Mouse wheel question

[aiaf]

Hi,

 

Im getting the mouse wheel index(in the main loop) and use this in a menu:

selectedDirection = (int)window->GetMousePosition().z;

 

There is a function, or other way, that detects that Wheel moved ?

 

Something like:

if(window->MouseWheelHit()) {

do something

}

edit: Noticed you need it for C++ so this won't help much

You have to check the mouse position Z component

 

class SomeClass
{
float _lastMZ;
...

void Init()
{
 _lastMZ = Window::GetCurrent()->GetMousePosition().z;
}

void UpdateWorld()
{
 auto mz = Window::GetCurrent()->GetMousePosition().z;
 if ( mz != _lastMZ )
 {
		 // mouse wheel moved
		 // distance is mz-_lastMZ
		 _lastMZ = mz;
 }
}
};

Thanks seems im tired and lazy, i wanted a window->MouseWheelHit() event

class MouseSensorListener
{
public:
   virtual void onmousewheelHit( float distance ) = 0;
};
class MouseSensor
{
private:
   float _lastMZ;
   MouseSensorListener _listener;
public:
   void init()
   {
    _listener = nullptr;
    _lastMZ = Window::GetCurrent()->GetMousePosition().z;
   }
   void register( MouseSensorListener* listener )
   {
    _listener = listener;
   }
   void unregister()
   {
    _listener = nullptr;
   }
   void update()
   {
    auto mz = Window::GetCurrent()->GetMousePosition().z;
    if ( mz != _lastMZ )
    {
	    // mouse wheel moved
	    // distance is mz-_lastMZ
	    if( _listener )
	    {
	    _listener->onmousewheelHit(mz-_lastMZ);
	    }
	    _lastMZ = mz;
    }
   }
};
class SomeClass :
   public MouseSensorListener
{
public:
   void init( MouseSensor* sensor )
   {
   sensor->register(this);
   }
   void onmousewheelHit( float distance )
   {
    // Mouse wheel moved 'distance'
   }
};
