybox vs. Spout mode
F8/F9 to move 1 hour back/forward
See StelKeyboardTriggers for the complete list.
Further functionality can be implemented using the remote control API mentioned above. For example. the mouse-wheel-based FoV script can set FoV in Unity and Stellarium.
Note: You must call the available IEnumerator functions as Coroutines! E.g. StartCoroutine(mouseZoom.setFoV(fieldOfView));
History:
2017 first workking version
2018-01 GZ fixed for Unity 2017.3: WWW POST operations with WWWForms failed, no data were transferred. The only working solution is UnityWebRequest with a Dictionary payload.
2018-01 GZ adapted to requirement to run the scene also in WebGL: StreamingSkybox. This should eventually replace the StelSkybox.
2018-09 GZ adapt to changed JSON interface from Stellarium to use double/boolean/string, not string-only.
