c# - How to set an initial value for UI_Knob?[Solved] -

i trying set initial value ui.extensions ui_knob see link ui.extensions repo ui.extensions bitbutcket

through searching have found maybe best way set initial value use simulated pointereventdata , pass script using executeevents, since ui_knob script uses mouse position set it's value.

--below code ui_knob--

i answered own question without using simulated mouse data. instead, added start() method mystartingangle() method. see below. chopped ui_knob's method rotation/setting value , injected own angle. still know how perform simulated mouse data if willing. appreciate input on solution well. reading!!

// add ui_knob script below initialization. // added here allow setting initial rotation/value.      void start(){         float myfirstangle = 180f;         mystartingangle (myfirstangle);     }      void mystartingangle(float angle){          _initrotation = transform.rotation;          quaternion addrotation = quaternion.angleaxis(angle, this.transform.forward);         addrotation.eulerangles = new vector3(0, 0, addrotation.eulerangles.z);          quaternion finalrotation = _initrotation * addrotation;           knobvalue = 1 - (finalrotation.eulerangles.z / 360f);          transform.rotation = finalrotation;         invokeevents(knobvalue + _currentloops);          _previousvalue = knobvalue;      }
