so for some reason my event receiver doesnt work....partly
the keyboard works, but the mouse buttons are always up...whats wrong?

Code: Select all

class MyEventReceiver : public IEventReceiver
{
 public:
   bool OnEvent(const SEvent& event) 
   {
     if(event.EventType == irr::EET_KEY_INPUT_EVENT)
     {
       keys[event.KeyInput.Key] = event.KeyInput.PressedDown;
       return true;
     }
     if(event.EventType == irr::EET_MOUSE_INPUT_EVENT)
     {
        mouse[event.MouseInput.Event]=event.MouseInput.Event;
        return false;
     }
 return false;
   }
};

then i initialise the arrays

Code: Select all

  for(int q=0; q<irr::KEY_KEY_CODES_COUNT; q++) keys[q] = false; 
for(int q=0; q<EMIE_COUNT; q++)  mouse[q]=false;

and check for events in my while cycle

Code: Select all

if(mouse[EMIE_LMOUSE_PRESSED_DOWN ]){cout<<"L";}
if(mouse[EMIE_LMOUSE_LEFT_UP ]){cout<<"U";}

Code: Select all

        mouse[event.MouseInput.Event]=event.MouseInput.Event;

That line looks strange ... shouldn't it be "= true"?

well when you do this

Code: Select all

mouse[event.MouseInput.Event]=true;

you can press the mouse button once and it always remains true as if the button was kept pressed forever

Something is strange in that scope, can you tell me what's wrong with that?

Code: Select all


     if(event.EventType == irr::EET_MOUSE_INPUT_EVENT) 
     { 
        mouse[event.MouseInput.Event]=event.MouseInput.Event; 
        return false; 
     }

Maybe it should be return true; !?

Uhh...yeah about that. Your going to have to manage that yourself by writing to the variable when a change occurs. So you must maintain that.

If your having trouble, then check out the event receivers around the forums built for beginners:

MastEventReceiver
CIrrEventReceiver

I wrote the CIrrEventReceiver...I believe that is enough of an answer. And if he can't pool through the CIrrEventReceiver/MastEventReceiver source code and find what he needs, then whatever. It only took me 2 seconds to find the answer in the MastEventReceiver source which is posted in the topic.

Here is a small tidbit:

Code: Select all

//Left Mouse Button Rleased 
            if (event.MouseInput.Event == EMIE_LMOUSE_LEFT_UP) 
            { 
               // 
               if (mouseButtonState[0] != UP) 
               { 
                  mouseButtonState[0] = RELEASED; 
               } 
            } 

            //Middle Mouse Button Pressed 
            if (event.MouseInput.Event == EMIE_MMOUSE_PRESSED_DOWN) 
            { 
               // 
               if (mouseButtonState[1] == UP || mouseButtonState[1] == RELEASED) 
               { 
                  mouseButtonState[1] = PRESSED; 
               } 
               else 
               { 
                  mouseButtonState[1] = DOWN; 
               } 
            }
