EventReceiver in the header file...

[Pythy Python]

Because I don't like all of my codes in my main.cpp, I decided to move EventReceiver code to receiver.h and receiver.cpp


main.cpp

Code: Select all

 
int main(){
    EventReceiver receiver;
 

receiver.h

Code: Select all

 
#ifndef RECEIVER_H
#define RECEIVER_H
 
 
#include "include/irrlicht.h"
 
using namespace irr;
 
 
class EventReceiver: public IEventReceiver{
    public:
        virtual bool onEvent(const SEvent& event);
 
        virtual bool keyCheck(EKEY_CODE keyCode) const;
 
        EventReceiver();
 
    private:
        bool keyIsDown[KEY_KEY_CODES_COUNT];
};
 
 
#endif
 

receiver.cpp

Code: Select all

 
#include "receiver.h"
 
 
bool EventReceiver::onEvent(const SEvent& event){
    if(event.EventType == irr::EET_KEY_INPUT_EVENT){
        keyIsDown[event.KeyInput.Key] = event.KeyInput.PressedDown;
    }
 
    return false;
}
 
bool EventReceiver::keyCheck(EKEY_CODE keyCode) const{
    return keyIsDown[keyCode];
}
 
EventReceiver::EventReceiver(){
    for(u32 i = 0; i < KEY_KEY_CODES_COUNT; ++i){
        keyIsDown[i] = false;
    }
}
 

I'm getting an error...

Code: Select all

 
main.cpp: In function 'int main()':
main.cpp:9:16: error: cannot declare variable 'receiver' to be of abstract type

include/IEventReceiver.h:446:15: note:  virtual bool irr::IEventReceiver::OnEven
t(const irr::SEvent&)
  virtual bool OnEvent(const SEvent& event) = 0;
 

What's my problem?

It's OnEvent with upper-case O. C++ is case sensitive.
