Add Mouse behaviour

[jesus]

Hi,
i wrote this small script around a tutor source to free mouse (e.g. to close window or use GUI elements)....

Code: Select all

#include <stdio.h>
#include <irrlicht.h>


using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;

#pragma comment(lib, "Irrlicht.lib")

class EngineState {

        bool freemouse;
        IrrlichtDevice *device;
        ICameraSceneNode *camera;

public:

        void init( IrrlichtDevice *_device, ICameraSceneNode *_camera ) {
                device = _device;
                camera = _camera;
        }

        bool isFreeMouse() {
                return freemouse;
        }

        void setFreeMouse( bool _free ) {
                freemouse = _free;
                device->getCursorControl()->setVisible( freemouse );
                camera->setInputReceiverEnabled( ! freemouse );
        }

};

class MyEventReceiver : public IEventReceiver
{

        EngineState *state;

public:
        MyEventReceiver( EngineState *_state ) {
                state = _state;
        }
