Hi, my name is Sasha. I'm in GAM670

Force Feedback

Add this to Configuration.h:

#define IDC_NOFF //number

In iInput.h, add line 1 in the iJoystick class In Input.h, add line 2 in the Joystick class In Input.h, add line 3 in the Joystick class

1.
public:
   virtual void updateForce(float, double, int) = 0;
2.
  int feedBackOFF;
  LPDIRECTINPUTEFFECT centre;
  LPDIRECTINPUTEFFECT ffEffects;

3.
  public:
     void updateForce(float factor, double time, int direction);

In Input.cpp, add the following to the Joystick constructor

 ffEffects = NULL;
 centre = NULL;
 feedBackOFF = 0;

add this in Joystick::interrogate function:

 DIDEVCAPS didcaps;
     didcaps.dwSize = sizeof didcaps;
     if(SUCCEEDED(didInter->GetCapabilities(&didcaps)) &&
       (didcaps.dwFlags && DIDC_FOREFEEDBACK){
        EnableWindow(GetDlgItem((HWND)hwnd, IDC_NOFF), TRUE);   
        }
     else{
        EnableWindow(GetDlgItem((HWND)hwnd, IDC_NOFF), FALSE);
     }

add this in Joystick::setup function:

 feedBackOFF = !!(flags & 8);

change the SetCooperativeLevel in setup to check for device exclusivity

   else if (FAILED(joystick->SetCooperativeLevel((HWND)hwnd,
 (feedBackOFF ? DISCL_NONEXCLUSIVE : DISCL_EXCLUSIVE) | DISCL_FOREGROUND)))

add this line after (!zAxisOn)

if(feedBackOFF)
   centre = NULL;
